|
|
|
|
(Shut down TemplateVM by any normal means.)
|
|

|
|
|
|
(Done.)

|
|
|
Detailed: Upgrading the Standard Fedora 21 Template to Fedora 23
|
|
----------------------------------------------------------------
|
|
|
|
These instructions will show you how to upgrade the standard Fedora 21
|
|
TemplateVM to Fedora 23. The same general procedure may be used to upgrade any
|
|
template based on the standard Fedora 21 template.
|
|
|
|
1. Ensure the existing template is not running.
|
|
|
|
[user@dom0 ~]$ qvm-shutdown fedora-21
|
|
|
|
2. Clone the existing template and start a terminal in the new template.
|
|
|
|
[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-23 ~]$ sudo yum clean all
|
|
[user@fedora-23 ~]$ sudo yum --releasever=23 --enablerepo=qubes*current-testing distro-sync
|
|
|
|
3. Shutdown the new TemplateVM via dom0 command line or Qubes VM Manager;
|
|
|
|
[user@dom0 ~]$ qvm-shutdown fedora-23
|
|
|
|
If you encounter no errors, proceed to step 7.
|
|
|
|
4. If `yum` reports that you do not have enough free disk space to proceed with
|
|
the upgrade process, create an empty file in dom0 to use as a cache and
|
|
attach it to the template as a virtual disk.
|
|
|
|
[user@dom0 ~]$ truncate -s 5GB /var/tmp/template-upgrade-cache.img
|
|
[user@dom0 ~]$ qvm-block -A fedora-23 dom0:/var/tmp/template-upgrade-cache.img
|
|
|
|
Then reattempt the upgrade process, but this time using the virtual disk as
|
|
a cache.
|
|
|
|
[user@fedora-23 ~]$ sudo mkfs.ext4 /dev/xvdi
|
|
[user@fedora-23 ~]$ sudo mount /dev/xvdi /mnt/removable
|
|
[user@fedora-23 ~]$ sudo yum clean all
|
|
[user@fedora-23 ~]$ sudo yum --releasever=23 --enablerepo=qubes*current-testing --setopt=cachedir=/mnt/removable distro-sync
|
|
|
|
(Poweroff via Qubes VM Manager. May need to be killed.)
|
|
|
|
5. If `yum` complains that there is not enough free space in `/usr/lib/modules`,
|
|
do this before reattempting the upgrade:
|
|
|
|
[user@fedora-23 ~]$ sudo mkdir /mnt/removable/modules
|
|
[user@fedora-23 ~]$ sudo cp -rp /usr/lib/modules /mnt/removable/modules
|
|
[user@fedora-23 ~]$ sudo mount --bind /mnt/removable/modules /usr/lib/modules
|
|
|
|
6. `yum` may complain:
|
|
|
|
At least X MB more space needed on the / filesystem.
|
|
|
|
In this case, one option is to [resize the TemplateVM's disk
|
|
image](/doc/ResizeDiskImage/) before reattempting the upgrade process.
|
|
(See **Additional Information** below for other options.)
|
|
|
|
7. After the upgrade process is finished, remove the cache file, if you
|
|
created one.
|
|
|
|
[user@dom0 ~]$ rm /var/tmp/template-upgrade-cache.img
|
|
|
|
8. Trim the new template (see **Compacting the Upgraded Template** for details
|
|
and other options).
|
|
|
|
[user@dom0 ~]$ qvm-trim-template fedora-23
|
|
|
|
9. (Optional) Remove the old default template.
|
|
|
|
[user@dom0 ~]$ sudo yum remove qubes-template-fedora-21
|
|
|
|
|
|
Summary: Upgrading the Minimal Fedora 21 Template to Fedora 23
|
|
--------------------------------------------------------------
|
|
|
|
[user@dom0 ~]$ qvm-clone fedora-21-minimal fedora-23-minimal
|
|
[user@dom0 ~]$ qvm-run -a fedora-23-minimal xterm
|
|
[user@fedora-23-minimal ~]$ su -
|
|
[root@fedora-23-minimal ~]# yum clean all
|
|
[user@fedora-23-minimal ~]# yum --releasever=23 --enablerepo=qubes*current-testing distro-sync
|
|
|
|
(Shut down TemplateVM by any normal means.)
|
|
|
|
[user@dom0 ~]$ qvm-trim-template fedora-23-minimal
|
|
|
|
(If you encounter insufficient space issues, you may need to use the methods
|
|
described for the standard template above.)
|
|
|
|
|
|
Differences Between the Standard and Minimal Upgrade Procedures
|
|
---------------------------------------------------------------
|
|
|
|
The procedure for upgrading the minimal template (or any template based on the
|
|
minimal template) is the same as the procedure for the standard template above,
