Subject: Assign virtio-serial addresses after coldplugging a device
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=083c33b3243da8ab266c0ff75b6abb217bcbf440;p=people%2Fliuw%2Flibxenctrl-split%2Flibvirt.git

Assign virtio-serial addresses after coldplugging a device

Otherwise we might allow coldplugging a device
that uses an address that is already occupied, creating
an unstartable domain.
