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 onlyin an OVS switch type cluster.
If you mean Native Open vSwitch as described here we don’t use it.
Current setup is simple 2-node and unfortunately I'm not aware of all deep details of oVirt networking.
Since oVirt uses KVM as underlying technology I assume it uses bridged networking to connect VMs and physical interfaces.
Each our server uses 2 Ethernet connections, 1 for internal LAN 192.168.0.xxx and 2nd for DMZ 192.168.1.xxx.
If so I assumed that it could not be a problem to bridge VM to external IP via 3rd Ethernet using oVirt networking.
May be its enough to turn on “isolated port” and VM Interface Profile to “clean-traffic”?
Please correct if I'm wrong here
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
