Hi Kyle,

We are at Arizona State University, using VMware's Virtual Infrastructure 3.5.  
We actually began with dedicated hardware, and now have VMs for fedora itself, 
gsearch, mysql, and apache.

RHEL5 was our initial choice of OS - however, VI3.5 leverages VMI 
paravirtualization in the linux kernel, and RHEL5.X doesn't take advantage of 
it (yet).  Therefore we are running mostly Ubuntu 8.04 Server, which supports 
VMI out of the box.  It is also an extremely lightweight distribution, which we 
like.

The other thing you must be very careful of is your I/O performance.  When you 
start sharing your disk subsystem with multiple VMs, contention can become an 
issue and finding the bottleneck may be more difficult.  This is also the case 
for CPU contention, and is why VMware recommends scaling out (more VMs with 1 
CPU and lower memory) rather than up (throwing more CPUs / memory at a single 
VM).

Thanks,
Jeremy

Subject: [Fedora-commons-users] Fedora Commons on VMWare?

Does anyone have a production installation running in one or more virtual 
machines rather than using dedicated hardware?   We'd like to use RHEL5 on 
VMWare but haven't tested it yet.   Any advice would be appreciated.
