Re: [libvirt] [Xen-devel] converting gatewaydev= from domU.cfg to libvirt.xml fails

How should this be converted?

/etc/init.d/boot.local
tap=xentap
tunctl -pt ${tap}
ip addr add 1.1.1.1/29 dev ${tap}
ip link set up dev ${tap}

domU.cfg
vif=[
'mac=00:16:3e:13:01:00,ip=1.1.1.2,type=vif,gatewaydev=xentap,script=vif-route'
]


The result from "convert-xml xen-xl domU,cfg" is:

     <interface type='ethernet'>
       <mac address='00:16:3e:13:01:00'/>
       <ip address='1.1.1.2' family='ipv4'/>
       <script path='vif-route'/>
     </interface>

gatewaydev= is missing, the guest will not start.

libvirt doesn't support 'gatewaydev'. I'm certainly no expert in this area, but is it possible to convert your host config in boot.local to a libvirt routed network [1] and then have the guest use it with something like

  <interface type='network'>
    <source network='boot.local.equiv'/>
    ...
  </interface>
