Subject: Bump tmem pool version to 1 to fix restore issue when tmem enabled
Date: Tue, 18 Sep 2012 20:07:07 -0700 (PDT) [thread overview]
Message-ID: <2c58eb85-429e-4dc6-942b-f59414a6b399@default> (raw)
Restore fail when tmem enabled both in hypervisor and guest.
This is due to spec version mismatch when restore a pool.
