Hello,
I'm running MATE 22.04 with 32GB ram with an NVIDIA graphics card. I use Virt-manager to run various machines.
The host and or guest machines crash intermittently. Usually the host or the guest will crash or just reboot.
I've seen two sets of errors, on the host machine and on the virtual machine.
On the host I've seen errors such as "Ubuntu has experienced an internal error" or "Virtual Machine Manager has stopped responding".
On the guest machine, also MATE 22.04(doesn't seem to matter what distro it is either), it will just freeze, sometimes its the host, sometimes its just the guest. I'm usually(mostly) using Firefox and Thunderbird. Nothing that I would consider very demanding especially on a machine with 32GBs of mem. When I run top, resources used are under 1%.
There is about a week, maybe two, where everything runs "tip-top" and is very smooth and a pleasure to use. Then I get an update that breaks something, not sure what, and the cycle starts all over again. Rather frustrating when trying to get something done.
I've been looking through the syslog in /var/log but haven't found a smoking gun so to speak. Is this the correct file to look in? Based on the errors I've received I suspect its Virtual Machine Manager but I don't like to assume. Is there a log I can post that someone can take a look at the next time it happens to at least get me looking in the right direction?
Appreciate any help!
