Looks like upstart doesn't work quite like I thought. Running this
from the command line shows it changed the file path:
KRB5_KTNAME=/etc/libvirt/krb5.keytab strace -f -ff -eopen libvirtd
--listen 2>&1 |grep keytab
[pid  2412] open("/etc/libvirt/krb5.keytab", O_RDONLY) = 39

Yeah, I ran into that one way too many times to forget :(
hostname -f gives fqdn, dig on that fqdn gives the right IP, dig -x on
that IP gives a PTR to the same fqdn.
