[OmniOS-discuss] [smartos-discuss] kvm network performance survey

[John Barfield]

CentOS still uses the traditional 2.6 numbering convention and back ports 
modules and features that they feel should be back ported while 
Ubuntu/Debian is following the kernel.org release cycle. (For the most 
part). 

In other words…its hard to tell the differences. I spent the better part 
of a couple of days trying to determine the built in virtio driver version 
and was not successful. 

So Centos is something like 2.6.32 (I’ll have to verify the actual 3rd 
octet) and Ubuntu is 3.8.X…again I’m just talking now but I’ll get the 
versions and verify. 

I’ve been redirected to several other projects so just had to deal with 
running Ubuntu as a solution to the performance problem at the time 
because I had already spent 2 weeks debugging CentOS.
