[Xen-devel] Re: [PATCH 3/7] libxenlight resend: 8mb physmap slack for pv domains



The p2m is *inside* the pv guest. So the only "impact" is infinitesimally increasing the chances of an oom_killer going postal. This is not for hvm's with external p2m's

No extra memory is being allocated at all in any way. The only impact is a wee bit larger p2m table.

yes, and that consumes memory. not sure that's one we care about in XCP,
but as a rule to not make any exceptions, i want the amount to be explicetly
tracked.

note that also, whilst xend didn't have much done regarding memory stuff,
xapi (the ocaml daemon running instead of xend in XCP) have load of changes
regarding how we allocate and track things.
