Operating System

Ubuntu Maverick Meerkat 10.10 (64-bit)

Warning:

Experimental guest operating systems have received limited testing, may not be present

in future product releases and must not be enabled on production systems. Citrix may not

respond to support requests regarding experimental features.

3.3. Deprecated Guests

The following table lists the deprecated guest operating systems in XenServer 6.2.0.

Operating System

Debian Lenny 5.0 (32-bit)

SUSE Linux Enterprise Server 9 SP4 (32-bit)

Windows Server 2008 (base release) (32-bit)

Windows Server 2008 (base release) (64-bit)

Windows Server 2003 (base release), Windows Server 2003 SP1 (32-bit)

Windows Server 2003 (base release), Windows Server 2003 SP1 (64-bit)

Windows Vista (base release), Windows Vista SP1 (32-bit)

Note:

There will be no option to engage Citrix's product development resources, and technical

workarounds may be limited or not possible for customers on unsupported guest operating

systems. If the support incident requires escalation to development for further guidance,

requires a hotfix, or requires a security update, customers will be asked to upgrade to a

supported service pack.

3.4. XenServer Product Family Virtual Device Support

The current version of the XenServer product family has the following general limitations on virtual devices for

VMs. Note that specific guest operating systems may have lower limits for certain features. The individual guest

installation section notes the limitations.

Virtual device Linux VMs Windows VMs

Number of virtual CPUs 32*16

Number of virtual disks 7 (including virtual CD-ROM) 7 (including virtual CD-ROM)

Number of virtual CD-ROM drives 1 1

Number of virtual NICs 7†7

*A maximum of 16 vCPUs are supported by XenCenter.

†except for SLES 10 SP1 and RHEL 4.x, which support 3. RHEL 5.0/5.1/5.2 support 3, but can support 7 when the kernel is patched with the

XenServer Tools. The same applies for Oracle and CentOS 5.0/5.1/5.2.
