Thus, we have implemented an SMC that prints a character via the LOG session of the secure VMM. Then, stub-drivers for the early-printk back-end as well as for the back-end of the console of the guest Linux were implemented. Now all serial output of the VM goes through the VMM and the UART can be protected. As a result, the guest stays alive longer but it still doesn't finish its initialization."}}
