Hi
I've started having a strange problem the last couple of days with my VMs, I use both VMWare Workstation and VirtualBox on my Fedora 33 system and recently the network connectivity inside my VMs stopped working after some point.
I installed an Ubuntu VM, in VMWare. and was using it for several days without issue and then yesterday I booted up the VM and I could not access the outside work from within my VM. As far as the VM was concerned everything seemed fine, it had an IP address in the expected range there was just no connectivity. I needed to do some work in a Debian based machine so just quickly stood up a new VM, this time Debian Buster. As before it worked fine. However this morning I booted up the VM and encountered the same problem. With this VM I had created a snapshot shortly after standing it up when i knew it was working, so I reverted the machine to the snapshot and again I had no connectivity within the VM.
I then tried VirtualBox, I stood up a Debian Buster VM and booted into it, it worked fine. At some point later network operations stopped working like with VMWare.
Any idea what could cause networking to stop working within my VMs?
Cheers
Adam
