--- Comment #2 from Dexuan Cui <de...@microsoft.com> --- The tsc-calibration fix was temporarily taken back last Friday because we found an interesting thing: with some kind of config, Xen can pretend to be Hyper-V by mimicking the hypervisor CPUID signature (this is usually to make Windows VM run better on Xen), but Xen doesn’t support Hyper-V timecounter, so the fix causes an unexpected panic when FreeBSD VM runs on Xen in this case. We're making another patch to better detect if the underlying hypervisor supports Hyper-V timecounter or not: https://lists.freebsd.org/pipermail/freebsd-current/2016-April/060519.html -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
