Release Notes

20 Release Notes
ESX has
performance
issues because of
interrupt request
(IRQ) sharing.
When the system
initializes, VMkernel
assigns IRQ numbers to
all PCI devices based on
the system's hardware
topology and the
number of available
IRQs. If the number of
available IRQs are
limited due to hardware
constraints, two or more
PCI devices may be
assigned the same IRQ
number. In isolated
cases, IRQ sharing may
significantly impact
ESX Server
performance.
To resolve this issue, see

ESX/ESXi
4.0.x
The Windows
Server 2008
operating system
cannot be
automatically
pre-activated
on VMs.
When you install the
Microsoft Windows
Server 2008 operating
system on VMs using
the Dell Original
Equipment
Manufacturer (OEM)
installation media, the
operating system stops
working. This issue
occurs because the VMs
running on the Dell
system do not
automatically
pre-activate the
Windows Server 2008
operating system.
You must use a virtual key
to activate the Windows
Server 2008 operating
system. For more
information, see the white
paper, Dell OEM Windows
Server 2008 Installation on
Virtual Machines Using Dell
OEM Media at dell.com.
