[libvirt] [PATCH 0/2] bhyve: implement connectDomainXMLToNative
One thing I'm wondering about. Bhyve has two step domain startup: 1. bhyveload 2. bhyve This implementation prints out only 'bhyve' command. Should it also print bhyveload command and if yes, how should it look for a user, something like 'bhyveload ... ; bhyve ...' ?

I'd suggest printing both commands, separated by a new line.

Good, I'll upload v2 with both commands printed as you suggest. Roman Bogorodskiy
