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 .

So when you first "xm create" it, it's ok, and after you reboot the guest, the NIC model has changed?

Someone can confirm the bug in centos 5.5 ?

Did you search Redhat bugzilla?

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"
