This is another blog in the series to give the Oracle VM community some additional information on the 3.4 release that we announced on March 24. This week, we are going to share a little more information on the Dom0 kernel enhancements that were delivered with this updated version of Oracle VM.
Modern Dom0 kernel
With Oracle VM 3.4 we updated the Dom0 kernel to Oracle Unbreakable Enterprise Kernel (UEK) Release 4, based on the 4.1 mainline kernel. This update brings performance improvements; and rapid driver availability and streamlined partner certifications with Oracle Linux and Oracle VM. The latest set of driver updates offered with this new kernel can be found in the Release Note for UEK Release 4.
Dom0 kernel updates on live systems
Ksplice updates for the Dom0 kernel used on Oracle VM 3.3 (UEK3) and Oracle VM 3.4 (UEK4) are now available. All Oracle VM customers with Premier Support for their x86 Servers will be able to access the Ksplice channel on ULN to take advantage of this Oracle technology to add important kernel updates and security patches without needing to live migrate VMs or reboot your Oracle VM Server.
The process to install the Ksplice Uptrack client and perform the live kernel updates is similar to the process for Oracle Linux since this is used for the Dom0 user space in Oracle VM. Please refer to the KM note on My Oracle Support for all the information you need to use Ksplice with your Oracle VM deployment. The document “Oracle VM: Using Ksplice Uptrack” can be found with Doc ID 2115501.1.
