What is Spice server in QEMU?
QEMU uses spice-server to provide remote access to virtual machines through the Spice protocol. Virtual Device Interface (VDI) defines a set of interfaces that provide a standard way to publish virtual devices (e.g. display device, keyboard, mouse) and enables different Spice components to interact with those devices.
What is the SPICE client?
The Spice client is a program which is used by the end user to access remote systems through Spice. The recommended client is remote-viewer (which is shipped with virt-viewer). GNOME Boxes can also be used as a Spice client. spicec is an obsolete legacy client, and spicy is only a test application.

Is KVM better than VirtualBox?
KVM, a type 1 hypervisor, is smaller and faster than VirtualBox, but VirtualBox is more scalable. KVM is better integrated with Linux, and while it will work with other guests, it works best with Linux. In short, if you want to install a binary Linux distribution as a guest, it's better to use KVM.

What is remote viewer?
This scenario may appear a bit strange for those among my readers who know that remote-viewer is a network client application: Remote-viewer is normally used on a remote client systems to connect to the Qemu process for a VM on a server host via TCP over a LAN . In our present scenario, however, we start remote-viewer on the server host itself and achieve network capabilities only by making use of SSH. But such a scenario sets comparison standards regarding data transfer rates. Any real client/server solution should provide advantages over such a simple approach. We come back to such comparisons in the forthcoming articles of this series.
What module must be loaded in OpenSuse?
The module "module-native-protocol-tcp " must be loaded. On a standard Opensuse Leap system this is the case; see the settings in the files " /etc/pulse/default.pa " and for a specific user in " ~/.config/pulse/default.pa ".

The result of this sound redirection looks, of course, the same on pavucontrol on our remote client system as before.
Can remote viewer be used on a KVM?
In the last article we saw that "remote-viewer" can be used locally on the KVM-host to directly access the Qemu-emulator of a specific VM via a Unix socket instead of a network port. Its a simple and fairly effective method - though not well documented. We confined the right to access the socket for a VM to a specific group of users.
Can you have multiple heads on a virtio?
You see that we can set multiple heads for a virtio video device, too. A big advantage is that we do not need any special memory settings as for the QXL device.
How to access Spice console?
Method A: We access the Spice console of a VM by using remote-viewer on a remote client-system and interact with the VM via an unencrypted TCP connection to a specific network port on the KVM/Qemu-server.
What is a real remote configuration?
"Real" refers to the fact that both remote-viewer and virt-viewer are parts of a client/server architecture for the Spice protocol: This time we are going to run remote-viewer on the remote system.

What port is used for test VM?
We define a specific TCP port ( 20001) to be used for our test-VM. (Another additional VM on the KVM host would require the definition of another port). The " defaultMode ", by which we control whether TLS security measures are required to start the VM, is set to "insecure"; i.e. we neglect TLS encryption for the time being. Note also that I use a "virtio" video device. We made good experiences with it during our last experiments. If the virtio device should not work on your systems replace it by some reasonable QXL configuration.
What port does UVMa open?
We open local and router based firewalls in our (segmented) LAN for the communication of the client-system with the virtualization server over port 20001. On the KVM-server "MySRV" a privileged user "uvma" starts our already familiar test-VM "debianx" (in my case with a Kali OS on it) via virt-manager. Just for control purposes user "uvma" opens the Spice console on the server with a local remote-viewer instance (with 2 screens), logs in into the VM and starts a VM desktop session:
Can Spice console be accessed by anyone?
Furthermore: No authentication is required; the person having accessed the Spice console can work freely on the VM with the rights of the user who was actively using the desktop on the VM before . And the data exchange between MyLAP and MySRV occurs unencrypted.
Can you use HW acceleration on a virtual machine?
The HW graphics "acceleration" can be set to "yes" for the "virtio" device. HW acceleration will, however, not be used as long as Spice has the setting "<gl enable=no>". [You may try change this - good luck then with Nvidia cards and their proprietary drivers (it won't work). I will not cover HW acceleration of the virtual graphics in this series.]

When do I need to connect to the console of my virtual machine?
Sometimes I need to connect directly to the console of my virtual machines, typically this is usually when working with development or experimental VMs where SSH/RDP/VNC isn’t working for whatever reason, or when I’m installing a new OS entirely.
Can virt viewer run locally?
However virt-viewer has the capability to run locally and connect to a remote server, either directly to the libvirt daemon, or via an SSH tunnel. To do the latter, the following command will work for KVM (qemu) based hypervisors:
