https://bugzilla.kernel.org/show_bug.cgi?id=201825 --- Comment #9 from Larkin Lowrey (llowrey@xxxxxxxxxxxxxxxxx) --- The 'no-kvmapf' kernel param does work, when I add it to the guest kernel command-line. The kernel docs were not clear so I had been adding it to the host kernel command-line. My torture test normally hangs due to try_async_pf after between 20min and 4 hours. I ran overnight for at least 18 hours without issue. My host and guests are completely stable when I disable async page faults in the guests. -- You are receiving this mail because: You are watching the assignee of the bug.
