These instructions will show you how to upgrade the standard Fedora 21
TemplateVM to Fedora 22. The same general procedure may be used to upgrade any
TemplateVM to Fedora 23. The same general procedure may be used to upgrade any
template based on the standard Fedora 21 template.
1. Clone the existing template and start a terminal in the new template.
[user@dom0 ~]$ qvm-clone fedora-21 fedora-22
[user@dom0 ~]$ qvm-run -a fedora-22 gnome-terminal
[user@dom0 ~]$ qvm-clone fedora-21 fedora-23
[user@dom0 ~]$ qvm-run -a fedora-23 gnome-terminal
2. Attempt the upgrade process in the new template. For now you need to enable testing repository to do that.
[user@fedora-22 ~]$ sudo yum clean all
[user@fedora-22 ~]$ sudo yum --releasever=22 --enablerepo=qubes*current-testing distro-sync
