The execution state of the host of system operatio is monitored as a task, can periodically obtain the execution shape of every task
State, that is, judge whether the host in the task is completed reboot operation.
In this application example, it is specific under preset store path according to being viewed locally that whether host, which completes reboot operation,
File whether there is to realize.
In step 2), since it is desired that identifying whether the host needs to restart, spy is newly had under specific store path
Fixed file；Once the host completes reboot operation, the file under the store path will be deleted, on the contrary, if the host
Reboot operation is not yet completed, then the file under the store path will then exist.That is, if risen in escalation process
Grade packet requires host to restart, and can create a logo file, once host, which executes, completes reboot operation, then deletes this document.Cause
This, judge host whether restart it is out-of-date, by judging whether this document is not present, if state from exist become being not present,
It then indicates the host after upgrading, is rebooted.
5) preparation operation is that its corresponding eligible task is obtained from current upgrading task before restoring upgrading after host is restarted,
By way of iterative processing, one by one by the corresponding corresponding entity of eligible task return back to upgrading before from the above, it can be seen that, this
The virtualization system that invention provides upgrades aft engine reboot process method, state, for example, exiting host maintenance mode or opening
The virtual electromechanical source closed before upgrading.
Application example provided by the invention prompts subscriber's main station needs to restart, task flow engine after the completion of system upgrade
Acquisition state is upgrading successfully for task, and judges whether its corresponding upgrade package needs to restart and whether host restarts into
Function, if it is judged that being very, then to prepare operation, system mode before recovery upgrades before rollback upgrading；It is automatic to restore before upgrading
Preparing operation, restores system mode before upgrading, automatic realize is restarted and is upgraded rollback, reduce manual operation, time cost is saved,
Improve product competitiveness.
