Public bug reported: Hardware diagnose data (diag 318) of KVM guest kernel cannot be handled. Fix needed to enhance problem determination of guest kernel under KVM
Solution provided by Collin: All patches are provided to enable the DIAGNOSE 0x318 problem determination aid for a QEMU guest. Analogous KVM patches are required. This solution required the prerequisite Extended-Length SCCB patches as well. I've applied a bugfix related to resetting the diag318 to one of the patches (one line fix -- upstream conversation here: https://lists.gnu.org/archive/html/qemu-devel/2021-11/msg03618.html) ** Affects: linux (Ubuntu) Importance: Undecided Assignee: Skipper Bug Screeners (skipper-screen-team) Status: New ** Tags: architecture-s39064 bugnameltc-195467 severity-high targetmilestone-inin2004 ** Tags added: architecture-s39064 bugnameltc-195467 severity-high targetmilestone-inin2004 ** Changed in: ubuntu Assignee: (unassigned) => Skipper Bug Screeners (skipper-screen-team) ** Package changed: ubuntu => linux (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1953338 Title: [UBUNTU 20.04] KVM hardware diagnose data improvements for guest kernel - qemu part Status in linux package in Ubuntu: New Bug description: Hardware diagnose data (diag 318) of KVM guest kernel cannot be handled.
