  guests (s390-tools)

Status in Ubuntu on IBM z Systems:

  Fix Released

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
