Hi Thaju/Lei,
Check journal (journalctl -f) while you're testing KVM if there is any
suspicious error. In normal opration, you should see logs like below:

Also, try these two patches. I added one more patch.
https://gerrit.openbmc-project.xyz/c/openbmc/obmc-ikvm/+/19392
https://gerrit.openbmc-project.xyz/c/openbmc/obmc-ikvm/+/19433
If it doesn't make help, try external connection using Tight VNC viewer.
Currently, external connection is disabled by libvncserver's listening
ip setting so apply below patch if you are going to enable external
connection.
In obmc-ikvm package:
-----------------------
diff --git a/ikvm_server.cpp b/ikvm_server.cpp
index 35310da292be..b7bd5344ed0d 100644
--- a/ikvm_server.cpp
+++ b/ikvm_server.cpp
@@ -44,7 +44,7 @@ Server::Server(const Args& args, Input& i, Video& v) :
server->cursor->xhot = 1;
server->cursor->yhot = 1;
- rfbStringToAddr(&ip[0], &server->listenInterface);
+ //rfbStringToAddr(&ip[0], &server->listenInterface);
rfbInitServer(server);
-------------------------
Make sure that it's just for test purpose. We intentionally disabled
external connection because of security issue. Also, you might need to
use Tight VNC viewer only. I checked that other VNC viewers don't
support tight encoding properly.

Jae
