Sun XVM VirtualBox 2.1.4 (32-bit) 64 Bit
Jens Loco
I have downloaded and installed the newest virtualbox 4.3.20 for my Windows 7 (64-bit OS), but when I want to install 64-bit Linux, the New->Create Virtual Machine only displays 32-bit option, no 64-bit option. Could anyone give any clues about this issue? Thanks very much in advance!
If you want to emulate 64 bit apps on a 64 bit host, your cpu needs a feature for that. Which duDE says, is an intel-specific copy-paste. The same support exists on AMDs too, there its name is AMD-v - maybe he forgot to mention.
Had the same problem, only seeing 32-bit versions for the host OS's. Started working after updating asus p8z77-v pro bios to latest and enabling virtualization support. Before the bios update, virtubox showed only 32-bit OS's.
Using the guidance in the answer by @Leo Chapiro I was able to install Debian Buster 10 with Gnome on Windows 10 on a Lenovo ThinkPad. Here's the step-by step way I enabled the 64 bit option in VirtualBox:
I login to phpVirtualBox interface and try to install new vm images, but "Create Virtual Machine" only has 32-bits dropdown list.
My PC board has 64 bit capabilities with Intel CPU. I also open Virtualization inside BIOS. My PC runs Win7 Ultimate 64-bits OS w/32MB RAM.
I used VirtualBox Windows version to setup openmediavualt debian (64-bits) image and run that images. Inside this images I installed virtualbox extras and I wanted to install a new virtualbox image inside this openmediavault extras package (virtualbox), everything went smoothly but why dropdown list only show 32-bits options ? I should expect to see 64-bits and 32-bits list, am I right ??
Other than the fact you are using nested virtualization with Virtualbox (meaning you will double the performance penalty), your install of Virtualbox on Windows is not passing the proper CPU flags to the virtual machine that are required to virtualize a 64bit machine. I haven't used virtualbox on Windows in years to know if you can do this or not. Why are you not just creating additional VMs on the Windows install of Virtualbox?
Such as I logined into phpVirtualBox web management interface ( ), and tried to install a new virtual machine, after put windows_xp.iso and start VM, I saw a small window showed up this vm (on right-up corner) was running and asked me to start to format this disk. I cannot connect to this vm. I used vnc tried to connect to this running installation vm without luck.
