Jiang Jun updated MESOS-4420:
-----------------------------
Description:
We followed the docs to build and run Mesos Slave with network-isolator.
When we run it inside of a VM, the error message comes:
{quote}
Failed to read /sys/class/net/eth0/speed: Invalid argument
{quote}
It seems that {{/sys/class/net/eth0/speed}} is not available in a VM using
virtio.
The reason:
http://serverfault.com/questions/738840/get-link-speed-of-an-virtio-net-network-adapter
I prefer to warn the user or use some other methods to get physical link speed,
rather than quit the program. Nor, the Mesos Slave with
{{--isolation="network/port_mapping"}} will not be able to run in a VM. In some
production cases, people really need to install Mesos Slave in VMs.
