I have never been able to get PVE's SDN functionality working. I have followed many guides on the web and on YouTube. I'm on PVE 9.0.5. When I try to get it to work, the VMs on different hosts can not talk on that SND network I set up. Anyone aware of a tutorial for setting up SDN so multiple...

Trying to update my list of templates. Got the same result on PVE 8.4.1 and on 9.0.5 Log output of /var/log/pveam.log: 2025-08-21 10:25:18 start download http://download.proxmox.com/images/aplinfo-pve-9.dat.asc 2025-08-21 10:25:19 download finished: 200 OK 2025-08-21 10:25:19 start download...

When I try to perform a Refresh on the packages, I get the following messages. They are duplicated for some reason. Does it matter which *.list file I edit? I never touch these files BTW. Fetched 1095 kB in 1s (1135 kB/s) Reading package lists... W: Target Packages...

I have two clusters, each mounting the same TrueNAS SCALE over the same NFS share. Considering that the two clusters can each have the same VMID, won't this cause naming conflicts on the NAS? Should I be using two different shares pointing to two different datasets?

I have been trying to get this to work for about a year now with no success. I have a three PVE cluster with three nodes. all PVE 8.4.1. I have two VMs, on different nodes but the same cluster. I need to have the two VMs to communicate with each other using static IPs over a private network. I...

I create a lot of VMs that are mostly the same configuration. Templates to the rescue! I know this will be really elemental for some people, but in Proxmox you can create a VM, will all of the tweaks and settings you routinely use. For instance: UEFI boot instead of BIOS Memory amount # of CPU...

I have a three node PVE 8.3.4 cluster. PBS is running as a VM on one node. Up until last week, it was backing up the PBS VM successfully for many weeks in a row via snapshots. I can certainly understand while the backup would fail as it is trying to freeze the VM while it is being snapshotted...

Don't know if people have considered the use of Proxmox VE as a development environment. Let me explain how I am using it. I am called on to develop installation scripts for Linux VMs. Most of these scripts make changes to the OS or install packages. Here is my methodology: Install the OS...

I have always used NFS shares which seems to be the most common sharing protocol but today I decided to compare NFS with SMB shares. All of my use is to host VM QCOW2 files. The storage target is a UGREEN DXP4800 Plus running TrueNAS SCALE. It has a mirrored pair of spinning drives. I created a...

I have a three node cluster. I am struggling to understand SDN. (This is the right way to go, right?) I want to create a private network contained within my cluster. "Simple" is an isolated bridge that does not allow VMs on different nodes to talk to each other. Given my simple needs, is VLAN...

I have a three-node Proxmox cluster, all running 8.2.7. I would like to create two Linux VMs on different nodes in the same cluster and have them be able to talk to each other. I assume using the SDN functionality is the proper way to do this. I have created a zone with an ID of sdn100 I have...

Suppose I create a VM on CEPH storage (RAW) and I snapshot the VM, where is the snapshot stored? Is it even a separate file?

Are there are configuration options or performance tuning available for CEPH?

PBS 3.2-2 I am trying to set up email notifications. When I go to Notification Targets, and hit Test, I get the test email with a From address like myaddress@company.com. I then go to my PBS storage and set up my verify job and run it, I receive a warning email from the mail server saying it...

PBS 3.2-2 I am trying to setup PBS to send notification emails to an SMTP server that does not need authentication to local email addresses. Here is what I set up: First thing I noticed is that even though I made a change, the OK button is greyed out. If I add a comment, the OK button is...

As we discovered with the Storage Review of Hypervisors, the default host type incurs a performance penalty. I would like to suggest a better "default" setting. With a single node, any setting other than "host" is pointless. In a cluster of multiple nodes all with the same CPU type, any...

In the documentation (https://pve.proxmox.com/pve-docs/chapter-notifications.html#notification_matchers_field) for type, only vzdump is listed. Is there a list somewhere of these types? Or is that it? Thanks.

What do the first and second columns with numbers represent? Should they not be labeled? Just wondered.

I have old backups for VMs that I have since deleted. Can I just safely delete the folders under /mnt/datastore_name/VMID ? A lot of backups so command line is what I am trying to do.

I'm trying to create a script that will output the MAC and IP addresses from the VMs on this host. "qm guest cmd 1017 network-get-interfaces | jq ." will generate a valid JSON file. But when I try to address the element "hardware-address" all I get is errors like this: # qm guest cmd 1017...
