Container created from PVA has tcpsndbuf, tcprcvbuf, othersockbuf and dgramrcvbuf set to limited number

APPLIES TO:
  • Parallels Cloud Server
  • Parallels Virtuozzo Containers
  • Parallels Server
  • Parallels Virtual Automation 4.6

Symptoms

When creating a container via Parallels Virtual Automation Management Node it always has tcpsndbuf, tcprcvbuf, othersockbuf and dgramrcvbuf limits configured even though these limits were not set during container creation wizard.

Cause

This behavior was needed for Parallels Virtuozzo Containers for Linux prior to 4.7. With Parallels Virtuozzo Containers 4.7, Parallels Server Bare Metal 5.0 and Parallels Cloud Server it is not needed, because with vSwap these parameters are set to unlimited by default. This behavior is corrected in Parallels Virtual Automation 6.0.

Resolution

Upgrade Parallels Virtual Automation Management Node to the latest version available:
112297 Parallels Virtual Automation builds, releases, and supported virtualization products
