Check kernel command line to see which kernel loaded?

cat /proc/cmdline

Below log shows ACRN hypervisor isn’t launched successfully, and no hv log，

 

 

 

Thanks

Hi 
I'm using a mmio for the uart setting and I show shell prompt.  
However, I'm not sure this is the SOS or the host clear linux. 

dmesg | grep ACRN  gives me below logs...

ACRNTrace : acrn_trace : not support acrn hypervisor!
ACRN HVLog : acrn_hvlog_init
ACRN HVLog : Failed to setup acrn_hvlog_cur_0, errno -19

What is error number 19, and do you have any idea to clarify root cause?
(I couldn't find this messages from the hypervisor source codes)

Thanks 
Taekyoung Kim
