the guest boot console about "clocksource tsc unstable" and some kernel
oops. Once it got far enough to start network I logged in and checked
the clocksource and it currently is 'acpi_pm' even though the kernel
line says clocksource=pit. The available clocksources are acpi_pm,
jiffies, and tsc. I do not see 'pit' in the list. How do I fix this issue?

If the guest runs 'extrememly' slowly then the most like thing is that
it has fallen back to using QEMU emulation, instead of KVM hardware
acceleration. Check the /var/log/libvirt/qemu/$GUEST.log to see if there
is any mesage about not being able to open /dev/kvm. Also make sure that
KVM modules are loaded, and that 'virsh capabilities' lists KVM as a valid
domain.

<tt>Ok, I checked the guest log and it says:<br>
/dev/kvm: no such file or directory.<br>
<br>
So how do I make this node? Shouldn't libvirt have made it for us?<br>
