Started a debugging another session today. First I confirmed with (gdb) catch syscall exit exit_group That this is the "normal" exit along the error message we knew: migrate_set_state(&mis->state, MIGRATION_STATUS_ACTIVE, = = MIGRATION_STATUS_FAILED); = = error_report("load of migration failed: %s", strerror(-ret)); = = qemu_fclose(mis->from_src_file); = = exit(EXIT_FAILURE); I found that already the retval of qemu_loadvm_state it -5. Every thing else afterwards is cleanup. Inside qemu_loadvm_state the first 2/3 pass and then that ret=3D-5 is from "ret =3D qemu_file_get_error(f);". -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1711602 Title: --copy-storage-all failing with qemu 2.10 Status in QEMU: New Status in libvirt package in Ubuntu: Confirmed Status in qemu package in Ubuntu: Confirmed Bug description: We fixed an issue around disk locking already in regard to qemu-nbd [1], but there still seem to be issues. $ virsh migrate --live --copy-storage-all kvmguest-artful-normal qemu+ssh= ://10.22.69.196/system error: internal error: qemu unexpectedly closed the monitor: 2017-08-18T1= 2:10:29.800397Z qemu-system-x86_64: -chardev pty,id=3Dcharserial0: char dev= ice redirected to /dev/pts/0 (label charserial0) 2017-08-18T12:10:48.545776Z qemu-system-x86_64: load of migration failed:= Input/output error Source libvirt log for the guest: 2017-08-18 12:09:08.251+0000: initiating migration 2017-08-18T12:09:08.809023Z qemu-system-x86_64: Unable to read from socke= t: Connection reset by peer 2017-08-18T12:09:08.809481Z qemu-system-x86_64: Unable to read from socke= t: Connection reset by peer Target libvirt log for the guest: 2017-08-18T12:09:08.730911Z qemu-system-x86_64: load of migration failed:= Input/output error 2017-08-18 12:09:09.010+0000: shutting down, reason=3Dcrashed Given the timing it seems that the actual copy now works (it is busy ~10 = seconds on my environment which would be the copy). Also we don't see the old errors we saw before, but afterwards on the act= ual take-over it fails. Dmesg has no related denials as often apparmor is in the mix. Need to check libvirt logs of source [2] and target [3] in Detail.
