My windows 10 VM has been locking up again. :'(  It was running perfect with no lockups until yesterday and now it has done it 4 times. I'm not sure what is causing it now.  I was just moving chrome across the screen when it happen last. Nothing has really changed on the system.

 

 

It also looks like there is a bug in the web gui for the log files if there is a space in the name for the VM:

/usr/bin/tail: cannot open '/var/log/libvirt/qemu/Windows' for reading: No such file or directory

/usr/bin/tail: cannot open '10.log' for reading: No such file or directory

Check to see that your GPU/audio is still using MSI. Driver updates can reset them.

 

Quickest way to check is to look in Device Manager, on the "Resources" tab for your device. IRQ should be set to a negative value.

I have done no updates and the MSI is still on.

My windows 10 VM starting locking up, and I noticed it was during heavy disk activity. I used a SSD with unassigned devices, I switched SSDs and it's good now. I don't know your setup, what is your VM stored on?

Mine is on a 1tb WD blue drive. Now it is locking up when it is sitting idle. I was on overnight and it was locked up in the AM

Update: I had installed a win7 image and it was blue screening with a GPU error. Win10 would just go to a black screen. I have upgraded my GPU to a gtx 970 and so far so good with Windows 10.
