Hello ,

I use Centos 5.4 , with the redhat version of xen .
I need for some guest to change the hardware for the network .
So in my xen config i add the model option in the vif line .

When the guest boot , i had the right emulation , but after a reboot , the guest loose the configuration .

Someone can confirm the bug in centos 5.5 ?

Have someone a patch ?



Extract of my config :

   builder = "hvm"
   vif = [ 'type=ioemu, mac=00:16:3e:50:10:45, bridge=xenbr0, model=ne2k_pci']
   device_model = "/usr/lib64/xen/bin/qemu-dm"

#grep spa.*/usr/lib64/xen/bin/qemu-dm /var/log/xen/xend.log
