[ovirt-users] strange error when editing multiple disks

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: vm1: - Cannot edit Virtual Disk. At least one of the VMs is not down. " ? 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 Gianluca
