Bug 749763

Description of problem:
In virt-v2v manual,there is description of -ic parameter as:
-ic URI
Specifies the connection to use when using the libvirt input method. If omitted, this defaults to
qemu:///system when virt-v2v runs as root, or qemu:///session when virt-v2v runs as a regular user

When use virt-v2v as regular user,the -ic parameter descripted in virt-v2v manual doesn't match the actual behaviour

Version-Release number of selected component (if applicable):
virt-v2v-0.8.3-5.el6.x86_64
libguestfs-1.7.17-26.el6.x86_64
libvirt-0.9.4-20.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1.Make sure there are two pools created by non-root user,and there is a guest in one pool.
[tzheng@tzheng-linux ~]$ virsh pool-list 
Name                 State      Autostart 
-----------------------------------------
test-pool            active     no        
tzheng-pool          active     no 

[tzheng@tzheng-linux ~]$ virsh list --all
 Id Name                 State
----------------------------------
  - esx4.0-rhel5.6-x86_64 shut off

2.Use virt-v2v to convert the guest to another pool as non-root user.
[tzheng@tzheng-linux ~]$ virt-v2v -os test-pool -on test esx4.0-rhel5.6-x86_64 
virt-v2v: Failed to connect to qemu:///system: libvirt error code: 45, message: authentication failed: authentication failed

When I add "-ic qemu:///session" to the command,it will convert successfully.
[tzheng@tzheng-linux ~]$ virt-v2v -ic qemu:///session -os test-pool -on test esx4.0-rhel5.6-x86_64 
ESX4.0-rhel5u6-64b_ESX4.0-rhel5u6-64b: 100% [=====================================================================]D 0h03m04s
virt-v2v: test configured with virtio drivers.


Actual results:
If omit the -ic parameter,the error message showed as:Failed to connect to qemu:///system.

Expected results:
Since in virt-v2v manual,if omit the -ic parameter as regular user,it defaults to qemu:///session,so the error message showed should be:Failed to connect to qemu:///session
