Hello.
Is there any limitation of bandwidth for a Virtual Machine per default ?
I have a host with a bonding of 3 x 1Gb and the VM is connected to that
bonding. On the Engine interface on the VM status I see "Network" and it
has a percentage and a tiny graph. What that percentage is related to ? 1Gb
? 3Gb ? 10Gb ?
Is there anything that has to be done in order the VM can achieve speeds
over 1Gbps ?
To the external network, you cannot easily achieve >1Gb, unless you open
multiple connections that will go over multiple physical NICs. It depends
on the bond hashing policy. layer3+4 might make it easier to achieve. This
is not very different than a connection from the host. (I think UDP should
be easier, but it's less interesting?)
VM to VM traffic should easily overcome 1Gbps.
