Errors during VM migration

Question

Hi,
I have an SCVMM 2012 R2 instance (with CU1), and when I perform a VM migration I get a status of Completed w/ Info
In the details pane of the Jobs window I have 9 errors and a warning every time
Error 23801 - No available connection to selected VM Network can be found
Error 23810 - There is no host NIC with required classification
Error 23806 - All available ports on switch extenstion has been used
Error 23808 - All available ports on port profile has been used
Error 23807 - The switch extension has reached maximum supoprted ports on this host
Error 23809 - The port profile has reached maximum support ports on this host
Error 23811 - Ports are not available for VM Subnet
Error 23825 - The virtual machine requires a logical switch connection and the host network adapter is not attached to a logical switch or operating sytem doesn't support logical switch
Error 23753 - The virtual machine or tier load balancer configuration requires an IP pool and there are no appropraite IP pools accessible from the host
Warning 23830 - Unable to find compliant logical switch
Even with all of these warnings the migrated VM works just fine.
In our environment we are using a layer 3 switch with VLANs, so I have a logical network using the 'VLAN-based independent networks' option, with two sites
Each site has an assoicated VLAN ID, and IP subnet
I've created a logical switch (without SR-IOV), using only the Microsoft Windows Filtering platform extension
The uplink on the logical switch is not a team, and has a port profile associated with the host group including all my Hyper-V hosts, and including all sites from the logical network
The virtual port on the logical switch has High bandwidth and medium bandwidth port classifications associated
I have VM Networks created for each of the sites on my logical network
The network configuration on my VM is as follows:
 Connected to a VM network, enable VLAN
  IP address is greyed out as Static IP (from a static IP pool) - This was configured as Dynamic at creation time as I do not use IP pools
  MAC address is dynamic
  Virtual switch - using the logical switch mentioned above and High Bandwidth classification
The hosts have a dedicated interface on a trunked network port for VM data. Available for placement is checked, used by management is not (as i have a dedicated interface for that)
It has the logical network mentioned above assigned, and all IP sites are shown with their VLAN IDs
I believe I have everything configured correctly (after all the VM works correctly regardless of which host is running it), but i still see these errors during a VM migration
Has anybody seen this before, or have any pointers to resolving them?
The hosts are Server 2012 R2 Datacenter and the VM is Server 2012 R2 Standard
Thanks,
Phil

I am also getting these errors when manually migrating machines between hosts. And indeed, the VM is moved and keeps working.
But when I try to put an host in maintenance, it instantly fails with:
Error (10434)
No suitable host is available for migrating the existing highly available virtual machines.
Not quite the same network setup, but running all Server 2012R2 and VMM2012R2.
In my production environment I do not have these issues, which is running Server 2012 and VMM2012SP1.
