- XenVMs running unmodified Windows Server 2000 are now supported (on computers with hardware
virtualization support - Intel VT or AMD-V CPUs)
- XenVMs running unmodified Windows Server 2003 and Windows XP SP2 now support multiple
virtual CPUs. All Windows XenVMs now also support up to 8GB of memory per XenVM (4GB
with XenExpress and XenServer), and have improved network performance.
- XenVMs running Windows now use the ACPI APIC Hardware Abstraction Layer (HAL), and support
- The Windows paravirtual drivers are now signed with WHQL certification on Windows Server 2003
and Windows XP SP2.
- Support for using the XenServer Host's physical CD-ROM to install Red Hat Enterprise Linux 5 and
SUSE Linux Enterprise Server 10 SP1 on initially non-paravirtualized XenVMs (on computers with
hardware virtualization support - Intel VT or AMD-V CPUs)
- Basic support for iSCSI SANs (XenEnterprise only) and enhanced host system hardware device support.
- Support for specifying VLAN trunk ports in virtual bridges on the XenServer Host (XenEnterprise only) 1
- The installation package has been redesigned. Instead of a single product installation disk, there is
now a main disk containing the basic packages to install the XenServer Host and Administrator Console,
and an additional disk containing support for creating Linux XenVMs
