2. Run the following commands to get stats:
   
   RAM usage

   # virsh dommemstat KVMID
   
   actual 1048576
   swap_in 0
   swap_out 0
   major_fault 163
   minor_fault 129424
   unused 908944
   available 1015968
   usable 858980
   last_update 1649081142

   # virt-df -a /dev/solusvm/KVMID_img -h
