[Xen-devel] [PATCH RFC OSSTEST v1 02/12] target_var: Support fallback to all_(guest|host)_$vn

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

Having to set {ident}_foo for all idents used in a job (e.g host vs
src_host+dst_host) in make-flight would be a little fiddly.

Instead follow the lead of all_hostflags and consult all_host_$vn.

I have no immediate use for all_guest_$vn, but support it for
consistency.
