- Description: A new virtualization stack is being introduced that gets updated every six months.

Ubuntu is one of the most stable Linux distros out there, provided you're running its LTS release. Now imagine giving that up for a [rolling release model](https://itsfoss.com/rolling-release/). Feels exciting, right? Stop fantasizing then, as today's not the day that happens.

Instead, Canonical's [latest announcement](https://ubuntu.com//blog/ubuntu-virtualization-hwe-stack-confidential-computing?ref=itsfoss.com) introduces a rolling release approach for the virtualization stack, which swaps the usual LTS cycle for a faster, six-month upgrade cycle.

[Confidential computing](https://en.wikipedia.org/wiki/Confidential%5Fcomputing?ref=itsfoss.com) is the driving force behind this move, as Canonical's [Ijlal Loutfi](https://ubuntu.com/blog/author/ijlal-loutfi?ref=itsfoss.com) emphasizes that the different pieces of the stack rarely arrive at the same time.

A processor might support a new feature before the kernel can expose it, before [QEMU](https://www.qemu.org/?ref=itsfoss.com) can handle it, before [libvirt](https://libvirt.org/?ref=itsfoss.com) gives users a way to turn it on, and before the firmware and attestation tools are ready to make it actually usable.

## How does this work?

**Checking the installed virtualization variant with ubuntu\_virt\_helper.*

The virtualization HWE stack has four parts. `qemu-hwe` handles the hypervisor and system emulation; `libvirt-hwe` covers virtualization management; `edk2-hwe` brings newer [OVMF](https://wiki.ubuntu.com/UEFI/OVMF?ref=itsfoss.com) firmware for UEFI booting; and `seabios-hwe` does the same for BIOS compatibility.

It's the same approach Ubuntu already runs for kernels, just extended across the rest of the [virtualization](https://www.ibm.com/think/topics/virtualization?ref=itsfoss.com) chain.

**Switching to this is entirely optional**, and during these first two years of Ubuntu 26.04 LTS, all four packages get refreshed every six months, but only after a dry run in [an interim release](https://itsfoss.com/news/ubuntu-26-10-features/) first.

And stating the obvious, existing installations of Ubuntu will stay on the base stack unless someone decides to switch over to the new stack. A tool called [ubuntu\_virt\_helper](https://packages.ubuntu.com/resolute/ubuntu-helper-virt-hwe?ref=itsfoss.com) (*different package name*) handles that switch, since QEMU, libvirt, and firmware all need to move together as one unit rather than being swapped out piece by piece.

## Why should you care?

This is basically [Canonical](https://canonical.com/?ref=itsfoss.com) admitting that confidential computing has outgrown the two-year cadence [Ubuntu LTS](https://itsfoss.com/long-term-support-lts/) was built around.

The virtualization HWE stack is aimed at anyone running confidential VMs on **AMD SEV-SNP** or **Intel TDX**, regulated workloads that need stronger isolation, AI inference that leans on confidential computing, or accelerators, and private or sovereign cloud platforms that can't just hop to Ubuntu's interim releases.

These workloads are moving faster than Ubuntu's own release schedule can absorb, and nobody running them is waiting two years for a point release to catch up with the ever-evolving silicon vendors.

Canonical is positioning this as **a way to get LTS stability and newer hardware support at the same time**, instead of users needing to pick one over the other.

## Get started

Don't assume this is locked behind [Ubuntu Pro](https://ubuntu.com/pro?ref=itsfoss.com). Every example in Canonical's instructional material runs on plain apt commands without requiring you to log in to some portal.

The most basic one is to install the helper tool:

```
sudo apt install ubuntu-helper-virt-hwe
```

The rest, you will have to figure out by going through [the documentation](https://ubuntu.com/server/docs/how-to/virtualisation/virt-hwe/?ref=itsfoss.com) and running the following command:

```
ubuntu_virt_helper --help
```
