Right now, on a virsh blockcopy, I know you can do something like this:
# Connect DEST target
iscsiadm -m node -p ${DESTINATION}:3260 -T ${VOLNAME} -o new
iscsiadm -m node -p ${DESTINATION}:3260 -T ${VOLNAME} --login
# Copy to connected iSCSI target
virsh blockcopy ${DOMAIN} vda /dev/sdc --raw --bandwidth 300
However I have libiscsi compiled into my QEMU. So I can do this with the
monitor directly (and avoid the need to call out to external iscsiadm):
virsh qemu-monitor-command ${DOMAIN} '{"execute":"drive-mirror",
"arguments": { "device": "drive-virtio-disk0", "target":
"iscsi://${TARGET_IP}:3260/${DOMAIN}/1", "mode": "existing", "sync":
"full", "on-source-error": "stop", "on-target-error": "stop" } }'
Is there a way to use the libiscsi compiled into my QEMU with virsh
blockcopy command? I haven't been able to find any examples of using
blockcopy with iSCSI compiled into QEMU.
