So I'm ssh'ed into my kerberos kdc server and at the same time I'm playing with nfsv4 and I clearly push the boundary somewhere and my NFS server has a kernel BUG and goes wibbly... ctrl-alt-sysreq S-U-B wibbly...
Now the kerberos kdc is a VM on the nfs server; which also holds the home directory for my desktop. So my desktop hangs hard.... toast.
I wander over to the nfs server and shut it down as best I can and reboot it.
It comes back... and as it does my desktop wanders into life, my ssh session to the VM is still active; nothing happened.
I like crashes like that :)
