Yesterday I was validating pve 3.1. I rebooted one of my KVM guests
which is configured to use kexec. This resulted in a kernel crash on the
pve host at the time the kernel was supposed to be started. A call trace
was displayed on the screen of the host and I had to force reset it.
I've since been trying to reproduce but currently I'm unable to.
What I can say however is that loading the new kernel does not work at
all actually. I just see "Starting new kernel", and the machine hangs
indefinitely. I'm not sure if this is related to kvm or there's an issue
on my machine though.
