Putting a VMM 2012 host with a 3rd party switch extension into Maintenance Mode fails with error 10434
When you try to put a Virtual Machine Manager host that has a third-party switch extension installed into Maintenance Mode you receive the following error message:
10434 No suitable host is available for migrating the existing highly available virtual machines.
This issue can occur if most of the ports on switch extensions and port profiles are being used.
To resolve this issue, take one of the following actions:
- Increase the maximum number of available ports on switch extensions and port profiles. There should be at least one available port for each virtual machine.
- Live-migrate virtual machines that are using switch extensions manually one by one before you put the host in Maintenance Mode.
