Thought I'd ask here before hitting up support.

I have a brand new install of Proxmox 7 and Virtualizor. Storage is LVM.

I can use Virtualizor to install an OS using Proxmox QEMU, but the network interface isn't working.  I'm using virtio and using a different IP than the master Proxmox server. BTW, the server is not in a cluster, it is standalone.

I can ping the guest IP from the host, but not from outside of the network.

I have a lot of experience with Virtualizor and Xen and don't have any issues.  This is my first try at using Proxmox.

The Proxmox setup didn't give me a lot of options.  What am I missing?

Ethernet on the guest:

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:16:3e:ed:9f:ea brd ff:ff:ff:ff:ff:ff
    altname enp0s18
    altname ens18
    inet xx.xx.xx.112/24 brd xx.xx.xx.255 scope global eth0
      valid_lft forever preferred_lft forever

Ethernet on the host:

4: vmbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 3c:ec:ef:c7:dc:18 brd ff:ff:ff:ff:ff:ff
    inet xx.xx.xx.18/24 scope global vmbr0
      valid_lft forever preferred_lft forever
    inet6 fe80::3eec:efff:fec7:dc18/64 scope link
      valid_lft forever preferred_lft forever


Thanks everyone for the help.

Doing more research.  I can see the tap interface:


tap1001i0: flags=4419<UP,BROADCAST,RUNNING,PROMISC,MULTICAST>  mtu 1500
        ether 42:53:7e:6d:6c:3b  txqueuelen 1000  (Ethernet)
        RX packets 161  bytes 19570 (19.1 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 80022  bytes 4941978 (4.7 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

And this is the process on the host for that guest:

Okay, so update.

I installed a guest via Proxmox and it worked fine. But then I could compare the two guests and what I found is that for some reason Virtualizor didn't set a default gateway.  Adding the gateway manually into /etc/network/interfaces seems to have resolved my issue.

Still figuring out if this was user error or what.

Hi,


Have you added IPs in Ip pool before assigning to the VPS ?
Also have you enabled routed option in IP Pool ?
That will write extra route entry in network file.
