Virt-Manager keeps on locking up whenever VMs are launched

[Jonas Gamao]

Out of the blue, Virt-Manager would stop working, VMs get "paused" and after I kill the window, I can bring it back, but my VMs are not working anymore. I have to kill the VM and restart.

Seems to happen when I open the Viewer thingy. If I leave it closed it works fine.

[Jonas Gamao (yamiyukisenpai)]

In addition, when I say "open", I meant when I click the button "open". If I don't click it, but I start it, it works.

[Jonas Gamao (yamiyukisenpai)]

This applies to when I don't have a SPICE display (and using a GPU passthrough instead), and when I'm using a SPICE display.

If I have the configuration open, it doesn't crash.

[Jonas Gamao (yamiyukisenpai)]

I tried to launch a VM that's using SPICE display, and I got this:

It seems to be related to bug 1993751, since the last line are exactly the same.

[Jonas Gamao (yamiyukisenpai)]

Fixed it! Might've been a corrupted package as I reinstalled `cpp-12` and `g++-12` packages.

[Christian Ehrhardt  (paelzer)]

Hi Jonas,
I'm happy you resolved it for yourself, but I'm concerned as I fail to see the connection/influence of compilers (cpp-12/g++-12) onto prebuilt binaries from virt-manager.

If you ever find more about the root cause I'd be curious about it.

Otherwise - for now, since it is no more a bug, marking it "invalid".
