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 3.1 Fedora 20
Release 3.2 Fedora 23
Release 3.2.1 Fedora 23
Release 4.0 Fedora 25

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.
