I have the same issue.
ikvm was on the Firmware ver A03 1.0.1, I updated the CMC Firmware from 3.0.3 to 4.5 (this works).After CMC update Firmware of ikvm "disappears".
I try to update ikvm Firmware (webgui and Telnet) , but it doesn´t works.
CMC-protocol Shows timeout error. Firmware is located on the same network
Thanks in advance
