You're obviously running a 64-bit kernel, and presumably that CPU supports NPT, so the only way KVM should reach the failing allocation is if NPT is being explicitly disabled. There's nothing wrong with using shadow paging, it's just uncommon these days. NPT aside, the interesting part of the failing allocation is that it uses GFP_DMA32. I did a quick test to force that allocation on my system and nothing exploded. Odds are good the bug is outside of KVM, which means a bisection is probably necessary. -- You are receiving this mail because: You are watching the assignee of the bug.
