<b>Notice:</b>
|
|
The system requirements on this page are <em>necessary, but not sufficient,</em> for Qubes compatibility at a minimal or recommended level.
|
|
In other words, just because a computer satisfies these requirements doesn't mean that Qubes will successfully install and run on it.
|
|
We strongly recommend consulting the <a href="/hcl/">Hardware Compatibility List</a> to verify that Qubes can install and run on your specific model in the ways you need it to.

## Minimum
|
|
|
|
- **CPU:** 64-bit Intel or AMD processor (also known as `x86_64`, `x64`, and `AMD64`)
|
|
- [Intel VT-x](https://en.wikipedia.org/wiki/X86_virtualization#Intel_virtualization_.28VT-x.29) with [EPT](https://en.wikipedia.org/wiki/Second_Level_Address_Translation#Extended_Page_Tables) or [AMD-V](https://en.wikipedia.org/wiki/X86_virtualization#AMD_virtualization_.28AMD-V.29) with [RVI](https://en.wikipedia.org/wiki/Second_Level_Address_Translation#Rapid_Virtualization_Indexing)
|
|
- [Intel VT-d](https://en.wikipedia.org/wiki/X86_virtualization#Intel-VT-d) or [AMD-Vi (also known as AMD IOMMU)](https://en.wikipedia.org/wiki/X86_virtualization#I.2FO_MMU_virtualization_.28AMD-Vi_and_Intel_VT-d.29)
|
|
- **Memory:** 6 GB RAM
|
|
- **Storage:** 32 GB free space
|
|
|
|
## Recommended
|
|
|
|
- **CPU:** 64-bit Intel or AMD processor (also known as `x86_64`, `x64`, and `AMD64`)
|
|
- [Intel VT-x](https://en.wikipedia.org/wiki/X86_virtualization#Intel_virtualization_.28VT-x.29) with [EPT](https://en.wikipedia.org/wiki/Second_Level_Address_Translation#Extended_Page_Tables) or [AMD-V](https://en.wikipedia.org/wiki/X86_virtualization#AMD_virtualization_.28AMD-V.29) with [RVI](https://en.wikipedia.org/wiki/Second_Level_Address_Translation#Rapid_Virtualization_Indexing)
|
|
- [Intel VT-d](https://en.wikipedia.org/wiki/X86_virtualization#Intel-VT-d) or [AMD-Vi (also known as AMD IOMMU)](https://en.wikipedia.org/wiki/X86_virtualization#I.2FO_MMU_virtualization_.28AMD-Vi_and_Intel_VT-d.29)
|
|
- **Memory:** 16 GB RAM
|
|
- **Storage:** 128 GB free space
|
|
- High-speed solid-state drive strongly recommended
|
|
- **Graphics:** Intel integrated graphics processor (IGP) strongly recommended
|
|
- Nvidia GPUs may require significant [troubleshooting](/doc/install-nvidia-driver/)
|
|
- AMD GPUs have not been formally tested, but Radeons (especially RX580 and earlier) generally work well
|
|
- **Peripherals:** A non-USB keyboard or multiple USB controllers
|
|
- **TPM:** Trusted Platform Module (TPM) with proper BIOS support (required for [Anti Evil Maid](/doc/anti-evil-maid/))
|
|
- **Other:** Satisfaction of all [hardware certification requirements for Qubes 4.x](/news/2016/07/21/new-hw-certification-for-q4/)
|
|
|
|
## Choosing Hardware
|
|
|
|
- Please see the [Hardware Compatibility List](/hcl/) for a compilation of hardware reports generated and submitted by users across various Qubes versions.
|
|
(For more information about the HCL itself, see [here](/doc/hcl/).)
|
|
- See the [Certified Hardware](/doc/certified-hardware/) page.
|
|
- See the [Hardware Testing](/doc/hardware-testing/) page.
|
|
|
|
## Important Notes
|
|
|
|
- **Installing Qubes in a virtual machine is not recommended, as it uses its own bare-metal hypervisor (Xen).**
|
|
- Qubes **can** be installed on systems which do not meet the recommended requirements.
|
|
Such systems will still offer significant security improvements over traditional operating systems, since things like GUI isolation and kernel protection do not require special hardware.
|
|
- Qubes **can** be installed on a USB flash drive or external disk, and testing has shown that this works very well. A fast USB 3.0 flash drive is recommended for this.
|
|
(As a reminder, its capacity must be at least 32 GiB.)
|
|
Simply plug the flash drive into the computer before booting into the Qubes installer from a separate installation medium, choose the flash drive as the target installation disk, and proceed with the installation normally.
|
|
After Qubes has been installed on the flash drive, it can then be plugged into other computers in order to boot into Qubes.
|
|
In addition to the convenience of having a portable copy of Qubes, this allows users to test for hardware compatibility on multiple machines (e.g., at a brick-and-mortar computer
|
|
store) before deciding on which computer to purchase.
|
|
(See [hcl-report](/doc/hcl/#generating-and-submitting-new-reports) for advice on hardware compatibility testing.)
|
|
Remember to change the devices assigned to your NetVM and USB VM if you move between different machines.
