I have a problem with network interfaces after installing Xen.
[root@dom0 ~]# uname -r
3.2.2-1.fc16.i686.PAE
[root@dom0 ~]# yum list | grep xen-hyper
xen-hypervisor.i686 4.1.2-2.fc16 @updates
With default kernel system works perfectly. But after booting with xen kernel
# dmesg | grep eth

Network interface has network address but can’t to bring up.
I don't understand that happens. A difference between loadings only in irq. 20,21 for default kernel and 5,9 for xen kernel. But 5 and 9 irq is not used anywhere more.
