SPICE (the Simple Protocol for Independent Computing Environments) is a remote-display protocol built for virtual environments.
Contents
Filesystem sharing
Note: There is a bug in virt-manager that causes the Filesystem option to be unavailable even though it will work on your system.
- Edit your guest's XML file with virsh (replace <name-of-guest> with the name of your guest VM):
virsh -c qemu:///system edit <name-of-guest>
- Add something similar to the following to your XML file, just above
</devices>:
<filesystem type='mount' accessmode='passthrough'>
<source dir='/path/to/share'/>
<target dir='share'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>
</filesystem>
- Quit your text editor. You can run the edit command again or check in virt-manager to make sure that the filesystem device you just added shows up.
- Add this line to /etc/fstab on your guest:
share /mnt 9p trans=virtio,version=9p2000.L 0 0
- Put the following in /etc/modules-load.d/9p.conf on your guest:
fscache 9p 9pnet_virtio
- Reboot, or just mount your new filesystem with mount, and you should be set.
Troubleshooting
Graphical corruption or lag with QXL video driver
- Add the following to /etc/X11/xorg.conf.d/20-qxl.conf:
Section "Device"
Identifier "qxl"
Driver "qxl"
Option "ENABLE_SURFACES" "False"
EndSection
- Reboot or restart X
DPI set incorrectly
If you have issues with your DPI being set incorrectly, you can manually override it for Xft by adding the following to .Xresources in your home directory:
Xft.dpi: 96
You will need to run xrdb $HOME/.Xresources from your .xinitrc if you do not already.
