Supported Guest Operating Systems
• Windows® 2000 (any server version)
• Windows NT® 4.0 — Service Pack 4 or higher
• Red Hat™ Linux® 6.2, 7.0, 7.1 or 7.2
• SuSE™ Linux 7.3
•FreeBSD 4.5
Note: The standard Linux kernels in Red Hat Linux 6.2 have a bug reported at
www.redhat.com/support/errata/RHBA-2000013-01.html that can cause data
corruption under heavy memory load. Therefore, the standard Red Hat 6.2 installation
should not be used as a guest operating system to run server applications unless it is
patched. One way to correct the problem is to recompile the guest Linux kernel with
the configuration option CONFIG_X86_FX=n.
Virtual Machine Specifications
Each ESX Server computer can host up to 64 virtual machines with the following
capabilities and specifications.
Processor
• Intel Pentium II or later, (dependent on system processor)
• One processor per virtual machine on symmetric multiprocessor systems
Memory
• Up to 3.6GB per virtual machine
SCSI Devices
• Up to 4 virtual SCSI adapters per virtual machine with up to 15 devices per
adapter
• 9TB per virtual disk
Ethernet Cards
• Up to 4 virtual Ethernet adapters per machine
Note: Each virtual machine has a total of 5 virtual PCI slots, therefore the total
number of virtual adapters, SCSI plus Ethernet, cannot be greater than 5.
Floppy Drives
Up to 2 1.44MB floppy drives (physical drives or floppy image files) per virtual machine
CD-ROM
Up to 2 drives (physical drives or ISO image files) per virtual machine
