| |
| − | This section describes the procedure for installing VNX over Ubuntu 10.04 or 9.10. Open a root shell window and follow these steps:
| |
| − | <ul>
| |
| − |
| |
| − | <li>Install all packages required (basic development, virtualization, perl libraries and auxiliar packages):</li>
| |
| − | apt-get update
| |
| − | apt-get install build-essential qemu-kvm libvirt-bin vlan xterm \
| |
| − | bridge-utils screen virt-manager virt-viewer libxml-checker-perl \
| |
| − | libxml-parser-perl libnetaddr-ip-perl libnet-pcap-perl \
| |
| − | libnet-ipv6addr-perl liberror-perl libexception-class-perl \
| |
| − | uml-utilities libxml-libxml-perl libxml2-dev libgnutls-dev \
| |
| − | libdevmapper-dev libterm-readline-perl-perl libnet-telnet-perl \
| |

| |
| − | <li>If you use 64 bits version of Ubuntu, install 32 bits compatibility libraries:</li>
| |
| − | apt-get install ia32-libs
| |
| − |
| |
| − | <li>Install libvirt 0.9.3:</li>
| |
| − | /etc/init.d/libvirt-bin stop
| |
| − | wget http://libvirt.org/sources/libvirt-0.9.3.tar.gz
| |
| − | tar xfvz libvirt-0.9.3.tar.gz
| |
| − | cd libvirt-0.9.3
| |
| − | ./configure --without-xen --prefix=/usr && make && make install
| |
| − | /etc/init.d/libvirt-bin start
| |
| − |
| |
| − | '''NOTE''': VNX should work with libvirt versions from 0.7.5 to 0.8.5 (it has been mainly tested with 0.7.5 and 0.8.5). Note that, although libvirt 0.7.5 is available as a package in Ubuntu 10.04, it has some problems related with the Apparmor profiles configured for libvirt. If you disable Apparmor (with "/etc/init.d/apparmor stop"), VNX will work with libvirt 0.7.5 installed as package, however we recommend to download and compile version 0.8.5 as described above, in order to maintain Apparmor in your system.
| |
| − |
| |
| − | <li>Install Sys::Virt perl module:</li>
| |
| − | <ul>
| |
| − | <li>For Ubuntu 10.04, just install the libsys-virt-perl package</li>
| |
| − | apt-get install libsys-virt-perl
| |
| − | <!--
| |
| − | '''IMPORTANT NOTE''': Windows XP virtual machines started with VNX over Ubuntu 9.10 frequently hang when executing commands or with high traffic loads. The problem could be related with virtual network drivers. We are investigating the problem to find a solution. By now, Ubuntu 10.04 is the recomended platform to test VNX.

Install libvirt 0.8.8:
/etc/init.d/libvirtd stop
wget http://libvirt.org/sources/libvirt-0.8.8.tar.gz
tar xfvz libvirt-0.8.8.tar.gz
cd libvirt-0.8.8
./configure --without-xen --prefix=/usr && make && make install
rm -f /usr/lib/libvirt.so.0
ln -s /usr/lib/libvirt.so.0.8.8 /usr/lib/libvirt.so.0
rm -f /usr/lib/libvirt-qemu.so.0
ln -s /usr/lib/libvirt-qemu.so.0.8.8 /usr/lib/libvirt-qemu.so.0
rm -f /usr/lib64/libvirt*
ln -s /usr/lib/libvirt* /usr/lib64/
/etc/init.d/libvirtd start
Add symbolic link for kvm:
ln -s /usr/bin/qemu /usr/bin/kvm
Install VNX:
mkdir /tmp/vnx-update
cd /tmp/vnx-update
wget -N http://idefix.dit.upm.es/download/vnx/vnx-latest.tgz
tar xfvz vnx-latest.tgz
cd vnx-*
./install_vnx
Create the VNX config file (/etc/vnx.conf). You just can move the sample config file:
mv /etc/vnx.conf.sample /etc/vnx.conf
Disable SELINUX. If not disabled, virtual machines fail to start with:
Connecting to qemu:///system hypervisor...OK
libvirt error code: 1, message: internal error Process exited while reading console log output: char device redirected to /dev/pts/4
bind(unix:/root/.vnx/scenarios/simple_ubuntu/vms/ubuntu/ubuntu_socket): Permission denied
chardev: opening backend "socket" failed
Check that the hostname is correctly configured (in /etc/hosts it has to appear in the 127.0.0.1 and ::1 lines). If not configured you could get the following error when accesing virtual machine consoles:
virsh console ubuntu
error:Falló al obtener nombre del host local
Disable host firewall or, alternatively, allow the services you want to use among virtual machines.
Download root file systems from http://idefix.dit.upm.es/download/vnx/filesystems and copy them to /usr/share/vnx/filesystems directory:

Additional install steps for Dynamips support
- Install Dynamips and Dynagen:
yum -y install libpcap
wget http://downloads.sourceforge.net/project/dyna-gen/dynamips%20Linux%20RPM/0.2.8-RC2/dynamips-0.2.8RC2-1.i386.rpm
rpm --nodeps -i dynamips-0.2.8RC2-1.i386.rpm
wget http://downloads.sourceforge.net/project/dyna-gen/dynagen%20source%20_%20Linux/dynagen%200.11.0/dynagen-0.11.0-1.fc9.noarch.rpm
rpm -i dynagen-0.11.0-1.fc9.noarch.rpm
- Add dynamips to system start-up and start it manually for this time:
chkconfig --add dynamips
/etc/init.d/dynamips start
- Download and install cisco IOS image:
cd /usr/share/vnx/filesystems
# Cisco image
wget ... c3640-js-mz.124-19.image
ln -s c3640-js-mz.124-19.image c3640
dynagen /usr/share/vnx/examples/R.net
console R # type 'no' to exit the config wizard and wait
# for the router to completely start
idle-pc get R
Once you know the idle-pc value for your system, include it in /etc/vnx.conf file.
Additional install steps for Olive support
One additional step is needed to support Olive (Juniper) routers in VNX scenarios:
- Download old qemu bios from 0.10.6 version and copy it to /usr/share/qemu directory:
wget http://downloads.sourceforge.net/project/kvm/qemu-kvm/0.10.6/qemu-kvm-0.10.6.tar.gz
tar xfvz qemu-kvm-0.10.6.tar.gz
cp qemu-kvm-0.10.6/pc-bios/bios.bin /usr/share/qemu/bios-0.10.6.bin
