Description of problem:
VMs cloned with 'virt-clone' can't be started normally - have to edit their XML first.

Version-Release number of selected component (if applicable):
libvirt-1.2.17-13.el7_2.5.x86_64
virt-manager-common-1.2.1-8.el7.noarch

How reproducible:
100%

Steps to Reproduce:
1. Shutdown the original VM
2. As root, type "virt-clone --original originalvm --name clonedvm --file /var/lib/libvirt/images/clonedvm.qcow2" [1]
3. As root, type "virsh start clonedvm" [2]

Actual results:

[1]

Allocating 'clonedvm.qcow2'                                |  40 GB     00:02

Clone 'clonedvm' created successfully.

Expected results:

[2]

Domain clonedvm started


Additional info:
In element "domain => devices => channel[unix]" of the cloned VM's XML:

    <channel type='unix'>
      <source mode='bind' path='/var/lib/libvirt/qemu/channel/target/domain-originalvm/org.qemu.guest_agent.0'/>
      <target type='virtio' name='org.qemu.guest_agent.0'/>
      <address type='virtio-serial' controller='0' bus='0' port='1'/>
    </channel>

Attribute "path" of element "source" still uses the same value as the old VM. After changing the value to:

      <source mode='bind' path='/var/lib/libvirt/qemu/channel/target/domain-clonedvm/org.qemu.guest_agent.0'/>

The cloned VM started normally.
