Similar to https://github.com/lago-project/lago/issues/32, have you checked if the issue is solved with the latest libvirtd version? (as the external bug you added suggests). If not, please comment on the above issue or open a new one. Cheers! |
Description of problem: When trying to initialize a Lago environment with more then one VM on EL7, Lago fails while running 'virt-sysprep' for some of the VMs while succeeding for others. Error message example follows: 2015-11-25 13:51:28,256 - root - DEBUG - command stderr: libvirt: XML-RPC error : Failed to connect socket to '/run/user/24044/libvirt/libvirt-sock': No such file or directory virt-sysprep: error: libguestfs error: could not connect to libvirt (URI = qemu:///session): Failed to connect socket to '/run/user/24044/libvirt/libvirt-sock': No such file or directory [code=38 domain=7] If reporting bugs, run virt-sysprep with debugging enabled and include the complete output: virt-sysprep -v -x [...] 2015-11-25 13:51:28,256 - root - ERROR - Error while running thread Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/lago/utils.py", line 44, in _ret_via_queue queue.put({'return': func()}) File "/usr/lib/python2.7/site-packages/lago/virt.py", line 123, in <lambda> utils.invoke_in_parallel(lambda vm: vm.bootstrap(), self._vms.values()) File "/usr/lib/python2.7/site-packages/lago/virt.py", line 909, in bootstrap ) for i, nic in enumerate(self._spec['nics']) if 'ip' in nic File "/usr/lib/python2.7/site-packages/lago/sysprep.py", line 122, in sysprep raise RuntimeError('Failed to bootstrap %s' % disk) RuntimeError: Failed to bootstrap /home/bkorren/src/workspace/jenkins/images/builder_root.qcow2 2015-11-25 13:51:28,266 - root - ERROR - Error occured, aborting Traceback (most recent call last): File "/usr/bin/lagocli", line 532, in main func(args) File "/usr/bin/lagocli", line 78, in do_init prefix.virt_conf(virt_conf, repo, store) File "/usr/lib/python2.7/site-packages/lago/__init__.py", line 349, in virt_conf env.bootstrap() File "/usr/lib/python2.7/site-packages/lago/virt.py", line 123, in bootstrap utils.invoke_in_parallel(lambda vm: vm.bootstrap(), self._vms.values()) File "/usr/lib/python2.7/site-packages/lago/utils.py", line 87, in invoke_in_parallel vt.join_all() File "/usr/lib/python2.7/site-packages/lago/utils.py", line 44, in _ret_via_queue queue.put({'return': func()}) File "/usr/lib/python2.7/site-packages/lago/virt.py", line 123, in <lambda> utils.invoke_in_parallel(lambda vm: vm.bootstrap(), self._vms.values()) File "/usr/lib/python2.7/site-packages/lago/virt.py", line 909, in bootstrap ) for i, nic in enumerate(self._spec['nics']) if 'ip' in nic File "/usr/lib/python2.7/site-packages/lago/sysprep.py", line 122, in sysprep raise RuntimeError('Failed to bootstrap %s' % disk) RuntimeError: Failed to bootstrap /home/bkorren/src/workspace/jenkins/images/builder_root.qcow2 Steps to Reproduce: 1. Create a Lago JSON file setting up more then one VM 2. run 'lagocli init' on EL7 with that JSON Actual results: Lago crashes with the error above and erases the prefix it began to create. Expected results: The Lago environment should be initialised. Additional info: Preventing Lago from bootstrapping VMs in parallel worked-around the issue. To do that the VirtEnv.bootstrap method was patched with the following code: def bootstrap(self): #utils.invoke_in_parallel(lambda vm: vm.bootstrap(), self._vms.values()) for vm in self._vms.values(): vm.bootstrap()
