I see a lot of questions on drivers and devices for Virtual machines. (Hyper-V, VMware, "XP mode", Virtual PC, etc)
Its important to understand that the devices the virtual machines see are not the actual hardware in the machine.
That is to say...the virtual machine might know that there is a network card available to use, but it doesn't know that the physical network card is a Broadcom 3c905 (for example). The virtual machine thinks that it is a pre-defined device that is written specifically for use in the virtual machine.
Same goes with other hardware, your Nvidia 9800 GTX would show up in the VM as a totally different piece of hardware. And this virtual piece of hardware does not have the features or power of the 9800 GTX nor does it require its device drivers.
Virtual machines use 2 types of devices. Emulated and Synthetic.
Emulated - Drivers/Devices that require a lot of physical box overhead to process for the virtual machine. Basically there is a lot of translation that the hypervisor (virtual pc, hyper-v, etc) must perform for the virtual device to utilize the physical device. These are the types of devices/drivers you will see used in Virtual PC and MS Virtual Server 2005 and some others.
Synthetic - Virtual Devices/Drivers that are highly optimized to perform very seamlessly with the underlying physical device. Hypervisor intervention/translation is kept minimal and therefore performance is greatly improved. Virtual machines using synthetic drivers are often said to be "enlightened". These are generally seen in bare metal hypervisors like Hyper-V and ESXi.
The important thing to take away from this post is that the actual physical devices in your computer are NOT what the virtual machine sees.
The network traffic from your virtual machine is passing through the physical network card, but the virtual machine will "see" a totally different device than what is actually in the computer. This goes for any device.
I have installed Microsoft Virtual PC in my new sony viao windows 7 computer. Then, I installed XP computer, vista computer and windows 2003 server computer in my MICROSOFT VIRTUAL PC. Now, I want to connect 3 computer in network. so that I can ping each computer with other. I also want to control things in xp and vista computers using windows 2003 computer.
I have 3 Virtual Machines on my 2TB drive, but it's close to full already and most of them are right at the end of the disk, where the drive is slowest. This doesn't make for an overly enjoyable experience when in use so, if possible, I'd like to move the VMs to the start of the drive in an effort to speed them up somewhat.I've got Auslogics Disk Defrag Professional, which allows for system files to be moved to the start of the drive, but I can't see an option for moving files of my choosing.Getting another drive and copying files across isn't an option either, as I don't have one to hand.
Currently I'm building a server for a client who wants to run several copies of Diablo 3 on multiple Virtual Machines.Further, they also need the ability to use a hardware unity function.
I can not access any of these storage devices or virtual drives.The devices work perfectly on other computers.I am sure that there is a problem with permissions.I tried everything from other forums, from cmd commands to local protocol changes,and when i tried to change permision of the drives in My Computer i get acces denied.I am on the only user account which is administrator too.
I have a network of about 90 computers connected together and i am currently running server 2003. Now when i go to network place on my xp machine, i am able to see all of my computers that are connected together. But when i go to network place on my window 7 machine, i am only seeing some of my window 7 computers and not the xp computers. The network discovery is turned on, on all of my window 7 and still nothing.
i have an old windows xp pc that my son uses for chat and homework for printing. the problem i,ve now got is he and a friend of his has formatted the pc and installed windows 7.i do know that some of the devices do not have windows 7 drivers because i once checked when he asked me could he have win 7 on it. i didnt bother to upgrade the pc as there was no need.the problem he now has is that everything works but there is nothing on the monitor. it says no input. i have researched on google and the answer i get is because there is no win 7 driver for the nVidia GeForce FX5200.
when i plug in any thing into my usb plug it will say it failed to load drivers and then it shows up onder other devices in the computor management screen. It will show the name of the device but will not find the drivers. I can plug in the same devices into my lap top that has same windows7 on it and they will work.
I am not at all very good with computers, it even took me a minute to figure out my OS lol! but i have a serious problem: My USB drivers are no longer reading my phones and other devices the message i get is "USB Device Not Recognized", When i click the message and go through the troubleshoot it gets no where. It's like my computer doesn't even realize that the devices and drivers are malfunctioning, also i don't know if it is related but it seems like files, apps and folders are constantly being deleted without my consent and no one else has access to my pc. i suspect foul play hidden in my system.
I've just setup/installed Windows 7 32-Bit and looks like everything is OK but I installed a virtual CD program/s (i.e. Daemon Tools, PowerISO and or MagicISO) my system is not detecting the virtual CD's that Daemon Tools, PowerISO and or MagicISO have created. can you suggest any procedures for this? or do i need to install something or update my drivers?
