Hi Marcin
  I cloud not find uefi mode cloud image in ubuntu bionic.  Instead, use the image bionic-server-cloudimg-amd64.img with metadata "hw_firmware_type: uefi"
However, console shows no screen.
  Besides, neither creating a CentOS image with console available isn't work.

  GRUB_CMDLINE_LINUX = "... console=tty0 console=ttyS0,115200n8"
  Cloud you please provide some suggestions how to implement console input/output with uefi mode os. 
  My appreciation~ 

Hi. After launch an UEFI mode instance in OpenStack, the console screen show the message  “Guest has no initialized the displayed (yet) "  
 Engage your help, many thanks

Base on ubuntu cloud image, listed as below
//  Please check with bionic image.
//  On arm64 xenial image was unable to initialize graphics for uefi hosts.
