# We use Cirrus for Vagrant tests and native CentOS 7 and 8, because macOS
# instances of GHA are too slow and flaky, and Linux instances of GHA do not
# support KVM.

# NOTE Cirrus execution environments lack a terminal, needed for
# some integration tests. So we use `ssh -tt` command to fake a terminal.
