@mardonis200 This all looks good. What seems to be the problem? Is there a specific error you see?
This message is just a notify message:
Failed to set DNS configuration: Link lo is loopback device. -
when I boot vm guest and choose from FOG menu either:
“Perform Full host registration …”
or
“Quick Registration …”I get black screen with blinking cursor.
Thanks.

@mardonis200 If you get to the fog ipxe menu, then dnsmasq has done its job. Once at the fog ipxe menu dnsmasq is out of the picture. Selecting a menu item will have iPXE transfer bzImage and init.xz. Do you see this transfer or just the flashing cursor?
What computer is causing this problem? Is it just a specific model or all models?

I see transfer of bzImage & init.xy.
then see black screen with blinking cursor.physical host: Dell Latitude E7270 laptop
running fog server on VirtualBox. in “bridged adapter” mode
running ubuntu 22.0.4 client on VirtualBox in “bridged adapter” modeThanks.

@mardonis200 Please try other physical machines. As well increase the kernel log level to 7 in the FOG settings (web UI).
