As far as I can see from the upstream discussion this is indeed a kernel
issue. Initially it was intended to be fixed by
Author: Mel Gorman <mgor...@suse.de>
xen: properly account for _PAGE_NUMA during xen pte translations
...
Steven Noonan forwarded a users report where they had a problem starting vsftpd
on a Xen paravirtualized guest, with this in dmesg: BUG: Bad page map in
process vsftpd pte:8000000493b88165 pmd:e9cc01067
...
However the patch got reverted later (which also made it back into 14.04
via stable because it caused regressions on migration. With v3.15-rc2
there was a new change to address this:
commit 29c7787075c92ca8af353acd5301481e6f37082f
Author: Mel Gorman <mgor...@suse.de>
mm: use paravirt friendly ops for NUMA hinting ptes
It looks that change (while tagged for stable) has not yet been picked
up for 3.13.
