2. Define VM with xml as created above

   Code Block
   virsh define devcloud-kvm.xml

3. Create hard disk that XML points to:

   Code Block
   qemu-img create -f qcow2 /var/lib/libvirt/images/devcloud-kvm.qcow2 60G

4. Wiki Markup
   {toggle-cloak:id=NetXML}

   Create the network xml(click to show):

   Wiki Markup
   {toggle-cloak:id=NetXML}

   Wiki Markup
   {cloak:id=NetXML}

   Code Block
   cat > devcloud-kvm-net.xml << EOL <network> <name>private1</name> <uuid>f49f9a26-6c7a-ece4-9d4d-d2e295e6fb80</uuid> <bridge name='virbr1' stp='off' delay='0' /> <mac address='52:54:00:8D:BA:A5'/> </network> EOL

   Wiki Markup
   {cloak}

5. Create/edit networks required:

   Code Block
   virsh net-destroy default virsh net-edit default (change ip address range for dhcp so that we have some to manually assign) virsh net-start default virsh net-define devcloud-kvm-net.xml virsh net-autostart private1 virsh net-start private1

6. Start the vm, attach to vnc

   Code Block
   virsh start kvm-cloudstack virsh vncdisplay kvm-cloudstack

   • launch your favorite vnc viewer and connect to the localhost port returned by the previous command
7. Attach CentOS installation iso

   Code Block
   virsh attach-disk kvm-cloudstack ~/Downloads/CentOS-6.3-x86_64-minimal.iso hdc --type cdrom

   Note
   Once you attach the disk the VM should reboot on its own. But you may need to reboot it manually.

8. Install minimal CentOS

   Code Block
   Use 1 partition of 30G for /, and leave another 30G partition blank for a volume group
