[Xen-devel] [PATCH] Fix xm create/start with sedf scheduler

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

When I tested the Xen with the sedf scheduler, I was not able to 
create a VM. Error messages and xend.log are as follows. 

xm create command:
 # xm create /xen/vm1.conf 
 Using config file "/xen/vm1.conf".
 Error: (22, 'Invalid argument')

 [2007-01-29 17:01:22 5129] ERROR (XendDomain:1363) (22, 'Invalid argument')
 Traceback (most recent call last):
   File "//usr/lib/python/xen/xend/XendDomain.py", line 1361, in 
domain_sched_credit_set
     return xc.sched_credit_domain_set(dominfo.getDomid(), weight, cap)
 Error: (22, 'Invalid argument')

xm start command:
 # xm new /xen/vm1.conf 
 Using config file "/xen/vm1.conf".
 # xm list

I fixed the issues. If the Xen is running with the sedf scheduler, 
the following functions do not call the domain_sched_credit_set(). 
 - domain_create()
 - domain_create_from_dict()
 - domain_start()
