How to detect ethernet uplink speed on CentOS 6 OpenVZ VPS

Question

I recently purchased a VPS which was advertised as a 100Mbps uplink but the promotion promised a free upgrade to a 1Gbps uplink. I'm trying to find out if I received the upgrade with various methods without any luck.

Running lspci I get:

[root@host ~]# lspci
pcilib: Cannot open /proc/bus/pci
lspci: Cannot find any working access method.
[root@host ~]#

Similarly, running lshw and ethtool does not show any network information either.

ifconfig -a shows:

[root@host /]# ifconfig -a

          inet addr:127.0.0.1  Mask:255.0.0.0

Perhaps this server doesn't have PCI, if that is the case is there any other way to find out the uplink speed?

That explains your problem. (And every other problem you're going to have in future...) — Michael Hampton, Dec 24 '13 at 03:54
@MichaelHampton There's nothing wrong with OpenVZ, it's actually better then Virtuozzo from HostGator. They charged me $20.00 a month for 300mb of ram and 677mhz cpu and took a good minute to shutdown. OpenVZ reboots in under 2 seconds, can't beat that quality. — SSpoke, Dec 24 '13 at 03:57
Virtuozzo and OpenVZ are practically identical. The cost of one provider or another has nothing to do with it. — Michael Hampton, Dec 24 '13 at 03:59
@MichaelHampton Are you saying there is no way to check the network uplink speed with a OpenVZ virtualization? — SSpoke, Dec 24 '13 at 04:07
I have to agree with @MichaelHampton - OpenVZ is not helpful here. It is not a "true" virtualization platform (ie, Type 1) such as Xen, VMware et al. You don't actually have you own kernel instance with an OpenVZ - you're running a shared kernel will the host and all other containers. Without a complete kernel, you're lacking pretty much any ability to interrogate "hardware" (eg, to find ethernet link-speed) — fukawi2, Dec 24 '13 at 04:10

I found out a way to test whether you are on a 100mbps or 1gbps uplink, you download this python script for running a speed test with speedtest.net

wget -O speedtest-cli.py https://github.com/sivel/speedtest-cli/raw/master/speedtest_cli.py

Then once you have the script you do:

python speedtest-cli.py --share

Here is my result:

Which proves my workstation is on a full-dulpex transmission 1 gigabit per second uplink

Use ethtool with an argument for the interface e.g. ethtool eth0.

Dmesg may have other useful information but it is transient.

Sending `ethtool eth0` just breaks to a new line without any output. `ifconfig -a` shows: `lo`, `venet0`, `venet0:0` and doing `ethtool venet0`, etc. yields the same result. – SSpoke Dec 24 '13 at 03:34
