Which Interrupt Vector for Hypervisor Privelege Interrupt?

Which interrupt vector is taken when s/w attempts to access hypervisor resource while in user/guest mode?

 

P4080 Ref Manual, Section 1.2.3.2, "Guest Supervisor State Considerations"

 

"Attempting to access hypervisor privileged resources and instructions will cause embedded hypervisor
privilege interrupts which the hypervisor can service on behalf of the guest to provide appropriate
emulation"

 

P4080 Ref Manual, Section 8.8, "Interrupt Definitions"

 

In Table 8.4, IVOR 41 is described as "Embedded Hypervisor Privilege"

 

Is IVOR41 invoked when use/guest code attempts to access hypervisor resource?

 

Or is it another interrupt, perhaps IVOR6 Described as "Program/Privileged"?
