Almost. Firstly, there's VIR_DOMAIN_MEMORY_STAT_LAST_UPDATE which is not
handled either. Secondly, these two macros were introduced in libvirt
2.1.0. So we need a check that enables them iff building with 2.1.0 or
newer. I'm fixing both issues and pushing. I wonder if there's something
we can do to not forget about macros like these again.

You mean like this?  Or am I missing a reason why this won't work?

Oh right. Apparently some time off is in place :-) Either of you care
posting the patch?

Not erally, feel free to reuse that ^^, but someone could take their
time to check that it's done for all appropriate switches.

Have a nice day,
