KVM guest sporadically fail to boot - no error messages

co flag

I've a KVM booting problem that appears different to the others I can find described online.

I have a guest that fails to boot every few days. No combination of destroy or restarting libvirtd services can make it boot, I have to reboot the entire host and then it's luck again as to whether the guest will boot.

I'd say roughly 75% of the time the guest boots successfully.

There're no obvious error logs that I've found. I looked in:

  • /var/log/libvirt/qemu/guest.log
  • /var/log/libvirt/
  • /var/log/syslog

I have tried connecting a console, but I never get anything:

$ virsh start --console guest
Domain guest started
Connected to domain guest
Escape character is ^]

Until I CTRL+5.

What's the best way of finding out what the issue is here?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
