Server virtualization

[satimis]

Hi folks,


Server virtualization.


What will be the best planning, strategy, etc. on server virtualization? Google found me tons of article sufficient for me reading a month. Can any folk shed me some light on;

- whether the host should not run any server or application on it except VMware/Xen/Virtualbox/qemn etc. there ?

- if there is only one fixed IP/public IP can it satisfy all servers running on the virtural box? OR multiple fixed IP/public IP are needed?

- Which servers can't be co-exist

- Network arrangement.

- Can I run Vyatta on the same box

Pointer would be appreciated. TIA
