Trade-offThe trade-off versus gVisor is that microVMs have higher per-instance overhead but stronger, hardware-enforced isolation. For CI systems and sandbox platforms where you create thousands of short-lived environments, the boot time and memory overhead add up. For long-lived, high-security workloads, the hardware boundary is worth it.
Descriptor attributes: The Type, DPL, S (system/user), and Present bits from the segment descriptor being loaded, held in a register called PROTUN. In a few cases, the Test PLA takes the 16-bit selector (segment register value) as input instead.
