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

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)
I know the reason. ifconfig could not find unactive network interface.
When use iptables command ip. i found eth0 ;-)
[root@genxen ~]# ip a
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

3: sit0: <NOARP> mtu 1480 qdisc noop

Could you give me any hint?

Any suggestion?
The virtual machine has no PCI devices, until you assign some PCI
slots to this machine.
And the assignment of PCI slots is also not working in 3.0.1
So you mean I could not use pci devices such as ethernet
device with
xen 3.0.1? if it's true, that's too bad cause a Linux
without network
function is nothing.
You can certainly get network functionality in DomU - you
just can't
get directly to the actual physical PCI device.
Generally, the DomU is linked to the rest of the world through a
"bridge" device - which is just a piece of software that
transfers the
data to Dom0, where Dom0 decides whether it's going to send
it to the
Ethernet card or just transfer it to another domain - or perhaps
answer itself (in case you ping dom0 for instance).
Could you tell me how to use bridge with xen?
I guess the best way to describe it is here:
