Try booting the guest with clocksource=acpi_pm on the kernel command

https://bugzilla.redhat.com/475598
It's an issue with KVM's paravirt clock. We have a workaround in the
rawhide host kernel which disables kvmclock support on affected hosts. A
real fix is in progress upstream.
The F-10 branch has the workaround, but only for the 2.6.29 builds. I
don't think we have it in the 2.6.27 updates (i.e. the
private-fedora-10-2_6_27 branch).
Chuck, could we get linux-2.6-kvmclock-unsync-tsc-workaround.patch
pulled into F-10?
I'm fully virtualised. I think. What's this about a paravirt clock in KVM?
fwiw my guest is Debian, with a 2.6.18 kernel.

I'm running virtualbox on a new HPDC5850 (AMD 4540B cpu, AMD chipset),
Windows Server 2003, and on an Apple Leopard-based intellish laptop.
hdparm -t /dev/sda
checks out quite a bit faster on the laptop, both with Debian guests.
