I have been having a problem with my main server. It cannot hold "internet" for more than 15 minutes (or less). This has been happening for the last week. A little background is I have a Ubuntu 20.04 virtual machine running on Windows 10 via Oracle VirtualBox.
I share the WiFi connection with the host, and about every gig of data, or about 15 minutes, my host OS network just stops working. It says that it is connected to WiFi, but after every single troubleshoot, it says that the "Default Domain Name Server could not be reached" then resets the WiFi adaptor, and then the internet starts working again until the aforementioned case happens again. If I don't even start the VM, it takes longer to get the 1 gig of data, but eventually no internet again.
What I want to know is where the breakdown is happening. Is my WiFi nic bad? Is my router bad? Is the Oracle VM drivers screwed up somehow?
KVM - easy Network card NIC PCI pass through with virt-manager
with virt-manager, it is a breeze to select the PCI device (in this case enp3s0 NIC) for pass through to guest vm, in case the vm shall get it’s very own dedicated nic:
notice: the passed NIC dissapears from the ip -c a list of NICs on the server