A couple days ago, I installed Windows 7 (through MSDNAA).
I have a problem with some devices. The situation can be seen here:
I tried updating driver software through windows and it said it was unable to find drivers
I have no idea what the "Unknown Device" may be. The "Multimedia Video controller" I'm guessing is my Nvidia graphics card? The Mass Storage Device I think is my Magicgate memory card slot, but I'm not sure.
I have an Nvidia 8400M GT graphics card and judging by what I've seen on the resolution window (and device manager), I'm currently running on my standard VGA graphics device, and not my Nvidia.
I manually searched for the drivers for my graphics card off the Nvidia site, but every time I try to install it, I get this messege
]I've already tried reformatting and reinstalling windows 7, now I'm running out of ideas. Can anybody please help?
I'm using a Sony Vaio TP3 computer. It's a "desktop" with laptop components and was initially running on Vista.
I upgraded to Windows 7, but I have a few software I installed on Virtual PC 2007 before. I use XP mode but can't find a way to use the virtual HD created with Virtual PC 2007. Is there a way to convert the virtual HD so that XP mode can recognize?
I have been unable to connect to anything on my wired network, for about the last week. I don't remember making any changes however, I just became unable to connect.I having done a little troubleshooting.1. I can connect to the shares of my Windows Home Server if I use the IP address. The name does not resolve.2. Flushed DNS and restarting DNS server. Flushing DNS works on one client, to allow browsing by the name & restarting DNS works on the other. However neither works after a restart.3. Only my Wifi clients are experiencing this issue. My wired clients, desktops, PS3, Xbox 360, and Boxee can connect perfectly.This issue is not limited to my server. I can't connect to shares on my desktop, nor print to my wired printer.Some network background:I have DSL through CenturyLink and have a Linksys E2000 router.
Got a new Windows 7 Enterprise 64 bit machine, found that it did not come with virtual PC. Downloaded the critical patch Windows6.1-KB958559-x64-RefreshPkg.msu and installed it. Windows Virtual PC shows up in my Start Menu. Good so far. I go through the steps to create a virtual machine and use the option to 'use an existing vhd file' and when I click 'Create' I get the above pop-up message "Cannot attach the virtual hard disk to the virtual machine. Check values and try again". A factual message but completely useless as with all error messages from Microsoft. I have tried the following:1. When I attach that vhd using Disk Management, it mounts in drive E:, I can see the files and browse the dirs in E:. In the Disk Management View, the drive shows up as 127 Gigs but 107 is unallocated space. The physical size of the vhd is only 25 Gigs2. Others in my company were able to create the virtual machine with the same vhd, checked the byte size and timing, so nothing is wrong with the vhd file itself.
3. Tried to create after shutting down all virus protection including the Micorsoft antimalware protection service. No luck4. Tried Vhd resize to resize the vhd to a smaller size (since it showed up in disk management as 127 Gigs, I thought maybe it was that size), but VHDResizer could not open the input file, gave an errors "Can only load fixed or dynamic drives"
I have two HP laptops. One came with Win 7 Pro while the other has home edition. Is it possible to install the pro version on both the machines with the same installation disk.
I think since I own both the laptops and their respective OS, I might try to do that. The main reason is one has a clean installation disk while the other has OS image with all the bundled HP bloatwares which I dont want to go thru.
I have a home network with 7 or 8 XP machines. All are on the same workgroup. All share EVERYTHING. All have passwords. All are logged in with an ADMINISTRATOR account. All can see each other on the network. They all talk to each other just fine. All the GUEST accounts are turned ON.I loaded Windows 7 on a machine, and turned on sharing for drive C: I gave everyone ALL permissions. I also went into the Network and Sharing Center. I had no idea what a "HomeGroup" was, so I went a few more menus deep and found the Workgroup setting. I set that up with the name of my workgroup.From the Windows 7 machine, I can see all the XP machines on the network, and they can see the Windows 7 machine. But when I try to view anything (drive C: , for example), I get the "you might not have permission to view this network resource....". I get the same thing when I try to log on to the Windows 7 machine from the XP machines.Since I can't log on to my XP machines, I also can't connect to, and use the printers attached to them.I basically want a big, open, flat network. No security at all between machines. What do I need to do?
I have used ghost before to image XP PCs over the network, but have yet to try either Windows 7 or an OEM Operating System (xp was an enterprise license).
My Qs: Is it legit to ghost OEM PCs? I have 60+ new PCs, with OEM Windows 7. I was thinking that I could take one PC, set it up the software etc then push the image. I would then change the license key to the one on the box.
