VIMAGE is an experimental feeature and not yet officially supported. 
freebsd-virtualization@ is the best place to get the right people to 
help rather than PRs.

I have a virtualized carp(4) in perforce but it'll depend 
on other fixes.  Meanwhile track.

I have fixes in perforce that depend on more stuff; planning

Move it back to the list for the moment.  Easier to have all 
open problems at one single point.

Fix kernel panic when using CARP with VIMEGE enabled kernel

While initial PR is for FreeBSD 8, the same kernel panic occurs on 9.3-RELEASE. This bug was fixed for FreeBSD 10 (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=164696) but still exists in 8.x and 9.x. The patch is for 9.3-RELEASE.

I hope the patch will be merged to the source tree. Thanks.
