Reports posted look good for me. Config should provide the best available performance for cloud VM (L2) on Compute Node.
1. Please, remind me what goes wrong from your standpoint ? 2. Which CPU is installed on Compute Node && how much RAM ? Actually , my concern is :- Number_of_ Cloud_VMs versus Number_CPU_Cores ( not threads) Please, check `top` report in regards of swap area size.
