[Xen-users] Xend has probably crashed! Invalid or missing HTTP status code.

[Michael Wineland <mike@xxxxxxxxxxx>]

I have Xen3 installed on Ubuntu 6.10 server,
$ sudo xm list
Name                                      ID Mem(MiB) VCPUs State   Time(s)
Domain-0                                   0      250     8 r-----    748.2

but whenever i try to create a new domain with anything listed for 
kernel at all, i get this:
$ sudo xm create domu1
Using config file "domu1".
Xend has probably crashed!  Invalid or missing HTTP status code.

this is the config i am trying to use:
$ sudo xm create domu1 -n
Using config file "domu1".
(vm
   (name domu1)
   (memory 512)
   (vcpus 1)
   (image (linux (kernel /etc/xen/fdsfsdf) (root '/dev/sda6 ro') (args 4)))
   (device (vbd (uname phy:sda6) (dev sda1) (mode w)))
   (device (vbd (uname phy:/dev/sda7) (dev sda2) (mode w)))
   (device (vif (bridge xenbr1)))
)


I'm probably dont have it set up right since this is the first time i am 
doing this, but i am trying to use the actual partition sda6 as the 
primary partition for the new domain and sda7 as the swap partition, but 
even if i make a completely blank config file and add anything for 
kernel, it gives that same error, i'm not sure how to proceed

btw I did debootstrap from the ubuntu server cd to sda6, if that matters 
any, and heres the actual config file:

# where INSTANCE indicates the instance number of the TPM the VM
# should be talking to and DOM provides the domain where the backend
# is located.
# Note that no two virtual machines should try to connect to the same
# TPM instance. The handling of all TPM instances does require
# some management effort in so far that VM configration files (and thus
# a VM) should be associated with a TPM instance throughout the lifetime
# of the VM / VM configuration file. The instance number must be
# greater or equal to 1.

# variables used by custom rc scripts (e.g. VMID=, usr= ).

# Set if you want dhcp to allocate the IP address.

# Sets runlevel 4.

#----------------------------------------------------------------------------
# Configure the behaviour when a domain exits.  There are three 'reasons'
# for a domain to stop: poweroff, reboot, and crash.  For each of these you
# may specify:
#
#   "destroy",        meaning that the domain is cleaned up as normal;
#   "restart",        meaning that a new domain is started in place of 
the old
#                     one;
#   "preserve",       meaning that no clean-up is done until the domain is
#                     manually destroyed (using xm destroy, for example); or
#   "rename-restart", meaning that the old domain is not cleaned up, but is
#                     renamed and a new domain started in its place.
#
# The default is
#
#   on_poweroff = 'destroy'
#   on_reboot   = 'restart'
#   on_crash    = 'restart'
#
# For backwards compatibility we also support the deprecated option restart
#
# restart = 'onreboot' means on_poweroff = 'destroy'
#                            on_reboot   = 'restart'
