My boss asked me to install and configure a streaming server for live videos.
My choice for the server is red5, an open source streaming server.
Do you think can I use a kvm virtual machine for this server or it's
better not to use virtualization?
My hardware is a HP Proliant DL580 G5 with 4 Intel Xeon Quad core
processors and 16G ram.
My operating system is debian lenny amd64.

For a heavily I/O-bound load such as media streaming, it's better not to
use virtualization. There are some newer technologies such as SR-IOV
which may mitigate these problems, but I don't particularly suggest
straying that close to the bleeding edge on a presumably
mission-critical system.
If you really want to be able to compartmentalize tasks running on this
hardware, look at BSD jails, OpenVZ or Virtuozzo for an alternate
non-virtualization approach which doesn't have as much overhead on
I/O-heavy loads.

Thank you for your answer.
And for a public mail server do you think virtualization is ok?
