Spice windows guest

On Linux, journalctl -t spice-vdagentd -t spice-vdagent will display the agent log messages. Since spice-server 0. Once the recording session is done, the spice-server-replay tool can be used to replay the previously recorded SPICE session, for example:. Introduction Spice is an open remote computing solution, providing client access to remote displays and devices e. Spice Client The Spice client is a program which is used by the end user to access remote systems through Spice.

Spice Agent The Spice agent is an optional component for enhancing user experience and performing guest-oriented management tasks.

VDI Port Device The Spice protocol supports a communication channel between the client and the agent on the server side. Spice Protocol The Spice protocol defines the messages and rules for the communication between the various Spice components. Features Multiple Channels The server and client communicate via channels.

Main control and configuration Display graphics commands images and video streams Inputs keyboard and mouse inputs Cursor pointer device position and cursor shape Playback audio received from the server to be played by the client Record audio captured on the client side Smartcard passthrough of smartcard data from the client machine to the guest OS USB redirection of USB devices plugged into the client to the guest OS. Image Compression Spice offers several image compression algorithms, which can be chosen on server initiation and dynamically at run-time.

Video Compression Spice uses loss-less compression for images sent to the client. Mouse modes Spice supports two mouse modes: server and client.

Server mouse When a user clicks inside the Spice client window, the client mouse is captured and set invisible. Client mouse Not captured and is used as the effective pointing device. Other Features Multiple Monitors any number of monitors is supported Arbitrary Resolution when using the QXL driver, the resolution of the guest OS will be automatically adjusted to the size of the client window.

Smartcard Redirection data from smartcard that are inserted into the client machine can be passed through to the guest OS. Bidirectional Audio Spice supports audio playback and recording. Available only when video streaming is enabled. Migration switching channel connectivity for supporting server migration Pixmap and Palette caching image data is cached on the client to avoid sending the same data.

See section [glossary] to be sure that you know difference between the host, client and guest. You can ignore the difference between guest, client and host if they are all running on the same machine. Running qemu manually The first thing to do is to create a guest image. Basic configuration This section will assume that you already have a running QEMU virtual machine, and that you are running it either through virt-manager, libvirt or through direct QEMU use, and that you want to enable Spice support for this virtual machine.

After stopping and restarting the virtual machine, it should be accessible with a Spice client. To add Spice support to an existing virtual machine managed by libvirt, you need to edit it:. This will setup a Spice session listening on port exporting your virtual machine display. You can also add a QXL device by appending -vga qxl to the command line.

Connecting to the guest The following section will show you basic usage of the Spice client. Configuration Using virt-manager. Client When you start the client as usual, if ticketing was enabled on the host, remote-viewer will pop up a window asking for a password before starting the Spice session.

To prevent this, the ticket can be also set by using the QEMU console command spice. Agent Agent support allows better integration with the guest. Client The client needs to have support for USB redirection. CAC smartcard redirection Spice has a dedicated channel for smartcard redirection, using libcacard, which currently supports limited CAC emulation.

Client In order for the client certificates to be shared with the remote, you need a NSS database configured to access the smartcard. Most Spice clients disable smartcard support by default, and need --spice-smartcard or similar configuration. It is necessary to setup CA and issue a server certificate before enabling this.

Use of TLS requires that x certificates be issued. This directory must contain ca-cert. TODO proof-read the following section:. Client We need to change 2 things when starting the client:. Generating self-signed certificates The following script can be used to create the various certificates needed to use a TLS Spice connection. Client When you start the client as usual, if SASL was enabled on the host, remote-viewer will pop up a window asking for a password before starting the Spice session.

Folder sharing The Spice client can share a folder with the remote guest. Guest configuration Windows. GL acceleration virgl OpenGL acceleration is currently local only it has to go through a Unix socket and it needs guest support. Configuration Using libvirt.

Connecting to the guest Connecting to the guest when virgl is in use is slightly different than usual. Configuration To configure your host and the vGPU device, follow this blog post. Spice guest additions While you will be able to remotely access your virtual machine through Spice without making any change to the virtual machine configuration, you can get better integration if you tweak it specially for Spice.

Windows guest The recommended way of getting all the needed drivers installed is to use the all-in-one Spice guest tools installer which can be found on spice-space. The package spice-protocol will be downloaded automatically as a dependency of package kvm. Guest requirements Linux guest. These instructions may be outdated. SPICE Simple Protocol for Independent Computing Environments is an open remote computing solution built for virtual environments which allows users to view a computing "desktop" environment.

The integrating of Spice into Proxmox VE provides a solution for interaction with virtualized desktop devices, like keyboard, mouse, audio and video. Spice achieves a user experience similar to an interaction with a local machine. Using Spice on Proxmox VE is easy and secure. It is integrated in the cluster environment, the user- and authentication system - and of course, all traffic is fully encrypted. Spice is not enabled by default.

I got this running with a linux virt-manager and windows guest. Seemed to be working, though extremely laggy while browsing directories. However, when I try to copy or access large files, say only MB and larger, the windows guest errors out with a message to indicate the file size limit is exceeded.

Have you ran into this before? Thank you. When I need to copy very large files back and forth, I usually just mount the disk image and work directly on it. It was far too laggy to be useful. For some of my windows-based applications, in order to access files over the share, I had to keep a windows explorer window open and continually refresh the shared folders. This would allow the application to access the files from a hang state. Apparently, whatever file library the application used was not compatible with this share.

Orders of magnitude better performance once I got the samba tricks figured out. Not terribly interesting for us… except that it says the sharing is done over 9p and mentions a 9p client. In the meantime, though, WSL got me thinking — how would I transfer files from one linux host to another? First we need to make the Video card a qxl device. Click on Video, and in the Model pulldown, choose, qxl. And Apply. Next we need to change the display from VNC to Spice.

You'll be prompted to add the Spice agent channels, click Yes. Now start the VM. So you don't need to fuss with a manual spice client like you did above. You still need to be sure that the guest has spice-vdagent installed and running. In the guest:. Create account Log in.
