Switch to using a blktap provided by the system, rather than building it in-tree.
Do this by adding a block-tap script which calls the tap-ctl binary, rather than linking against a library. This requires the use of an externally-built tap-ctl binary, which an be built from the master branch of the XenServer blktap tree at https://github.com/xapi-project/blktap.git The first two patches and the final patch are general libxl disk handling improvements which can be applied independently of the core. The third patch (tools: Add a block-tap script for setting up tapdisks via tap-ctl) can also be checked in independently from the fourth and fifth, as it allows someone to disable blktap support in configure but still use externally-built tap-ctl binaries (albeit with a different disk string). The fifth patch is a straight rm -rf of toosl/blktap2. Rather than spam everyone's mailboxes I've clipped the message here, and provided a tree which can be pulled from: git://xenbits.xen.org/people/gdunlap/xen.git out/blktap-system/v1 This series also exposes blktap to a bug that prevents HVM guests from using disks created with block scripts. This should be a blocker for the 4.6 release, so I think we should consider checking this series in as is, assuming that bug will be addressed before the release.
