“-cpu host” can sometimes, for unclear reasons, lead to this error from
QEMU 8.1.1:
qemu-system-x86_64: CPU model 'host' requires KVM or HVF
This commit fixes it.
Inspired by
<47b56e7c19>.
* gnu/tests/virtualization.scm (run-childhurd-test)[test]: Prefer
“-cpu max” over “-cpu host”.
Change-Id: I11a8a68bb0532fe1f3fd2c34b4a7a5fdb7bccb57
* gnu/tests/virtualization.scm (%childhurd-os): Remove ‘services’ and
add ‘users’ to the GNU/Hurd ‘operating-system’ declaration.
(run-childhurd-test)[run-command-over-ssh]: Log in as “test” instead of
“root”.
This allows for zero-configuration offloading to a childhurd.
* gnu/services/virtualization.scm (operating-system-with-offloading-account):
New procedure.
(<hurd-vm-configuration>)[offloading?]: New field.
(hurd-vm-disk-image): Define ‘transform’ and use it.
(hurd-vm-activation): Generate SSH key for user ‘offloading’ and add
authorize it via /etc/childhurd/etc/ssh/authorized_keys.d.
(hurd-vm-configuration-offloading-ssh-key)
(hurd-vm-guix-extension): New procedures.
(hurd-vm-service-type): Add GUIX-SERVICE-TYPE extension.
* gnu/tests/virtualization.scm (run-childhurd-test)[import-module?]: New
procedure.
[os]: Add (gnu build install) and its closure to #:import-modules.
[test]: Add “copy-on-write store” and “offloading” tests.
* doc/guix.texi (Virtualization Services): Document it.
With offloading to a childhurd is enabled, allowing password-less root
login in the childhurd to anyone amounts to providing write access to
the host’s store to anyone. Thus, disable password-based root logins in
the childhurd.
* gnu/services/virtualization.scm (%hurd-vm-operating-system): Change
‘permit-root-login’ to 'prohibit-password.
* gnu/tests/virtualization.scm (%childhurd-os): Provide a custom ‘os’
field for ‘hurd-vm-configuration’.
* doc/guix.texi (Virtualization Services): Remove mention of
password-less root login.
This was added in 18e76f8905. Presumably,
the problem was that using compressed QCOW2 images makes the childhurd
slower, so it’s eventually marked as failing to start. By enabling KVM
inside the Guix System VM, we allow the childhurd to run on KVM, which
compensates the slowdown due to the use of a compressed image.
* gnu/tests/virtualization.scm (hurd-vm-disk-image-raw): Remove.
(%childhurd-os): Use default config for ‘hurd-vm-service-type’.
(run-childhurd-test)[test]: Pass “-cpu host” to the run-vm script.
Fixes a regression introduced in
a09c7da8f8.
* gnu/tests/virtualization.scm (run-childhurd-test)[test]: Import (ice-9
textual-ports) and (ice-9 match) in the marionette when needed.
Enable the QEMU guest agent interface in marionette VMs, run the
qemu-guest-agent service in one and try talking to it.
* gnu/build/marionette.scm (make-marionette): Enable the guest agent device.
* gnu/tests/virtualization.scm (run-qemu-guest-agent-test): New procedure.
(%test-qemu-guest-agent): New variable.

* gnu/tests/virtualization.scm (run-childhurd-test)[run-uname-over-ssh]:
Rename to...
[run-command-over-ssh]: ... this. Add 'command' parameter and honor it.
["SSH up and running"]: Adjust accordingly.
Using the new compressed-qcow2 image breaks this test.
* gnu/tests/virtualization.scm (hurd-vm-disk-image-raw): New procedure.
(%childhurd-os): Use it.
