Try this one instead of the "Patch to add extra tlbsyncs". Ben H pointed out that it is ptesync which is important, not tlbsync (which is actually a no-op, though architecturally required), so this version adds a ptesync to the guest exit path as well as the tlbsync. ** Attachment added: "Patch to add extra tlbsyncs and ptesyncs" https://bugs.launchpad.net/bugs/1768115/+attachment/5137005/+files/extra-ptesync.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768115 Title: ISST-LTE:KVM:Ubuntu1804:BostonLC:boslcp3g1: Migration guest running with IO stress crashed@security_file_permission+0xf4/0x160.
