[libvirt] cgroups and USB passthrough devices don't work together
Hi all, beside the problem with USB devices I sent the patch for earlier, there is another problem that I'm not sure how to fix: the QEmu cgroup is _not_ allowed to access the device when adding it to the virtual machine. Basically it'd need a call to virCgroupAllowDevicePath() when adding the device… -- Diego Elio Pettenò — “Flameeyes” http://blog.flameeyes.eu/ If you found a .asc file in this mail and know not what it is, it's a GnuPG digital signature: http://www.gnupg.org/

Yep, looks like the qemudSetupCgroup method forgot about adding the ACLs for USB device nodes.
