Hi Justin,
I searched for the ovs in mikelangelo-project repo, and I found the
virtio-ivshmem driver. I used diff and ported the patch to the latest ovs
master branch on my local computer.
The console prints:
OSv v0.24-510-gc604860
...
[E/42 virtio]: Wrong virtio dev id 1110
Assertion failed: status == true (drivers/virtio.cc: virtio_driver: 35)
I see that in drivers/virtio.cc:112 the dev_id can only sit between 0x1000
and 0x103f, but ivshmem dev_id is 0x1110. I commented this check and
encountered another problem. I was wondering if the virtio-ivshmem has been
tested or not.
