Networking stops randomly running Ubuntu Hirsute on Virtualbox

dld2517 · 11-24-2021, 12:26 PM

I recently installed a VDI of Ubuntu 21.04 Hirsute that I downloaded from OSBoxes.org. I have run a large number of VM's in Virtualbox and have not experienced this problem before. Essentially what will happen is the network interface will stop responding and using systemctl status enp0s3 will report that the device is loaded and inactive(dead).

A ping test will show the following:

Code:

$>ping 127.0.0.1
PING 127.0.0.1 (127.0.0.1) 56(84) bytes of data.
64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time-0.022 ms

$>ping 8.8.8.8

^C
--- 8.8.8.8 ping statistics ---
2 packets transmitted, 0 received, 100% packet loss, time 1005 ms

Restarting the network service will restore connectivity immediately and will result in successful pings outbound:

Code:

systemctl restart systemd-networkd

Hi.

Got enough specs, to keep up with the new stuff or could they be wearing out?

Virtualbox should have logs too, e.g:

So far the specs look fine. The server is under 0 load when this happens it is just running in a VM on my laptop. i5 processor with 8 GB memory, windows 10 VM. Load: 0% and the network interface goes down. It may be related to leaving the VM process and moving to another one. As long as I keep interacting things seem to keep working.

When I'm in Virtualbox, each machine shows 3 little dots and lines to the right. Expanding for: details, screenshots and logs... something may show up in those log tabs?
