Description of problem:

I'm sure I've seen this bug before, but I cannot find it now ...

$ guestfish --format=raw -a ssh://192.168.0.87/disk.img run
[...]
Original error from libvirt: internal error: 'ssh' protocol is not yet supported [code=1 int1=-1]

In this case 192.168.0.87 is an ssh server which is reachable
using ssh-agent (as is required by the ssh driver in qemu).

It appears this error comes from:

src/qemu/qemu_command.c:qemuBuildNetworkDriveStr

        case VIR_STORAGE_NET_PROTOCOL_SSH:
            virReportError(VIR_ERR_INTERNAL_ERROR, "%s",
                           _("'ssh' protocol is not yet supported"));
            goto cleanup;

Version-Release number of selected component (if applicable):

libvirt-daemon-3.1.0-1.fc27.x86_64

How reproducible:

100%

Steps to Reproduce:
