Hi All.

I have currently a small problem to solve. I have a kvm virtual machine which in output of

ifconfig eth0 | egrep 'RX packets|TX packets'

RX packets:792681304 errors:0 dropped:560728 overruns:0 frame:0

TX packets:716661674 errors:0 dropped:0 overruns:0 carrier:0

show dropped packets. I think that rx buffer is to small (no strange messagess in dmesg) and would like to make it larger. But when I try a solution from

http://www.scottalanmiller.com/linux/2011/06/20/working-with-nic-ring-buffers/

I get:

ethtool -g eth0

Ring parameters for eth0:

Cannot get device ring settings: Operation not supported

So what is the proper way to make rx buffers larger in this situation?

Best regards,

Rafal Radecki.
