RE: How to set up a NAT networking for xen 4.2.5 domu without xend-config.sxp

[Fu, Zeyi (付泽义) <Zeyi.Fu%mtuzhuhai.com@localhost>]

It sounds discouraging,  but  vif = [ 'type=ioemu,bridge=bridge0' ]   is working,  I can get the tap0 interface, I think vif-bridge is called.

But when I try to set up a NAT networking, I remove the bridge0 interface, I set that vif-ip will be called, as a result I get the xvif interface which get the expected ip addr,  everything seems fine but ...   :(    

Any more suggestions and tips ?  Thank you.


Best regards 

John Fu

It's a HVM domU. So I guess the vif script is not called for the tap
interface, instead the qemu-ifup script is called. AFAIK there's no
way to change this script from the config file, you may need to hack the
script itself.

For a HVM domU, unless you have PV drivers for the network interface,
the interface used in the dom0 is a tap interface, not the xvif one.
