Hi,

I'm trying to find out a tool which will allow me to check nic speed inside the instance.

Thanks for your help.

If you use the virtio driver, the interface doesn't have a speed parameter. A similar question was answered on Stackexchange.

This is not specific to OpenStack, but any virtual machine using virtio.

If "real" drivers are used, the speed can be retrieved with ethtool or /sys/block/net/eth0/speed.
