Hi Jae/Xiuzhi,

I have tried enabling KVM as mentioned in the mail thread. But unable to
get the video in the web. Also tried using vnc viewer, but connection
refused.

I see the following:

# obmc-ikvm -v /dev/video0 -f 10 -k /dev/hidg0 -p /dev/hidg1
26/02/2019 09:41:04 Unable to establish connection with systemd socket

26/02/2019 09:41:04 Listening for VNC connections on TCP6 port 5900
26/02/2019 09:42:17 Got connection from client 127.0.0.1
26/02/2019 09:42:17   other clients:
26/02/2019 09:42:17 Normal socket connection

SERVICE_FILE = "start-ipkvm.service"
SYSTEMD_PACKAGES = "${PN}"

What am I doing wrong here?
Do we need to set "-DBMCWEB_ENABLE_KVM=ON" in bmcweb?

Regards,
Thaj
