I'm trying working with Xen and I've tryed to build up a virtual machine in domU. I'm using the following configuration for the domU

kernel = '/media/home_separata/domU_kernel/boot/vmlinuz-linux'                  
ramdisk = '/media/home_separata/domU_kernel/boot/initramfs-linux.img'
name = "domU_Arch_linux"
root = '/dev/xvda1 ro'
disk = ['file:/media/home_separata/domU_kernel/arch_linux_kernel.img,xvda1,w']
vif = ['mac=aa:::10:11:f1,ip=192.168.0.2,bridge=xenbr0']

when I try to create this vm with "xm create" it works fine except that it doesn't bring up vif interfaces in dom0, so the virtual machine had no access to the net.

Does anyone have any idea about this problem?

Use the virt-manger to see if the vif interface is enabled ? – Chakri May 1 '12 at 16:11
What settings do you use for networking in XEN? Please post the according lines of your xend-config.sxp file. – Nils Oct 12 '12 at 21:05
What does you xend.log say during DomU creation? – Nils Oct 12 '12 at 21:06

Your config file should probably call a Xen networking script to setup apropriate interface on xenbr0. Set up last line like this - 

vif = ['mac=aa:::10:11:f1,ip=192.168.0.2,bridge=xenbr0,script=vif-bridge']

The default should be configured in xend-config.sxp. – Nils Oct 12 '12 at 21:06
