Hi there,
I have a backup server running Proxmox as hypervisor. I have on physical 1Gbit NIC attached running as OVS bridge with several VLANs.
So far I run a TrueNAS and two loadbalancer (Ubuntu 20.04) VMs.
Both of my loadbalancer are running Keepalived and share one virtual IP (VIP) together with two Raspberry Pis (they were the origin of my loadbalancer).
When I was running Keepalived only on my Raspis I did not have any issues at all from a network perspective.
Yesterday when I created the loadbalancer VM I reconized that the VIPa failed from time to time: No ping, applications complied about lost connection to database backend.
So I shut them (temporary) down.
Today I run a backup of a loadbalancer VM to my local TrueNAS VM NFS store - worked like a charm.
As I wanted to copy the dump file to another machine I recognized that the network interface was also going down, it came up again, went down, and so on...
Any ideas what thing could cause such an issue?
