some questions about LegoOS

[anoyiuhu]

Hi, @lastweek

During the process of deploying LegoOS, I have some questions and hope to get your help.

1. According to GitHub ReadMe, the LegoOS can use RoCE, however, the RoCE has no lid or lid is 0( according to ibstat output). If I want to use RoCE, what should I do to set the value of Lid.
2. I also want to use VM to deploy processor and memory node, but I found that the VM console becomes "black screen"(no output) when I switched to LegoOS kernel. I use virt+qemu. It seems that I should set some configurations such as https://github.com/WukLab/LegoOS#442-setup-serial-connection option1. I don't the meaning of source path='/root/LegoOS-ttyS0'/. My machines don't have such ttyS0 file.

Looking forward for your reply.

Best regards!
