--e89a8f2351f5e8d74a04c546ccdc Content-Type: text/plain; charset=ISO-8859-1 I tried to use the prebuilt vm1.tar.gz from http://people.freebsd.org/~neel/bhyve/vm1.tar.gz. Rest of the steps are as described in my earlier e-mail thread. When I try to run the vm1, I get kernel panic. I am attaching herewith the backtrace for the kernel panic when I run the prebuilt vm1 (from Neel's home directory).
