| Ladi Prosek | 2016-10-18 15:28:10 UTC | Doc Text | Cause: The fsgsbase and smep CPU flags are not properly emulated with old host CPUs. Consequence: Windows operating systems may fail to boot when running on a host with an old CPU and the fsgsbase or smep CPU flags enabled on QEMU command line. Workaround (if any): Do not enable fsgsbase and smep if the host CPU does not support them. Result: The guest OS will successfully boot. | |

Result: The guest OS will successfully boot. | Booting virtual machines with the "fsgsbase" and "smep" flags on older host CPUs fails The "fsgsbase" and "smep" CPU flags are not properly emulated on certain older CPU models, such as the Intel Xeon E series. As a consequence, using "fsgsbase" or "smep" when booting a guest virtual machine on a host with such a CPU causes the boot to fail. To work around this problem, do not use "fsgsbase" and "smep" if the CPU does not support them. |
