This commit is from 05/29 no?
there were issues with that. But it should be fixed.
Do you still have the command-line issue with the last git?
See commit 80270a19685dd20eda017b0360c743b3e3ed6f57
Hi Fred,
This patch is to change bus which can be compatible with old version, right?
But I saw the current name is still different from old version.
The current name is: "virtio-serial-bus0.0"
The old version is: "virtio-serial0.0"
Is it possible to change it back to the old name?
Thanks. :)

Thanks,
Fred
