Does obmc-ikvm work with bmcweb?

[Thaju]

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 TCP port 5900
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

# dmesg | grep video

obmc-ikvm recipe:

SUMMARY = "obmc kvm application"
DESCRIPTION = "Interfaces video device and USB HID device on BMC"

FILESEXTRAPATHS_append := ":${THISDIR}/${PN}"

inherit systemd
inherit obmc-phosphor-systemd

SRCREV = "2bc661d34abd1fda92a9d2b256ed88ca0e90d09a"

DEPENDS += "autoconf-archive"
DEPENDS += "libvncserver"
DEPENDS += "sdbusplus"
DEPENDS += "sdeventplus"
DEPENDS += "phosphor-logging"
DEPENDS += "phosphor-dbus-interfaces"
DEPENDS += "systemd"

S = "${WORKDIR}/git"

SERVICE_FILE = "start-ipkvm.service"
SYSTEMD_PACKAGES = "${PN}"
SYSTEMD_SERVICE_${PN} += "${SERVICE_FILE}"
SYSTEMD_DEFAULT_TARGET ?= "${SYSTEMD_DEFAULT_TARGET}"

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

Regards,
Thaj
