64 bit guest are not supported by this host

Connect and share knowledge within a single location that is structured and easy to search. If yes, which virtualization products support it? Works perfectly. The processor needs to be 64bit capable and support VTX for it to work though.

Connect and share knowledge within a single location that is structured and easy to search. However, bit operation is not possible. Sometimes it is also called Hyper-V. For some obscure reason it often is hidden in the "security" section of the Bios. Most computers ship with the setting disabled by default.

Discussions related to using VirtualBox on Windows hosts. So I took a look at the Manual and found this! You need a bit processor with hardware virtualization support see Section You must enable hardware virtualization for the particular VM for which you want bit support; software virtualization is not supported for bit VMs. If you want to use bit guest support on a bit host operating system, you must also select a bit operating system for the particular VM. Since supporting 64 bits on bit hosts incurs additional overhead, VirtualBox only enables this support upon explicit request. On bit hosts which typically come with hardware virtualization support , bit guest operating systems are always supported regardless of settings, so you can simply install a bit operating system in the guest. This is especially true for bit Windows VMs.

Performance should be similar to bit guests unless your bit setup requires more RAM to be allocated, of course. Learn more about Teams. However you are better off using the 64bit OS as host anyway.

Connect and share knowledge within a single location that is structured and easy to search. VirtualBox supports bit guest operating systems, even on bit host operating systems, provided that the following conditions are met:. Since supporting 64 bits on bit hosts incurs additional overhead, VirtualBox only enables this support upon explicit request. On bit hosts which typically come with hardware virtualization support , bit guest operating systems are always supported regardless of settings, so you can simply install a bit operating system in the guest. Note that VirtualBox also supports bit guest operating systems, under the following conditions:.

I would like to have an Ubuntu When I try booting the Ubuntu Your bit guest will fail to detect a bit CPU and will not be able to boot. In order to be able to run a Bit system in a VirtualBox, you need a cpu which supports virtualization.

In order to still be able to run a bit application as was said in a comment let me suggest you run Ubuntu bit either by a dual-boot, or as a live system from USB. A live system in persistence mode allows to save files in a reserved area. Support for bit guests requires CPU virtualization support in the host, A. VT-x or AMD-v.

I'd suggest using hardinfo to check your processor's features. AI-generated content is not permitted on Ask Ubuntu. Nomen Nomen 21 1 1 bronze badge.

Starting with Version 2. Nice, thank you, I do acknowledge that this was answerer before my selected answer, whom I chose as it was a bit more comprehensive.

VirtualBox supports bit guest operating systems, even on bit host operating systems, provided that the following conditions are met:. Goodbye Gunnar Hjalmarsson I suggest you keep the condescending links and opinion to yourself and stick to answering the questions until you have a little more rep and know how things work around here. Not sure if its still supported but VMWare certainly used to support this providing your processor had the hardware support for virtualisation. If yes, which virtualization products support it? It just would have been nice to take a look at that thread. And I did the same with 64 bit Server on 32 bit XP. My previous employer used to provide laptops with 32bit OS only, but that didn't stop me from running x64 Linux and Windows to run tests on virtual machines.
