<![CDATA[Xen VMs & elrepo kernel]]>I have been unable to get elrepo kernel 5.14 installed and booting on my CentOS 7/8 XCP VMs.
I can however get the Kernel installed on other platforms just not Xen (xcp) VMs.
Is anyone having this issue or heard anything about it?

@indyj May this is your issue? https://elrepo.org/bugs/view.php?id=1137&nbn=1

For those who install the kernel-ml from Elrepo: I tested this on all my CentOS 7/8 VMs: The results were mixed, the procedure worked on about half of them. Proceed with Caution.

Update:
This same issue has found its way into Fedora 34 in the stock kernel. No special repos, just "dnf update" and it happened. Could this affect the entire 5.14 series?

Never heard of this. What's the issue? Are you in HVM or PV mode for those guests?
