We will need some more logs, please let me ask for: "hard crash on the host" is the host kernel crashing and the whole system goes down? - If yes, then is there a way to get the log that contains the kernel crash? - If no then I'd assume you mean that the associated qemu process dies right (more likely)? In that case please provide: a) /var/log/libvirt/qemu/<guestname>.log b) if you get a crash in /var/crash/ of the qemu process either direct or via apport [1]
To silence apparmor in this you might consider removing the second disk "/home/brian/.seconddrive/windowsVM.img" from the guest definition just to see if it has any effect to the issue. Given the issue it is unlikely to find something interesting in libvirt's log, but since I need to reach out to you for logs anyway let us be complete. No need to enable extra debugging output, but a snippet of `journalctl -u libvirtd` from when the guest was started until it crashed woulc be nice as well. How is your guest definition looking, since you assume it is network related which network definition do you use - best would be to attach the full output of `virsh dumpxml <guestname>` here at the bug as it would help to reproduce the issue. Finally how did you setup networking in the guest, any special drivers for virtio installed? Or just windows as-is, if so which windows version btw? I have no other windows than Win98 around and that doesn't fail :-) I'm asking around for one. But there would be one more great thing, if you could test that it triggers on a fresh install from an ISO [2] as well then everyone even without a license could give it a debug try. So if you - knowing to be affected - could check and confirm that it would be great.
