Hi,
I have a linux guest running in qemu-kvm which freezes temporarily whenever the
host clock is advanced. The freezing is ~1s/month of advance. So advancing
the host clock by 1 year the guest will be frozen for about 12 seconds. There
appears to be no impact when the clock is wound back however.
The guest is using kvm-clock source if that matters.
#uname -a
Linux NO-HOSTNAME 2.6.32.59.cge #1 SMP PREEMPT Tue Jan 28 14:38:11 PST 2014
x86_64 GNU/Linux
Also during the freeze it also appears that some signals may be lost. For
example, the acpid failed to respond to the system_powerdown command in the
qemu shell.
I know this is an unusual scenario but one for which I would like an
explanation.
Has anyone else experienced this behaviour or can explain what may be going on
here?
James
