Live Migration Never Finishes With UEK3 And ASM On Oracle VM (Doc ID 2202426.1)

Last updated on NOVEMBER 10, 2016

Applies to:

Oracle VM - Version 3.3.4 and later
Information in this document applies to any platform.

Symptoms

Live migration (xm migrate -l) seem to work OK with RAC on OVM 3.2+, however,as soon as an ACFS(ASM Cluster file system) volume is used it seems to stall indefinitely.

For kernel UEK3 (3.8.13-118.8.1), it reported 'Freezing user space processes ...' in dmesg_uek3 before process 3235 in D status.
