Good evening, I have a question about a strange problem when using KVM

Good morning...

I have
  "CPU Type": "Intel(R) Core(TM) i3-2120 CPU @ 3.30GHz",
  "CPU Virtualization": "vmx",
  "CPU Physical Cores": 1


I create the virtual machine. with these parameters.
   "max_physical_memory": 1024,
   "max_swap": 1024,


But when this virtual machine loaded with IO stream, the next thing is happening
 kthr      memory            page            disk faults      cpu
r b w swap free re mf pi po fr de sr lf rm s0 s1 in sy cs us sy id 0 0 0 13509588 6175344 0 135 0 0 0 0 0 0 0 0 129 18589 72236 28122 4 10 86

Ie we have a very strong memory leak. That does not disappear even when the complete removal of the virtual machine. Just reboot (hypervisor).

How do you know there is a leak rather than the system (ZFS amongst others) making use of the available RAM?
