Now that the CPU realize function will fail cleanly if we ask for EL3 when KVM is enabled, we don't need to check for errors explicitly in the virt board code. The reported message is slightly different; it is now: qemu-system-aarch64: Cannot enable KVM when guest CPU has EL3 enabled instead of: qemu-system-aarch64: mach-virt: KVM does not support Security extensions We don't delete the MTE check because there the logic is more complex; deleting the check would work but makes the error message less helpful, as it would read: qemu-system-aarch64: MTE requested, but not supported by the guest CPU instead of: qemu-system-aarch64: mach-virt: KVM does not support providing MTE to the guest CPU Signed-off-by: Peter Maydell <peter.maydell@linaro.org> --- hw/arm/virt.c | 5 ----- 1 file changed, 5 deletions(-)
