Re: Very slow clock in Debian vmm guest
Hi Jordan, Thanks for the link -- I have not tested it yet but I believe it will solve my issue. I did search the misc list but I did not see anything in the past year that seemed relevant to my particular time issue. --Aaron On Sat, 2020-08-29 at 01:17 -0700, Jordan Geoghegan wrote: > If you check the mailing list archives, you will see that this > issue has > been discussed extensively. > > Dave Voutila has written a linux vmm kernel driver to work > around some > of the issues: > > https://github.com/voutilad/virtio_vmmci > > Regards, > > Jordan > > On 2020-08-28 20:48, Aaron Miller wrote: > > I have a debian testing guest running in vmm(4) on my -current > > system, and the internal clock is very slow.

Re: Very slow clock in Debian vmm guest
If you check the mailing list archives, you will see that this issue has been discussed extensively. Dave Voutila has written a linux vmm kernel driver to work around some of the issues: https://github.com/voutilad/virtio_vmmci Regards, Jordan On 2020-08-28 20:48, Aaron Miller wrote: I have a debian testing guest running in vmm(4) on my -current system, and the internal clock is very slow.

Very slow clock in Debian vmm guest
I have a debian testing guest running in vmm(4) on my -current system, and the internal clock is very slow. For example running `sleep 3` takes about 10 seconds of real time to run. This is too much for ntpd to correct, unfortunately. Anyone know what the problem is and how I might go about fixing it?
