= Syrlug Virtualization Demo:

== Packages Needed
xen, qemu-system-x86 (qemu/kvm), other hypervisor w/ kernel modules
libvirt (provides virsh command line utility)
virt-manager (gtk based utility)



== Files / Dirs of interest
/etc/libvirt - all libvirt vm, network, and other configuration
/var/lib/libvirt - all libvirt data files, disk images, etc



== The libvirt remote daemon
Check to see if libvirtd is running:
  ps aux | grep libvirtd

If not start it via services interface
  sudo service libvirtd start
  sudo service libvirtd-qpid start
  sudo chkconfig --levels 35 --add libvirtd

Only needed it you require remote virtualization management.



== To create a guest Linux vm using virsh
sudo virsh help [command] # can configure libvirt, selinux to permit user vm management
sudo virsh list 
sudo virsh net-list
ifconfig -a  # vnet0, virbr0
brctl show
iptables -nvL -t nat

sudo vim /etc/libvirt/qemu/syrlug.xml  # copy presentation libvirt xml config into it
uuidgen
Set path to any bootable CD ISO image

sudo qemu-img create -f qcow2 /var/lib/libvirt/images/demo.img 10G
sudo virsh define /etc/libvirt/qemu/syrlug.xml
sudo virsh start syrlug
vncviewer localhost
ps aux | grep syrlug
sudo virsh list

If installing an OS, go through install process, shutdown, then change boot dev to 'hd'

Can also use virt-install, virt-manager



== To create a guest Linux vm using virt-manager
Gnome Menu > System Tools > Virtual Machine Manager
Start syrlug vm we just defined, view statistics / hardware profile
Can connect to more hypervisors, create more networks, hard drive devices
Create new syrlug2, BSD image (nice thing is after first restart, it'll change the boot device automatically)
