maybe it's a libvirt problem , since my nodes have used oVirt Node Hypervisor 2.2.2-2.2.fc16 engine: libvirt-0.9.11.4-3.fc17.x86_64 node: libvirt-0.9.6-4.fc16.x86_64 storage: No local fs, I have two Domain , one is using NFS fs, the other is GlusterFS mount by NFS. Both have the problem [root@ovirt-node-sun-1 ~]# strace -p 1209 -e chown -ff Process 1209 attached with 11 threads - interrupt to quit After start vm: [pid 1518] --- {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=19068, si_status=0, si_utime=1, si_stime=1} (Child exited) --- [pid 1518] --- {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=19069, si_status=0, si_utime=1, si_stime=1} (Child exited) --- [pid 1518] --- {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=19071, si_status=0, si_utime=1, si_stime=1} (Child exited) --- [pid 1518] --- {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=19072, si_status=0, si_utime=1, si_stime=1} (Child exited) --- [pid 1518] --- {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=19074, si_status=0, si_utime=1, si_stime=0} (Child exited) --- [pid 1209] --- {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=19080, si_status=0, si_utime=0, si_stime=0} (Child exited) --- [pid 1518] chown("/rhev/data-center/3bdc6f14-bb92-4b0e-8db2-d0ba4c34f61d/b5078b10-a044-42c5-b270-8b81cd51ce35/images/979c2849-2587-4015-bad5-53159a11b6ed/38648b73-b0d4-4f2a-9f46-5b20613abb7a", 107, 107) = 0 After stop vm: [pid 1209] chown("/rhev/data-center/3bdc6f14-bb92-4b0e-8db2-d0ba4c34f61d/b5078b10-a044-42c5-b270-8b81cd51ce35/images/979c2849-2587-4015-bad5-53159a11b6ed/38648b73-b0d4-4f2a-9f46-5b20613abb7a", 0, 0) = 0 On 26 Jul, 2012, at 3:48 AM, Dan Kenigsberg wrote:

Thanks, I just wanted to make sure it's not libvirt that does this.
Pardon me, I still suspect libvirt... Which version thereof do you have installed?
Which storage is used for the vm image - local fs, right?
would you strace -p `<libvirtpid>` -e chown -ff
and start another VM just to prove me wrong? You could do the same with <vdsmpid> to find the culprit.

Dear everyone:

then , i cannot start the vm , on the web logs event:
Just out of curiosity (it won't probably won't be the cause of the problem), do you have dynamic_ownership=0 in /etc/libvirt/qemu.conf ?
