Xen users - Dec 2007 - xm create - Xend has probably crashed! Invalid or missing HTTP status code.

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

Is your xend running?  That would be the first place I would look.

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

Anything interesting in /var/log/xen/xend.log or /var/log/xen/xend-debug.log?

Dave: Skateboards have wheels.

I should never expect an fc6 of f7 to work nicely with 64MB of memory.  
Can u please set the "maxmem = <something greater than 64>" in
the guest
configuration file and test after that?

Thanks for the reply. We modified the config file as follows:
kernel = "/boot/vmlinuz-2.6.20-2943.fc7xen"
memory = 256
name = "fedora.fc6"
vif = [ '''' ]
dhcp = "dhcp"
disk = [''file:/srv/xen/fedora.fc6.img,sda1,w'']
root = "/dev/sda1 ro"

But running the same config file on an earlier xen version works (xm create
shows domain created). Only when running on xen-3.2-unstable.gz as the
hypervisor this error comes.

I have tried both the -xen and -xen0 and -xenU versions for dom0 and domU,
which compiled along with xen-3.2-unstable.

Is this next bit where you create your new domain?

OK.

The fact that Xend died here due to Signal 11 (segfault) is quite worrying in 
itself.  It juggests that some kind of bug has just happened...  weird.

I guess that suggests that whatever bit you skipped above might have had 
something to do with it.  Sorry, it''s not the direct cause of the error
you''re seeing, so I understand why you skipped it.  But I suspect it
has
something to do with the root cause.

For some reason, maxmem_kb is 0 in the domain it''s trying to recreate,
so it
seems not to have any memory.  It also says the domain is paused...  Perhaps 
Xend crashed with signal 11 part way through creating a domain for you - is 
that a possibility?

Xend seems to have got itself into a funny state, possibly due to the earlier 
crash.  Ideally, it should probably handle this sort of thing better, though.

Are you still having this problem?  Have you tried updating your pull of 
xen-unstable?

And in your setup, have you enabled any particular security policy at all?  
I''m afraid I don''t understand the security policies very well,
so this is
slightly unfamiliar territory for me.

Cheers,
Mark
