network configuration

I am using cloud-init to set up some Ubuntu 18.04 VM's (uses netplan for net config) They are all configured using static IPv4 address like 192.168.0.x/24 The gateway is 192.168.0.254 The generated /etc/netplan/50-cloud-init.yaml file does not contain gateway4 attribute

Hi, We're testing proxmox 5.2 running the latest enterprise version. We have a few LXC containers running on the hosts and managed through HA. When we reboot a host, all of the containers are started, but their network connections do not work. The only way to re-establish network connection to...

Hi everyone Since the startup of the server, there is a problem with network server failure. Network server is disconnected and re-connected every so often. message log: Jul 11 06:40:15 isvps085 kernel: [60086.694591] vmbr0: port 1(enp0s31f6) entered blocking state Jul 11 06:40:15 isvps085...

Hi, I have a cluster with 6 nodes (HP Proliant 385 G6) with 4 NICs/host. My plan is use those NICs network subnets as: NIC1 vmbr0: network for kvm and lxc guests (192.168.3.0/24) Gateway 192.168.3.254 NIC2 and NIC4 bond0: network for manage and storage traffic (192.168.2.0/24) Gateway...

I have a container which needs two interfaces and certain features, like this auto lo eth0 eth1 iface lo inet loopback allow-hotplug eth0 eth1 iface eth0 inet static address 192.168.11.38 netmask 255.255.255.0 gateway 192.168.88.1 mtu 1458 post-up ip route...

Does anybody have recent experience (Virtual Environment 5.2-2) with using proxmox on scaleway baremetal? Seriously frustrated! Several issues that all seem to be network related: 1. Allocating vmbr0 to the eth0 nic stops the machine from booting up 2. Cant ping 8.8.8.8 3. CT's are not...

Hi there, I am using Proxmox VE 5.1 in a datacenter. My current setting is that all VMs share the same public IP address. I have also available second public IP address that I would like to assign / dedicate to one VM. The configuration I have is that the PVE has the following...

I have two different segments of IP addresses, 23.10.6.218/29 23.10.8.1/24 gateway 23.10.6.217 The server network configuration is as follows: auto lo iface lo inet loopback iface enp1s0f0 inet manual auto vmbr0 iface vmbr0 inet static address 23.10.6.218 netmask 255.255.255.248...

I had to reinstall Proxmox and on the new install I cannot get any VMs or containers on the network. This is true for both new guests and guests that I've restored from backup. They can ping the host, but no guest can ping anything else and no guest is reachable from other hosts. Here is my...

Good morning everyone, i just configured my back interfaces (10GbE) of my three new servers. To provide enought redundancy and availability i connected my three servers the following way: Hardware Config: - Every Node has 2 10GbE SFP+ Ports that should be used only for Cluster communication...

Hi, To share a folder between virtual machines I have some questions: 1. How should I share folders between virtual machines? Install NFS-server on Proxmox main host? Install NFS-server on a LXC container? Install NFS-server on a KVM based machine Mount a folder with Bind Mount to a LXC...

I'm trying to add an IPv6 subnet to my proxmox host for use on my VMs. I have the following: interfaces file: auto lo iface lo inet loopback iface lo inet6 loopback iface enp7s0f0 inet manual iface enp7s0f0 inet6 manual auto vmbr0 iface vmbr0 inet static address 22.144.64.130 netmask...

Hi, Do you have a solution for remote access to virtual machines with only one public address for proxmox server and machines connected with NAT configuration? Regards Thank you

Hello, I am completely new to Proxmox and have set it up on a Supermicro X9 motherboard with dual Xeon processors. I am using the Supermicro onboard intel gigabit LAN to connect the server to my router. I have something strange going on, when I start the server I can connect to Proxmox through...

Hallo, sorry, I could find a how two or a post on this. Probably because i don't know how to describe it in a proper way. How do I implement a "virtual" network that should just work between tree VM. Like a local network. The VM's has no connection to the physical nic. The setup should look...

Hi, Ubuntu 17.10 network configuration is completely changed. This new tool replaces the static interfaces (/etc/network/interfaces) file that had previously been used to configure Ubuntu network interfaces. Now you must use /etc/netplan/*.yaml to configure Ubuntu interfaces. I downloaded this...

Hi, I have a proxmox which have 4 VMs. I defined 3 vmbr(0,2,3). vmbr0 is connected to the Internet and vmbr2 and vmbr3 are connected to two separate physical interfaces. Each VM has 3 interfaces which are connected to the virtual bridges. I have latency in VMs when I ping other VMs and two...

Hi, I'm a new user of proxmox (I use it since ~3 weeks). I only have a node with Proxmox VE 5.1-41 on a SoYouStart's (OVH company) dedicated server. I want to run Windows 10 1703 on a VM but each time I tried, I got an "Unidentified Network" on my VM. Here is my configuration : I added virtio...

I created a bridge (vmbr3) yesterday and rebooted my proxmox hypervisor but vmbr3 is not coming up at boot and the VM using this bridge is failing to start automatically. I can `ifup vmbr3` and start the VM by hand, but I'd like to know what's not working correctly. My /etc/network/interfaces...

Hi, first, I am new to Proxmox and hassle with the networking stuff. I know, this - or similiar problems - are discussed all over the net but I checked out a lot of tutorials and forum posts like debianforum.de/forum/viewtopic.php?f=30&t=149440 or...
