Re: [Xen-devel] [PATCH] xenmon: remove magic number "31" (the idle domain)

Therefore, xenmon supports only up to 32 domains.

That's poor, since it in fact only really supports the first 31 domains created on a system (domain ids don't necessarily quickly get reused; and 32nd domid is used as sentinel to indicate idle). It shouldn't be hard to use a data structure more complicated than (presumably) a small array indexed by domid.

I know about this problem. I've got a fix for it I prepared some time ago but never got around to submitting. I'll integrate it with the latest source and get it sent out this week.
