Xen Virtualization on Linux and Solaris

The most recent patches to Fedora’s Qemu 0.14 went into qemu-0.14.0-6.fc14.src.rpm on 03/31/2011. Following bellow is brief description of F14 KVM and Spice Server set up via “Libvirt Preview” ( http://repos.fedorapeople.org/repos/jforbes/virt-preview/fedora-14/SRPMS/). Configured KVM Server allows to create Ubuntu 10.10, 11.04 Desktop KVM beta 1 (64 bit), which may run in spice session. Notice that Virt-Manager 0.8.7-2 does have SPICE support. It allows to switch particular VM from VNC Server to SPICE Server and run spice session via GUI or connect to VM via command line locally or remotely.
**********************************************************************************************************************************************
In this case Spice Display Screen will show address 127.0.0.1 and connections to VM via spicec will be available only locally.
To get spicec working remotely remove Display VNC and “Add hardware” Display Spice. It will show you address 0.0.0.0
In this case connections via spicec will be available remotely
***********************************************************************************************************************************************
Ubuntu 10.10 Desktop,11.04 Desktop KVM beta 1 require “apt-get update,apt-get upgrade” to run stable in SPICE session

Configure fedora-virt-preview.repo :-
[root@fedorakvm yum.repos.d]# cat fedora-virt-preview.repo

# Place this file in your /etc/yum.repos.d/ directory
[fedora-virt-preview]

name=Virtualization Preview Repository for Fedora 14 Users
baseurl=http://repos.fedorapeople.org/repos/jforbes/virt-preview/fedora-$releasever/$basearch/
enabled=1
skip_if_unavailable=1
gpgcheck=0

Then run :-
# yum update

Install spice :-
# yum install spice-protocol spice-server spice-client

spice-server-0.8.0-1.fc14.x86_64
spice-gtk-0.5-1.fc14.x86_64

Create via virt-manager Ubuntu 11.04 Desktop (betta 1) KVM and run :-

# apt-get update
# apt-get upgrade

Due to presence SPICE support in Virt-Manager 0.7.2 switch to SPICE DISPLAY and start SPICE session via Virt-Manager :-





Connection to VM via command line :-



Automatically generated XML profile :-

Graphics section now looks like :-

<graphics type='spice' port='5900' tlsPort='-1' autoport='yes' listen='0.0.0.0'/>

Old way with modifying XML definition and connecting via command would work as well.
Create script /usr/tmp/qemu-spice :
cat /usr/tmp/qemu-spice
#!/bin/bash

exec /usr/bin/qemu-kvm $* \
-vga qxl \
-spice port=5930,disable-ticketing

# chmod 755 /usr/tmp/qemu-spice

and add to root’s .bashrc
export PATH=/usr/tmp:$PATH

Create via virt-manager Ubuntu 11.04 Desktop (alpha 3) KVM and install QXL driver via Synaptic manager. Say name of VM created is NATTY. Then run :-
# virsh dumpxml NATTY > Natty.xml
Edit XML file as follows

1. Change emulator to /usr/tmp/qemu-spice
2. Remove VIDEO section
3. Remove UUID section
4. Change VM’s name

[root@fedorakvm ~]# cat Natty.xml

Run :-
# virsh define Natty.xml
and new NATSP entry in Virt-Manager will be created. Start NATSP and connect via
# spicec -h localhost -p 5930
to NATSP
