Coming approximately one month after the VirtualBox 6.1.2 point release, which introduced Linux host support for the latest Linux 5.5 kernel series (support for Linux guest additions wasn;t available), VirtualBox 6.1.4 is here to add full support for Linux kernel 5.5, for both host and guest. Additionally, VirtualBox 6.1.4 improved shared folder support on Linux guests by fixing loopback mounting of images. Other changes include the ability to report EFI support through DMI table and always report non-ATA disks as ready, as well as reduced stack space usage for INT 10h handlers.
