Each time I kill qemu-kvm I get this error:
KVM: injection failed, MSI lost (Operation not permitted)
Jan, any idea?

Race in shutting down resources?
What do you do precisely? I never saw this.

I boot guest like this:
/home/mst/qemu-test/bin/qemu-system-x86_64 -enable-kvm -cpu kvm64 -m
1G -drive file=/home/mst/rhel6-try.qcow2 -net
nic,model=virtio,netdev=foo -netdev id=bar -device e1000,netdev=bar
-redir tcp:8022::22 -netdev
tap,id=foo,ifname=msttap0,script=/home/mst/ifup,downscript=no,vhost=off
-vnc :1 -smp 16 -snapshot
At some later point I kill it from another shell:
kill `pgrep qemu`

Hmm, cannot reproduce, even under flood-ping load on the virtio device,
ie. the one that is using MSI. I'm afraid you will have to trace the
event flow.
