Hi @xsgordon. Thanks for your PR. I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with I understand the commands that are listed here. Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository. |

Last touch was #514. I'd really rather get something backed by CI, like this, which is entering CI via openshift/release#2143. Based on that (it still hasn't landed), we'd also want libvirt-client, libvirt-daemon-kvm, and bind-utils. Thoughts?

When I ran through this on a clean RHEL install the above was enough that I got bind-utils for "free" (may have been part of the minimal config?) but yes libvirt-daemon-kvm is needed as well.

What about libvirt-client? We may not need it for the build, but we have a few virsh calls in these docs. Or does it get pulled in by another package as well?

It gets pulled in by the above, specifically libvirt-client is a dependency of libvirt. qemu-kvm is not a dependency of libvirt, because Libvirt is hypervisor agnostic and can be used with other hypervisors, even if it is most commonly used with QEMU/KVM.
On RHEL (and IIRC Fedora as well) installing Libvirt doesn't actually
automatically mean you pulled in a hypervisor to actually run VMs on. As
a result you can encounter this error because qemu-kvm or equivalent is
not present:
Could not find any guests for architecure type hvm/x86_64
To avoid this, explicitly install qemu-kvm (if qemu-kvm-rhev or
qemu-kvm-ev are available in the machine's yum/dnf configuration they
will automatically get pulled in instead). The other package needed is
libvirt-daemon-kvm.
