[one-users] mm_sched not dispatching vm

Hi,

I just solved this problem. This was caused by the banner we configure  
by default for ssh login. When executing the command:
[one at cloudtest3 one-im]$ ssh -n localhost /tmp/one-im/one_im- 
aad4c7251b14704c02dd0646f79b7e07
Authorized users only. All activity may and will be monitored and  
reported.
HYPERVISOR=xen
TOTALCPU=200
CPUSPEED=2675
TOTALMEMORY=4184064
FREEMEMORY=524288
USEDMEMORY=3659776
USEDCPU=4
FREECPU=196
NETTX=25396
NETRX=1573171
[one at cloudtest3 one-im]$ exit

The output gets the banner included:
Authorized users only. All activity may and will be monitored and  
reported.

When I remove this banner from /etc/ssh/sshd_config and reload ssh the  
scheduler deploys the virtual machine without any problem.

Did I miss this part in the documentation, or is this not documented?  
If not, is it possible to include this in the installation  
documentation, because possibly more people encounter this issue. Or  
even better, is it possible to change the code to allow banners? Our  
internal policies require banners on host for security an liability  
reasons.

Thanks for a very flexible and great piece of software!

Regards,

Rogier