Is this correct? If all the systems are the same, do I need to sysprep? I have heard horror stories of system preping Windows 7 -
So I have a network with 3 computers, a readynas, and multiple network printers.
Two machines have 64 bit RC 1, one has XP.
XP machine can see both Seven machines, and NAS.
64 bit machine one can see everything as well.
64 bit machine two could see everything when I did the first install of RC. I reinstalled to fix some boot manager issues, and now it cannot see the XP machine, nor the NAS from windows explorer. I can connect to the readynas through it's IP address in a browser no problem, I have full internet and networking between it and the first 64 bit machine.
No homegroup is set up on either seven machine. The network is set to Home. Drivers are installed for the Ethernet properly, latest drivers.
I looked through settings and everything seems to be gravy. What am I missing. Nothing changed between the two installs except 18 hours of time.
I have 2 machines MACHINE1 and MACHINE2 running Windows 7 Ultimate x64 and am trying to map to the D: drive from MACHINE1 machine on to MACHINE2. I enter \MACHINE1D$ as the drive address but then it tells me access is denied. The account name and password is the same on both machines (no domain here) and I have tried specifying MACHINE1Qu0ll as the user name but it still won't let me map the drive.
Curiously I can see the D: drive when I double click on MACHINE1 in Network but I cannot write to it without "Access denied" messages again.
I have 4 machines on a work network. All machines are Windows 7 Pro 64bit. Password sharing is on. All computers have only 1 user account you can locally log in from.
Sharing used to work perfectly by entering the username/password of the computer you were trying to access. I did not need to have the same local username/password on all.
Now on one of the computers I enabled the Guest account and I can no longer access it from the network. All other computers work fine.
Network printer and two wired XP machines not discovered by new Win7 laptop. System says I'm in "workgroup". My XP machines see the laptop in "network places", but laptop with Win7 does not see the XP machines or an ip/ipp network printer. I can print to the printer if I plug on hard wire ethernet, but can not print if I unplug. Still can not see either XP computer or Printer.
I have VPN service running on my Linksys DD-WRT router at home, so I can VPN back into my home network when using unsecured wireless internet on travel. I also have remote desktop port forwarding to my home machine if I want to just remote desktop in without using the VPN. However, often times I will VPN in, then remote desktop to my machine. Lately, I can VPN in, but can't see any other machines on the network so remote desktop to the machine's 192.168.x.x address on the local network doesn't work. I used to be able to do this and I'm not sure what has changed. The home machine runs Windows 7 and the laptop I use on the road for VPN'ing back in runs Windows XP. why after I VPN in to the home network I can't see any other machines on the network anymore? I have a folder shared on the home machine that I'd like to map to my laptop once I've VPN'ed in but can't do that either since it can't see the machine.
I've got all the sharing options enabled on the Windows 7 machine as well as the XP machine. Network discovery is turned on as well. No clue what has happened with this. The DHCP pool is 192.168.1.2-150 and the VPN pool consists of only 2 addresses of 192.168.1.160 and 192.168.1.161.
I've recently installed some windows 7 machines on our network and they don't seem to be getting valid network configs. It sees the correct DHCP info and DNS servers and you can ping the gateway and other computers on the same subnet but when you try to ping other subnets or out to Google it won't go.
You can see local computers on the same subnetwork and even view webpages on the server on the subnet but everything else network wise outside of the subnet doesn't work.
We have a subnet firewall and it is set to allow everything on the trust side out on any port to any computer. I've even made a rule that let everything in from the outside (untrust) on every port to these windows 7 machines and they still don't get an identifiable network.
I am running the 7100 RC Build and when I go to network it shows all my machines. One of these is a media streamer (HDX 1000). I can access all machines by double clicking on them however when I do that with the HDX it times out and says HDX is inaccessible.
I am using "home" network but not joined a homegroup. Network discovery is on. File sharing on. Contrlled by username and password NOT by homegroup.
I also think I have it set to send LT and NTLM ntlm v2 is applicable in the local security policies. The windows 7 machine has a static ip set.
I should also not I can ftp into the HDX and I can ping it and get replies. UNC path in explorer bar does not work either nor can I map any of the shared folders on it.
I have a desktop and a laptop. The desktop specs are listed on my System Specs. Some remotely related laptop specs: [code] Both are running Windows 7 Ultimate x64, dual booted with Kubuntu Linux x64. Would it be possible to have a single VM running on both machines such that its guest OS thinks it is running on an 8-core, 16-threaded CPU? (Both PCs are connected to the same LAN)
