@serge-hallyn:

First step is to debug this issue and see if its a reasonable fix. If
that's possible then we should leave qemu alone.

Second if we want to disable KSM for nested VMs relying on a 'QEMU' cpu isn't sufficient if someone uses a different -cpu flag. We could do:
grep -q "Booting paravirtualized kernel on KVM"  /var/log/kern.log && echo 0 > /sys/kernel/mm/ksm/run
Or use tools like virt-what.

Regardless I'll work on step 1.
