How to ssh to a QEMU XFCE desktop vm-image?

I have ssh working to a server image ...

nemo:~ $ ssh g1@server02.local
Last login: Sun Feb 25 22:11:42 2018 from fe80::1ccf:c589:7e5f:a21f%eth0

... but not to a similar xFCE desktop VM image ...

nemo:~ $ ssh g1@desktop01.local -vvv
OpenSSH_7.6p1, LibreSSL 2.6.2
debug1: Reading configuration data /Users/glc/.ssh/config
debug1: /Users/glc/.ssh/config line 48: Applying options for *
debug1: Reading configuration data /etc/ssh/ssh_config

debug2: ssh_connect_direct: needpriv 0
debug1: Connecting to desktop01.local port 22.
ssh: connect to host desktop01.local port 22: Connection refused

The VMs are built like this ...

	time guix system vm-image -M 4 -c 4 \
	     --image-size=5GB $VMDIR/$NAME.scm

The server runs this way ...

	sudo qemu-system-x86_64 \
	    -name $NAME \
	    -net tap,ifname=$NAME,script=$PWD/qemu-ifup,downscript=$PWD/qemu-ifdn \
	    -net nic,model=virtio,macaddr=$MACADDR \
	    -enable-kvm \
	    -m 5120 \
	    -daemonize \
	    -display none \
	    $VMDIR/vm.img

I run the desktop this way ...

	sudo qemu-system-x86_64 \
	    -name $NAME \
	    -net tap,ifname=$NAME,script=$PWD/qemu-ifup,downscript=$PWD/qemu-ifdn \
	    -net nic,model=virtio,macaddr=$MACADDR \
	     -enable-kvm \
	     -m 5120 \
	     -k en-us \
	     -vga qxl \
	     -spice addr=127.0.0.1,port=3001,disable-ticketing \
	     -device virtio-serial \
	     -chardev spicevmc,id=vdagent,debug=0,name=vdagent \
	     -device virtserialport,chardev=vdagent,name=com.redhat.spice.0 \
	     -daemonize \
	     $VMDIR/vm.img

... and can log in using the SPICE remote-viewer.

How do I enable ssh in to the desktop VM?

TIA - George

Could it be that perhaps ssh daemon failed to start?  Several people
have observed that failure mode, but nobody has been able to reproduce
it consistently in a VM yet, which has made troubleshooting difficult:

https://lists.gnu.org/archive/html/help-guix/2018-02/msg00022.html

Check the logs in /var/log/shepherd.log.  If you're suffering from this
problem, Shepherd will say that it failed to start ssh-daemon.

Thanks, yes that's it. It looks reproducible. I'll report a bug. -
