Re: [Xen-users] no pci support in xen-3.0.1 with gentoo?

Hi, Mats,

Thanks for your help.

By default, no network interfaces are configured. When I added following 
line in my xen config file /etc/xen/rhel4
vif = [ '' ], i got guest network interface in domain 0:

sipxpbx ~ # ifconfig

But in my guest rhel, i don't find network interface:
[root@genxen ~]# ifconfig
lo        Link encap:Local Loopback
         inet addr:127.0.0.1  Mask:255.0.0.0
         inet6 addr: ::1/128 Scope:Host

         RX packets:0 errors:0 dropped:0 overruns:0 frame:0
         TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:0
         RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)


Could you give me any hint?
