Description of problem:
When I'm trying to change name of the existing VM with UEFI I got this traceback:

Error apply changes: Requested operation is not valid: cannot delete inactive domain with nvram

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/details.py", line 1948, in config_apply

--------------------
There is another issue. When I tried to reproduce this I could create new VM (name generic-2) and without installation rename it (to jk_efi) but when I removed this VM and create another with the generic-2 name I can't connect to this machine. VirtManager shows me generic-2 name and when I tried to opened it opens jk_efi. I do not renamed this machine only the deleted one.

I got this traceback:

Error launching details: Domain not found: no domain with matching uuid '51f4bf86-58f9-4ca9-ae25-f07068222415' (jk_efi)

Version-Release number of selected component (if applicable):
1.2.1

How reproducible:
The second always.

Steps to Reproduce:
1. Create VM with "generic" name and as UEFI
2. Shutdown the machine
3. Rename the "generic" machine to "efi"
4. Delete the renamed VM "efi"
5. Create new VM in the same way as 1. (name "generic", UEFI)
6. Double click on this VM

Actual results:
Can't open "efi" VM. (Domain not found: no domain with matching uuid...)

Expected results:
Open new "generic" VM.
