vHost User Interface Startup Configuration

The dataplane has a few options which govern startup behavior of vHost User Interfaces:

dataplane vhost-user coalesce-frames <num>

Minimum number of packet frames before transmission. Default is 32 frames.

Tip

A lower value, such as 4, has greatly improved communication speed between two VMs on the same hypervisor during internal testing.

dataplane vhost-user coalesce-time <us>

The maximum amount of time, in microseconds, TNSR holds packet frames before it transmits. Default is 1000 microseconds.

dataplane vhost-user dont-dump-memory

When set, TNSR will not include vHost user interface shared memory segments in core files if a crash occurs. Default is unset.
