Subject: libxl: don't attempt to resume domain when suspend fails
X-Git-Tag: v1.2.19-rc2~5
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=15120b8c61014a9263cb53314076da9a44e39621;p=thirdparty%2Flibvirt.git

libxl: don't attempt to resume domain when suspend fails

Failure of libxl_domain_suspend() does not leave the domain in
a suspended state, so no need to call libxl_domain_resume(),
which btw will fail with "domain not suspended".
