Description of problem: Migrating diskless VM without any OS causes the VM to get paused after several migrations. After that, even migrating diskfull machines causes them to get stopped. When trying to resume it, rhevm says it is running already. Stopping it works. Version-Release number of selected component (if applicable): libvirt-0.9.3-7.el6.x86_64 vdsm-4.9-84.el6.x86_64 How reproducible: 50% Steps to Reproduce: 1. Have a VM (diskless) on iSCSI 2. Migrate until it gets paused 3. Actual results: Paused VM. Expected results: VM migrated. Additional info:

From your logs: 11:11:14.229: 2791: debug : qemuMonitorEmitStop:896 : mon=0x7fbab40106d0 11:11:14.229: 2791: debug : qemuProcessHandleStop:374 : Transitioned guest masinka to paused state due to unknown event This means, qemu send us STOP event. Unfortunately, you didn't provide qemu logs which could have been a little more helpful here. However, if qemu stops a domain, there is not much libvirt can do.
Created attachment 523536 [details] qemu logs
From your recent attachment (nomadic_vm.log.dest): kvm: unhandled exit 80000021 kvm_run returned -22 I guess that's why qemu sent the STOP event. Anyway, if qemu decide to pause itself, i don't libvirt should resume it. Maybe this is not libvirt but qemu bug.
According to domain logs I believe this is a qemu issue. Therefore reassigning to qemu component.

Anyway, if qemu decide to pause > itself, i don't libvirt should resume it. Maybe this is not libvirt but qemu > bug. The above is a crash and not stop event. We need to have the host kernel logs too. It's unrelated to the stop event, there are just to many things together here. Can you see if live migration w/ disk do work?
Live migrations with disk works, but there are some problems as well sometimes (machine gets paused for example). Kernel logs follows. I'm not sure which host was src and which was a dest, but I can find it out if you'd like.

Can you try to reproduce but this time with "-cpu core2duo" ?

Can you attach qemu and the kernel logs please ?
Created attachment 529475 [details] qemu+messages logs The machine got paused after migration command issued at 12:21:00.
(In reply to comment #23) > Created attachment 529475 [details] > qemu+messages logs > > The machine got paused after migration command issued at 12:21:00. I see in the log that "-cpu Conroe" I asked to try and reproduce with "-cpu core2duo".
Any progress ?
- Should be closed with INSUFFICIENT_DATA (fixed). - I assume VirtQE tried to reproduce it as well?
Today reproduced. All required logs are attached.

This looks similar to this BZ: https://bugzilla.redhat.com/show_bug.cgi?id=756044
Can you see if the fix for 756044 fixes the issue ?
As it looks like the same behavior duplicating. *** This bug has been marked as a duplicate of bug 756044 ***
