Well, thanks...

   I'll take a look on this...

   I'm thinking a "cloud" will be a bit overkilling for our applications :D We
had only a dozen hosts with aprox. 100 VMs (linux, windows) on it. But, today,
almos everything is a "cloud" :D

   I already read the manuals of Eucaliptus and OpenStack, will take a look on OpenNebula, too...

   I'm thinking that we will have a "cloud" when we can use VDI to virtualize our desktop labs :D
For now we are searching a way to automatize the management of our VMs, but without all of the lights,
rings, and bells most of the cloud softwares had :D Our installation is prety simple: all hosts share some
LUNs from the Storage (via iSCSI). We had cLVM on it. The VMs had their own LVM partition. And we had a
couple o C and bash programs that do the magic. But, to deploy a new VM is almos the same as deploy a physical
host. No snaphsot (cLVM didn't had it working), and no clone (it almost kills the SAN net). This is why we are
searching for something else! VMware and Citrix made some demonstrations for our boss, but both needs MS-AD.

    Then we are searching for other options :D

    We already had talks with RH, thanks Jim Wildman, and well we aren't in a touristic area either :D 
    Well... we are still searching :D
