Subject: Print error when failing to load PCI config data
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~98^2~17
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7c59364d0329d36a7759033962a469ca714f884d;p=sdk%2Femulator%2Fqemu.git

Print error when failing to load PCI config data

When loading migration fails due to a disagreement about
PCI config data we don't currently get any errors explaining
that was the cause of the problem or which byte in the config
data was at fault.
