Subject RE: Strange size of template from snapshot on XenServer

very well

Subject: Re: Strange size of template from snapshot on XenServer

Anshul, I tried with ACS 4.5.2 where commit “8a3fd10” is not present. This is the commit
where Daan and I removed some code that seemed (is? at least for me) logicless (https://github.com/apache/cloudstack/pull/1124
and https://github.com/apache/cloudstack/pull/1056).

I tested with ACS 4.5.2, which I have in a test environment. I have ACS 4.5.2, NFS as the
primary storage, and XenServer 6.5 as hosts. I managed to reproduce the problem as Lotic is
having.

I spin up a VM, then I created a file of 2GB in this VM, and later I took a snapshot of the
root volume of it (the VM only has the root volume). The VHD “687f86f2-1aee-4e90-a64a-3b3c28376fcd.vhd”
is the first snapshot of the root volume. If I create a template from this snapshot, everything
works. I created a new VM from the template of the first snapshot, and it worked, and the
2GB file was there. Then, I returned for the first VM (from which I took the snapshot), I
created another 1GB file. Then I stopped the VM again and took the second snapshot (27d37d21-13a6-488d-b2f0-0ac54236b83a.vhd).
The interesting thing here is that the file size reduced!? And I also noticed that there is
no hierarchy in the VHDs files. I tried to start a VM from a template that I created with
the second snapshot, and it did not work as the problem Lotic is having.

Was it not working way before “8a3fd10”?! I think we will need help from more folks here
to see if this is a problem that only affects XenServer deployments. I will also test on my
4.9.2.0 environment again to see if I miss anything.
