Xen Domain0 Configuration; Prerequisites To Install Dell Ulnm On Xen Enabled On Rhel5/Debian 5.0 (Lenny); Dell Ulnm Installation; Hardware Architecture - Dell PowerEdge UPS 500T User Manual

3.1. XEN DOMAIN0 CONFIGURATION

Before installing Dell ULNM on RHEL/Debian Lenny where Xen Domain0 is enabled, the following
configurations have to 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 virtual machines to function properly, it is recommended that GPL
Para virtualized (PV) drivers should be installed on each windows virtual machine.
3.2. PREREQUISITES TO INSTALL DELL ULNM ON XEN ENABLED ON RHEL5/DEBIAN 5.0
(LENNY)
1. Xen hypervisor (on RHEL/Debian) having minimum 5 MB free space.
2. Dell ULNM installation packages on RHEL/Debian.
Notes:
1. To allow a graceful shutdown of guest virtual machines, you have to install GPL PV drivers
on each virtual machine.
2. UPSs through RS232 connectivity will not be supported on RHEL5 as serial ports are used by
Xen.
