Bug Description

KVM: Allow long kernel command lines for Secure Execution guests (s390-tools)

Description:

Originally, the kernel command line length was limited to 896 bytes, due to its fixed size in the kernel image. Recent kernels can support larger command lines by checking out the supported kernel command line length using a new field in the kernel image. This feature allows Secure Execution guests to use larger command lines.

Request Type: Package - Update Version
Upstream Acceptance: In Progress

Ideally this would be part of the next and upcoming s390-tools version that is planned to be the one for jammy anyway.
