hi tiantian,
i think i wrote you that already, but i had several problems with defining
the bridge network onto the dom0. and I also believe it is much faster to
define it directly onto the network stack. so I did then:
the [/etc/network/interfaces] script:
***
auto lo
iface lo inet loopback
auto br0
iface br0 inet static
address 10.10.10.21
netmask 255.255.255.0
network 10.10.10.0
broadcast 10.10.10.255
gateway 10.10.10.1
bridge_ports eth0
bridge_stp on
bridge_maxwait 0
auto eth1
iface eth1 inet static
address 10.255.255.1
netmask 255.255.255.0
network 10.255.255.0
broadcast 10.255.255.255
***
and at the domU script:
***
vif = [ ''bridge=br0,mac=xx:xx:xx:xx:xx:xx'' ]
***
the [/etc/xen/xend-config.sxp] script:
***
(network-script ''network-bridge antispoof=yes'')
(vif-script vif-bridge)
***
the [/etc/sysctl.conf] script to activate routing on startup:
***
kernel.domainname = local.net
#kernel.printk = 3 4 1 3
#net.ipv4.conf.default.rp_filter = 1
#net.ipv4.conf.all.rp_filter = 1
#net.ipv4.tcp_syncookies = 1
net.ipv4.ip_forward = 1
net.ipv6.conf.all.forwarding = 1
#net.ipv4.conf.all.accept_redirects = 0
#net.ipv6.conf.all.accept_redirects = 0
#net.ipv4.conf.all.send_redirects = 0
#net.ipv4.conf.all.accept_source_route = 0
#net.ipv6.conf.all.accept_source_route = 0
#net.ipv4.conf.all.log_martians = 1
***
about your point 2), if there is no network, there is also no NFS (Network!
File System) J
and my last point is, I always had serious problems with IOEMU. I don''t
know
if it is linked with my 1 year old hardware or if it is just too buggy. I
left it everywhere away and it works for my J
thanks walter

Subject: [Xen-users] How to configure vif in Xen?
Hi
I built Xen-4.2-unstable and kernel-2.6.32.40 on CentOS 5.5 successfully!
I also implemented fault tolerance and high avaliability via remus under
your advices!
Thank you very much!
But I got new problems:
1. The vif of VM didn''t work, when I start a new VM by command:
"xm cr
myvm.hvm", system returned message: "the <VM> does not
exist".
my VM''s configuration file is:
ernel = "hvmloader"
builder=''hvm''
memory = 512
name = "myvm"
vcpus=4
vif = [ ''type=ioemu, bridge=eth0,mac=00:16:3e:3a:7a:dd'' ]
pae = 1
acpi = 1
apic = 1
#disk = [ ''file:/home/xen/tpl/hvm/base.img,hda,w'',
''file:/home/xen/tpl/hvm/CentOS-5.5-x86_64-bin-DVD-1of2.iso,hdc:cdrom,r''
]
disk = [ ''file:/home/xen/tpl/hvm/win.img,hda,w'',
''file:/home/xen/tpl/hvm/windows-XP.iso,hdc:cdrom,r'' ]
&n! bsp; device_model = ''qemu-dm''
boot="cd"
sdl = 0
vnc = 1
vnclisten = "0.0.0.0"
stdvga = 0
serial = "pty"
if I deleted the "vif = [ ''type=ioemu,
bridge=eth0,mac=00:16:3e:3a:7a:dd'' ]" , the vm started
successfully, but the
VM could not access network.
I have installed the bridge-utilty package properly.
I checked the /val/log/message, it showed:
Jul 29 04:04:34vnix06 kernel: [ 205.540203] device vif1.0 entered
promiscuous mode
Jul 29 04:04:34 vnix06 kernel: [ 205.545969] eth0: port 2(vif1.0)

backend/vbd/1/5632/node failed.
Jul 29 04:04:35 vnix06 logger: /etc/xen/scripts/block:
/etc/xen/scripts/block failed; error detected.
could you tell me how to address this problem?
2. The NFS worked well in CentOS5.5, but when I compiled kernel-2.6.32-40
and Xen-4.2-unstable and got into dom0.
the NFS didn''t work, and could not mount the remote NFS server. I
tried
command: "service nfs restart", but the failed.
I used command: "mount <IP>:/home /mnt", the system returned:
mount <IP>/home /mnt
! mount.nfs: No such device
&n! bsp; wha t''s wrong?
I am waiting for your help! thank you very much!
