I have a Proxmox cluster (5 host nodes) where each host nodes uses vmbr0 for network access (contents of /etc/network/interfaces includes): auto vmbr0 iface vmbr0 inet static address 10.XXX.XXX.XXX/24 gateway 10.XXX.XX.X bridge-ports eno1 bridge-stp off...

I am trying to install ifupdown2 on my proxmox hosts but when I try to do it with apt I get the follow: # apt install ifupdown2 Reading package lists... Done Building dependency tree Reading state information... Done The following additional packages will be installed...

I have set up a cluster with VMs on different host nodes: h1, h2, h3, h4 I have used a OpenVswitch bridge (vmbr2) defined on h1: auto vmbr2 iface vmbr2 inet manual ovs_type OVSBridge post-up ovs-vsctl add-port vmbr2 gre1 -- set interface gre1 type=gre options:remote_ip=''ip...

I have a VM with a 42 GB hard disk (format raw, zfs file system) which I'd like to reduce to 32 GB. I thought I could use parted to reduce the partition on the VM first and then decrease the PVE size but I'm struggling to find a method to do this? Is there any method / documentation available?

I am testing some file transfer speeds in PVE 6.2-4. I have got two VMs on a host both using same bridge (with no ports/slave) for private network (192.168.1.X). They are both using VIRTIO network device, a zfs pool for harddisk space and have 3GB or RAM and 1 socket, 2 Core CPU. The file...

I have configured a 5 node PVE cluster with VMs accessible via NAT. I created ZFS storage on each PVE node (using some of the hdisks) for VM disks. I then set up VM replication from node 1 to 2, 2 to 3 ... 5 to 1 every 10 mins and using HA could get VMs to migrate and (re-)start automatically...

I have created some VMs and VM templates on a PVE node for testing. The node has a SSD and 4 SAS drives. I installed PVE on the SSD drive and assumed when i selected local-lvm as the VM disks the VMs would all use the SSD for storage too. When I look under Node > Disks now I see that the usage...

I am looking at the option of configuring a PVE cluster with storage replication (using a ZFS pool across the cluster nodes) so VMs and CTs can be moved to another node if the original host node has a failure. This is probably a PVE independent question but: when I create the initial ZFS...

I had been trying to create a private IP (NAT) setup for my VMs and managed to do it as follows, heavily relying on infomation in reference [1]. I have re-titled this as a Tutorial now: 1. In the Proxmox web interface for the host network configuration create a second bridge: vmbr1 with IP...

I'm exploring methods to provide redundancy/failover for VMs running on a PVE cluster. I am wondering if, using the Proxmox Replication functionality I can: 1. replicate a VM on Node1 to another node (say Node2) in the cluster at a certain time point T, 2. automatically or manually start the...

I have got 5 nodes with 2 physical NICs connected on each. I have assigned each node (management) a public IP address on my network (10.140.79.X) using the default Proxmox setup and created a Cluster. I plan to create a second bridge for private network for VMs. I also want to install CEPH to...

I am new to Proxmox and wondering how best to configure a network on a cluster so that the VMs are acccessed via the physcal (host) node IP addresses. i.e. I don't want to take up lots of IP addresses on my network so ideally there will be a bunch of VMs on a private network and they can only be...

I have tested out Proxmox (most recent release) using nested virtualization and now want to test it on a physical node: a Dell R630 server which has a SATA and 2 SAS drives installed. I create a bootable iso on a USB drive (DD mode) and booted to this and then selected the option to install but...

I connect to the internet through a proxy which (I don't have control of) and I've tried setting through the Proxmox web interface: "Datacenter" > "Options" the correct proxy as I have used elsewhere i.e. with format http://<username>:<password>@<proxy_ip_address>:3128/ but when I try to...

My management node was configured with FQDN/static IP and all other network settings correct and have tried to access the web interface but cannot access from two other (tried so far) Windows 10 systems on same network (using either Firefox / Chrome / Internet Explorer and Edge). Using 'curl'...
