I see.

I see. If I only configure com1 as you suggested, it works as well.
(Maybe it  just happened to work with the previous setting I had.)

So the following xen command line works:
placeholder dom0_mem=8192M,max:8192M dom0_max_vcpus=8 sched=credit
com1=115200,8n1,pci console=com1,vga

Thank you again for your help!

Best regards,

Meng
