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
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
- 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.
