Hi, the -s/-a argument pair are primarily used for our internal inmate demos with "jailhouse cell load", and not for "jailhouse cell linux".
You could, e.g., use: jailhouse cell load your-cell apic-demo.bin -s "con-base=0x3f8 con-type=PIO" -a 0x100 Look at the position of the quotes. This will redirect output of apic-demo to the HV console, if it's permitted to. The -c parameter for "jailhouse cell linux" appends cmdline arguments to the linux kernel, not configuration parameters for the loader. To enable the console on x86, you probably have to do sth. like jailhouse cell linux cell image -i initrd -c "console=jailhouse" (or console=jailhouse0, not sure, only used it on ARM via device trees).
