Failed to bring up network interface

["Sergey A. Pechiony" <psa@xxxxxx>]

I have a problem with network interfaces after installing Xen. Network interface has network address but can’t to bring up.

 

[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

 

With default kernel system works perfectly. But after booting with xen kernel

 

# dmesg | grep eth

# lspci | grep Ethernet

# ifup em1

# ifconfig em1 192.168.129.1

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.
