Hello, 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:
https://lists.xenproject.org/archives/html/xen-devel/2018-11/msg03103.html 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-v1 Thanks, Roger.
