Description of problem:
After updated device with connected parameter "fail", guest's xml changed
Version-Release number of selected component (if applicable):
libvirt-0.10.0-0rc1.el6.x86_64
How reproducible:
100%
Steps to Reproduce:
1.Edit graphics element of guest's xml like this:
#virsh dumpxml test --security-info
<graphics type='spice' autoport='yes' listen='0.0.0.0' passwd= 'aaabbb' connected= 'disconnect'>
<listen type='address' address='0.0.0.0'/>
</graphics>
2.Start the guest
#virsh start test
3.Prepare a xml file to update device like this:
#cat spice-new.xml
<graphics type='spice' port='5900' tlsPort='5901' autoport='yes' listen='0.0.0.0' passwd= 'cccddd' connected= 'fail'/>
4.Open a virt-viewer window and enter the password
#virt-viewer test
password "aaabbb" works.
5.Update device with the xml file and there will be errors
#virsh update-device test spice-new.xml
error: Failed to update device from spice-new.xml
error: internal error unable to execute QEMU command '__com.redhat_set_password': Could not set password
6.Check the guest's xml
#virsh dumpxml test --security-info
<graphics type='spice' port='5900' autoport='yes' listen='0.0.0.0' passwd= 'cccddd' connected= 'fail'>
<listen type='address' address='0.0.0.0'/>
</graphics>
7.Close the virt-viewer window and reopen it
#virt-viewer test
password "aaabbb" still works not "cccddd".
Actual results:
At step 6, the guest's xml changed.
Expected results:
At step 6, the guest's xml shouldn't change.

qemu: Don't update graphic definitions on password change failure
When the password change failed we updated the graphic definition
anyways, which is not desired.
