  2. vmbr0 is working but not vmbr1 (OpenVZ vs KVM)

    Hi there, I have a problem with my configuration. Basically the vmbr0 has OpenVZ containers which are working as intended.

  5. [SOLVED] Isolate Containers from One Another

    So here is the setup I have. A single, public, proxmox server running version 4.1-22. It has a single NIC with a single public IP. And that is all I can get. So naturally I am using NAT behind that public IP for my containers. So on the physical host, Eth0 --> Vmbr0 /w public IP. In...
  6. [SOLVED] Brocade 1020 on PX4.1 host + VirtIO net on guest == TX Checksum Badness

    Howdy all, I recently upgraded my Proxmox 3.4 install to 4.1 and since the upgrade, I can't use the VirtIO network driver on Linux clients. (We don't run Windows, so I can't test.) The setup is fairly basic, a Quanta LB4M switch with 2x 10G SFP+ ports, two servers each with a Brocade 1020 CNA...
  7. What's the proper way to specify a multicast address in 4.1?

    Hi, TL;DR: What's the correct way to specify a multicast address in v4.1 in a way that proxmox is aware of it and won't overwrite it in the future? Longer version: Just installing 4.1. My network admin has specified a multicast address which I must use. In a one-node config, I figured out...
  8. Bridged Network Adapter Does Not Connect Outside Server Environment

    I have a Proxmox VM that is setup with a bridged node network adapter, but it's not able to receive a DHCP IP from the DHCP which is on the same subnet as the Proxmox host. If I assign a manual IP to the VM in the subnet the Proxmox host is in, it can ping the Proxmox host but nothing outside of...

  10. Connection Refused by ProxMox

    I have had an issue ever since I installed ProxMox, whereby it will refuse all connections from a specific IP address and I cannot work out why it is happening. If I restart the server and connect to ProxMox via the WebUI or SSH it will allow the connection. If I go back to it later and try to...
  11. IP Address Passthrough to pfSense KVM

    Hi, Long ago, I had set up PVE to pass the external IP address through to a KVM firewall by doing something like the following: PVE's vmbr1 was on eth1 with a static address of 0.0.0.0. vmbr1 was eth0 on the KVM running the firewall distro. The firewall distro had its eth0 set to the external...
  12. How To Connect To KVMs With Just 1 Public IP Address (Kimsufi VPS)

    Hi, I have PVE4 installed on a Kimsufi VPS, & I have just the one IP address on vmbr0 with which to access the host. As such, I have my KVM set with NAT selected in the network interface, since there aren't any more addresses that can be assigned to it if I were to use a bridge. How do I need...
  13. [SOLVED] Unable to Add IP to VM

    I am having problems configuring the first VM's networking after a fresh bare metal install of Proxmox. I have tested the IP I'm trying to add by adding it as an alias to the HN's interface and it works fine. I then remove it. Then I try to add it to a Centos7 VM using ifcfg-ens18 and...
  14. /etc/network/interfaces

    Will someone explain to me the dummy0 interface and how it is created? I have an OVH dedicated Proxmox server and the default installation has a dummy0 bridged on vmbr1. Where does it come from what is the purpose and how is it enabled? I want to create an internal network bouncing off of the...
  15. Change PXE ROM

    Is it possible to replace iPXE with PXELinux (or something that works like usual hardware PXE)? I already have PXE server that works perfectly and I don't want to change its configuration. But also I want to boot my VMs as physical machines. Google for an hour but with no luck.
