kvmtop can't collect memory of VM correctly.
as below, some of VMs are 0 for ram_total, ram_used.

Also, I want to know meaning of ram_vsize and ram_rss. Would U let me know it ?
Is there any workaround to get ram_total / ram_used ?

UUID    name    ram_total       ram_used        ram_vsize       ram_rss ram_minflt      ram_cminflt     ram_majflt      ram_cmajflt
