I have a dual xeon, dual core box running the xen x86_64 kernel. I've decided against running any guest OS'es most of the time, so I'd like to install an smp kernel, that would hopefully allow me to install and use the nvidia drivers for my quadro FX1500 graphics card.
I did a yum list kernel* but I don't see any smp kernels.
Do I need to do a full reinstall w/o virtualization, or does the plain kernel.x86_64 0:2.6.28-8.1.14.el5 support smp?
I spent an hour or so googling and didn't find any clear answer, but I may not have looked in the right place.
thanks, -chuck

In centos5, there is no longer a separate smp kernel. It's supported directly within the main distribution kernel now. If you're using an smp system, you'll see SMP listed in uname -a.
This was a change in the main kernel tree as well, though I don't recall the exact version this started. I think around 2.6.16 or so.

Well ... that "SMP" appears in uname -a even on a single-cpu system.

P.S. You are perhaps not perfest despite your declaration on the #channel this morning. :-)

I'm sure he was just making sure you were awake...

Oops :-P
I've only got multi-cpu systems these days and didn't test it out in a vm. Glad to see you're keeping me honest!

Could it be that they are only shipping the SMP kernel? I should still work on systems with one cpu.

Yes ... there is only an SMP kernel shipped. It works with 1 or more processors. It does not have SMP in the kernel name, it does show SMP in uname -a.

CentOS-5 kernels are all smp-enabled but they work on uni-processor systems just fine. If you, for some reeason, must use a UP-kernel, you'd have to rebuild it from the source.
