[kvm-unit-test PATCH 3/5] travis.yml: Test with KVM instead of TCG (on x86)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Travis nowadays supports KVM in their CI pipelines, so we can finally
run the kvm-unit-tests with KVM instead of TCG here. Unfortunately, there
are some quirks: First, the QEMU binary has to be running as root, otherwise
you get an "permission denied" error here - even if you fix up the access
permissions to /dev/kvm first. Second, not all x86 tests are working in
this environment, so we still have to manually select the test set here
(but the amount of tests is definitely higher now than what we were able
to run with TCG before).
