Hey Daniel, I had tried to setup the VM, and opened an issue on the camkes-arm-vm repo - https://github.com/SEL4PROJ/camkes-arm-vm/issues/3
The VChan is quite outdated. My issue should summarize what I had to do in order to get the system to compile.

I got couple questions how you can give me some advices. 1. I saw the camkes_vchan_con_t structure in the helloworld components (camkes-arm-vm), but I could not find the implementation for vchan_con_new_connection(), vchan_con_rem_connection(), etc. Are those autogenerated by camkes? If so how it is generated? static camkes_vchan_con_t con = { .connect = &vchan_con_new_connection, .disconnect = &vchan_con_rem_connection, .get_buf = &vchan_con_get_buf, .status = &vchan_con_status, .alert = &vchan_con_ping, .wait = &vevent_wait, .poll = &vevent_poll, .dest_dom_number = 0, .source_dom_number = 50, }; 2. I tried to compile the Vchan support and demo helloworld components for odroid-xu. But the compile shows error due to the VM.h file (camkes-arm-vm/projects/vm/components/VM/src/cmks_vchan_vm.c:23) cannot be found. How can I generate the VM.h file? Thanks a lot! Best Regards -Daniel Wang
