Oracle VM Server Domain-0 Kernel Updates


In some cases, Oracle VM customers may require an updated kernel for their Oracle VM Server Domain-0 (Administration Domain).  This may be to receive updated hardware support, improved performance, or to get additional security patches.  Installing the latest Unbreakable Enterprise Kernel Release 2 (UEK2) on your Oracle VM Server Domain-0 is fully supported by Oracle.

Current list of fixed bugs in UEK2-latest kernel:
    BUG 17556598 - UPDATE HBA DRIVER IN ORACLE VM SERVER 3.2.6
    BUG 17908583 - BACKPORT ORABUG-17630145 TO ORACLE VM: XEN_SPIN_LOCK_FLAGS

Support for Third Party Kernel Modules

Any third party kernel modules in use on Domain-0 with Oracle VM 3.2.x will require recompile for support with the kernel provided here. This is due to the change in kernel ABI between the GA version and the ARU provided version. This is a one-time-only change, and future updates to the Domain-0 kernel will continue to maintain stable kernel ABI for third party modules.
