Resize (or Server resize) is the ability to change the flavor of a server,
|
|
thus allowing it to upscale or downscale according to user needs.
|
|
For this feature to work properly, you might need to configure some
|
|
underlying virt layers.

KVM
|
|
~~~
|
|
|
|
Resize on KVM is implemented currently by transferring the images between
|
|
compute nodes over ssh. For KVM you need hostnames to resolve properly
|
|
and passwordless ssh access between your compute hosts. Direct access
|
|
from one compute host to another is needed to copy the VM file across.
|
|
|
|
Cloud end users can find out how to resize a server by reading the
|
|
`OpenStack End User Guide <http://docs.openstack.org/user-guide/
|
|
cli_change_the_size_of_your_server.html>`_.

|
XenServer
|
|
~~~~~~~~~
|
|
|
|
To get resize to work with XenServer (and XCP), you need
|
|
to establish a root trust between all hypervisor nodes and
|
|
provide an ``/image`` mount point to your hypervisors dom0.
