I have an existing CentOS 6.9 VM running in Hyper-V on Windows Server 2008 R2. I want to migrate this machine to a new Windows Server 2016 installation. This is the last VM that will allow me to shut down the old server.
My problem is the eth0 network adapter is not found on the new server. The issue is further complicated because the VM then stalls during boot trying to mount a cifs share. Checking Google shows other complaints about the missing network adapter drivers, but the normal work-arounds are not helpful to me because of the boot problems.
I waited more than 8 minutes for the cifs mount to timeout and the VM to continue booting. At that point I was running up against the end of my maintenance window, and so I had to give up and re-start the VM on the old server.
I'm afraid I'm going to need to wait until I can plan a longer maintenance window that will allow time to disable the cifs mount on the existing VM, so I can then troubleshoot the network adapter on the migrated VM before re-enabling the cifs mount. It could be several months before I window like that opens to me.
Any ideas for a fix I could accomplish during a weekly 1 hour window, remember I'll need to allow about 20 minutes of that for just copying the 180GB vhd file to the new server?
