In case of VMware I see it setting to 200 Mbps for guest traffic but in case of
Xen it is setting to ~25 Mbps

Subject: qos_algorithm_params (MRW): kbps: 25600 for Guest VMs?
Hi,
Any reason why we by default limit network rate to 25600 kbps (~25Mbps) on
guest VMs? Which parameter controls this setting? This is going to even control
guest to guest traffic as well. Why do we do this by default? It makes sense to
rate limit public but, unsure about guest traffic.
I see the following global params but they are meant to set this value to 200
Mbps
| Network | DEFAULT | management-server | network.throttling.rate |
200 | Default data transfer rate in megabits per second allowed in network.
|
| Network | DEFAULT | management-server | vm.network.throttling.rate |
200 | Default data transfer rate in megabits per second allowed in User vm's
default network. |
