Subject: [PATCH] libxc: correct error message in xc_sr_common.c
Date: Thu, 10 Aug 2017 13:24:27 +0200	[thread overview]
Message-ID: <20170810112428.5769-1-jgross@suse.com> (raw)

When the record length for sending the p2m frames in a migration
stream is too large, the issued error message is not very helpful:

xc: Record (0x00000003, x86 PV P2M frames) length 0x8 exceeds max
    (0x800000): Internal error

When printing the error use the size which was tested instead that of
the record header length.
