I've been very careful to keep nested SVM safe, but I've not got a good
test for that. Is there any test suite for the nested case?
To test this you can boot a nested Linux guest and let both, L1 and L2
guest use kvm_clock. Then put some load into the L2 guest and see if the
L2 or the L1 freezes hard (which happens with kvm_clock when the TSC
went backwards for one of them).
With recent guests, they won't freeze any more, since we detect the tsc
going backwards and compensate (in a brute-force way, nothing clever).
But you can printk the maximum compensation and see if it's something
unreasonable.
