what is your preference and why for xen vs vmware - especially to attract more corporate clients. performance / ease of use / cost / corporate image and preference??

now that xen has been acquired I understand that they are owned by a large company and they are changing the pricing.

VMware is great for internal use but not suitable to hosting companies. Thats why you see Xen offered in so many places and VMware in almost none.

I think people use vmware on windows environment, easier than xen

Xen is open source and can be managed with a variery of 3rd party management tools. It is comparatively cheaper while providing the same basic functions.

You cant really compare these two as you are comparing a EMC Owned product to an Open Source product.

HOWEVER, you can compare Vmware ESX to "XEN" Enterprise.

Load balancing, clustering, iscsi, fc storage, etc.
