What the vendor recommends
We have pushed updates to both the Early Access and Normal update channels of XenServer 8.4. We recommend that customers update to the latest version from their chosen channel following the instructions at https://docs.xenserver.com/en-us/xenserver/8/update. However, customers should note that the AMD microcode update provided is only effective on systems where the system firmware ("BIOS") has been updated to a version that includes a fix for CVE-2024-36347. This may be marked in the firmware release notes by reference to the firmware containing âAGESA PI 1.0.0.4â or later. Customers who are uncertain about their firmware version are recommended to contact their hardware vendor.
