7. Architecture
More then 1 Host
●1 LVM for VM image storage
●Using iSCSI between Host and LVM
●Using its own internal network for the connection
between Host and LVM
●
8. Architecture
At least bond 2 network interfaces (bonding) for
the connection to LVM
●For the Host, it has 2 bridged network, 1 for WAN
and 1 for LAN in PowerBase
●
9. Management
use “virsh” and the tools started with “virt-” in
console to manage the VMs
●We can also use a GUI tool called Virtual Machine
Manager (virt-manager) on our GNU/Linux
Desktop to manage the VMs
●
10. Fast Cloning
For the Fast Cloning of VM images, we use LVM
snapshot to do the fast cloning
●We have built up some standard image for the
cloning of new VMs
●
12. P2V
dd the image into the VM’s LVM device if we have
the disk image
●
13. V2V
For Xen image, if it uses the original kernel (Full
virtualization), it can use directly on KVM;
otherwise it has to install the original kernel before
the boot in KVM
●For Virtual Box, VMware, there is a tool called
qemu-img to convert those images to RAW data
which could use in KVM.
●
15. New VM Creation
For Standard system, we have default VM to
clone
●For those do not have default image, we can use
virt-install to do the new VM installation
●
16. Live Migration
Live migration means that we can move VMs for 1
Host to another same configuration Host without
shutdown the VMs.
