Problem with xen hvm DomU

[Christoph]

I think its again a translate error of domxml-from-native...

This is the line in xl config:

vif = [
"mac=00:16:3e:05:30:04,bridge=xenbr5,script=vif-bridge,type=vif",
"mac=00:16:3e:04:30:04,bridge=xenbr4,script=vif-bridge,type=vif",
"mac=00:16:3e:15:30:04,bridge=xenbr15,script=vif-bridge,type=vif",
"mac=00:16:3e:14:30:04,bridge=xenbr14,script=vif-bridge,type=vif" ]

in xen if I want to use more than 3 nic's I need to define the
"type=vif". With default or e1000 as type it doesnt work for >3 nic's

The translated config is:

<interface type='bridge'>
       <mac address='00:16:3e:05:30:04'/>
       <source bridge='xenbr5'/>
       <script path='vif-bridge'/>
       <model type='netfront'/>
</interface>
...

there is the type "netfront" and nothing about type=vif. I've tried to
set it to model type='vif' but it doesnt work to...
