I can debug xen using console connections. However, HVM nested xen seems to not support 'xl console'. Even though I set the console according to http://www.dedoimedo.com/computers/xen-console.html, it still cannot output xen related infomation. Any suggestions?

Nonsense - it works.
Did you set on Xen's (the nested one) com1=115200 console=com1?

Yes, I thought it is console=ttyS0. Actually, that should be to dom0 kernel. Thanks.

No. On the dom0 kernel it should be console=hvc0. Unless you only want to
see the Linux kernel output but not the hypervisor?

FYI, 'console=com1,115200,8n1' is working in my machine.
