[Xen-devel] [PATCH v6 2/6] libxl: modify libxl__logv() to only log valid domid values

[Paul Durrant <pdurrant@xxxxxxxxxx>]

Some code-paths use values other than INVALID_DOMID to indicate an invalid
domain id. Specifically, xl will pass a value of 0 when creating/restoring
a domain. Therefore modify libxl__logv() to use libxl_domid_valid_guest()
as a validity test.
