Hi Daitsuke,

This issue should be fixed by Prachi at:

commit 58ac2420b3d7acb4b61029fbba5b323939c5315c
Author: prachi <prachi@cloud.com>
Date:   Wed Apr 11 16:15:19 2012 -0700

    Bug 14646 - Enabling Host into maintenance mode is stopping the
VMs instead of live migrating them to other hosts in the cluster.

    Changes:
    -  While listing UP hosts in the cluster of the host, the query
has changed and now also considers the Host 'resourceState' field and
picks only those hosts
       This query result does not include the host being put in
maintainance; unlike the earlier query that used to include it.
    -  But the logic to find out if this is the last host in the
Cluster is not updated and has a bug when it compares the list size.
    - Fixed this

The fix would be in 3.0.2 release.
