Subject: [PATCH] mcp: salt-formulas: Add & enable armband formula
FIXME: Re-enable apparmor.
FIXME: Detect baremetal and re-enable acceleration.
- install qemu-efi;
- install vgabios;
- disable apparmor as security driver for libvirt (temporary);
- fix missing link for vgabios binary blob;
- nova: virt_type=qemu (temporary, until we support baremetal too);
- nova: pointer_model=ps2mouse since AArch64 has no USB tablet;
- nova: cpu_model=cortex-a57;
- nova: libvirt driver: Add ttyAMA0 by default on AArch64;
- nova: libvirt driver: Use VGA video type by default on AArch64;

+Subject: [PATCH] nova: Update vga, console defaults for armv7, aarch64
+
+Nova hardcodes default options for both video=cirrus and console.
+armv7 and aarch64 VMs require video=vga, and since most applications
+use PL011 serial driver for guests, adding console=ttyAMA0 is also
+a nice UX addition.
