Hi,
Hi,
I’m running oVirt 4.4.4.7-1.el8 and need to connect one of the VMs
straight to the ISP link via Ethernet cable.
oVirt already have 2 networks (ovirt mgmt local + DMZ).
Created new network provider and assigned to it available physical
interface of HP ProLiant, connected via cable to ISP switch with public IP.
By provider do you mean ovirt-provider-ovn? If so are you using OVS cluster
type? The physical interface connection for external networks work only
in an OVS switch type cluster.
Options of this network: (VM Network = on, Port Isolation = off, NIC
Type
= VirtIO, the rest are defaults).
VM is Debian 10.
Link works but with strange artefacts. If VM left being idle for a while,
it cant be connected or pinged from outside, until I initiate pings from VM
itself.
I have only 2 IPs from this ISP so I’m sure there are no IP address
conflicts.
Another port and public IP go to our VyOS router handling internal and DMZ
zone.
When this happens I would suggest to trace where the packets are getting
dropped.
How to fix this problem ?
Thanks in advance.
Andrei
