Have tried creating a VM with a variety of settings and get the same error each time.  I've tried enabling and disabling PCIe ACS override, I've tried using SeaBIOS and OVMF as well as several different OS ISO's (Ubuntu server 15.04, lubuntu, slack) with no luck.  Same message every time.  I'm not trying to pass-through any devices....yet.  What am I doing wrong?

I have run Unraid 6 with VM's on this exact hardware.  Only thing that changed was Unraid config.  I started fresh with my flash drive.  Things had become a bit messy after 5 or so years of running various plugins, docker containers, vm's and a multitude of shares.

 

Any ideas?

Have you set up a bridge?

yes!  I didn't try disabling that, although it worked before.  I'll disable it and see if that helps.

I wouldn't have thought disabling it would make any difference, if anything, less likely to work...

 

Changed anything in your BIOS?  Might be worth checking...

That worked.  Didn't disable the bridge, just told the vm to use the default bridge instead of br0.  Do you know the cause/solution?

 

Thank you!

So you're using virbr0?  Only problem with that is I think you get an IP from a different subnet than the rest of your LAN

correct, need to get it back to br0 for networking.  When I change it back to br0, the vm starts but the same errors pop up in the logs.

And you've definitely gone to settings ==> network settings and created the bridge?

What happens when you start the VM? Do you see it booting?

Please post a screenshot of the VM's template and the XML.

And be sure as CHBMB says to check that you did create the br0 bridge.

 

1. Yes, bridge is definitely created and is br0

2. The VM starts to boot.  I get the bootloader screen but then vnc exits and the log shows

Try setting the memory to the same amount in both min and max if you have enabled advanced mode in the template.

You have set the current memory to only 262 MB it looks like. That is too little. Set it 2GB and try again.

Ha! More like glasses 

Ill try that.  I set initial to 256mb and max to 4 gigs.

Did you guys end up finding a fix?
