XCP vm fails to boot after newest kernel applied.

Greg_E

I'm running the same guest tools.

Could it be a processor related issue? I'm running AMD v1756b in my lab, haven't had time to try in production that is Intel Silver.

Greg_E Maybe it only affects Intel? That would be a new wrinkle. Perhaps other AMD users can confirm if the latest AlmaLinux 8 kernel runs fine on their AMD XCP-ng 8.3 hosts? Just read the above referenced RedHat bug report here: https://access.redhat.com/solutions/7116307 Sure enough, it says Xen + Intel in problem description. Check it out.

Greg_E according to the Knowledge base of Redhawks it is den Witz Intel CPUs. So you AMD isn‘t affected

According to https://access.redhat.com/solutions/7116307 the bug is solved, but I don't get newer Kernels on Rocky yet.

Sad that even this documentation is locked behind a Redhat account, I can only read part of the problem description. Not going to make an account because it really doesn't affect me right now.

Resolution
The issue has been resolved with the errata: RHBA-2025:4337. Hence, update the kernel to kernel-4.18.0-553.51.1.el8_10 to fix the issue.

id assume it arrives soon? I as well, haven't seen it yet.

Tried one of my Rocky's and still .50. I wonder where we can see the status of downstream fixes like that? anyone know? thanks.

This may sound stupid, but here goes...

Does Rocky need to update to .50 before it can update to .51?

I'd guess no, but I've been away from RHEL based stuff since the IBM rug pull. Only coming back because I may need it in the future as I jockey around trying to improve my paycheck.

Alma must have dropped everything to push this out. I wonder what Oracle is doing, guessing they were hit by this too. I'd guess Rocky has this out pretty fast, they know it is important.
