[Bug 1292234] Re: qcow2 image corruption in trusty (qemu 1.7 and 2.0 candidate)

[Serge Hallyn]

Hi Jamie,

just to make sure, did you permanently disable ksm?  Does

cat /sys/kernel/mm/ksm/run

still show 0?

I've so far never seen a case where a reboot did not fix the issue,
nor have I seen an issue (other than suspending the host sometimes
causing the VM to hang so that I have to destroy it) with ksm
disabled.

I had hoped to do some large parallel upgrade tests this week, but
network at linuxcon is not up to the task (even with apt-cacher-ng!)
If I can find a better room I'll see about trying there.
