We carry a patch for kexec(1) which does balloon up before doing the
actual kexec call. I propose to get such change into the upstream kexec
tools if that is indeed the way to go. The benefit is that the guest
waits until every ballooned page is populated. If the host is short on
memory then the guest will hang instead of crash after kexec.
