Hi
I have a problem with constantly changing interface eno1 status - every few minutes port go to down, and up after 3 second:

I was changed cable, but that's not it.
Before taking these screenshots, I started ubuntu live and for 1h the port did not change state.
Interestingly, port eno1 has a static address, and yet it accepts IP from DHCP every now and then.
Anyone got an idea what's going on here?
 
Hi,
I decided to scratch the problem because probably no one will give a ready solution :P
1. I eliminated the problem of physical connection - ethernet cable and sockets were definitely ok.
2. I did a downgrade from Proxmox 7.1 to 6.4 - without VM enabled there is practically no problem.
3. with VM enabled, there is an up/down problem on any type of network card driver.
It turned out that I have an e1000e network card which in combination with various Linux releases works badly or very badly....
4. solutions from the Internet like "ethtool -K eno1 gso off gro off tso off tx off rx off" did not give anything.
5. I bought a network card "Lanberg PCE-1GB-001" with Boradcom driver. I plugged it in, added it to /etc/network/interfaces, put in vmbr0 and everything works perfectly!
In short, you have an e1000e network card or one that dozens of forum posts = buy a tested network card and get it over with.
