[Xen-devel] [PATCH] Fix xm create command for wrong scheduler parameters

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

When I tested the xm create command with wrong scheduler parameters, 
a domain existed with the paused state. Usually, if an error occurred 
by the xm create command, the domain isn't created. 
The xm start command also has same issue. 

# xm create /xen/vm1.conf cpu_weight=99999
Using config file "/xen/vm1.conf".
Error: weight is out of range
# xm create /xen/vm2.conf cpu_cap=999
Using config file "/xen/vm2.conf".
Error: cap is out of range
# xm list
Name                                      ID   Mem VCPUs      State   Time(s)
Domain-0                                   0   491     2     r-----    594.5
vm1                                        6   256     1     --p---      0.0
vm2                                        7   256     1     --p---      0.0


This patch fixes the issue. If the xm create command fails with 
wrong scheduler parameters, it destroys the domain in the proceeding 
of xm create command.
