This patch converts NUMA configurations between the Xen libxl
configuration file format and libvirt's XML format.
XML HVM domain on a 4 node (2 cores/socket) configuration:
<cpu>
<numa>
<cell id='0' cpus='0-1' memory='2097152' unit='KiB'>
<distances>
<sibling id='0' value='10'/>
<sibling id='1' value='21'/>
<sibling id='2' value='31'/>
<sibling id='3' value='21'/>
</distances>
</cell>
<cell id='1' cpus='2-3' memory='2097152' unit='KiB'>
<distances>
<sibling id='0' value='21'/>
<sibling id='1' value='10'/>
<sibling id='2' value='21'/>
<sibling id='3' value='31'/>
</distances>
</cell>
<cell id='2' cpus='3-4' memory='2097152' unit='KiB'>
<distances>
<sibling id='0' value='31'/>
<sibling id='1' value='21'/>
<sibling id='2' value='10'/>
<sibling id='3' value='21'/>
</distances>
</cell>
<cell id='3' cpus='5-6' memory='2097152' unit='KiB'>
<distances>
<sibling id='0' value='21'/>
<sibling id='1' value='31'/>
<sibling id='2' value='21'/>
<sibling id='3' value='10'/>
</distances>
</cell>
</numa>
</cpu>
Xen xl.cfg domain configuration:
vnuma = [["pnode=0","size=2048","vcpus=0-1","vdistances=10,21,31,21"],
["pnode=1","size=2048","vcpus=2-3","vdistances=21,10,21,31"],
["pnode=2","size=2048","vcpus=4-5","vdistances=31,21,10,21"],
["pnode=3","size=2048","vcpus=6-7","vdistances=21,31,21,10"]]
If there is no XML <distances> description amongst the <cell> data the
conversion schema from xml to native will generate 10 for local and 20
for all remote instances.
