Remove nic host with id: null

[poli1025]

problem

The issue we are experiencing is that when attempting to remove a network interface in KVM while the VM is powered off, the operation fails with the following error: 'Host with id: null not found.' When the VM is running, the interface can be removed without any problems.

versions

ACS: 4.20.0
SO: Ubuntu 24.0.4

Steps to reproduce the issue:

1. Power off the VM in KVM.
2. Attempt to remove a network interface from the VM configuration.
3. The operation fails and the following error is returned: "Host with id: null not found".
4. If the same action is performed while the VM is running, the network interface can be removed successfully.

Yes, I have CPU capping enabled. So, if I disable the CPU cap in the service offering, it should work, right?"

I tested with CPU CAP disabled and it works correctly.
