Description of problem:
I tried to use virt-manager to create a new VM with storage located on NFS.  I also customized the settings (to select vga instead of cirrus for the video adapter).  The first attempt failed, because of SELinux, so I backed up a screen, fixed the selinux settings, then went forward again, but my customizations were lost and I had to repeat them.

Version-Release number of selected component (if applicable):
virt-manager-0.8.4-7.el6.noarch


How reproducible:
always

Steps to Reproduce:
1. as root, run setsebool virt_use_nfs 0
2. Start virt-manager, and connect to a host
3. Start to create a new domain
4. On step 4, select managed storage, and select a disk image on an NFS path
5. On step 5, check Customize before hitting finish
6. Make a customization, such as changing video to vga, and apply, then hit the check mark to start the install
7. The install will fail because the image can't be accessed and kick you back to step 5
8. run setsebool virt_use_nfs 1
9. Again, check customize, and notice that the customization was lost
  
Actual results:
customization is lost every time that creation fails and you get kicked back to step 5

Expected results:
customization should be remembered - if creation fails, and I correct the root cause of the failure, then continuing from step 5 should remember what I already changed
