Re: Problem with CLOUDSTACK-10240 (Cannot migrate local volume to shared storage)


Hey Mike, I got the branch 4.11 to start fixing the problem we discussed,
but I do not think my commit was backported to 4.11. I mean, I am at
"VirtualMachineManagerImpl" and the code is not here. I also checked the
commit (
https://github.com/apache/cloudstack/commit/f2efbcececb3cfb06a51e5d3a2e77417c19c667f)
that introduced those changes to master, and according to Github, it is
only in the master branch, and not in 4.11.

I checked the "VirtualMachineManagerImpl" class at the Apache CloudStack
remote repository in the 4.11 branch, and as you can see, the code there is
the “old”   one.
https://github.com/apache/cloudstack/blob/4.11/engine/orchestration/src/com/cloud/vm/VirtualMachineManagerImpl.java

I got a little confused now. Did you detect the problem in 4.11 or in
master?
