Subject Re: 答复: CloudStack 4.11.2 Snapshot Revert fail
Date Wed, 23 Jan 2019 09:54:07 GMT
Hi

I have just reproduced your issue (7.1 though, no updates, and not relevant
I guess...)
I changed VM (edit VM, while stopped) after it was previously snapshoot-ed
successfully

OS types vs restore results below:
Centos 6.6 x64 fails to restore,
CentOS 6.7 x64 fails to restore
CentOS 6.5 x64 CAN restore just fine !
CentOS 7.x x64 fails to restore

I also could NOT make a VM snapshot while VM was set (OS Type) as CentOS
7.0 (6.6x64 also, etc) with "Unexpected exception" message in mgmt logs.

Please file a bug here https://github.com/apache/cloudstack/issues and
hopefully someone will  pick it up in some of next releases.
Please also do a little bit of more testing, to see what works, what not,
so you can "properly" file a bug.

Thx
