There was a bug a while back which resulted in high-numbered xbd
devices not showing up; I fixed that three years ago in r255051,
shortly before stable/10 branched.

The freebsd-xen list has been the de facto forum for discussing FreeBSD/EC2

in using FreeBSD on clouds (as opposed to, say, writing Xen kernel code) to
migrate over to the freebsd-cloud list.

Hi all,
As of r266269, stable/9 can run in Xen/HVM environments using the GENERIC
kernel configuration plus a new xenhvm.ko. This will allow FreeBSD 9.3 to

is placed in /boot/loader.conf.
