100d71f8a1
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.
