My Ubuntu Server VM was working perfectly and had its own DHCP IP on the network.

 

Today, I added an "Unraid Share" passthrough and the NIC disappears on boot. If I remove the share and generate a new MAC address, the NIC reappears and I get an IP on boot.

 

Not sure how to fix?

Just wanted to bump this, I haven't been able to figure it out yet.

 

So just to reiterate:

 

- When unraid share is not passed through, networking works, enp1s0 exists and the VM receives an IP from DHCP.

- When unraid share is passed through, networking fails, enp1s0 does not exist and the VM does not receive an IP from DHCP.

 

I just can't figure out what the conflict is.

 

VM XML's attached with and without share passed through.

@torch2k I have a extra line for an alias in the xml. Not sure if you need it, but worth a try.

    <filesystem type='mount' accessmode='passthrough'>
      <source dir='/mnt/user/backups/'/>
      <target dir='backups'/>
      <alias name='fs0'/>
      <address type='pci' domain='0x0000' bus='0x06' slot='0x00' function='0x0'/>
    </filesystem>

 

Hi there and thanks for contacting us via support.  I will need to try and recreate this issue internally, so please bare with us.  That said, and not that this is an excuse for functionality not working, but why are you using the share method?  Generally speaking, we've had better results both with stability and performance by simply mounting an SMB share within the VM to the host.

It actually never crossed my mind to use that method. Perhaps the SMB method would work well within a VM, but I've been having a pretty miserable time with SMB lately, actually (see my others posts). I'll try that method and see if it will get me up and running. Perhaps unique to my issue is that the VM in question is running off of a pass-through disk. Accessing the Unraid shares is vital in this scenario so that I can backup files off of the VM and onto the protected array.
