+The default @command{run-vm.sh} script that is returned by an invokation of
address@hidden system vm} does not add a @command{-net user} flag by default.
+To get network access from within the vm add the @code{(dhcp-client-service)}
+to your system definition and start the vm using
address@hidden(guix system vm config.scm) -net user}. An important caveat of
using
address@hidden user} for networking is that @command{ping} will not work,
because
+it uses the ICMP protocol. You'll have to use a different command to check for
+network connectivity, I'll leave this as an exercise for the reader.
+
address@hidden Connecting through ssh
+
+To enable ssh inside a vm you need to add a ssh server like
@code{(dropbear-service)}
+or @code{(lsh-service)} to your vm. The @code{(lsh-service}) doesn't currently
+boot unsupervised. It requires you to type some characters to initialize the
+randomness generator. In addition you need to forward the ssh port, 22 by
+default, to the host. You can do this with
address@hidden(guix system vm config.scm) -net user,hostfwd=tcp::10022-:22}. To
connect
+to the vm you can run
address@hidden -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -p
10022}.
+The @command{-p} tells @command{ssh} the port you want to connect to.
address@hidden UserKnownHostsFile=/dev/null} prevents @command{ssh} from
complaining
+every time you modify your @command{config.scm} file and the
address@hidden StrictHostKeyChecking=no} prevents you from having to allow a
+connection to an unknown host every time you connect.
+
address@hidden Using virt-viewer with spice
+
+The default qemu graphical client isn't very nice. As an alternative you can
+use the @command{remote-viewer} from the @command{virt-viewer} package. To
+connect pass the @command{-spice port=5930,disable-ticketing} flag to
address@hidden See previous section for further information on how to do this.
+
+Spice also allows you to do some nice stuff like share your clipboard with your
+vm. To enable that you'll have to in addition pass the following flags to
address@hidden: @command{-device
virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pci.0,addr=0x5}
address@hidden spicevmc,name=vdagent,id=vdagent}
address@hidden
virtserialport,nr=1,bus=virtio-serial0.0,chardev=vdagent,name=com.redhat.spice.0}.
+You'll also need to add the @code{(spice-vdagent-service)}.
