UI log
The issue is that the vm_dynamic.vm_fqdn can be null or empty string. If the vm_fqdn is null, this subtab starts to throw exceptions. You don't even need to press remove, it is enough to wait long enough and the tab will be flood by exceptions.

What's the workaround? > Is that a regression? It is not a regression, it has been this way for a long time. You will have nulls there after you turn the VM off (e.g. the ResourceManager.resetVmAttributes() is executed clearing the VM up). You will get empty values when you just create a VM because it is created by default with empty values. As a followup we may consider unifying this, but most of the code already handles both null and empty values in fqdn, the exception is SubTabNetworkVmView. > > > If the vm_fqdn is null, this subtab starts to throw exceptions.

No UI error on both, Cancel and OK. verified in ovirt-engine-webadmin-portal-4.1.3-0.1.el7.noarch |
