Description

Global configs
network.throttling.rate 40000

vm.network.throttling.rate 40000

rate limits is not set.

But i test the vm to another nfs ,speed is so poor.
Using wget to test ,the speed is similar.

so i edit the global config,but it seems not any role.

when i set it to 100000000,the vm can not be created.
agent log is :
