Tksï

I run pv guest ï When I create pv guest by xen-create-image command,the vif can up success.

But when I create guest system through the following the script of the way to create.( In fact is to copy a guest system)

#!/bin/bash

 

# $1 is Âipaddr

if [ -z $1 ];then

ÂÂÂÂÂÂÂ echo "Usage:$0 ip_addr"

ÂÂÂÂÂÂÂ exit 0

fi

# get random string

MATRIX="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"

LENGTH="2"

while [ "${n:=1}" -le "$LENGTH" ]

do

ÂÂÂÂÂÂÂ PASS="$PASS${MATRIX:$(($RANDOM%${#MATRIX})):1}"

ÂÂÂÂÂÂÂ let n+=1

done

echo "$PASS"

cp templates.cfg $1.cfg

# set mac

sed -i "s/TEMP/$PASS/g" $1.cfg

# set hostname

sed -i "s/HOSTNAME/$1/g" $1.cfg

# set ipaddr

sed -i "s/IPADDR/$1/g" $1.cfg

 

#

## create disk iso and swap file

#

 

mkdir -p /data/xen/domains/$1

dd if=/dev/zero of=/data/xen/domains/$1/disk.img bs=1 count=1 seek=20G

dd if=/dev/zero of=/data/xen/domains/$1/swap.img bs=1M count=1024

mkfs.ext4 /data/xen/domains/$1/disk.img

sleep 2

cd /data/xen/domains/$1

mount -o loop disk.img /mnt

tar -zxSf /data/xen/domains/templates_10.04/ubuntu_10.04.tgz -C /mnt/

sleep 2

sed -i "s/10.10.10.231/$1/g" /mnt/etc/network/interfaces

sleep 2

umount /mnt

 

#

## start vps $1

#

xm create -c $1.cfg

ubuntu_10.04.tgz is a os iso file.

Hiï

 

in the ubuntu 12.04 ,i installed the xen dom0 success.

In the startup xen guest, the guest system can be the normal starting, but guest system vif interface does not exist.

View dmesg log shows:

[2062.382385] device vif9.0 entered promiscuous mode

[2062.387698] ADDRCONF (NETDEV_UP) : vif9.0: link is not ready

[2072.221544] vif8.0: no IPv6 routers present

[2076.808353] xen-blkback: ring-ref 8, event-channel 9, protocol 1 (x86_64-abi)

[2076.847384] xen-blkback: ring-ref 9, event-channel 10, protocol 1 (x86_64-abi)

[2076.856078] eth1: port 4 (vif9.0) entering disabled state

[2076.856268] eth1: port 4 (vif9.0) entering disabled state

 

this  vif interfaces that the line is disabled.

 

And the normal vif startup information  is:

[2035.861524] ADDRCONF (NETDEV_UP) : vif7.0: link is not ready

[2048.585999] xen-blkback: ring-ref 8, event-channel 9, protocol 1 (x86_64-abi)

[2048.629885] xen-blkback: ring-ref 9, event-channel 10, protocol 1 (x86_64-abi)

[2048.648746] ADDRCONF (NETDEV_CHANGE) : vif7.0: link becomes ready

[2048.648801] eth1: port 2 (vif7.0) entering forwarding state

[2048.648806] eth1: port 2 (vif7.0) entering forwarding state

 

why the vif interfaces disabled?

 

what's wrong ?

how can I do ?

Hello,

it would be useful to know if you run a HVM or PV guest and how your configuration look like. I don't have issues with Xen on Ubuntu 12.04 and Debian. The only case where I had problems was when the vif option in the configuration file of a HVM has the option type=ioemu. There it happened that the vif interface couldn't be setup correct or stopped after a while.

Best Regards
