1 *** BEFORE THE TALK ***
6 *** 1000 guests installed on my laptop for testing ***
8 virsh list .. showing guests
10 virsh dumpxml ... showing individual guests
14 *** 2000 create an overlay disk ***
16 Because I don't want to change my test guests ...
21 qemu-img create -f qcow2 -b /dev/fedora/f18x64 /tmp/f18.qcow2
22 qemu-img info /tmp/f18.qcow2
23 virt-install --import --disk path=/tmp/f18.qcow2,bus=virtio,format=qcow2 -n temp -r 2048
24 virt-viewer --connect qemu:///session temp
28 Run 'shutdown' inside the guest.
30 qemu-img info /tmp/f18.qcow2

59 --- If there are no immediate questions, then:
61 * How many people are using virtualization at all?
63 * How many people have virtualized some of their servers?
65 * How many people are using Amazon EC2 or another public cloud?
67 * How many people are running a public VPS or public cloud?
69 * How many people are running a private cloud or cloud-like service
72 * How many people are running VMware?
74 * How many people are running Xen?
76 * How many people are running KVM?
78 * What would stop you from moving away from VMware?
80 * What would stop you from moving to libvirt?
82 * What would stop you from moving to Open Stack or oVirt?
