Every time I do a fresh install of Virtual box on a different system. I encounter the dreaded “VERR_NOT_SUPPORTED” error. I finally decided to really document this issue once and for all.

Issue one# Virtual only showed 32bit options for virtual OS’s. After a system reboot , the 64bit option showed up

Issue two# The error “VERR_NOT_SUPPORTED” showed up after attempting to mount a fedora ISO. After further investigation it was determine to be the ISO was corrupt. I usually never match the sha256 hash for downloaded ISO’s. I guess I need to start doing this in the future. Because clearly the hash did not match for this particular ISO. I downloaded the ISO again and this time I used the torrent download. The error was cleared with the new version of the ISO.

Error Message:

Failed to open the disk image file C:\Users\cybersnacker\Downloads\Fedora-Live-Workstation-x86_64-23_Alpha-2.iso.

Could not get the storage format of the medium ‘C:\Users\cybersnacker\Downloads\Fedora-Live-Workstation-x86_64-23_Alpha-2.iso’ (VERR_NOT_SUPPORTED).
