Can't start cloned VM after installing LG

Hi,

I hope it’s ok to ask for help even though i’m not super technical. Pretty much a script kiddie, but not a kid.

Everything is running fine on a VM i installed Windows 10 Pro on with latest LG. Ubuntu 22.04 is the host.

When I clone that machine I get a blank screen when I start it. I kept a copy of a VM with no LG and just GPU passthrough and it clones and starts fine.

Here is the terminal print out from the host when I try to connect to the LG VM clone.

I can’t get to the LG host/Windows guest to get anything to provide you with. If someone could point me in the right direction to provide anything else that could be useful.

Should I try an earlier version of LG?

thankyou,
Frink

Since you have another VM, is this correct?

QEMU xml, and the LG host app log.
