Black screen after vm start

[luka-nedeljkov]

After I start the vm, my screen goes black, and Windows doesn't come on. I checked the logs for the vm and all it says is failed to allocate memory on repeat. If there are any more pictures of dumps/logs i could provide, please tell me. This worked this morning, then I came home, and it didn't. I even did a fresh arch install, and still the same outcome and errors

[QaidVoid]

Can you provide the complete log?

[luka-nedeljkov]

Can you provide the complete log?

win10.log?

[QaidVoid]

yeah

I had to force shutdown my pc with the power button because reboot or poweroff didn't work over SSH. Also, black screen.

The VM supposedly didn't crash. It only terminated when "reboot" was initiated. I suspect the VM might be working, but was unable to display (!!).

Can you provide your VM config (XML)?
