Hi,
I have a Proxmox 6 server at SoYouStart https://www.soyoustart.com. I've
been running a server there for years, running Proxmox 4. Instead of
upgrading, I backed up all my VMs, did a fresh Proxmox 6 install, and
restored my VMs. It works well, except for NFS, but that's another topic.
Every 24 hours, vmbr0 disappears. The SoYouStart staff can't ping the
machine, assume it's gone down, and hard reboot the server. 24 hours
after it's up, the cycle repeats. I'm not sure what is going on.
One weird thing, is that vmbr0 isn't configured in Proxmox, SoYouStart
has it configured some other way. Could this be part of the problem? It
looks like vmbr0 gets its IP via DHCP. (Yup, check in
/etc/network/interfaces)
