Re: [Qemu-devel] x86 VMCS guest interruptibility state save/load

[Hang Yuan]

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,
Henry
