[GRLUG] VMWare ESXi Was: Raid, LVM, and Cheap Storage

[Ben DeMott]

My Former employer did the same thing, diddo on the VMWare Server
Experiences.

For those that have not gone down the virtualization road -
Beware Exchange 2000 servers, Exchange Mail Stores without SP2, Domain
Controllers, and Conversion!

VMware Converter had a bug prior to version 3.01 - in which it corrupted the
network stack/winsock.
Once the conversion was done the damage could not be reversed - so beware.
The problem shows up more on Linux hosts, your network adapter (only when
loaded) will appear to go from maximum throughput to ~10kb/s over and over
again several times a second.

All of our virtual machines were built from scratch - Mostly from paranoia.

Microsoft originally stated they would be supporting Linux as a guest
operating system (but they didn't), I'm not sure what their current
hypervisor offerings are - and what memory limitations are for their free
products. If they would have only supported Linux as a
guest, or allowed for more memory on the host I would have been open minded
- anyone using Microsoft Virtualization?
