Systems and methods for providing i/o state protections in a virtualized environment

A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause at least one machine to perform operations comprising:

• configuring, by a hypervisor, a processor to execute instructions corresponding to a guest of a virtual machine (VM), wherein the processor includes a plurality of registers;
• and
• detecting, by the hypervisor, a transition from the VM to the hypervisor, the transition including:
• specifying, by the guest, one of the plurality of registers;
• providing, by the processor, access to data stored in the plurality of registers, wherein data stored in a first register of the plurality of registers includes non-encrypted data, and wherein data stored in each non-specified register of the plurality of registers includes encrypted data;
• and
• receiving, by the hypervisor, the non-encrypted data.

A system comprising:

• a processor coupled to at least one non-transitory memory, the processor including a plurality of registers;
• a hypervisor that configures the processor to execute instructions corresponding to a guest of a virtual machine (VM), the hypervisor to detect a transition from the VM to the hypervisor, the transition including:
• specifying, by the guest, a first register of the plurality of registers, wherein a remainder of the plurality of registers is not specified;
• providing, by the processor, the hypervisor with access to data stored in the plurality of registers, wherein data stored in the first register includes non-encrypted data, and wherein data stored in the remainder of the plurality of registers includes encrypted data;
• and
• loading, by the hypervisor, the non-encrypted data.
