Hello, Here is a little series improving error reporting of protected VMs.
Thanks, C. Changes in v3: - dropped 's390x/pv: Check for support on the host'. This is already covered by the KVM capability. - in s390_pv_check() (patch 2) drop the call to s390_pv_guest_check() since init time has already checked the same conditions. However, to report an error when the machine is not protected and the kernel secure, we still need s390_pv_check(). Changes in v2: - dropped ConfidentialGuestSupportClass handler. The check is now done from s390_pv_init() which is called after memory and CPU initialization. This gives us a better chance to tune the limits correctly. - pv_max_cpus now computed from the available size of the response buffer of the Read SCP Info Service Call (Thomas) Cédric Le Goater (3): s390x/pv: Implement a CGS check helper s390x/pv: Introduce a s390_pv_check() helper for runtime s390x/pv: Move check on hugepage under s390_pv_guest_check() include/hw/s390x/pv.h | 2 ++ hw/s390x/pv.c | 64 +++++++++++++++++++++++++++++++++++++++++++ target/s390x/diag.c | 6 ++-- 3 files changed, 69 insertions(+), 3 deletions(-) -- 2.39.0
