Hi, is it running on both hosts? If you just see it in the host list but offline then is normal.

    Hi
    i have a problem that after the live migration based on shared
    storage.

    as

        migrate --live vm1 qemu+ssh://destination/system

    I found that the vm1 is also on the source host.

    I can open two vm1s both on source host and destination host.

    And I found the MACs of them are the same .

    Can anyone tell me that  it is right?
    Thanks


live migrate does ONLY that (rough list, not intended to correlate exactly with current code):

1. start up remote instance
2. copy first pass of memory
3. check difference, LARGE=copy another pass while active
4. pause source and destination
5. copy last difference
6. shutdown source
7. resume destination

The rest is left up to you.

1. on destination: virsh dumpxml <domain> > /tmp/file$$
2. on destination: virsh define /tmp/file$$
3. on source: virsh undefine <domain>

Some scenarios may want to do different things, so its left up to you what to do after a migrate.

Good Luck
