Dear all,
when running
sudo jailhouse enable configs/qemu-vm.cell
I get
JAILHOUSE_ENABLE: Invalid argument
The tracing console says
hypervisor/arch/x86/amd_iommu.c:329: returning error -EINVAL
meaning that the following condition fails:
327 /* Protect against accidental VT-d configs. */
328 if (!iommu->amd_bdf)
Therefore, apparently I have misconfigured some setting about AMD IOMMU.
However, looking at the documentation I have not found any AMD-specific setting.
Here is some further information about my configuration:
HOST:
- Linux distribution: Ubuntu 16.04.1 LTS
- Linux kernel: 4.4.0-36 x86_64
- Qemu version: 2.7.0
GUEST:
- Linux distribution: Linux Mint 18 Sarah
- Linux kernel: 4.4.0-36 x86_64
- Kernel boot param: memmap=66M$0x3b000000
- Run through the following command: qemu-system-x86_64 -machine q35 -m 1G
-enable-kvm -smp 4 -cpu
host,-kvm_pv_eoi,-kvm_steal_time,-kvm_asyncpf,-kvmclock,+x2apic -drive
file="Mint.vdi",id=disk,if=none -device ide-hd,drive=disk -serial stdio -serial
vc -s -net user,hostfwd=tcp::22222-:22 -net nic
Many thanks and best regards,
Claudio
