Description of problem:

"virsh start" succeeds even if an invalid guest name is configured to an xml
file. Assume an invalid "#" is specified as a domain name, "virsh start" should report an error message like "invalid domain name", but the guest is started successfully without any errors.

# is an illegal name. When I try to name a guest as # via virt-manager, it says.

"Invalid system name, Guest name can only contain alphanumeric, '-', '.' or '-'  characters."

So virsh would report an error message and should not start the guest.

Version-Release number of selected component:

Red Hat Enterprise Linux Version Number: 6
Release Number: snapshot13
Architecture: x86_64
Kernel Version: kernel-2.6.32-70.el6.x86_64
Related Package Version: libvirt-client-0.8.1-27.el6.x86_64

How reproducible:

Always.

Steps to Reproduce:
1. Edit the xml file and change the name of the guest to #

<domain type='kvm'>
  <name>#</name>
  <uuid>92ae9226-70ca-d0e8-ab41-2ebfe2edbf3c</uuid>
  <memory>1048576</memory>

2.start the guest

# virsh start \#
Domain # started 

# virsh dumpxml \#
<domain type='kvm' id='1'>
  <name>#</name>
  <uuid>92ae9226-70ca-d0e8-ab41-2ebfe2edbf3c</uuid>
  <memory>1048576</memory>
  <currentMemory>1048576</currentMemory>

 # virsh list
 Id Name                 State
----------------------------------
  1 #                    running
 
Actual results:

virsh is able to start the guest if an invalid name is specified in the guest xml file.

Expected results:

virsh should report an error and should not start the guest.
