Restoring R3.2 Templates/Standalones To R4.0
|
|
===========================================================
|
|
|
|
Although restoring R3.2 AppVMs to R4.0 generally works with no problem, there are additional steps that need to be performed when doing the same with Templates and Standalone VMs.
|
|
If these steps are not done, the result is an inability to start programs from the Qubes menu for the restored VM.
|
|
|
|
1. After restoring your Template or StandaloneVM, go to Qube Settings -> Basic tab.
|
|
Confirm Networking is set to one valid for your R4.0 system.
|
|
Then, under the Advanced tab, confirm Virtualization Mode is `PVH`, and that Kernel is set to `default`.
|
|
2. From a dom0 prompt, enter `qvm-run <templatename> gnome-terminal` (or `xterm` if `gnome-terminal` is not installed).
|
|
3. Once the terminal window comes up, open another terminal window to a known good R4.0 template.
|
|
4. From the known good template's terminal, `qvm-copy /etc/yum.repos.d/qubes-r4.repo` to the restored template.
|
|
5. Do the same with `qvm-copy /etc/pki/rpm-gpg/RPM-GPG-KEY-qubes-4-*`.
|
|
6. On the restored template's terminal, `cd` into the `QubesIncoming` subfolder that contains the files you copied over from the known good R4.0 template, then in `su` mode:
|
|
|
|
~~~
|
|
cp qubes-r4.repo /etc/yum.repos.d/
|
|
rm /etc/yum.repos.d/qubes-r3.repo
|
|
rpm --import RPM-GPG-KEY-qubes-4-*
|
|
dnf update
|
|
### You will receive an error about qubes-core-agent transaction failed, so continue with:
|
|
dnf install qubes-core-agent qubes-kernel-vm-support
|
|
systemctl enable qubes-gui-agent
|
|
poweroff
|
|
~~~
|
|
|
|
You should then be able to use your restored Template's shortcuts as normal.
