Linux Virtual Servers

[Northrup, Wilson]

How's your time synchronization over say, a week, on the linux servers
running on ESX?  Are you running any RHEL 64bit?   Any drift?

I have used Xen, VMware Workstation, VMware Server, VMware
Infrastructure 3
(certified professional now), and VMware Fusion (my Mac)...you can
probably
tell what I prefer.

In production, we are a large enterprise and we use Virtual
Infrastructure
3. We manage, in our development environment alone, about 60+ servers.
Management of these servers through Virtual Center is a breeze. Very
intuitive and GUI friendly. Unlike Xen. Xen is capable, but lacks the
refinements found in VMware. Also, you want to look at supportability,
VMware has extensive documentation freely available and a support base
that
blows away the competition.

For 4-10 servers, I would consider using VMware Server for users; and
you
use VMware Workstation to create the VMs. VMware Server is free, VMware
Workstation is ($189) but gives you ability to create VMs, replicate and
deploy them as new instances, etc. VMware Server is free and runs on
both
Windows and Linux (although getting it to compile on Linux may be a
challenge). I personally use VMware Workstation for Linux (it compiled
for
me on Fedora Core 8) for all my testing and development.

HI All,

I have a virtual Server setup request where i have some 32GB RAM with
other
required compatible hardware,and i need to create some 4-10 virtual
servers
environment with each physical node,for different users for different
developement/testing purposes.

I am confused with Xen/ OpenVZ? what is your opinion, in terms of
maximum
cap/ ease of install/configure/ segregation/ connflict etc.



Any idea/ suggestion will be of great help.

Thank you 

Debajit
