[fedora-virt] Fedora 14 KVM - all SMP 2.6.35.x guests are hanging

[Richard Chan]

Unfortunately all other clock sources don't work either.
The boot process reaches different stages but still gets stuck.

I reverted to a 2.6.32.x guest and that booted successfully to SMP /
desktop.

It seems to be a problem with 2.6.35.x kernels.
