Description Daniel Berrange 2010-05-27 10:21:38 UTC
Description of problem:
Latest QEMU has a virtio driver for the p9fs filesystem, to allow host directories to be passed through to the guest. This is a very useful feature and needs to be supported in libvirt's QEMU driver.

 - Hook up the existing <filesystem> tag
 - Integrate with SELinux security driver

    Implement support for virtio plan9fs filesystem passthrough in QEMU

The SELinux sVirt driver still needs to have support for relabelling the filesystem tree.
