Christian replied... I changed the timecounter from XENTIMER to ACPI-fast and then I did about 10 migrations between our 3 hosts. I always started the next migration a few seconds after the previous migration finished. The VM didn't stuck now and I didn't see the VGABios screen on the console. I can also add to this... changing timecounter to ACPI-fast definitely fixes the problem. I can migrate a handful of freebsd11 vm's back and forth and all stay running correctly. So... bug in XENTIMER? _______________________________________________ firstname.lastname@example.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to "freebsd-xen-unsubscr...@freebsd.org"
