[Xen-users] xen vm won't start (xenconsole: Could not read tty)

[Cristian Livadaru <drac3@xxxxxxxxx>]

Hi, I just installed xen 3.0.1 on Debian the only problem I have now is
to get the xen vm running.
when I try to start a vm I always get this error:

xm create -c /etc/xen/vm01-config.sxp
Using config file "/etc/xen/vm01-config.sxp".
Started domain vm01
xenconsole: Could not read tty from store: No such file or directory

What I could find searching mailinglists and forums is that this
messages is displayed when the vm crashed or didn't even start.
This seems to be ocrrect since I don't see anything in the vm logs.
I just don't know here to look further, if anybody could give me a hint
to solve this problem...

my vm config:

name="vm01"
kernel="/boot/vmlinuz-2.6.12.6-xenU"
root="/dev/hda1"
memory=128
disk =
['phy:/dev/vhostvg/baselv,hda1,w','phy:/dev/vhostvg/baseswaplv,hda2,w']

# network
vif=[ '' ]
dhcp="off"
ip="88.198.217.74"
netmask="255.255.255.248"
gateway="88.198.217.73"
hostname="vm01.lcx.at"

extra="3"


output from the xend logfile:
