Description Daniel Berrange 2009-05-12 16:19:50 EDT
Description of problem:
Currently all QEMU instances for qemu:///system are run as root. This is bad for security. We need to switch to run them under a dedicated system account eg 'kvm'.  We already create TAP devices from libvirt & pass the open FD, so networking won't be a problem. This will entail having libvirt chown the disk devices prior to starting a VM, but again not a hard problem.

Likely some other fun with PCI & USB device passthrough, but we'll figure that out as we encounter it.... 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Rnu a QEMU instance under qemu:///system
Actual results:
QEMU runs as root

Expected results:
QEMU does not run as root
