I'm noticing this on 4.3.8 and I don't have understood exactly the raising condition, if UI based or what

At first I thought it was the bootable flag, but it is not, apparently

vm1 powered on with two disks

I select the VM then Disks subtab

select line of second disk --> edit --> OK

All goes well

Then, remaining in the same Disks subtab window  I select the line of the first disk --> Edit --> OK

And now I get the error window:

"

Error while executing action:

"

?

Then I go and select another powered on VM, vm2, with only one disk, the one with bootable flag, and I'm able to edit it successfully.

Then I come back and select vm1 and Disks subtab, select again the first line of the boot disk --> Edit --> OK

and I'm able to edit with success..... but eg if I want to modify both alias and description fields I have to do one at a time, otherwise if in the same window I try to modify both and then press OK I still get the error message above.

Can anyone verify/test? I was able to reproduce on bot oVirt 4.3.8 and RHV 4.3.8
