2022-04-06 04:31:34 Po-Hsu Lin description [Impact] vmx_ldtr_test in ubuntu_kvm_unit_tests will fail with:     FAIL: Expected 0 for L1 LDTR selector (got 50) It's a test for commit afc8de01 "KVM: nVMX: Set LDTR to its architecturally defined value on nested VM-Exit" According to Intel 64 and IA-32 Architectures Software Developer’s Manual, L1's LDTR should be 0 after an emulated VM-exit from L2. [Fix] * afc8de01 "KVM: nVMX: Set LDTR to its architecturally defined value on nested VM-Exit" We already have this patch in Jammy. This patch can be cherry-picked into F/F-OEM-5.14/I. But backport is required for Bionic, as the code snippet for nested KVM haven't been split out to vmx/nested.c (55d2375e KVM: nVMX: Move nested code to dedicated files).
