Something is not good:

class "KVM-vms" {
#    match if binary-to-ascii (16,8,":",substring(hardware, 0, 4)) = "1:52:54:0"
    match if substring(hardware, 0, 3) = 52:54:0;
    log (debug, binary-to-ascii (16,8, ":", hardware));
}

class "VBox-vms" {
#    match if binary-to-ascii (16,8,":",substring(hardware, 0, 4)) = "1:8:0:27";
    match if substring(hardware, 0, 3) = 8:0:27;
    log (debug, binary-to-ascii (16,8, ":", hardware));
}

class "VMware-vms" {
#    match if binary-to-ascii (16,8,":",substring(hardware, 0, 4)) = "1:0:c:29";
    match if substring(hardware, 0, 3) = 0:c:29;
    log (debug, binary-to-ascii (16,8, ":", hardware));
}

The pools are:

        pool {
            allow members of "KVM-vms";
            range 192.168.52.180 192.168.52.199;
            }
        pool {
            allow members of "VBox-vms";
            range 192.168.52.170 192.168.52.179;
            }
        pool {
            allow members of "VMware-vms";
            range 192.168.52.160 192.168.52.169;
            }
        pool {
            range 192.168.52.21 192.168.52.29;
            deny members of "KVM-vms";
            deny members of "VBox-vms";
            deny members of "VMware-vms";
            }

I started a VBox and a VMware VM and they got IP
from the last (.21-.29) pool! Of course there aren't any
log in the messages file (log command in class).

Do you know what is the problem?
