Hello,
I need some explanation on this output from cpuinfo:

The system is a server rack dell poweredge R210 with ubuntu 12.04.
Why the cpu moodel appear as QEMU??
In it should be a Xenon cpu!!??!?

Thank you

It's probably a virtual machine?

I'm not sure.
But if that is the case means that ubuntu get emulated??

Most likely it's a virtual machine where the CPU is getting emulated.

Ok I found why:

Intel Virtualization Technology for Directed I/O
.....
Intel VT-d Technology enables multiple operating systems and applications to run in independent partitions. A partition behaves like a virtual machine (VM) and provides isolation and protection across partitions. Each partition is allocated its own subset of host physical memory.



Ok, not cpuinfo give me the info that ubuntu Virtual Machine, right?
Is there a command to find out the right specs of the hardware??
How to find out if there are other operating system on the machine?
Unfortunately I don't have direct access to it

Thank you

For the most part a VM is considered a stand alone system. To get the host's information you'd have to have some remote access to it. A client system won't help you much if you are using qemu. Some more advanced vm's can allow more direct connection to the hosts hardware and will report it in the client.
