Dell UPS 1000T - Manual (Page 134)

ULNM with Xen Virtualized Architecture 134
Installation Prerequisites
This installation and configuration of Dell ULNM has been tested upon following Xen environment:
• Red Hat 5 x86_64
• Debian 5.0 (Lenny) x86_64
The prerequisites to install Dell ULNM with Xen enabled on RHEL 5/Debian 5.0 (Lenny) are as follows:
• Xen Hypervisor (on RHEL/Debian) must have 5 MB free space.
• Dell ULNM installation packages on RHEL/Debian.
• To allow a graceful shutdown of the guest VMs, you must install GPL PV drivers on each VM.
• UPSs connected through RS-232 are not supported on RHEL5.
RHEL 5 and Debian 5.0 (Xen Domain0) Configuration Prerequisites
Before installing Dell ULNM on RHEL/Debian (Lenny) where Xen Domain0 is enabled, the following
configurations must be made:
• Hardware support for virtualization must be enabled on the host. This is an option in the BIOS. It is
possible your BIOS might have virtualization support disabled. Consult your BIOS documentation for
more details.
• For automatic OS boot on startup, you must configure the physical machine to do the same. This
setting is present in BIOS. For further information, see specific technical hardware documentation.
• In order to allow Windows VMs to function properly, it is recommended that GPL Para virtualized
(PV) drivers should be installed on each Windows VM.
Dell ULNM Installation Prerequisites
The prerequisites for Dell ULNM installation are described in “Installation Prerequisites” on page 13.
Also see “Compatibility” on page 10.
Dell ULNM Network Configuration Prerequisites
All hardware elements must have an operational network configuration that allows them to
communicate freely with each other.
Ensure that the following TCP/UDP ports are enabled on XenSever/Xen Hypervisor firewall:
• Connections on tcp port 4679 and 4680 to enable a remote access for supervision and configuration
through the Web Browser. These ports are reserved at IANA (http://www.iana.org).
• Connections through TCP port 80. It must be opened as a destination port (for output) on the
machine hosting the Dell ULNM.
