And the upstreaming of VND is likely not to happen with this release.  That blocks us from properly catching up with illumos-kvm-cmd.

There are several commits (Starting with the March 19th one we can't bring in w/o VND) here:

	https://github.com/joyent/illumos-kvm-cmd/commits/master

Currently, we only backport the most recent fix about QEMU using preadv/pwritev recklessly.  IF (big if) there are other commits we can backport, you could try it using the patches/ directory of omnios-build.  I'm thinking maybe HVM-807's may help you (provided that's indepdent of VND support).

Have you seen anything with dtrace or lockstat that could give a clue to what's holding things up?  I don't recall seeing anything observed.

I'm sorry, but that does appear to be the case.

Next week I disappear for other-customer work, but starting in March, I'm doing nothing but r151014.
