Subject: Create hostdevmgr in UserRuntimeDirectory for session libvirt
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=63f22dc80f14ca0d4a623838ec415b406d7e693c;p=libvirt.git

Create hostdevmgr in UserRuntimeDirectory for session libvirt

Without this, session libvirt won't start if it fails to create
the directory.
