Yes and no. It's both intentional and bug in our code. I was going to
suggest to use:
<domain>
...
<devices>
...
<disk>
...
<source>
<seclabel model='dac' relabel='no'/>
</source>
</disk>
</devices>
</domain>
But I've tried it out and found a bug [1]. After fixing it, I found out
that the DAC driver doesn't care about relabel='no' at all. So I've
posted second patch [2].
Moreover, I've got a patch set floating around that learns libvirt to
remember the original owner of chowned files [3].
