Using libvirt under openstack I encounter a problem when launching a VM with multiple partitions (2 G image) , While a single partition can be launched successfully . The launch is done with Openstack. We are using in libvirtd.conf log_level=1 and log_outputs="1:file:/var/log/libvirt/libvirtd.log" we can see that in /var/log/libvirt/libvirtd.log appear the following error message and the VM is finally shutdown :
Do you have some filters applied? If not, the file should have more messages. Actually, it should get so big it is unsuitable for the list :)

This means qemu died before we even connected to the monitor socket. And as can be seen from the instance log there is no output from qemu as to why it died. If you properly turn on debug logs (and restart libvirtd) you should be able to see at least whether it was libvirt who killed the qemu process (and in that case you should also see why it got killed). If that's not the case, though, I can't tell why qemu does not start. But I can recommend few things to try: 1) start qemu using the command line from the logs, but beware it needs to be modified (remove the '-S' and don't use any file descriptors when launching it) 2) try reproducing this with current upstream libvirt and see whether the problem is still there 3) debug the qemu process and see why it dies Sorry I have no specific info that would help right away.
