# guest::load
|
|
# this function is responsible for doing any pre-load tasks for a guest.
|
|
# for non uefi guests this normally means running bhyveload or grub-bhyve.
|
|
# this function should return a non-zero value if there's a problem
|
|
# or 0 on success.
|
|
# As this is called from within the scope of vm::run,
|
|
# the following variables are already set (among others)
|
|
#
|
|
# _name: guest name

# _loader: boot loader to use (grub|bhyveload)

# _conf: full path to guest config file
|
|
# _cpu: cpu count
|
|
# _memory: RAM
|
|
# _guest: guest type
|
|
# _bootdisk: full path to primary disk
|
|
#
|
|

|
|
# and is much more readable when all the util::log* calls line up
