The file name of the qcow2 image. @end table +The default @command{run-vm.sh} script that is returned by an invokation of +@command{guix 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 +@command{`guix system vm config.scm` -net user}. An important caveat of using +@command{-net 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, like for example @command{curl}. + +@subsubsection 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 + +@example +`guix system vm config.scm` -net user,hostfwd=tcp::10022-:22 +@end example + +To connect to the VM you can run + +@example +ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -p 10022 +@end example + +The @command{-p} tells @command{ssh} the port you want to connect to. +@command{-o UserKnownHostsFile=/dev/null} prevents @command{ssh} from complaining +every time you modify your @command{config.scm} file and the +@command{-o StrictHostKeyChecking=no} prevents you from having to allow a +connection to an unknown host every time you connect. + +@subsubsection Using @command{virt-viewer} with Spice + +As an alternative to the default @command{qemu} graphical client 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 +@command{qemu}. 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 also have to pass the following flags to @command{qemu}: + +@example +-device virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pci.0,addr=0x5 +-chardev spicevmc,name=vdagent,id=vdagent +-device virtserialport,nr=1,bus=virtio-serial0.0,chardev=vdagent, +name=com.redhat.spice.0 +@end example + +You'll also need to add the @pxref{Miscellaneous Services, Spice service}. + @node Defining Services @subsection Defining Services |
