Subject: Add PCI sysfs reset access
X-Git-Tag: CVE-2011-1486~52
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2090b0f52d8270c38c6157b6f8fdd00fa265c213;p=thirdparty%2Flibvirt.git

Add PCI sysfs reset access

I'm proposing we make use of $PCIDIR/reset in qemu-kvm to reset
devices on VM reset.  We need to add it to libvirt's list of
files that get ownership for device assignment.
