You only need to quiesce if you have guest-visible data-structures

quiesce, but I don't know of any other VMM that would.
VMI, KVM and lhype should be capable of transparent migration without
guest involvement.
Sure; Xen makes the explicit design decision that suspend/resume/migrate
are things that the guest is likely to want to have some involvement in
if its already doing all the paravirt games. A
semi-kinda-paravirtualized hvm Xen guest doesn't have to worry too much
about those kinds of things.
