[Xen-users] Argh, trying to start new domU keeps crashing

I''ll paste the xend.log at the bottom.

I am using a xen/next kernel (2.6.32) from git and xen-unstable.hg

I have all the tools installed, machine boots and xm list and stuff
works, but after i went to create my new server called syslog i got
memory errors about not having enough and really nothing else useful.
This is a 4 gig machine, in the grub i set dom0_mem=524288 and in
xend-config i have dom0_min setting to 512 (is that right?) and
balloon option to yes

here is the output now

[Xen-users] Re: Argh, trying to start new domU keeps crashing

Im going to try downloading the xen/master kernel and xen-testing and
see if it works under those I guess.

So close! I have another machine working using the xen/master and
xen-3.4-testing, so hopefully it will work on this new box too. I
basically just copied all my configs over, not sure if I am just
missing something or what.

Oh also i setup a 10G lvm, oh here is my syslog.cfg. My last test i
tried with acpi = 0 and apci = 0 but didnt do anything. My previous
config was setup for paravirt, also not working.

admin = ''root''

import os, re
arch = os.uname()[4]
kernel = "/usr/lib/xen-default/boot/hvmloader"
builder=''hvm''

memory      = 512
shadow_memory = 8
vcpus       = 1
root        = ''/dev/xvda ro''
disk        = [''phy:/dev/volumes/memcache1,xvda,w'',
''file:/xen/media/debian-netinst.iso,xvdc:cdrom,r'']
boot = ''dc''
device_model = ''/usr/lib/xen/bin/qemu-dm''
vif = [ ''type=ioemu, bridge=xenbr0'' ]
apic = 0
acpi = 0
name        = ''syslog''
vfb = [''vnc=1,vnclisten=0.0.0.0,vncunused=1'']
on_poweroff = ''destroy''
on_reboot   = ''restart''
on_crash    = ''restart''

I dont understand...... I have gigs of free memory, im trying to start
a guest and only requesting 256M of memory.

Using config file "./syslog.cfg".

Im going to try downloading the xen/master kernel and xen-testing and
see if it works under those I guess.

So close! I have another machine working using the xen/master and
xen-3.4-testing, so hopefully it will work on this new box too. I
basically just copied all my configs over, not sure if I am just
missing something or what.

Oh also i setup a 10G lvm, oh here is my syslog.cfg. My last test i
tried with acpi = 0 and apci = 0 but didnt do anything. My previous
config was setup for paravirt, also not working.

admin = ''root''

import os, re
arch = os.uname()[4]
kernel = "/usr/lib/xen-default/boot/hvmloader"
builder=''hvm''

You might want to try xen/stable, which is at 2.6.32.9 and thus has many
fixes over 2.6.32.

You should check the domU console output! So configure the domU only
with a text/serial console (no vfb graphical vnc console), and then try:

xm create -f /etc/xen/<guest> -c

That should show you where the domU kernel crashes and why.
