XenServer 6.5 SP1 with almost all patches (3 hosts in pool), FreeBSD 11.0-R= ELEASE-p2, xe-guest-utilities-6.2.0_2 installed via pkg. First migration from host 3 to host 1 is ok. Some seconds later I start a new migration from host 1 to host 2 and when m= igration finishes (as seen in XenCenter) then the VM switches to the VGABio= s screen ("Plex86/Bochs VGABios (PCI) current-cvs 01 Sep 2016 ... cirrus-co= mpatible VGA is detected"). The VM seem to hang and does not respond. In Xe= nCenter I see that all the CPU's of the VM go up to 100 percent. Then after 17 minutes the VGABios screen disappears and I see the console, = the CPU usage as seen in XenCenter goes down. I logged in as root before I = started the first migration and root is still logged in. So it was a hang a= nd not a reboot. 20 minutes later I start a new migration from host 2 to host 3 and the prob= lem occurs again. This problem does not exist with 10.3-RELEASE on the same hosts. > -----Original Message----- > From: owner-freebsd-xen@freebsd.org [mailto:owner-freebsd-xen@freebsd.org= ] > On Behalf Of Jay West > Sent: Wednesday, December 07, 2016 6:26 PM > To: rainer@ultra-secure.de > Cc: freebsd-xen@freebsd.org; owner-freebsd-xen@freebsd.org > Subject: RE: 11-RELEASE and live migration >=20 > Rainer wrote... > ------ > We've also seen this (unexplainable reboots, I think they happen after > migrations). >=20 > But it never hangs.
