My mistake correct version of vdsm where it happen: vdsm-4.17.12-1.el7ev.noarch POWER doesn't have a concept of CPU host passthrough really. The checkbox should probably be disabled. Decreasing Severity since this is not supposed to work This bug was accidentally moved from POST to MODIFIED via an error in automation, please see mmccune with any questions Looks like referenced pathces are not in 3.6.6 rc2 code, can you check if this has to be moved to QE or to POST? Ported to 3.6.6 branch. Is this included in the 3.6.6 build? If so, please move to QE, otherwise re-target to 3.6.7. Checked on rhevm-3.6.6.2-0.1.el6.noarch Bug still exist I can see that bug solved under rhevm-3.6.7-0.1.el6.noarch, so you can move it ON_QA and I will Verify it Verified on rhevm-3.6.7-0.1.el6.noarch |
Created attachment 1105288 [details] vdsm log Description of problem: Start vm with "Pass-Through Host CPU" enabled failed with traceback under vdsm log: Thread-22434::ERROR::2015-12-13 05:03:58,956::vm::758::virt.vm::(_startUnderlyingVm) vmId=`3f3cd31f-b2de-4341-b36b-6b63898935f0`::The vm start process failed Traceback (most recent call last): File "/usr/share/vdsm/virt/vm.py", line 702, in _startUnderlyingVm self._run() File "/usr/share/vdsm/virt/vm.py", line 1889, in _run self._connection.createXML(domxml, flags), File "/usr/lib/python2.7/site-packages/vdsm/libvirtconnection.py", line 124, in wrapper ret = f(*args, **kwargs) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 3611, in createXML if ret is None:raise libvirtError('virDomainCreateXML() failed', conn=self) libvirtError: internal error: Unknown CPU model hostPassthrough Version-Release number of selected component (if applicable): vdsm-4.17.13-1.el7ev.noarch How reproducible: Always Steps to Reproduce: 1. Create vm and pin it to host 2. Enable "Pass-Through Host CPU" option on vm 3. Start vm Actual results: vm failed to start with above error Expected results: vm succeed to start and inherit cpu flags from host cpu Additional info: looks like instead of mode we send hostPassthrough to cpu model <cpu> <model>hostPassthrough</model> <topology cores="1" sockets="1" threads="1"/> </cpu>
