Dom0
The table below shows the OS used for dom0 in each Qubes OS release.
| Qubes OS Version | Dom0 OS |
|---|---|
| Release 1 | Fedora 13 |
| Release 2 | Fedora 18 |
| Release 3.0 | Fedora 20 |

Note on dom0 and EOL
Dom0 is isolated from domUs. DomUs can access only a few interfaces, such as Xen, device backends (in the dom0 kernel and in other VMs, such as the NetVM), and Qubes tools (gui-daemon, qrexec-daemon, etc.). These components are security-critical, and we provide updates for all of them (when necessary), regardless of the support status of the base distribution. For this reason, we consider it safe to continue using a given base distribution in dom0 even after it has reached EOL (end-of-life).
TemplateVMs
The table below shows the TemplateVM versions supported by each Qubes OS release. Currently, only Fedora and Debian TemplateVMs are officially supported.

| Release 3.1 | 21, 22*, 23 | 7 ("wheezy")*, 8 ("jessie"), 9 ("stretch")* |
