Virtualbox Only 32 Bit Available
Launch VirtualBox, and create a new virtual machine you will find the option for you to pick the versions are expended and 64-bit operating systems should be listed. There you go, if you only see 32-bit OS available that means something is wrong, and you are not utilizing the hardware to efficiently running those virtual machines. VirtualBox has a very low transfer rate to and from USB2 devices. Despite being an open source product, some of its features are available only in a binary form under a commercial license (see 'VirtualBox Extension Pack' below).
Hello,Virtualbox Only 32 Bit Available Free
I installed a .deb package virtualbox-6.0 (amd64) from Virtualbox Linux_Downloads on Ubuntu Mate 18.04.1 Bionic 64-bit host (HP notebook) and noticed that for new Windows and Linux guests there are only 32-bit versions available. The same 32-bit guest versions only were available. Also after installing virtualbox-5.2 on the same host via Software Boutique.
I have also an Ubuntu Mate 16.04 LTS 64-bit host installed earlier on an Asus notebook and an Oracle virtualbox v. 5.2.18 (r124319 Qt5.6.1) installed there which allows 64-bit Windows and Linux guests to be created. A Windows 8.1 64-bit guest was successfully created and used there.Virtualbox No 64 Bit Option
What's the issue of only 32-bit guests available to create in amd64 vIrtualbox on Ubuntu 18.04.1 64-bit host? Is it possible to enable Virtualbox with the option for 64-bit Linux and Windows guests?(I basically need at least a one 64-bit Windows (8 preferentially) guest).
