 Update:
 
 The described case for the physical machine is ZFS-related. 
 
 It is reproduced at ZFS Volume-based swap:
 
 (for example - da0 is empty disk):
 kldload zfs
 echo 'zfs_load="YES"' >> /etc/rc.conf
 zpool create swp /dev/da0
 zfs create -V 4G swp/swap
 zfs set org.freebsd:swap=on zwp/swap
 zfs set checksum=off swp/swap
 
 service zfs restart
 service zvol restart
 
 then repeat actions from How-to-repeat
 
 For VirtualBox a case - problems arise without ZFS. It seems, it is related 
 with inheritance kmem\* or other parameters from the master host
