Subject: libxl: copy persistent domain definition while starting a guest
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=6aff1e9ca52ba68efa4982910d6e806af1ff7e82;p=people%2Fliuw%2Flibxenctrl-split%2Flibvirt.git

libxl: copy persistent domain definition while starting a guest

We should make a copy of current definition to preserve a persistent
definition, because we later update the definition with live changes.
The live definition is discarded on domain shutdown and replaced by the
copy we make before starting the domain.
