To make things more clearer,
------------------------------------------
Hi,

We downloaded  xen-3.2 unstable.
hg clone http://xenbits.xensource.com/xen-unstable.hg

We made changes to Config.mk to enable XSM with sHype
XSM_ENABLE ?= y
FLASK_ENABLE ?= n
ACM_SECURITY ?= y

We compiled with:

make world
make install
and changed grub entries appropriately.

We booted dom0 and then tried to create a domU:


[root@xxxx xxxx]# xm create /etc/xen/cfg
Using config file "/etc/xen/cfg".
Xend has probably crashed!  Invalid or missing HTTP status code.

We tried the same by using an earlier stable version of xen and the cfg worked. Hence, the cfg file is correct.

/etc/xen/cfg:
kernel = '/boot/vmlinuz-2.6.20-2943.fc7xen'
memory = 64
name = "domu"
vif = [ '' ]
disk = ['file:/srv/xen/fedora.fc6.img,sda1,w']
root = '/dev/sda1'
extra = "ro selinux=0 3"

Is this a known problem with xen-3.2 unstable? Or are we missing some step (some configuration)?

Thanks.
Hayawardh

Is your xend running?  That would be the first place I would look.
When I do xend stop and run xm list, it says xend is not running.
  When I do xend start and run xm list, it gives the output mentioned above.
  However xend start|stop|status|restart does not print anything on the console.
  When I do ps -A | grep python, it shows few processes (which are xend).

Hi,

I have compiled xen-unstable (using hg clone http://xenbits.xensource.com/xen-unstable.hg).

I have successfully booted into the dom0 kernel.

output of xm list:
Name                                      ID   Mem VCPUs      State   Time(s)
Domain-0                                   0   932     1     r-----    591.2

But whenever I xm create, I get:

# xm create /etc/xen/domu1
Using config file "/etc/xen/domu1".
Xend has probably crashed!  Invalid or missing HTTP status code.

My file is:

/etc/xen/domu1:

kernel = '/boot/vmlinuz- 2.6.18.8-xenU'
vif = [ '' ]
disk = ['file:/srv/xen/fedora.fc6.img,sda1,w']
root = '/dev/sda1 ro'

What could be wrong?

Thanks.
Hayawardh
