user VM Management from SOS VM


yogesh@...
 

Hi All,
    I have ubuntu 18.04 Service OS VM with ACRN hypervisor installed. I have generated Ubuntu UOS VM and have launched Ubuntu 20.04 UOS VM. 
Unfortunately at this time I dont have second monitor to assign to uos vm nor having serial cable to connect to console of uos. 
     I have tried to installed openssh-server into uos vm image and assigned ethernet controller in launcher script through Web interface(app.py). 
But unfortunately I could not able to see its IP address.

now enough free pages are reserved!
 
try to setup hugepage with:

Could you please let me know what could be the other ways by which we can know messages or status of uos VM.
