[Xen-devel] [PATCH] tools/xl: use libxl_domain_info to get domain type for vcpu-pin

[Igor Druzhinin <igor.druzhinin@xxxxxxxxxx>]

Parsing the config seems to be an overkill for this particular task
and the config might simply be absent. Type returned should be either
LIBXL_DOMAIN_TYPE_HVM or LIBXL_DOMAIN_TYPE_PV but in that context
distinction between PVH and HVM should be irrelevant.
