Why does Bonding always load only 1 DEBIAN interface?

Hello, the scheme is as follows, there are 4 gigabit interfaces, they are combined into bonding and then bridged into a KVM virtual machine, but when you download something to this machine over the network or jump from there, only 1 out of 4 interfaces is always loaded, why? At the moment, it costs mod 2 xor, if I understand the manual correctly, it should give a free interface for each new connection, but this does not happen.
cat /etc/network/interfaces

I advise you to do this:

bond-mode 802.3ad
bond-miimon 100
bond-lacp-rate 1
bond-slaves none

Another good option to try:
But 802.3ad is the most critical, both from the server side and from the switch side.

@rostel

what is configured on the switch is known?
it is desirable to apply a scheme for connecting to the DC network

The information provided is not enough to answer the question.
How is the bonding on the other side set up, where do the cables go?
Does the kernel give any messages about the bonding operation?
dmesg | grep bond
