Hello,

I am new to virtualization and even newer to Linux.

The FAQ and documentation for Xen seem to presume a certain level of prior low-level Linux and/or Xen knowledge. (None of which I have...)

Currently, my virtualization experience is mostly limited to the VMware Workstation products which seem fairly straight forward from a user's stand point.

Clearly, Xen is a very different beast from even VMware ESX server...

Can someone help answer up a few questions for me?

-- In the VWware world, each domain has the full illusion a system to it's self. I get the idea that this is not the case in Xen, but how can this be while still enforcing the integrity of each domain?

-- In the VWware world, I/O (Disk, Network, HID, VGA, etc..) is handled by "virtual hardware devices" that can be assigned to each domain at will, and are in turn somehow securely mapped and shared to their real world counterparts. Is this the case in Xen?

-- In the VWware ESX server product, identical memory pages among similar domains can be transparently consolidated to free up more physical RAM for the domains to use. Is this also the case in Xen?


Thank you,
David
