Quoting from the Novell official announcement:
With the latest update to the Xen* hypervisor (version 3.0.4++), organizations can reduce costs through server consolidation and improved system management. New paravirtualized network and block device drivers will allow Microsoft* Windows* Server 2000/2003/XP to run unmodified in Xen virtual environments on SUSE Linux Enterprise Server 10 operating on Intel* Virtualization.
Seamless live migration is possible for paravirtualized virtual machines across distinct physical hosts.
SUSE Linux Enterprise 10 SP1 has many new features designed to support the workgroup services in Open Enterprise Server 2, including updates to the DNS, DHCP and LDAP modules, as well as support for paravirtualized NetWare 6.5.
Novell plans to release this service pack for May 2007.
