nit: i think legibility of this would be improved by doing this instead:

let pbsChangeDetectionModeSelector = null;
if (me.vmtype === 'lxc') {
    pbsChangeDetectionModeSelector = Ext.create({
        ...
    })
}

it shouldn't be too much longer, but having a ternary operate span ten
lines of code is a bit much :)
