( https://gerrit.ovirt.org/79643 ) Change subject: engine: handle NPE for guest info data of a powered-off vm ...................................................................... engine: handle NPE for guest info data of a powered-off vm In case of powering-off a running VM with guest info data (i.e. guest agent installed) and guestOsType == OsType.Windows, then displaying 'guest info' sub-tab raises a NPE. This is becuase powering off a VM, sets vm.guestOs field to null in ResourceManager.resetVmAttributes(), while other Os fields like guestOsType are not set to null. That causes VmGuestInfoModel.setGuestOsNamedVersion() to fail while trying to access that field. This patch fixes it by avoid setting vm.guestOs to null.
