Hello, My question from first look at is that, is it your environment? > Currently running SL 6.3, OpenStack Folsom packages from EPEL, Libvirt 0.9.10, > QEMU 1.2.1 built from an epel-testing SRPM for RBD support, and Ceph 0.54 If it's true, you have to upgrade SL and Ceph as much as you can. Because, as you might notice, there have been a bunch of bug fixes. And please attach logs related to Ceph, qemu and livbirt.
