I run IO-intensive and large ldm.pq systems on real hardware. Honestly,
that's everything I've got right now, which comprises 8 systems. I
experimented on Xen about 2 years ago and had problems with significant
delays and queue exhaustion. I considered the experiment a failure and
went on.
Bigbird and Sasquatch are on real hardware with 12GB of physical RAM,
but the next upgrade will take each to 24 GB of RAM and 10Gbe interfaces
facing the outside world. My internal processing machines are more
modest, but the systems doing radar image creation are also pretty hefty
to keep up with the load.
I'm a fan of virtualizing where it makes sense, but not more than that.

I run our LDM / NOAAPORT ingest on a HP DL380 G6 along with 6 other
VM's running for about a year and have had no problems what so ever. I
have migrated to virtualizing a lot of servers that do not require a lot
of performance or disk I/O over the past year or so. It saves on power
bills and makes administrating the system much easier.

What are the specific concerns about running on a virtual machine?
We are currently testing that combination right now. While I am
not doing the actual sysadmin work, our staff has indicated there is
plenty hardware to accomplish the task and lots of flexibility to
allocate the necessary VM resources.

I run my IDD and Noaaport LDM servers within Vsphere in a
production environment. It works great.

It was for experiment in a proof of concept. Wasn't really a
big deal
just something I noticed. I believe it was related to the
hardware clock
but I'm a user not an admin so I don't really remember the
resolution
since it was about a year ago now and was only testing. But
the vm
environment is nice for a quick setup, grab an ip off the
switch and
instant data...
