Assuming this is the same patch that I posted on the list after someone sent it to me, it seems to solve the problem (xn* works). It is similar, but not identical. If you have the resources to test my patch, I would appreciate it. 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? We run it at Spectra Logic. I can replicate the "calcru: runtime went backwards" issue if I do not pin our FreeBSD VM such that it exclusively owns the CPUs it uses. I have not had time to dig into this yet, since it is not a blocking bug for our product. I hope to have some time to work on this in a few weeks. -- Justin ___ freebsd-xen@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to "freebsd-xen-unsubscr...@freebsd.org"

I have several VMs running with it for around 3 weeks now, no problem whatsoever in that area. > Excellent! I was already assuming that 9.0 is going to be as broken > with Xen as 8.2.
