Hello everyone I found kvm host from the code
https://github.com/apache/cloudstack/blob/main/plugins/hypervisors/kvm/src/main/java/org/apache/cloudstack/utils/linux/MemStat.java#L58 Available memory = free memory + cache memory (Is Buffers memory missing here) /proc/meminfo in the linux kernel has already calculated the Available memory for us, why not use it directly? -Jerry
