Hi all,

 

I want to setup a Windows VM using KVM and am looking for a working config file. I don't want any fancy pass through gubbins, I just want to be able to install it and access it via rdp.

 

I did have one running under Xen, but now that I've switched to non-Xen mode I want to start again.

 

Holding my hands up at the start - I've not yet googled it - hoping that someone out there will have a config I can use out of the box. ALl of the examples I've seen here in the forums seem to be using pass through etc.

You can use mine from here http://lime-technology.com/forum/index.php?topic=33927.0 just remove these lines ( for pass trough)

 

<qemu:commandline>
    <qemu:arg value='-device'/>
    <qemu:arg value='ioh3420,bus=pcie.0,addr=1c.0,multifunction=on,port=1,chassis=1,id=root.1'/>
    <qemu:arg value='-device'/>
    <qemu:arg value='vfio-pci,host=04:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on'/>
    <qemu:arg value='-device'/>
    <qemu:arg value='vfio-pci,host=04:00.1,bus=root.1,addr=00.1'/>
    <qemu:arg value='-device'/>
    <qemu:arg value='vfio-pci,host=00:1d.0,bus=pcie.0'/>
  </qemu:commandline>

 

Works great with RD

Thanks.

 

I'm guessing that as I don't want passthrough or anything I can ignore the other parts of your post? I just need the domain cfg file (modified to remove the section you highlighted)?

Yes :-) just use the xml file.

 

During install you need to load virtio driver from the "other cdrom", since the windows HD will not show up, thats normal using "virtio"

 

/Peter

Tried to get a Windows 8.1 VM up and running after upgrading my rig. Would like to just get it started before I attempt any passthrough. Getting the following error

 

error: Failed to create domain from Win8.xml

error: Cannot get interface MTU on 'br0': No such device

 

Here are the files contained on my VM drive

root@Tower:/mnt/VM# ls
Win8.xml  Windows8.qcow2  en_windows_8_x64_dvd_915440.iso  virtio-win-0.1-81.iso

 

Here's my XML

Any suggestions? Very inexperienced with virtualization, especially using the command line.

Whats your bridge name ? do a output of ifconfig and see if you have br0

 

Ah okay, got it working by changing br0 to docker0. Thanks for the help!

Okay got the VM up and running and I was able to use TightVnc to access and install Windows 8 but after installation is complete I have no network connectivity inside the windows VM. Any help is appreciated, XML below

Did you install all the virtio drivers ? check all your devices

 

//Peter

I believe so. I installed all the drivers located in the Win8/AMD64 directory. I am using docker0 as a bridge, do I have to create a br0 bridge instead? Not quite sure how to do that....

 

Here's the output of ifconfig

docker0 is wrong bridge to use!

 

 

go to unraid settings network and activate the bridge, give it a name, 'br0' for example, and use br0 in the xml file.

 

should then looks like this........

Ahh, silly me. That totally did the trick. Thanks for your patience  Now time to try some passthrough.
