Hi ALL<br><br>After upgrade to libvirt-0.9.11.3-1 I'v got an unstable work of engine. Engine began to lost connection with VM's. VMs worked correctly, but their status in engine were "not responding", migration didn't work also. After downgrade to libvirt-0.9.11-1 engine began to work correctly. Hosts are fedora16 with 3.3.4-1 kernel, qemu-kvm-0.15.1-4. I tested libvirt-0.9.11.3-1 on different builds of vdsm/engine<br><br>In engine.log there are many such errors despite of libvirt version<br><br>2012-05-06 03:53:29,212 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-67) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:53:33,242 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-95) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:53:33,242 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-73) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:53:53,437 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-18) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:53:53,437 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-44) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:53:57,489 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-71) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:53:57,489 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-38) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:54:01,519 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-37) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:54:01,519 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-46) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:54:09,606 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-65) Failed to decryptData must start with zero<br>2012-05-06 03:54:09,606 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-76) Failed to decryptData must start with zero<br>2012-05-06 03:54:11,619 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-80) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:54:11,619 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-70) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:54:13,632 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-69) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:54:13,632 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-87) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:54:17,687 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-73) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:54:17,687 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-95) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:54:19,698 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-11) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:54:19,698 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-66) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:54:21,713 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-86) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:54:21,713 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (QuartzScheduler_Worker-92) Failed to decryptData must not be longer than 128 bytes<br>2012-05-06 03:54:31,810 ERROR [org.ovirt.engine.core.engineencry<br><br>&nbsp;<br><br><br>--<br><br>
