Description of problem:
Edit VM with some custom properties, for example: viodiskcache, writethrogh.
and press OK.
Edit VM again, do not show these settings.
Version-Release number of selected component (if applicable):
custom properties settings should be seen, on next Edit VM.
this seems to be some UI issue with presenting the value,
i verified it is saved in the db (using ui), and value returns ok with rest
verified in vt3
oVirt 3.5 has been released and should include the fix for this issue.
