In summary, sounds all non-register guest states in VMCS structure are
not saved in snapshot. I don't understand why they don't need to save in
snapshot and load from snapshot to construct VMCS. Does anyone have any
idea?
Thanks,

Hello all,
When I read QEMU and KVM codes on saving/loading snapshot, I don't
find the interruptibility state in x86 VMCS structure is saved and
loaded in QEMU though KVM supports getting/setting this field
from/into VMCS. (No "env.interrupt.shadow" in QEMU
vmstate_x86_cpu.fields.) I understand it may cause guest-state error
if this field is not restored but other registers or VMCS fields are
restored. Do you think it's a valid issue?
Thanks,
Henry
