EfLoW installation: Failed to acquire IP address for virtual machine about iotedge-eflow HOT 4 CLOSED

@FMauroy,

Could you open the Hyper-V Manager and check if the EFLOW VM has an assigned IP in the networking tab?
If no IP is assigned, could you try restarting the VM?

Have a look at this issue #9

Sounds very similar to some of the issues we were having. The link includes a workaround for the IP issue, but you might encounter others further down the line.

@FMauroy,

It appears that the VMSwitch which the VM was attempting to use is not able to get an IP address. On physical hardware this can be caused by a misconfigured VMSwitch that is attempting to use an inactive network connection. I do not know the specifics of your particular hardware, but I had this occur on my Intel NUC which has two wired connections in addition to a wireless connection. Once I configured my VMSwitch to use the port that I had connected to the network it resolved this issue for me.

Please run the following commands in an elevated PowerShell session.

This will tell you which VMSwitch your EFLOW VM is using as well as how it is configured. You can modify the configuration of the VMSwitch using Hyper-V Manager using Virtual Switch Manager. If you are not familiar with Virtual Switch Manager, this is a pretty decent tutorial .

Please let us know how it goes.

Thanks everyone for you quick replies :-)

I double checked all connections, and didn't find anything wrong. It should have worked. So in the end, I rebooted the host, and it worked right away... Maybe Hyper-V was a bit lost and the reboot set everything straight. I should have rebooted before posting.
