Hi, Thank you all for your help. Here is a very long email, with all
the info I thought might be interesting.
@Stephan: I use different lvms for each VM.
@Felix, yes I am using a KimsufiXL server.
@Jim: mac address in vif? I thought it was an IPv4 address I had to
put. What should I put then? Any figures?
Here are my config files:
node01:
--------------------------------------------------------------
# -*- mode: python; -*-
kernel="/boot/domU_32/vmlinuz-2.6.21-xxxx-xenU-ipv4-32"
memory = "256"
maxmem = "512"
name = "node01"
vcpus=1
interface=eth0
dhcp="off"
vif = [ 'ip=10.0.0.1' ] # replace with DomU's IP
ip = "10.0.0.1"
gateway= "10.0.0.128" # Dom0
netmask = "255.255.255.0"
# example for LVM or partition
disk = [ 'phy:/dev/mapper/xenvg-node01,/dev/hda1,w',
'phy:/dev/mapper/xenvg-node01--swap,hda2,w' ]
# example for image file
#disk = [ 'file:xen/xenvg-node0001.img,hda1,w',
'file:/xen/xenvg-node0001-swap.img,hda2,w' ]
# This uses environment variables XAUTHORITY and DISPLAY. You
# can override that:
# vfb = [ 'type=sdl,xauthority=/home/bozo/.Xauthority,display=:1' ]
#
# To create one using the VNC backend and sensible defaults:
vfb = [ 'type=vnc' ]
# The backend listens on 127.0.0.1 port 5900+N by default, where N is
# the domain ID. You can override both address and N:
#
# Or you can bind the first unused port above 5900:
# vfb = [ 'type=vnc,vnclisten=0.0.0.0,vnunused=1' ]
# You can override the password:
# vfb = [ 'type=vnc,vncpasswd=MYPASSWD' ]
# Set the hostname.
#hostname= "node%d" % vmid
# Set root device.
root = "/dev/hda1"
# Sets runlevel 2.
#extra = "2"
extra='console=xvc0 xencons=xvc0'
#sdl=0
#vnc=0
nographics=0
--------------------------------------------------------------
node02:
--------------------------------------------------------------
# -*- mode: python; -*-
kernel="/boot/domU_64/vmlinuz-2.6.21-xxxx-xenU-ipv4-64"
memory = "256"
maxmem = "512"
name = "node02"
vcpus=1
#interface=eth0
dhcp="off"
vif = [ 'ip=10.0.0.2' ] # replace with DomU's IP
ip = "10.0.0.2"
gateway= "10.0.0.128" # Dom0
netmask = "255.255.255.0"
# example for LVM or partition
disk = [ 'phy:/dev/mapper/xenvg-node02,/dev/hda1,w',
'phy:/dev/mapper/xenvg-node02--swap,hda2,w' ]
# example for image file
#disk = [ 'file:xen/xenvg-node0001.img,hda1,w',
'file:/xen/xenvg-node0001-swap.img,hda2,w' ]
# This uses environment variables XAUTHORITY and DISPLAY. You

root = "/dev/hda1"
# Sets runlevel 2.
#extra = "2"
extra='console=xvc0 xencons=xvc0'
#sdl=0
#vnc=0
nographics=0
--------------------------------------------------------------
In node02 configuration file, if I specify interface=eth0, I get the
following error message: "Error: name 'eth0' is not defined". Also for
node02 I have tested with a 32bits Debian release and I had the same
problem.
Now here is the log file of a working VM:
--------------------------------------------------------------
Watching /local/domain/0/device-model/56/logdirty/next-active
Watching /local/domain/0/device-model/56/command
shift keysym 003e keycode 86

xs_read(): vncpasswd get error.

--------------------------------------------------------------
And the log file of a VM that doesn't start and uses 100% cpu in xentop:
--------------------------------------------------------------
Watching /local/domain/0/device-model/57/logdirty/next-active
Watching /local/domain/0/device-model/57/command

xs_read(): vncpasswd get error.
/vm/a318301b-7221-8082-f302-4f2e4bec156b/vncpasswd.
bind() failed
--------------------------------------------------------------
And here is the ifconfig output on Dom0: (I have removed some data
that didn't seem relevant)
--------------------------------------------------------------
# ifconfig

inet addr:10.0.0.129 Bcast:0.0.0.0 Mask:255.255.255.255
--------------------------------------------------------------
I have noticed that when only 1 VM is running I only have 1 vifxx.0
When I start a second VM (although it hangs) I see a second vif that
appears, is that normal?
