Subject: [Bug 220057] Kernel regression. Linux VMs crashing (I did not test Windows guest VMs)

--- Comment #42 from Alex Williamson (alex.williamson@redhat.com) ---
If it's not a physical memory limit (I'm not able to reproduce even allocating
60 1GB hugepages on a 64GB host), it may be that proxmox is imposing cgroup
memory limits on the VM. It still doesn't make sense to me how huge_fault
support could result in more memory used by the page tables though. The
previous behavior is effectively the worst case scenario where the full device
memory is mapped as ptes.
