This page allows you to create a new virtual system, running inside an OpenVZ
container. Because Cloudmin usually creates OpenVZ systems from images, you must
have downloaded at least one image using the New System
Images page before an instance can be created.
The fields on this form that need to be filled in to create a Xen instance
are :
- System hostname
- This must be the name of the new container to create, which should not
include a domain name. Suitable instance names are like centos1 or
xen-foocorp.The final hostname of the instance will have
the DNS domain name selected for the host system appended.
- System description
- A short human-readable description for this new virtual system, like
Webserver for Foo Corp.
- Initial system image
- From this menu you must select the OpenVZ operating system image to start the
new system with. Cloudmin provides two types of images - base operating systems,
and full stacks with Virtualmin. In most cases, you will want to select
the latter.
- Root login mode
- This field allows you to set the initial password for the new OpenVZ instance.
Typically you will select Using password and enter a password into
the adjacent text box, which can then be given to whoever will manage the
server. Alternately, if you have any SSH keys registered with Cloudmin you can
select Using SSH key and choose a key from the menu next to it. Once
the instance is created, it will be configured to allow passwordless logins
using that key.
- Allow creation of Virtualmin domains?
- This setting determines if the newly create system can have Virtualmin
domains added to it. Typically you will want to leave this set to
Yes.
- Update Virtualmin packages?
- When this is set to Yes (as it is by default) and you are creating
a system from an image that includes Virtualmin Pro, all packages used by
Virtualmin will be updated to the latest available versions after creation
is complete.
- OpenVZ hosting system
- From this menu you must select the physical system on which you want
the OpenVZ instance created.
- IP address for OpenVZ instance
- Every new OpenVZ system is given a private IP address, which can either be
allocated automatically from the range defined for the host system, or
entered manually by selecting the Address option.
If the Cloudmin master runs a DNS server (highly recommended), an entry will
be added to the DNS zone selected for the OpenVZ host system for the full
hostname and Xen instance IP address.
- Memory allocated to instance
- OpenVZ instances can have a fixed upper bound on the amount of memory they can
use, which is controlled by this option. 256 is the minimum for a web
webhosting system with Virtualmin, but 512 is recommended.
- Disk space allocated to instance
- This field can be used to set a limit on the disk space the new OpenVZ
container can consume from the host system's filesystem.
When the Create button is clicked, Cloudmin will start the OpenVZ setup process.
Status messages will be displayed as each step is done. The total time
depends on the size
of the image, speed of the host system and speed of the network between the
host and the Cloudmin master, but around five minutes seems to be the average.
