Any bug reports to lcfg-xen have been applied to lcfrg-libvirt as well. Any future bug reports to lcfg-xen will be applied to lcfg-libvirt where there's common code/functionality.

For XEN hosts, the following header (libvirt_xen.h) is required:

To have libvirt work effectively, it requires active bridge networking. lcfg-network supports this:

A patch for lcfg-network was created to support the creation of bridge interfaces. The following should do the trick once a new release of the lcfg-network component will be availalbe:

!network.interfaces     mADD(eth0 br0)
!network.hwaddr_eth0    mSET(XX:XX:XX:XX:XX:XX)
!network.bridge_eth0    br0
!network.ipaddr_br0     DHCP
!network.type_br0       Bridge
