Hi Michal, We're testing libvirt-1.2.13 and found it failed to live migrate domains with attached network drives. The change to libvirt was made in commit cf54c606, announced here: https://www.redhat.com/archives/libvir-list/2014-November/msg01053.html
It's not necessary to precreate network drives. They're created during nova live migration in openstack. How about this patch? diff -U3 -r libvirt-1.2.13.orig/src/qemu/qemu_migration.c libvirt-1.2.13/src/qemu/qemu_migration.c --- libvirt-1.2.13.orig/src/qemu/qemu_migration.c 2015-02-23 22:04:12.000000000 -0800 +++ libvirt-1.2.13/src/qemu/qemu_migration.c 2015-03-18 12:18:14.137990147 -0700 @@ -1510,6 +1510,9 @@ case VIR_STORAGE_TYPE_BLOCK: case VIR_STORAGE_TYPE_DIR: case VIR_STORAGE_TYPE_NETWORK: + ret = 0; + goto cleanup; + break; case VIR_STORAGE_TYPE_NONE: case VIR_STORAGE_TYPE_LAST: virReportError(VIR_ERR_INTERNAL_ERROR, Cheers, -- Noel Burton-Krahn Sr, Distributed Systems Engineer Piston Cloud Computing
