[Xen-devel] Time Change Issue Xen 4.1
Hi all,
Already posted this over in xen-users and Konrad confirms it as a
bug and suggested to repost
it over here!
Issue is that changing the time in dom0 doesn't take effect on the
VMs until a reboot of dom0.
The testing example below illustrates what I mean....
Synopsis of testing:
Booted the physical machine, date tells me it's 17:15:45. Hwclock
agrees.
Booted a VM (using xl as xm seems to be labouring under the
impression that blockdev is missing - it isn't)
The login prompt displays the time as 17:17, which is the expected
behaviour.
Changed the time in dom0 - (date +%T -s 12:00:00), synced to
hwclock.
Check that date and hwclock match - they do.
Destroy the VM and recreate.
The login prompt displays the time as 17:22. Unexpected!
Kernel: I git cloned tag v3.1 from the kernel.org linux.git, and
applied xen-settime patches
Also tested with jeremy-git-xen-next-2.6.32 (.41/.46) without patch,
they wouldn't apply.
Xen: 4.1.1/4.1.2
Distribution: Gentoo
It still doesn't work.
I've tested that the issue also exists in Debian Squeeze (with
linux-image-3.0.0 from testing as 2.6.32-5 is broken
on my hardware).
