Quo vadis?
After a huge marketing campaign, what has been announced today by Paul?
Version 4, tagged cloud OS. Truth is 'internal cloud' it's simply a new name for "Farms" (Citrix calls it "resource pool"). Yet there is no connection to 'external clouds'. -- And those would have to wear a 'VDC-OS'-shirt as well to work with the local 'internal cloud'.
OK, on to performance: There's a claim like '30 percent increase'.
Well lets take a look at foot note #1: they are comparing quad-core intel and six-core intel. Guess who wins.
The next claim is already softer: 'an estimate increase of 30% for XenApp'. I suppose the same hardware comparison is used for this assessment.
Let's compare quad-core with quad core and compare Xeon E5405 vs. Xeon E5570 and use a hypervisor where you can actually publish benchmarks without a huge approval process: SQL DBhammer on XenServer 5: '53 percent increase'. Citrix didn't even bother to enable Nested Page Tables (NPT)

xen to the power of two
Oracle surprises with a $7.1bn offer for Sun. The first thought might not be virtualization, but a second should be virtualization. After Citrix XenServer (11%) Sun's Hypervisor (7%) is the second Xen-based Hypervisor in production [NetIQ, Aug 08]. OracleVM will increase the percentage a bit.
What's the result?
VMware (56%) faces strong xen competitors:
- Citrix XenServer, outperforming VI3.5 41% (Tolly) to 100% (IBM/Trost); Sales up 40% in Q4 according the Q4 earnings call
- Oracle/Sun, the most prominent company denying OracleDB support on virtualization platforms except the Xen-based OracleVM; ready to distribute a JeOS-like OracleDB turnkey solution.
- XenCloud, Xen based clouds in production at Amazon, Google et all
What'll happen to VirtualBox? Ready to be merged with hosted Xen? ;-)

TNG George: The next generation of XenServer
Carl Fischer posted the announcement for beta for the next release of XenServer:
Project George contains several highly-requested new features:
- Active Directory integration. Specify the AD domain to use for authentication by the pool and use your AD credentials to connect to the pool via XenCenter and ssh. You control which AD users/groups are allowed access.
- Workload balancing. Guest and host performance metrics are used to create star ratings for individual VM placement and balancing recommendations for resource pools to achieve optimal performance.
- LVHD. Fast cloning and snapshots are now supported on all SR types through integration of our software VHD stack and LVM-based Storage Repositories (SRs).
- StorageLink integration. CLI-only support for a new StorageLink Gateway SR that adds native standards-based support for HP MSA, HP EVA, EMC Clariion, and NetApp storage arrays over iSCSI and Fibre Channel with automated initiator/fabric/array management.
- Expanded guest OS support. RHEL 5.3, Debian Lenny, and SLES 11 Linux guests.
- Enhanced beta problem reporting system. We've deployed an enhanced problem reporting system for use with the George beta. The forums will still be used for discussion but issues with the product can now be reported via a Jira-based ticketing system that supports designating issues as public or private. No more having to FTP your Server Status Reports (aka bug-tools)!

The return of performance comparisons: 'XenServer vs. VMware'
