When using the on-demand Virtual Systems some
limitations and considerations apply:
Please make sure you have read and
accepted the following points before you apply for a service.
Warnings
Network
| - |
Please do not disable a virtual machines network adapter or change the
IP Address. This will prevent communication with the server. |
|
| - |
Always make sure a backup of the server is
performed before making any changes to the Firewall or IP Table
as this can cause communication with the server to be lost. If this
occurs, restore the server from the backup. |
|
| - |
Be careful when trying to create a Virtual Private Network(VPN)
between the virtual server and a remote destination as there is a chance
that Network IP address duplication could occur which will prevent
communication to the server.
To prevent the possibility of network IP
address duplication, please take care when defining the network IP address
range to be used within the Global Cloud environment.

SSL-VPN connection function console
| - |
If you are using a proxy to access the internet and the SSL-VPN fails
to connect to the console, please exclude the following URLs in your proxy
settings.
• https://80.70.165.22/*
• https://80.70.165.24/*
|
Restrictions
There are certain restrictions that apply to the
trial period. Please refer to the trial agreement for further information.
Notes
Virtual Machine related
| - |
The CPU resources assigned to the virtual machine differ from the CPU
specs that are displayed. |
|
CPU Specs relate to the actual CPU on the host system. Please use the
System Manager in MyProtal to check allocated CPU resources |
|
| - |
When using sar command on CentOS, the “%steal” value seems to show a
disproportionately large number. |
|
This is because the system is running in a virtual environment is
displayed as such. The allocated CPU resources can be confirmed on the
System Manager in MyProtal menu. |
|
| - |
When “force-stopping” a virtual machine using the System Manager, The
OS will not shut down normally. Because of this, a Windows virtual machine
may display the "shutdown event" tracking dialog screen at the next
reboot. |
|
| - |
When starting a virtual machine from System Manager, it will show the
state “running”, however the System still needs to boot up. |
|
Please wait a few moments for the OS to finish starting. |
|
| - |
On Windows2003, in the following cases shutting down the virtual
machine may not complete successfully (Microsoft published information).
|
|
• The screen saver starts.
• Username and password dialog
is open
• A program such as Shutdown-Shutdown.exe is implemented
as a scheduled task. |
Billing Charges
| - |
Billing data is captured based on the virtual machine images deployed,
even if the Middleware is used to remove an image after it has been
deployed. |
SSL-VPN Console connection
| - |
A console connection can only be established via SSL-VPN across the
internet. |
|
Because of this an SSL-VPN connection cannot be established from
within the Intranet (FENICS VPN connection / internal connection in the
Data Centre) |
|
| - |
The SSL-VPN Connection is only to access the network created within
the SOP service from your local machine, it is NOT to access the console
on the virtual machines. |
|
Because of this neither Single User Mode for Linux nor Windows
Start-up menu (such as Directory Services Restore Mode, Safe Mode) is
available. |
|
| - |
If the client PC network or the internet connection is heavily loaded,
SSL-VPN connection may be disconnected console. |
|
When disconnected, please re-connect to the SSL-VPN console
connection. |
Networking
| - |
Global IP Addresses that are released may be re-allocated to other
systems after certain period of time. |
|
Please remove the IP addresses from DNS records before releasing and
make sure not to reference the IP addresses directly.
