Hi again, It seems it was too rush to say goodby :-). Everything was ok while resetting all the networks and stuff in the 3.2 environment until it came the time to create the VMs. I have an ISCSI target with different luns for each VM and when I created one of them and tried to start it, it failed with this error: vdsm.log from one of the hosts: Thread-8267::ERROR::2013-07-01 14:53:58,697::vm::716::vm.Vm::(_startUnderlyingVm) vmId=`1084e767-1b5e-4903-af0f-c7d90528725b`::The vm start process failed Traceback (most recent call last): File "/usr/share/vdsm/vm.py", line 678, in _startUnderlyingVm self._run() File "/usr/share/vdsm/libvirtvm.py", line 1546, in _run self._connection.createXML(domxml, flags), File "/usr/lib64/python2.6/site-packages/vdsm/libvirtconnection.py", line 111, in wrapper ret = f(*args, **kwargs) File "/usr/lib64/python2.6/site-packages/libvirt.py", line 2645, in createXML if ret is None:raise libvirtError('virDomainCreateXML() failed', conn=self) libvirtError: internal error process exited while connecting to monitor: Supported machines are: pc RHEL 6.4.0 PC (alias of rhel6.4.0) rhel6.4.0 RHEL 6.4.0 PC (default) rhel6.3.0 RHEL 6.3.0 PC rhel6.2.0 RHEL 6.2.0 PC rhel6.1.0 RHEL 6.1.0 PC rhel6.0.0 RHEL 6.0.0 PC rhel5.5.0 RHEL 5.5.0 PC rhel5.4.4 RHEL 5.4.4 PC rhel5.4.0 RHEL 5.4.0 PC engine.log 2013-07-01 14:53:57,503 INFO [org.ovirt.engine.core.bll.RunVmCommand] (pool-3-thread-47) [5b2421ce] Running command: RunVmCommand internal: false.
