A major problem (and after the netdiff fix, the only one that comes to mind in FreeBSD/Xen, from a SA PoV) right now is the VMs losing massive amounts of time (just the other day I manually ran ntpdate, for a 1h adjustment); started a thread last week or so, but it died down. It may not happen 100% of the time (calcru: runtime went backwards + losing system time), as I remember that a couple of years ago several people on the list had this problem while I wasn't experiencing it. Perhaps it depends on the dom0 OS, some system hardware.. I really have no idea.. If someone else is running amd64 HVM+PV, let us know if you see the same? Regards, Hugo
