Porting Xen in raspberry pi4B

[Vipul Suneja <vsuneja63@xxxxxxxxx>]

Hi,

Thanks!

I have ported xen minimal image as DOM0 & custom wayland GUI based image as DOMU in raspberry pi4B. I am trying to make GUI display up for guest machine. I tried using sdl, included below line in guest.conf file

vfb= [ 'sdl=1' ]

But it is throwing below error:

root@raspberrypi4-64:~/guest1# xl create -c guest1.cfg
Parsing config from guest1.cfg
libxl: error: libxl_qmp.c:1400:qmp_ev_fd_callback: Domain 3:error on QMP socket: Connection reset by peer

libxl: error: libxl_domain.c:1064:domain_destroy_cb: Domain 3:Destruction of domain failed

Another way is VNC, i could install tigervnc in DOM0 but same i couldn't in guest machine because it doesn't support x11(supports wayland only). I am completely blocked here, Need your support to enable the display up.

Any alternative of VNC which could work in both x11 & wayland supported images?

Any input on VNC, SDL or any other way to proceed on this? Looking forward to hearing from you.
