Hi folks, This patchset adds vhost-blk support. vhost-blk is a in kernel virito-blk device accelerator. Compared to userspace virtio-blk implementation, vhost-blk gives about 5% to 15% performance improvement.

v1 was here: https://www.redhat.com/archives/libguestfs/2016-March/thread.html#00157 Not running the 'hwclock' command reduces boot times considerably. However I'm not sure if it is safe. See the question I posted on qemu-devel: http://thread.gmane.org/gmane.comp.emulators.qemu/402194 At the moment, about 50% of the time is consumed by SeaBIOS. Of this, about ⅓rd is SGABIOS

I also ran all the tests, which pass. As with the previous versions, this makes a change to the API, where you

This patch isn't ready to go upstream. In fact, I think we might do a quick 1.30 release soon, and save this patch, and also the extensive changes proposed for the test suite[1], to after 1.30. Currently it is not safe to use the same handle from multiple threads, unless you implement your own mutexes. See: http://libguestfs.org/guestfs.3.html#multiple-handles-and-multiple-threads These

We didn't expect that qemu was caching anything

Previous discussion here: https://www.redhat.com/archives/libguestfs/2015-June/thread.html#00048 v2: - Use a cleanup handler to release the lock. - Rebase to upstream. Note I have not fixed the problem(s) with error handling (patch 3).
