[libvirt] [PATCH 1/6] Pass the virt driver name into security drivers
Daniel P. Berrange
berrange at redhat.com
Fri May 11 10:10:01 UTC 2012
From: Daniel Walsh <dwalsh at redhat.com>
To allow the security drivers to apply different configuration
information per hypervisor, pass the virtualization driver name
into the security manager constructor.
