chris_netsmart Posted August 11, 2021 Share Posted August 11, 2021 (edited) I am trying to build a VM machine within unraid and I am running into muiti issues and I can't see why. for starts when I create a VM for Windows or Linux and it get's to the formatting and installing the OS, but for some reason it informs me that it can't see the HD. I also see that when I create the VM template I am not able to choose BR01 for my Nic ? is there a reason why. I have attach a few screen shots of my Linux build template in the hope that you are can help me resolve this issue. I have also downloaded and tried a pre imaged machine " Home Assistant " this finfs the Hard drive and loads but at the end, when I try and connect to it, I discover that I have no network. Note: my IP range is 192.168.1.* and not 182.168.122.* can someone please help Edited August 12, 2021 by chris_netsmart Quote Link to comment

Hello, from your post, I am not sure that it is in the right forum section. Are you using a VM of Unraid in another system (ESXI or other) ? Or your Unraid runs on bare metal ? Quote Link to comment

Sorry I am trying to get a VM Guest to run on my Unraid server UPDATE: I have been able to get a Linux guest to up and running, but now I have a second question, my default IP address is 192.168.1.* but when I do a ifconfig I am getting a 192.168.122.* IP address I am able to ping out from my Linux VM Guest but as the IP address is different from my main IP range I am not able to ping the VM Guest. how do I resolve this ?

You need to use one of your network card and make a bridge (br0), and use in the vm br0 instead of virbr0, so to be on the same network of the host in the guest, i.e. 192.168.1.* Or you need to dedicate one of your network card for passthrough to your vm and set in the guest the 192.168.1.* ip.

I only have one NIC on the server and that is build to the motherboard when I go and have a look at Network settings within the VM, I am not offer the option to changed to a br0 so are you saying that I will need a second card in the server to allow me to create a br0 ? and if no how to do go about creating one, as at the moment I have no VM's within my environment.

chris_netsmart Posted August 12, 2021 Author Share Posted August 12, 2021 being doing some reading and tried the following but so far no joy.

Solution chris_netsmart Posted August 12, 2021 Author Solution Share Posted August 12, 2021 ok after some more reading, and googling I found this. that help Here to get to it, you will need to stop the array, then go to the settings, change it and then restart and then you will see the Br0 Quote Link to comment
