Hi, I recently re-installed my test oVirt environment, upgrading from 3.5.2 to 3.6.0 beta 3 (Engine 3.6.0-0.0.master.20150819134454.gite6b79a7.el7.centos, VDSM 4.17.3-0.el7.centos, GlusterFS 3.7.3-1.el7) in the process. Due to a software issue outside of oVirt I had to start with a clean install for 3.6, however I kept all the old storage domains. All hosts and the engine are running CentOS 7.1 and I'm using hosted-engine.
During the setup/recovery process I encountered the following issues: :: Could not create GlusterFS Data domain due to 'General Exception' I attempted to create a Data domain using a FQDN associated with a floating IP, so that hosts could still mount the domain when the specific GlusterFS host used to define the storage was down. This FQDN was resolvable and contactable on each host in the farm. The floating IP is shared between two of the four GlusterFS hosts. The logs reported an unhandled exception ('x not in list') raised by the below statement (line 340 in https://github.com/oVirt/vdsm/blob/master/vdsm/storage/storageServer.py ): def _get_backup_servers_option(self): servers = [brick.split(":") for brick in self.volinfo['bricks']] servers.remove(self._volfileserver) #<--- Exception thrown here if not servers: return "" return "backup-volfile-servers=" + ":".join(servers) My assumption (without looking too deep in the code) was that since I used a FQDN that did not have any bricks associated with it, 'self._volfileserver' would be set to a name that would not appear in 'servers', resulting in the exception. I patched it as per the following: def _get_backup_servers_option(self): servers = [brick.split(":") for brick in self.volinfo['bricks']] if self._volfileserver in servers: self.log.warn("Removing current volfileserver %s..." % self._volfileserver) servers.remove(self._volfileserver) else: self.log.warn("Current volfileserver not in servers.") if not servers: return "" return "backup-volfile-servers=" + ":".join(servers) Once patched the Data domain created successfully and appears to be working normally, although I'm not sure if the above change has any negative knock-on effects throughout the code or in specific situations. I'd suggest that the _get_backup_servers_option method be tweaked to handle this configuration gracefully by someone with more knowledge of the code, either by allowing the configuration or rejecting it with a suitable error message if the configuration is intended to be unsupported. :: Could not import VMs from old Data domain due to unsupported video type (VGA) Once the new data center was up and running, I attached the old Data domain and attempted to import the VMs/templates. Template import worked fine, however VM import failed with an error stating the video device (which came up as VGA) was not supported. I attempted to fix this by specifically defining the video type as 'qxl' in the .ovf file for the VM in the OVF_STORE for the old storage however the VM would always come up with video type VGA in the import dialog, and the import dialog does not permit the value to be changed. The workaround was to add 'vnc/vga' to the supported protocols list in a .properties file in the engine OSinfo folder, e.g.: os.other.devices.display.protocols.value = spice/qxl,vnc/cirrus,vnc/qxl,vnc/vga Once the engine was restarted the VM import process worked fine, and there have been no issues starting the VM with a VGA device or accessing the VM's console. To resolve the issue I'd suggest that either: - 'vnc/vga' be added to the default supported protocols list; or - the video type defined in the .ovf file for the VM to be imported is recognized/honoured by the import dialog; or - if the import dialog defaults to a particular video device, that it default to one that is supported by the engine for the OS defined in the VM's .ovf file. I can create Bugzilla entries for the above if required. Cheers, Chris PLEASE CONSIDER THE ENVIRONMENT, DON'T PRINT THIS EMAIL UNLESS YOU REALLY NEED TO.
