Hi Joseph, Eddie,
The response speed of keyboard input by web onvnc is half as slow as that of the other by vncviewer(xtightvncviewer) or gvncviwer to access the host Linux Xorg screen (screen resolution: 1920x1080) by ikvm .
The other issue is the ikvm novnc window resolution on bmc webpage <https://xxx/#kvm> is to slow to see the whole host screen. How to change it?
Do you have any ideas to improve the preformance of web novnc?
Best,
Xiuzhi
Hi Joseph,
Thanks for your suggestion. I can get the host screen now after modifying the ngnix.conf .
Best,
Xiuzhi

Hi Avi ,Joseph,
I can't get the host screen after updating openbmc source to to latest version (Oct 31 commit 7baabe48d8a2a30857994f222925505750728e39).
The error of opening the webpage https//xxxx/#kvm is :
Refused to load the image 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAgAAAAHCAYAAAA1WQxeAAAAOklEQVQYV2P8////fwYoYGRkZAQxUcRAHJA4SB2yArgYTAdMAMRH1gA2ElkRlA03DW4nThMIuoGQLwCKQ0b4DNy9fwAAAABJRU5ErkJggg==' because it violates the following Content Security Policy directive: "default-src 'self' wss: 'unsafe-eval' 'unsafe-inline'". Note that 'img-src' was not explicitly set, so 'default-src' is used as a fallback
Can you give me advice on how to modify the 0001-Implement-KVM-in-webui.patch ?

Hi Avi ,Joseph,
I checked the patches for bmc side, the rest_dbus.py on bmc was not patched sucessfully.
The files on bmc are:
/run/initramfs/ro/usr/lib/python2.7 /site-packages/obmc/wsgi/apps/rest_dbus.py
/usr/lib/python2.7/site-packages/obmc/wsgi/apps/rest_dbus.py
I patched the file on phosphor-gevent .
Now I patched the rest_dbus.py on phosphor-rest again,the file of bmc side has updated.
Now it works.
Thanks,
Xiuzhi

Hi Xiuzhi,
Can you take the patches and merge them to your environment?
Josef,
Maybe you need to give the commit or tag you are that above it you use your patches?

I think we are using different bases of the openbmc, this patch is really working on my side

We are reviewing a proposed fix to change the Content-Security-Policy directive to: script-src 'self' 'unsafe-eval' 'unsafe-inline'; object-src 'self'
See: https://gerrit.openbmc-project.xyz/#/c/openbmc/meta-ibm/+/14800/1/recipes-httpd/nginx/files/nginx.conf
For a quick workaround, remove the Content-Security-Policy directive from your nginx config file (on the BMC, typically /etc/nginx/nginx.conf) or change it to the setting mentioned above, restart the nginx service: systemctl restart nginx, and then you may need to clear your web browser's cache (for example, Firefox - Preferences - advanced - clear cache).
