[libvirt] sheepdog volume and number of copies
Hi libvirt devs!
Sheepdog have ability to specify number of copies (full replica or
erasure) for each vdi when it created,
Now xml looks like:
<volume>
<name>{VDI_NAME}</name>
<key>sheep/{VDI_NAME}</key>
<source></source>
<allocation unit="G">{VDI_SIZE}</allocation>
<capacity unit="G">{VDI_SIZE}</capacity>
<target>
<path>sheepdog:{VDI_NAME}</path>
<format type='unknown'/>
<permissions>
<mode>00</mode>
<owner>0</owner>
<group>0</group>
</permissions>
</target>
</volume>
in case of erasure we need to specify number of strips and number of
parity strips. In case of copies - number of copies. How the best
encode this in xml?
P.S. I van to create patch for libvirt to allow this, but stuck at xml
definition.
