[Qemu-devel] qemu throws KVM internal error - Any ideas?

[Lucas Meneghel Rodrigues]

Hey Gleb, Marcelo:

I was looking at the sanity jobs for qemu.git and found this error that 
happened during RHEL 6.3 guest reboot test:

I'm not sure this is reproducible (1st time I've seen this), I thought 
it'd be good to report it here though. We also seen the sieve unittest 
failure that I have already reported a couple of days ago.

Cheers,

Lucas
