Hello

I have a physical RHEL 7.7 host with libvir and KVM installed:

[root@clusterdev01 ~]# more /etc/redhat-release 
> Red Hat Enterprise Linux Server release 7.7 (Maipo)


[root@clusterdev01 ~]# virsh version --daemon

I'm following the instructions listed in 
https://coreos.com/os/docs/latest/booting-with-libvirt.html to install 
Container Linux on this physical host.

After creating the domain.xml configuration, as per the instructions, 
starting the VM fails:

[root@clusterdev01 ~]# virsh start container-linux1 
> error: Failed to start domain container-linux1
> error: internal error: process exited while connecting to monitor: 
> qemu-kvm: -fw_cfg: invalid option


>From a search, I see that the issue was discussed here: 
https://github.com/openshift/installer/issues/455 and here: 
https://bugzilla.redhat.com/show_bug.cgi?id=1674422 and both issues were 
closed.

I saw that a suggested workaround to this is to install the version of 
qemu-kvm included in RedHat Virtualization, namely qemu-kvm-rhev, but that 
doing so is not supported: https://access.redhat.com/solutions/629513

To me, this looks like running Container Linux on RHEL 7.7 with libvirt is 
broken, which isn't great as I wanted to install OpenShift on these hosts.

Any ideas on the best way to get around this issue?
