[Xen-devel] [PATCH v2 0/2] x86/dom0: improve PVH paging memory calculation


There have been several reports of PVH Dom0 builder running out of
memory due to bad paging memory approximation done in
dom0_compute_nr_pages. The most recent reports is:


This series attempts to improve the situation by introducing a new
function to approximate the memory usage of HAP and IOMMU page tables.
It also takes into account whether the IOMMU page tables are shared with
HAP or not when calculating the amount of available memory.

It can be found on the following git repo:

git://xenbits.xen.org/people/royger/xen.git dom0-paging-v2

Thanks, Roger.
