[PATCH RFC v1 2/2] i386: reorder kvm_put_sregs2() and kvm_put_nested_state() when vCPU is reset

Setting nested state upon migration needs to happen after kvm_put_sregs2() to e.g. have EFER.SVME set. This, however, doesn't work for vCPU reset: when vCPU is in VMX root operation, certain CR bits are locked and kvm_put_sregs2() may fail. As nested state is fully cleaned up upon vCPU reset (kvm_a

[PATCH RFC v1 0/2] i386: KVM: Fix 'system_reset' failures when vCPU is in VMX root operation

It was discovered that Windows 11 with WSL2 (Hyper-V) enabled guests fail to reboot when QEMU's 'system_reset' command is issued. The problem appears to be that KVM_SET_SREGS2 fails because zeroed CR4 register value doesn't pass vmx_is_valid_cr4() check in KVM as certain bits can't be zero while in
