<br>
we are experiencing trouble when using OpenNebula with KVM, LVM on CentOS.<br>
<br>
We've tried using virtio and ide, with and without caching - the problem remains.<br>
<br>
The VM mounts its filesystem readonly and logs "journal I/O commit error", on the host system we get "end_request: I/O error, dev vda, sector" errors.<br>
<br>
Has some experienced similar problems?<br>
<br>
Cheers,<br>
Yves<br>
