Pkg xen devel - Oct 2010 - Bug#586772: xen-utils-4.0: No block tap backends available

Package: xen-utils-4.0
Version: 4.0.1-1
Severity: normal

Due to license issues this version of Xen does not include the blktap2 backend
(tapdisk2) and associated utilities (vhd-util, etc.). The decision was made to
disable the blktap v1 kernel module (the default is now blktap2). As a result we
can't use any tap devices which means worse performance than previousl.
Since blktap1 was available in lenny this could be looked on as a regression.

Please consider either adding blktap2 or reinstating the blktap1 kernel module.

I thought there was no real licensing issue. I recall some patches on xen-devel
about that.
