VM Migration Failed. CloudStack 4.22.1.0+XCP-NG 8.2.1 #13721

problem

Please help me figure out the reason for the virtual machine migration error.

The VM is started and it's connected to L2 network. When I try to migrate the VM to the another host of the pool I get an error "Unable to support this type of network broadcast domain: null". The same situation with some other VMs wich are connected to a VPC network.
At the same time, some other VMs of the same pool connected to other L2 networks migrate without problems.

versions

CloudStack 4.22.1.0+XCP-NG 8.2.1

The steps to reproduce the bug

1. Create L2-network with some vlan-id;
2. Connect a VM to L2-network;
3. Statr the VM
4. Migrate the VM to another pool's host
