KVM can't support more than one address space per CPU; if you try to create more than one then cpu_address_space_init() will assert.
The Arm CPU realize function wasn't checking for the combination of KVM and various features that might need multiple address spaces, so it would just blunder on and hit the assertion failure for command lines like: qemu-system-aarch64 -enable-kvm -display none -cpu max -machine raspi3b qemu-system-aarch64 -enable-kvm -display none -machine mps3-an524 This is https://gitlab.com/qemu-project/qemu/-/issues/528 This series adds the missing checks. It also fixes the raspi board code to not assert when CPU creation fails, and removes a now-duplicate check from the virt board code. thanks -- PMM Peter Maydell (3): raspi: Use error_fatal for SoC realize errors, not error_abort target/arm: Avoid assertion trying to use KVM and multiple ASes hw/arm/virt: Delete EL3 error checksnow provided in CPU realize hw/arm/raspi.c | 2 +- hw/arm/virt.c | 5 ----- target/arm/cpu.c | 23 +++++++++++++++++++++++ 3 files changed, 24 insertions(+), 6 deletions(-) -- 2.20.1
