Migration stales after network driver operation: pre

I would like to migrate one VM from one host to another one. The migration starts but then just hangs after network driver operation: pre.

Mon Aug 12 20:43:11 2019 [Z0][VM][I]: New LCM state is MIGRATE
Mon Aug 12 20:43:12 2019 [Z0][VMM][I]: Successfully execute transfer manager driver operation: tm_premigrate.
Mon Aug 12 20:43:17 2019 [Z0][VMM][I]: ExitCode: 0
Mon Aug 12 20:43:17 2019 [Z0][VMM][I]: Successfully execute network driver operation: pre.

What should happen next and why does it stop here?

It should then run:

  • migrate vmm
  • clean vnm (source host)
  • post vnm (dest host)
  • tm tm_postmigrate

Try to find the stuck process via ps (you should be able to filter it by the vm name), kill it and check the log to know where it got stuck.

You mean the same log from where I already have the output from before? Or another one on the sending host?

The log is located on the frontend. It is the same log you are seeing right now

OK. Thanks. I will try to get it resolved with this information.
