Cannot install 6.0.18 or 7.9.20 and 7.0.16 is unstable with a ridged network 7.0.14 is normal and working

[George Kasica]

I tried to upgrade 7.0.16 to 7.0.18 and 7.0.20. Both failing stall with errors and say they’re rolling back, and no changes have been made. In reality, my original 7.0.16 is gone. Reinstalling it leads me to the BSOD when I run in bridge mode. If I start the VM in NAT and switch to bridged, everything will be stable at 7.0.16. It's not a good option if the system reboots automatically for some reason. Neither VM will come back up set to Bridged, just endless reboots. This takes our mail servers offline until someone can get on the system and remove the auto-starting VMs from the start shortcuts, boot vm-manager, change the setting to NAT, restart the VMs, and then set the VMs to bridged. I'll link the ticket we had open here: See Question ​https://forums.virtualbox.org/viewtopic.php?t=111418 ​https://forums.virtualbox.org/viewtopic.php?t=112012
