[Xen-devel] Missing blktap(2) driver in kernel-2.6.32-*.el6.xendom0.x86_64.rpm
I''m not sure if this belongs here, but someone in the ##xen channel in irc.freenode.net told me to message this list and let people know about and/or inquire as to why the blktap (or better yet blktap2) driver is not included in M A Young''s aforementioned kernels, blkbackend is there but it does not allow for tap:aio disks in the domU''s. Thanks, David _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
