Subject: [PATCH 0/4]: kvm-unit-test: nVMX: Test deferring of error from VM-entry MSR-load area
Date: Mon, 14 Oct 2019 20:16:29 -0400 [thread overview]
Message-ID: <20191015001633.8603-1-krish.sadhukhan@oracle.com> (raw)
Patch# 1: Replaces hard-coded value with instruction length read from VMCS
field.
Patch# 2: Adds an extra check to __enter_guest() so that it can distinguish
between VM-entry failure due to invalid guest state and that due to
invalid VM-entry MSR-load area.
Patch# 3: Verifies that when VM-entry fails due to invalid VM-entry MSR-load
area in vmcs12, the error is deferred and caught by hardware when
it is done processing higher priority checks such as guest state etc.
This patch also verifies that when VM-entry fails due to invalid
VM-entry MSR-load area in vmcs12, MSRs that were loaded from that
MSR-load area are rolled back to their original values.
Patch# 4: Replaces hard-coded value with corresponding #define.
