Another patch to try. This one adds some tlbsync instructions which we were missing. It applies to the Ubuntu bionic kernel tree and should be applied to the host kernel (it will do nothing in the guest). The other patch to take the mmu_lock also is a host kernel patch and will do nothing in the guest. I suggest applying both to start with, and if that fixes the problem, then try with just this one. ** Attachment added: "Patch to add extra tlbsyncs" https://bugs.launchpad.net/bugs/1768115/+attachment/5136671/+files/extra-tlbsync.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.
