Strange to see NULL, NULL, NULL
No MAC prefix needs?
No desire/need to have post parse callbacks? IOW: Things to check after
all the parsing is done so that you can verify things work together?
Guess I'm unclear why this is being done here.
Looking forward - I see patch 14 makes use of it, so that's where it
should be moved to.

There's VIR_ROUND_UP or VIR_ROUND_UP_POWER_OF_TWO
Not sure if you meant power of 2 instead multiple of 2MB

More of these strange constructs *tab_props, *params... consider
tab_props[0]->
tab_props[1]->
params[0]->
params[1]->

Since these two are so similar - check out what the qemu driver code does:
static int qemuDomainSetMaxMemory(virDomainPtr dom, unsigned long memory)
{
return qemuDomainSetMemoryFlags(dom, memory, VIR_DOMAIN_MEM_MAXIMUM);
}
Then in qemuDomainSetMemoryFlags, there's a check:
if (flags & VIR_DOMAIN_MEM_MAXIMUM) {
} else {
}
Of course there's also an extra flags check for VIR_DOMAIN_MEM_MAXIMUM
in qemuDomainSetMemoryFlags
It's up to you though to determine how similar and whether any merging
of the two could be done...
