Bad NFS I/O Performance For Guest VM On Oracle VM Server 2.2.2 Which Use Intel 82599EB NIC
Last updated on MARCH 08, 2017
Applies to:Oracle VM - Version 2.2.2 to 2.2.2 [Release OVM222]
A cluster which worked well under Oracle VM 2.2.1 has abysmally-poor performance under Oracle VM 2.2.2; for example, shutdown of the Oracle Database, which uses DirectNFS, may take more than 30 minutes. Also copying large files takes an inordinate amount of time.
Deploy a guest VM from Oracle VM Server 2.2.1 to Oracle VM Server 2.2.2 and observe the performance degradation. No changes are required to the Oracle VM guest itself, just move it to an Oracle VM Server 2.2.2 cluster.