|
|
**with the following exceptions**:
|
|
|
|
1. `gnome-terminal` is not installed by default. Unless you've installed it
|
|
(or another terminal emulator), use `xterm`. (Of course, you can also use
|
|
`xterm` for the standard template, if you prefer.)
|
|
2. `sudo` is not installed by default. Unless you've installed it, use `su` as
|
|
demonstrated above. (Of course, you can also use `su` for the standard
|
|
template, if you prefer.)
|
|
|
|
|
|
Compacting the Upgraded Template
|
|
================================
|
|
|
|
Neither `fstrim` nor the `discard` mount option works on the TemplateVM's root
|
|
filesystem, so when a file is removed in the template, space is not freed in
|
|
dom0. This means that the template will use about twice as much space as is
|
|
really necessary after upgrading.
|
|
|
|
If you have at least `qubes-core-dom0-2.1.68` installed or are on Qubes R3.0,
|
|
you can use the `qvm-trim-template` tool:
|
|
|
|
[user@dom0 ~]$ qvm-trim-template fedora-23
|
|
|
|
If you do not have `qubes-core-dom0-2.1.68` or are on older Qubes version, you can
|
|
compact the `root.img` manually. To do this, you will need about 15GB (the
|
|
TemplateVM's max size + the actually used space there) free space in dom0.
|
|
|
|
1. Start the template and fill all the free space with zeros, for example
|
|
with:
|
|
|
|
[user@fedora-23 ~]$ dd if=/dev/zero of=/var/tmp/zero
|
|
|
|
2. Wait for the "No space left on device" error. Then:
|
|
|
|
[user@fedora-23 ~]$ rm -f /var/tmp/zero
|
|
|
|
3. Shut down the template and all VMs based on it. Then:
|
|
|
|
[user@dom0 ~]$ cd /var/lib/qubes/vm-templates/fedora-23
|
|
[user@dom0 ~]$ cp --sparse=always root.img root.img.new
|
|
[user@dom0 ~]$ mv root.img.new root.img
|
|
|
|
|
|
Additional Information
|
|
======================
|
|
|
|
As mentioned above, you may encounter the following `yum` error:
|
|
|
|
At least X MB more space needed on the / filesystem.
|
|
|
|
In this case, you have several options:
|
|
|
|
1. [Increase the TemplateVM's disk image size](/doc/resize-disk-image/).
|
|
This is the solution mentioned in the main instructions above.
|
|
2. Delete files in order to free up space. One way to do this is by
|
|
uninstalling packages. You may then reinstalling them again after you
|
|
finish the upgrade process, if desired). However, you may end up having to
|
|
increase the disk image size anyway (see previous option).
|
|
3. Increase the `root.img` size with `qvm-grow-root`. It should be easy to
|
|
extend the `qvm-grow-root` tool in order to support PV (and not only HVM)
|
|
VMs. This is already done in R3.1.
|
|
4. Do the upgrade in parts, e.g., by using package groups. (First upgrade
|
|
`@core` packages, then the rest.)
|
|
5. Do not perform an in-place upgrade. Instead, simply download and install a
|
|
new template package, then redo all desired template modifications.
|
|
|
|
With regard to the last option, here are some useful messages from the mailing
|
|
list which also apply to TemplateVM management and migration in general:

|
Upgrading to Fedora 22
|
|
======================
|
|
|
|
You may choose to upgrade to Fedora 22 instead of Fedora 23. In that case,
|
|
simply replace version "23" with "22" in all above commands.
|
|
|
|
Known issues with Fedora 23
|
|
===========================
|
|
|
|
* [Graphical update tools (using PackageKit) does not work](https://github.com/QubesOS/qubes-issues/issues/982).
|
|
* [Dnf (new Fedora package manager) needs a lot of time to process repository metadata](https://bugzilla.redhat.com/show_bug.cgi?id=1227014), you may want to use `yum-deprecated` for now
|
|
* ["Terminal" shortcuts do not work because the desktop file in the VM has been renamed](https://github.com/QubesOS/qubes-issues/issues/1428). See the issue report for how to update your configuration to match.
