Since we use the cluster name for the SSH known_hosts file, ssh will
always detect a changed IP (since we never connect to the cluster master
name, but the node names), and will complain about it/try to update the
user known hosts file (since that is /dev/null, it doesn't matter, but
it's not nice). So we disable the IP check.

boot=on implies that KVM boots using extboot. This is only required
to boot non-IDE disks and has the side-effect that there is at most
one bootable device. This behaviour breaks some operating systems,
most notably the windows installer that tries to chainload the hard-disk
from the CD-ROM after the initial part of the installation.

Currently some hypervisors (namely kvm) need to do some cleanup after
making sure an instance is stopped. With the moving of the retry cycle
in backend those cleanups were never done. In order to solve this we add
a new optional hypervisor function, CleanupInstance, which gets called
at the end of the shutdown procedure, and which interested hypervisors
can implement to be sure not to miss cleanup operations.

that live instances on that node keep working, and that cluster verify
