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 no changes made. Reality my original 7.0.16 is gone. Reinstalling it leads me to the SOD when I run in bridge mode. If I start the VM in say NAT and then switch to bridged every thing is stable on 7.0.16. Not a good option if the system reboots automatically for some reason. Neither VM will come back up u set Bridged just endless reboots. Which take our mail servers off line until someone can get on the system and remove the auto stating VMs from the start shortcuts, boot vm-manager, change the setting to NAT, restart the VMs and then set the vms to bidged. I'll link the ticket we had open here ​https://forums.virtualbox.org/viewtopic.php?t=112012 ​https://forums.virtualbox.org/viewtopic.php?t=111418
