[libvirt] [PATCH 1/2] bhyve: add UTC clock support
Bhyve as of r279225 (FreeBSD -CURRENT) or r284894 (FreeBSD 10-STABLE) supports using UTC time offset via the '-u' argument to bhyve(8). By default it's still using localtime. Make the bhyve driver use UTC clock if it's requested by specifying <clock offset='utc'> in domain XML and if the bhyve(8) binary supports the '-u' flag. --- src/bhyve/bhyve_capabilities.c | 31
