[ovirt-users] VM is locked, servlet , and SpiceVersion.txt problem

[Terry hey]

Hello everyone!
Thank for your time to analyize my problem. Totally, i have two question.
I encountered vm image lock problem. The following action is what i have to
and make the vm image locked.
First, i imported a vm. Since it is take too long time to import and the
engine.log always repeatly said it was waiting child command id.
"2018-02-23 16:37:46,603+08 INFO
 [org.ovirt.engine.core.bll.ConcurrentChildCommandsExecutionCallback]
(EE-ManagedThreadFactory-engineScheduled-Thread-16)
[1c44d543-4dcc-429d-a172-386cc860afe0] Command 'ImportVm' (id:
'09718bd2-797d-4323-b1ad-1a85604543c3') waiting on child command id:
'9e285b2d-c0c7-4a75-8c70-b619b45c6855' type:'CopyImageGroup' to complete
"
So,I thought the operation was not normal. So,
1. I use "./unlock_entity.sh" to unlock the virtual disk of the vm.
2. Virtual disk was unlocked but vm was still locked. Therefore, i use
"./unlock_entity.sh" to show locked vm. But there was nothing.
3. Then i used "./taskcleaner.sh" to clean all task. But nothing happen.

Q1: So, now, i would like to ask how to unlock the vm image so that i can
delete or use it.

Q2: In addition, there are two error or warning appeared in engine.log
1. 2018-02-23 09:57:19,495+08 WARN

Do you guys have any idea what do they mean?

I really appreciate you help. Thank you!

Regards
Terry
