After the upgrade to 0.7.5 from the preview repository, I've noticed that a restart of libvirt does not appear to "re-acquire" any guests already running on the system.

# virsh list

# ps -ef | grep qemu-kvm

# virsh list
 Id Name                 State
  1 imap                 running
  2 mail                 running

Additionally, something doesn't appear to be getting either parsed right or set correctly when the guest is started as the /var/log/libvirt/qemu/<guestname>.log file contains: 
"Option 'ipv4: Use 'on' or 'off'" 
"Failed to parse "yes" for "dummy.ipv4"
