Hi,all.
I create a hvm which boot up from gentoo livecd iso file, the config
file 'xen/configs/gentoo' is as follows:
------------------------------
# -*- mode: python; -*-
import os, re
arch_libdir = 'lib'
arch = os.uname()[4]
if os.uname()[0] == 'Linux' and re.search('64', arch):
arch_libdir = 'lib64'
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 2048
shadow_memory = 8
name = "centos"
vcpus=1
vif = [ 'type=ioemu, mac=00:16:3e:00:00:12, bridge=xenbr0' ]
disk = [
'phy:/dev/sda6,sda,w','file:/root/downloads/install-amd64-minimal-20110113.iso,hdc:cdrom,r'
]
cdrom = 'dev/hdc'
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
boot="dc"
sdl=0
opengl=0
vnc=1
vnclisten="0.0.0.0"
vncpasswd=''
vncconsole=1
stdvga=0
serial='pty'
usbdevice='tablet'
------------------------------
Then i create this vm using command:
xm create /xen/configs/gentoo
When i entered into the console of this vm, I cannot see eth0 using
ifconfig command but only see lo interface is up
The tail of /var/log/messages on dom0 is as following:
-----------------------------------------------

When i booting hvm, i can see tap1.0 and vif 1.0 is up but then they
disappeared while booting finished

---------------------------------------------------------
While booting finished, the brctl shows as following:
-----------------------------------------------------------
server log # brctl show
bridge name bridge id STP enabled interfaces
eth0 8000.00259008c38a no peth0
----------------------------------------------------------
I tried to change vif type to netfront, eth0 interface is up after
booting from gentoo livecd. I don't understand why xen failed to load
eth0 using 'type=ioemu'?
Anyone help me?
