get-reg-list test is used to check for KVM registers regressions during VM migration which happens when destination host kernel missing registers that the source host kernel has. The blessed list registers was created by running on v6.5-rc3 Signed-off-by: Haibo Xu <haibo1.xu@intel.com> Reviewed-by: Andrew Jones <ajones@ventanamicro.com> Signed-off-by: Anup Patel <anup@brainfault.org>
