Description of problem:
Can't run a VM after shutting it down in order to rename it, then renaming it.

Version-Release number of selected component (if applicable):
Virtual Machine Manager, version 1.3.2
libvirt - 1.2.17-13el7_2.2.x86_64
qemu-kvm-ev-2.3.0-31.el7_2.7.1.x86_64
qemu-kvm 1.5.3-105.el7_2.3.x86_64


RHEL 7.2 installed

RHEL release - 3.10.0-327.4.5.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Setup a VM with linux OS (tried with fedora 22 and rhel 7.2)
2.Shut down the VM (using shut down)
3.VM status is now Shutoff.
4.Rename the VM
5.Press Run (fails)
6.Rename the VM again to the original name with which it was created.
7.Press Run (succeeds...)

Actual results after step 5:
rror starting domain: internal error: process exited while connecting to monitor: 2016-02-16T11:58:29.173694Z qemu-kvm: -chardev socket,id=charchannel0,path=/var/lib/libvirt/qemu/channel/target/domain-fedora22/org.qemu.guest_agent.0,server,nowait: Failed to bind socket to /var/lib/libvirt/qemu/channel/target/domain-fedora22/org.qemu.guest_agent.0: No such file or directory

BTW, libvirtd status, which was nice and clean before, now contains:

These are the changed names of the VMs, and the tainted message is also received when restart is indeed performed and I believe is caused by qemu intervening with libvirt, and has no real baring on the use case. 

Expected results:
Successfully restarting the VM.

Let me know if any additional info is needed.
And if you have a workaround to enable VM renaming I would greatly appreciate it.

I did not encounter this behaviour in previous setups, therefore tagged as a regression. I did, for sure, changed the name of a VM before and could successfuly restart it.
