------- Comment From mcintire.com 2011-06-21 16:48 EDT-------
Red Hat, the reason we are submitting this feature, even though late, is that Libvirt support is required for customers to use RH feature BZ  633563 (IBM feature BZ 67309) in the context of KVM virtualization..

Comment 5 Dave Allan 2011-06-24 17:18:19 UTC
This BZ is a duplicate of 692769, which was filed by Fujitsu.  They have agreed to consolidate, and you should now have access to that BZ.  Do you mind if I consolidate by closing this BZ as a duplicate of 692769?

Red Hat.  We are fine with closing as a dup, but please ensure we have access to the Fujitisu feature request.

Comment 7 John Jarvis 2011-06-24 18:22:26 UTC
Verified IBM has access to BZ 692769 , closing as duplicate.
