Do we really need such verbose XML. At the very least the 'num' attribute is redundant, since you can trivially do count(/topology/cells/cell) or count(/topology/cells/cell[@id=0]/cpus/cpu) XPath exprs in both cases.
The addition of extra tags every time we have a list is not the style we have normally used in libvirt. eg, we don't use
<disks> <disk> .. </disk> <disk> .. </disk> </disk>
to surround the list of disks in a domain.
I'd prefer to see it looking more like this:
<topology> <cell id='0'> <cpu id='0'/> <cpu id='1'/> <cpu id='2'/> <cpu id='3'/> </cell> </topology>
Regards, Dan.
That would simplify the code since the counts wouldn't need to be known up front. This was the format suggested by Daniel V and I used it, assuming he knows more about libvirt's desired/required xml structure. -- Elizabeth Kon (Beth) IBM Linux Technology Center Open Hypervisor Team email: eak@us.ibm.com
