Hello list,

I'm using xen2.6 with a 2.6.11 kernel

my config:
kernel = "/boot/vmlinuz-2.6.11-xenU"
memory = 1280
name = "s51"
nics=1
vif = [ 'ip=82.149.232.51,mac=00:E0:81:29:71:3D' ]
disk = [ 'file:/home/xen/51/diskimage,sda1,w', 'file:/home/xen/51/swapimage,sda2,w', 'file:/home/xen/51/homeimage,sdb1,w' ]
dhcp="off"
ip="82.149.232.51"
netmask="255.255.254.0"
gateway="82.149.232.48"
hostname= "51.xen2.ckras.com"
root = "/dev/sda1"
extra = "3"

iptables -L -n
ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 PHYSDEV match --physdev-in eth0 ACCEPT all -- 82.149.232.51 0.0.0.0/0 PHYSDEV match --physdev-in vif16.0 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 PHYSDEV match --physdev-in vif16.0 udp spt:68 dpt:67


82.149.232.51 works (dhcp) , but 82.149.232.57 not:

in s51/etc/network/interfaces:
auto eth0:1
iface eth0:1 inet static
       address 82.149.232.57
       netmask 255.255.255.0

iptables -L -n is missing this line:
ACCEPT all -- 82.149.232.57 0.0.0.0/0 PHYSDEV match --physdev-in vif16.0

xm vif-list s51
(vif (idx 0) (vif 0) (mac 00:e0:81:29:71:3d) (vifname vif19.0) (ip 82.149.232.51) (evtchn 12 4) (index 0))

from my xen0 i can ping the .57 ip, but not from extern.


how can i create it?

Frieder Kundel

btw. sorry for my bad english ;)

one command:
iptables -A FORWARD -m physdev --physdev-in vif19.0 -s 82.149.232.57 -j ACCEPT

but why doesn't xen do it auto. ?
