CentOS virt - Jul 2014 - I have a question regarding the virtual scsi adapter.

I have a very old system which has a self compiled kernel.
It' supports sata and megaraid but not LSI SCSI or BUSLOGIC scsi.
I am not sure what SCSI adapter is being used on CentOS KVM host and 
there for what kernel options to enable in the new compiled kernel.
I have tried to add LSI logic and it seems like still not recognizing 
the SCSI device.
I have another kernel that do work but it was build with lots of modules 
and I am not sure which one of them is the appropriate one.
The linux kernel version of the guest is 2.6.19.

If someone has a .config file that has all the needed modules complied 
in the kernel I will be happy to see it.

Thanks,
Eliezer
