We are running Havana on EL6, we rely pretty heavily on live storage
migrations setup like so:
block_migration_flag=VIR_MIGRATE_UNDEFINE_SOURCE,VIR_MIGRATE_PEER2PEER,VIR_MIGRATE_NON_SHARED_INC,VIR_MIGRATE_LIVE
and it works great.
I am currently building a new stack based on EL7 and Juno, however when I
attempt to do a migration (nova live-migration --block-migrate x), i
receive the following:
libvirtError: internal error: unable to execute QEMU command 'migrate':
this feature or command is not currently supported
I've found a couple of related BZs:
https://bugzilla.redhat.com/show_bug.cgi?id=1022393
https://bugzilla.redhat.com/show_bug.cgi?id=1020495
Am I understanding this correctly that they have completely removed this
feature from RHEL7? Unless I'm running the RHEV variant of qemu-kvm??
