Description of problem:

configure netconsole with user define port(30000), rhev-hypervisor status is up on rhev-m side, but although port 30000 not used by any app on rhevm side, rhevm still keep listen on the default port(25285), didn't aware the change(should listen on udp & port is 30000), so there is no printk info from rhev-hypervisor, vdsm/vdsm-reg should notify rhevm the change, detail you could see below, and the attachment for netstat ouput on rhevm side, 

as this is the communication  between rhev-hypervisor & rhev-m, so i set the component to vdsm



/etc/vdsm-reg/vdsm-reg.conf
