xbzrle relies on reading pages that have already been sent to the destination and then applying the modifications; we can't do that in postcopy because the destination may well have modified the page already or the page has been discarded. I already didn't allow reception of xbzrle pages, but I forgot to add the test to stop them being sent. Enabling both xbzrle and postcopy can make some sense; if you think that your migration might finish if you have xbzrle, then when it doesn't complete you flick over to postcopy and stop xbzrle'ing. This corresponds to RH bug: https://bugzilla.redhat.com/show_bug.cgi?id=1368422 Symptom is: Unknown combination of migration flags: 0x60 (postcopy mode) (either 0x60 or 0x40) Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Reviewed-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Juan Quintela <quintela@redhat.com> |
