Hi,
I am currently booting a initramfs as the VM so that I later would be able to switch root to a filesystem disk that allows for larger storage and has other software installed that I want inside the VM.
I have started the simulate script with a few variants of the following line (Passing the virtio device was a guess since the virtio-net device is supported for networking for the VM. I have also tried to pass only the drive part but it has the same result.):
sudo ./simulate --extra-qemu-args="-device virtio-blk-pci,drive=drive0 -drive file=filesystem/testimage,format=raw,if=none,id=drive0"
However there are no devices appearing in /dev/ that seem to be the drive passed to qemu such as sdaX or vdaX. There is no output from running "fdisk -l" either.
So therefore I wonder if this kind of passthrough is supported by seL4? I have tried to find documentation that relates passing a disk to the VM in seL4 but have not found anything yet. This was done for the qemu-arm-virt platform if that has some significance regarding platform support.
Hi Olof,
Do you see the device come up if you perform `lspci` in the guest? The PCI bus should be being passed directly through to the guest by default, so adding a virtio-blk-pci should also get passed through. What commands do you use to create the testimage?
