Tips and Tricks
VirtualBox and Vmware use /dev/sda as naming convention. Qemu uses /dev/vda.

Grub can be used on BIOS and UEFI.
Refind and systemd can only be used on UEFI. (Set your virtual machine accordingly)
We manage our githubs with two scripts. Use them as a template but change them. Download here.
