Hi Dave, vmctl pause and unpause worked! The guest is back to normal now. Thank you! I will also test Arnaud's /etc/ntpd.conf workaround: sensor vmmci0 refid LOCL stratum 8 trusted Also, do you believe that this impacts both 7.8 and 7.9 hosts? And possibly AMD only? It's interesting that I haven't seen it impact Debian guests at all, from Intel or AMD. I also have a suspicion (with way fewer datapoints) that it's only impacted OpenBSD guests where I've been using my own ntp server, which I found out recently is out of sync by a few minutes. My ntp configuration has looked like this on those guests (and the hosts, themselves:) server 2602:f5ef::1:0 sensor * (It's possible that isn't a great configuration to begin with.) Now I do have guests on Intel with the same NTP configuration as well. > diffstat refs/heads/master refs/heads/vmm-intr > M sys/arch/amd64/amd64/vmm_machdep.c | 76+ 32- > M sys/arch/amd64/include/vmmvar.h | 1+ 1- > > 2 files changed, 77 insertions(+), 33 deletions(-) Do you want me to test that patch? I might be able to put that on a 7.9 host that doesn't have any guests yet. I can also wait for it to be pushed out as a reliability fix and deploy it that way -- either is fine. Thank you, Slow Servers PS: Doing the pause/unpause triggered a bug that I haven't seen before. vmctl pause and unpause worked, but the command "hung" until I killed it with ctrl+c. /var/log/daemon: Aug 29 15:35:37 odin vmd[61999]: potato: paused vm 6 successfully Aug 29 15:35:37 odin vmd[41111]: control_dispatch_vmd: lost control connection: fd -1 Aug 29 15:36:21 odin vmd[61999]: potato: unpaused vm 6 successfully.
