I believe the customer has asked to close this bug. Canonical, please confirm.

There are a couple of points about the CMA and HPT allocations:
1. The HPT is probably getting sized according to the maximum memory of
the guest, not the initial amount of memory. Since we haven't been given
any specifics about the

I think the key patch (from LP 1632045) was pulled in as of 4.4.0-51.72. As
far as I can tell, the CMA debugging is not in ubuntu (actually, I'm not
positive it was even pulled in upstream, but that's less immediately
important).

I'm still looking. I'm confident that daniel has correctly identified and
explained the failure mode (i.e. out of enough CMA to create guests). I also
don't *think* we have enough information at the moment to say for sure why this

Looking though the qemu logs, I'm not seeing anything obvious, though I will
have a colleague look at them also on Monday. I see that even "some time later"
we have a system with 512gb of RAM, the usual default 5% in CMA (25gb) and
Hi,

showing symptoms - due to the intermittent nature of the problem it
was taken some time later. This matches what I see in the logs so I
have no reason to doubt it.

Daniel

Thanks, Daniel. Are you confident that the provided logs, etc. are taken from a
machine that is currently actually showing the symptoms? The customer does tend
to take the view that all machines are the same at all times. I don't wa

Clearly, the general problem of running out of CMA allocatable space is not
soluble in the current architecture, anyway. However, this is exactly why we
need to know the particular situation at hand to understand this particular
