Before doing that, if using network-bridge, could you try looking / tweaking the forward delay, max age and hello settings of the bridge. I'd at least eliminate it as a cause before re-installing. Its not going to hurt you to go with the last official Xen release (in either series), but I don't think its the cause of your issue. Cheers, --Tim

set static ip in config file

Hi all,
I have create a centos in domU using "xm create test.cfg". The
content of test.cfg print as below:
kernel = "/usr/lib/xen/boot/hvmloader"
builder = 'hvm'
name = "test"
memory = 512
disk = [ 'file:/root/xen/ubuntu-9.10-desktop-i386.iso,hdc:cdrom,r',
'file:/srv/xen/mailserver.img,hda,w' ]
boot = "d"
vif = ['ip=192.168.1.100,bridge=eth1']
dhcp = "off"
vcpus=1
on_reboot = 'restart'
on_crash = 'restart'
sdl=0
vnc=1
vnclisten="0.0.0.0"
vncpasswd='password'
stdvga=0
serial='pty'
usbdevice='tablet'
I set static ip==192.168.1.100 in vif, but the centos in domU still
use the dhcp. To be noted here, I can set static ip in centos when I
connect to the console of domU.
Who can tell me why and how to set static ip in config file.
Thanks a lot.

Short answer: that's the way it works. There are cases when setting IP in domU config file can be used (for example when deploying custom bridge+iptables script), but that's kinda complicated. The short version is that using the default setup the setting is not used and has no effect on actual domU IP address. -- -- Fajar

Manage tape on guest win2k3

Hi Everybody,
I have a problem with my magnetic tape drive, I control the tape with BackupExec on my guest win2k3.
BackupExec see it right my tape drive but for him the tape is in use...
I think it's my dom0 use it, because i can pilot the tape drive with the command "mt" on dom0...
So for me i need to hide the tape to boot ... but this line in grub have no impact :
module /boot/vmlinuz-2.6.18.8-xen-amd64 root=/dev/sda1 ro console=tty0 scsiback.permissive scsiback.hide=(6:0:6:0)
If you have an idea on this subject, I listen you !!
Thanks for your answer in advance.
Rémi
Conf:
Debian lenny, kernel 2.6.18-8x86_64-xen, xen 3.4.2 (xenbits)

hi, Thanks very much. I have many VMs to deploy and have to set static ip for each VM. So I want to try some methods. Can you send me some cases such as deploying custom bridge+iptables script?

It's not really how to DEPLOY, but how to LIMIT which IP address a domU can use with the help of ebtables.

In addition to that the CentOS kernel is not compiled with CONFIG_IP_PNP so having a DomU with
the ip set in the config file will never work. It will if you recompile the kernel or use a different OS like Debian in the DomU.
The CentOS kernel does pay attention to the MAC address assigned in the DomU config file though so you
can set up a DHCP server with that MAC in it and it will assign the IP you want.
