Using Spice with LibVirt KVM

http://wiki.centos.org/HowTos/Spice-libvirt

Viewing remote KVM Guest with usb redirection (linux mint maya 64):

Option 1:

https://launchpad.net/~bderzhavets/+archive/lib-usbredir73

Option 2:

Compile spice:

wget http://downloads.us.xiph.org/releases/celt/celt-0.5.1.3.tar.gz
  
wget http://spice-space.org/download/libcacard/libcacard-0.1.2.tar.bz2 ./configure --prefix=/usr
  
http://spice-space.org/download/gtk/spice-gtk-0.16.tar.bz2 ./configure --enable-usbredir=yes --with-python=yes
  
http://spice-space.org/download/releases/spice-protocol-0.12.2.tar.gz

install virt-viewer 5.4-3.

deb http://ubuntu.mirror.cambrium.nl/ubuntu/ raring main universe

libacl1.2.2.51-8

libattr1-1:2.4.46-8ubuntu2

libspice-client-glib-2.0-8

libspice-client-gtk-3.0-4

wget https://launchpad.net/~dnjl/+archive/build/+build/4077605/+files/virt-viewer_0.5.4-3~raring0_amd64.deb

Viewing remote KVM Guest with usb redirection using Ubuntu 13.04(live CD):

enable universe sources

sudo apt-get update
sudo apt-get install libapparmor1_2.8 libgtk-vnc-2.0 libgvnc-1.0 libspice-client-glib-2.0 libspice-client-gtk-3.0 libusbredirhost1 libusbredirparser0 libvirt0

now ubuntu 13.04 does have virt-viewer-0.5.4-1 at universe, but this version could not connect to spice type graphics.

it seems that the binary remote-viewer is not linked libspice-client-glib-2.0. That is why I’ll be using this version virt-viewer_0.5.4-3~raring0_i386.deb from https://launchpad.net/~dnjl/+archive/virtualization.

wget https://launchpad.net/~dnjl/+archive/build/+build/4077606/+files/virt-viewer_0.5.4-3~raring0_i386.deb
sudo dpkg -i virt-viewer_0.5.4-3~raring0_i386.deb

Note:

• both option has USB redirection.

• as of 02/04/13 linux mint virt-viewer from standard repo does not have usb-redirection suppport.

• virt-manager from http://virt-manager.et.redhat.com/download/sources/virt-viewer/virt-viewer-0.5.4.tar.gz has problem with glibc that why I looked for an updated version
