Set up Qemu&Spice&Libvirt 0.9.6 USB Redirection on Ubuntu 11.10 (Oneiric Ocelot)



Following bellow is attempt to reproduce Hans de Goede blog entry at http://planet.spice-space.org/ on Ubuntu 11.10 with intent to build Qemu-kvm 0.15.0 with usb redirection network support per http://planet.spice-space.org/ via git repository git://people.freedesktop.org/~jwrdegoede/qemu :-

$ git clone git://people.freedesktop.org/~jwrdegoede/qemu
$ cd qemu
$ git checkout -B qemu-kvm-0.15.0-usbredir origin/qemu-kvm-0.15.0-usbredir
$ git log|more

Spice-Gtk-0.7.61 has been built up on current snapshot of git://anongit.freedesktop.org/spice/spice-gtk to obtain Spice-Gtk with usb redirection support working stable with Spice 0.9.1. Build done on Ubuntu Oneiric.Packaged version version of Spice-Gtk-0.7.61 is built up on mentioned git repository via Debian's 0.7-3 schema. Libusb-1.0-2:1.0.9-3ubuntu9 is built up on git://people.freedesktop.org/~jwrdegoede/libusb (pre 1.0.9). Usbredir-0.3.1-1ubuntu5 is built up on official release usbredir-0.3.1.tar.gz.

Qemu-kvm debian/rules contains:-

./configure \
--target-list="x86_64-softmmu i386-softmmu x86_64-linux-user i386-linux-user" \
--prefix=/usr \
--interp-prefix=/etc/qemu-binfmt/%M \
--disable-blobs \
--disable-strip \
--enable-spice \
--enable-usb-redir \
$(conf_arch)

Spicy should be run by root, view http://planet.spice-space.org/. Make sure you’ve done on server

$ sudo apt-get install ipxe

Per Hans de Goede :-
Select the options menu entry and make sure that the “auto redirect newly plugged in USB devices” option is checked. After this make sure the vm has keyboard focus (so close the options menu), plug in a new USB device and watch it show up in your vm

$ sudo apt-get install virtinst virt-manager virt-viewer

You might have to disable apparmor profile for libvirtd

$ sudo ln -s /etc/apparmor.d/usr.sbin.libvirtd /etc/apparmor.d/disable/
$ sudo apparmor_parser -R /etc/apparmor.d/usr.sbin.libvirtd
$ sudo adduser $USER kvm

Upgrade libvirt up to 0.9.6

sudo apt-get install libvirt-bin libvirt-dev libvirt-doc \
libvirt0 libvirt0-dbg python-libvirt libxen-dev

To start default network :-

sudo virsh net-start default
sudo virsh net-autostart default

After libvirt upgrade virsh will support of Qemu&Spice USB Redirection.It allows follow http://planet.spice-space.org/ update VM’s XML profile under /etc/libvirt/qemu/ as suggested in second blog entry of Hans de Goede :-

Change the first line from: <domain type=’kvm’> to:

<domain type=’kvm’ xmlns:qemu=’http://libvirt.org/schemas/domain/qemu/1.0′>

And add the following lines at the end, above the “</domain>” line: <qemu:commandline>

<qemu:arg value=’-readconfig’/>
<qemu:arg value=’/etc/qemu/ich9-ehci-uhci.cfg’/>
<qemu:arg value=’-chardev’/>
<qemu:arg value=’spicevmc,name=usbredir,id=usbredirchardev1′/>
<qemu:arg value=’-device’/>
<qemu:arg value=’usb-redir,chardev=usbredirchardev1,id=usbredirdev1,bus=ehci.0,debug=3′/>
<qemu:arg value=’-chardev’/>
<qemu:arg value=’spicevmc,name=usbredir,id=usbredirchardev2′/>
<qemu:arg value=’-device’/>
<qemu:arg value=’usb-redir,chardev=usbredirchardev2,id=usbredirdev2,bus=ehci.0,debug=3′/>
<qemu:arg value=’-chardev’/>
<qemu:arg value=’spicevmc,name=usbredir,id=usbredirchardev3′/>
<qemu:arg value=’-device’/>
<qemu:arg value=’usb-redir,chardev=usbredirchardev3,id=usbredirdev3,bus=ehci.0,debug=3′/>
</qemu:commandline>

Then run :-

# /etc/init.d/libvirt-bin restart

Manage VMs via virsh or Virt Manager having USB redirection support active in Spicy’s sessions.
