Change subject: core: prevent removing vm from export domain while it is being imported ...................................................................... core: prevent removing vm from export domain while it is being imported While VM is being imported from export domain, there was no kind of lock that prevented other commands from modifing the VM. So while the import operation was on progress, the user could remove the VM which is obviously something we need to prevent. This patch prevents the scenario above from happening by modify the ImportVmCommand to take shared lock on the VM at the export domain for the whole execution of the command, and modify the RemoveVmFromImportExportCommand to take exclusive lock on the VM which is about to be removed.
