(rmapiAllocWithSecInfo enters with class 0xc57e, serverAllocResourceUnderLock returns 0x56 before the GSP-RM RPC at under-lock+0x447; _rpcAllocObjectPrologue exonerated); the guest's not-stripped nvidia.ko is a new live-debug instrument; gdb-stub hazards recorded (kill wedges the VM - detach-only recovery; stepi loops wedge the guest - prefer conditional breakpoints)

ALLOC_DEVICE reply status 5 (CORE_CHANNEL_ALLOC_FAILED) decoded by the LD_PRELOAD nvKms logger with a widened reply scan; the empty display capability notifier is the first missing piece (a live-gdb fill of SYS_CAP/SYS_CAPB flips the driver to the window path, proving numWindows>0 unblocks it); the residual wall is the vGPU-guest display-class rejection: nvRmApiAlloc(0xc57e) returns NV_ERR_NOT_SUPPORTED inside the guest kernel and never reaches the emulated GSP - the guest runs in vGPU mode where display/modeset classes are host-service-provided by design

enumerates on the emulated vGPU; vkCreateDevice fails in nvidia-modeset's ALLOC_DEVICE past the new NV0073 head/connector shim, residual wall = the display core/modeset channel objects; Xorg ScreenInit fails in nvidia-push's 10 s channel test with submissions=0 and unresolved X-channel VAs - the guest scanner serves CUDA clients only - plus a rank-0 counter-slot collision with a live CUDA client; EGL/glsi unchanged) and link the page from the README
