Subject: [PATCH] libxl: fail with distinct error on unsupported PM suspend
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When guest cooperation is required but not supported by its OS, return
with VIR_ERR_OPERATION_UNSUPPORTED error, instead of generic
VIR_ERR_INTERNAL_ERROR.
