[Xen-devel] run xl toolstack on hikey board

[Chenxiao Zhao <chenxiao.zhao@xxxxxxxxx>]

Hi,

I have followed xen wiki to get xen hypervisor and dom0 run on hikey board. 

when I try to run xl command to list all the domain in dom0, the command line get stuck and even ctrl+c can not terminate it. I used strace and found the last system call is write data to xenbus and it does not return. 

How could I determine what the issue is and how to solve it?

Thanks.

Attached the log, last line was the place where got stuck.
