Run your VMs using seccomp filter for improved security against qemu exploits. For more details, please see:


Nothing beyond the initial test day setup (basically a function F18 VM).

This is all currently broken
QEMU guests fail at startup using libvirt + seccomp: [bz 855192]

How to test

  1. Verify a VM starts up fine, to start.
  2. Stop all VMs
  3. Edit /etc/libvirt/qemu.conf, change seccomp_sandbox = 1
  4. Restart libvirtd
  5. Start a VM, connect to the graphical console with virt-manager
  6. Verify that the VM seems to be behaving as usual.

Expected Results

No obvious errors occur, guests seem to function like normal after all the steps.
