Dear all,
If you ever have the time....
Here is another point of view on some of the VMware Announced features. Some of these announced features for the nearby 'VMware' futur have been there in Xenserver 4.x from the beginning, I will enlist them underneath.
XenServer (not to be confused with XenApp) has Xentools, Xenserver, Xenmotion , XenCenter , HA , Ressource Pools even Site Recovery ! ; moreover Citrix (who acquired XenSource)
has the Citrix Provisioning Server 4.5 for 9 months now whereas Vmware has plans to include it only either in Q4/2008 or Q1/2009 for ESX 4.
Another important item is :
The Citrix & Microsoft partnership and the collaboration to interface to each others solutions. Open the PDF to see what interoperability will be provided between the
The Xenserver solution has a lower license cost , its express edition is also license free , it has the better performance due to its 2nd generation paravirtualisation , and the Xencenter does not require a separate expensive database (SQL/Oracle) server for larger setups.
Xen uses the Xenserver itself as your 'VirtualCenter' server in a multiple master setup. Actually there is a single master
and multiple slaves (like the good old NT4 did). At any time when the master fails, a slave can get the master role and resume all functions of Xencenter.
Untill one is 'promoted' all READ kind of operations resume, only adding (CHANGING) stuff would need an actual promotion for an new master.
Imagine your Virtualcenter server breaks down, with 2 CLI commands on Xen you have another server being the master, On Vmware on the other hand ......
Another item is that Xen does not have VMFS but stores its data on ext3 partitions, the typical linux Logical Volume Manager is used.
This also makes upgrade paths much easier compared to Vmware.
Another item is that ISO images can be stored on NFS or accessed using SMB , so your ISO images can be stored on a windows system ! There is also a commandline tool for windows systems, so could execute the CLI on a windows station instead of on the Linux service console. All same CLI commands are supported on the windows exe.

That is one of the best ways to explain it Steve. Have you got a copy write on that J. I wonder if you are better off saying that VMware has "the most commercially mature and established hypervisor platform". Xen has been around for a long time too, but has not had the commercial drive and development funding that VMware has had.
Cheers,
Jeremy.

VMWare ESX = the most mature and established hypervisor platform
Xen Server= newer hypervisor, based on a better technical foundation, catching up with VMware, not as "Enterprise" able
MS Hyper-V= new kid on the block, based on XEN technology, has muscle of MS behind it, it is free, MS is targeting the management of virtual machines as their new market opportunity and pulling out all stops to get there first and knock VMWare out

Subject: [THIN] Vmware vs Citrix....
All -
Let me preface this by saying, I run a relatively small shop with a single CPS 4.0 farm and single WI/CSG deployment.
Now, Management wants to get involved with server virtualization. They are heading towards the direction of VMware but i do know that Citrix is in the virtualization space as well, but i don't know to what capacity. I, personally, have always thought that VMware would be the route to take to get server's and client's virtualized -- does citrix have something to compete with vmware ESX/Workstation ?
in other words, what exactly is citrix doing with regards to virtualization ?
