@peter @homelab I've done it both ways. You can export the #vhdx directly from the #hyper_v host and then import it to #proxmox , convert it, and you're ready to go. You can also restore the #veeam backup to Proxmox. In both cases you need to make sure the networks and CPUs match up before you fire them up for the first time. The hardest part about the direct Hyper-V export method is you have to shut down the VM and finding a storage location that can be written to by HyperV and read by Proxmox.

Looking to migrate the #homelab from Hyper-V to #proxmox. The main VMs I care about are Ubuntu hosts running Docker containers.

I have an old Intel NUC I'm thinking I'll use. NIC doesn't support VLANs sadly but I think I can get away with untagging it to my server network and just use a bridge for now. Also have Veeam backups so might try and restore those directly to Proxmox.

Anyone else tried similar or have any tips?

@homelab

Well, it's been a little over half a year of running my daily driver #LinuxMint desktop virtualized on top of #Proxmox. It worked _remarkably_ well, with a couple of minor annoyances:

- having to use the proxmox web ui to manually pass through any USB device I was plugging in (required because I don't have enough PCIe slots to just use a dedicated USB card)
- sound would occasionally glitch out and require a reboot of the VM
- minor performance glitches every so often

All in all, it ran way better than such a janky setup should.

But.

The dealbreaker was when I started needing to edit audio and video, and more importantly, sync audio and video in #DaVinciResolve. Audio playback would lag there and in #Ardour by up to 500ms and no degree of compensation could make up for it.

Fortunately, since I had installed Mint to a physical nvme drive, switching from a VM to bare metal was as simple as booting from that NVMe.

I had installed Proxmox to a pair of 800GB enterprise SATA SSDs that have ungodly write endurance, so maybe I end up with 1.6TB of swap?

[ Blog ] Veeam #Worker on #Proxmox VE: "Cannot access a closed Stream" error

When you try to #deploy a Veeam Worker in a Proxmox VE environment, you might encounter the error "Cannot access a closed Stream".

This error prevents the Worker from deploying correctly and, consequently, stops you from backing up the Proxmox VE platform.

Pourquoi j'aime l'#opensource, nouvel épisode. Je viens de voir que l'on pouvait facilement installer #Yunohost sur #Proxmox via des scripts et LXC. https://community-scripts.github.io/ProxmoxVE/scripts?id=yunohost

Je sais lire un script, j'ai accès au code source, il est sous licence MIT. Je vais pouvoir l'adapter à mes besoins, améliorer, repartager.

Dès que j'ai un peu de temps perso, de nouvelles expérimentations en vue sur mon #homelab !

Hey #proxmox folx. Do I want/need a subscription? I am running fine without it but I was wondering if it was a good idea for some reason I'm not seeing.

@Khrys
bravo!
c'est le principale problème des serveurs en production... ha juste encore un petit... et paf
d'où l'idée avoir plusieurs serveurs et une possibilité de retour en arrière
perso j'utilise Proxmox comme superviseur
ça donne une couche de plus à se farcir
mais ensuite on peut vraiment faire n'importe quoi, des tests les plus fous, avoir plusieurs Yunohost en LXC, des copies , pouvoir remettre la machine d'avant etc et des sauvegardes faciles
#Yunohost #proxmox #autohebergement

My thought so far went that I definetly want #Proxmox installed on each node and use it's ceph integration.
Live migrating VMs would be nice, but is not a must-have. The services hosted on this setup will not be any critical.

@keisatsu @homelab

I've always made the static assignment at the DHCP server and not the node. That way there's a single source of truth for IP addresses. That relies on machines having a stable MAC, which you get on bare metal automatically but you have to play games to get that on VMs.

I was pleased to see that if you set a #proxmox VM to generate its MAC with the auto option during creation, it stays stable after the first bootup. It makes shuffling VMs and LXC containers around the cluster a lot less painful.

Das #Minilab ist erstmal fertig 😁. #Proxmox ist installiert und der #Cluster konfiguriert. Angebunden ist das Rack erstmal per WLAN. Mal schauen, ob ich das noch ändere. Die Alternative wäre, dort wo es aktuell steht, nur DLAN 🫣

ProxCLMC for Proxmox VE Clusters

It really is surprising sometimes how #homelab services grow....and I just want to emphasize that it's silly to think that you'll be the exception.

Prior to doing my big holiday cleanup of scattered docker containers being moved over to first class, fully automated #proxmox and #kubernetes being managed by #ansible and #argocd, I thought for sure I knew exactly how many services I would be running.

I also felt confident that I didn't need anything more than that.

Low and behold, the old adage holds true.

Tonight I was working on my deployment of #netbox (https://github.com/netbox-community/netbox) and I realized that it uses #Postgres under the hood.

No big deal. I've got a Postgres instance already running in the cluster.....except that I wrongly made the assumption that #paperless_ngx would be the only consumer, and I turned off the superuser.

Still no big deal....except that I'm deploying everything via GitOps as much as possible, AND I've already got live, important data in Postgres.

*long sigh*

So...now I get to go do some manual surgery on users and databases to make it be a proper cluster wide, multi-tenant service, I'll make the gitops side of it look pretty later.

And that's when I realized that keeping an instance of #pgadmin around would be super useful going forward.

I was, in no way, planning on running a PgAdmin instance, but here we are.

Well...guess what? I'm also running Mongo, InfluxDB, and Redis.

Thankfully, Influx ships with a WebUI...but if I'm already adding pgAdmin, then there's no sense skipping #Mongo Compass and #Redis Insight.

And that's officially 3 more unexpected services to deploy in a single night.

#proxmox #backup server

After settling into Proxmox VE to replace VMware I have just been checking this related service.

So far, impressed. Obviously tightly integrated with PROXMOX VE, which is a good thing.

Updated my Proxmox Hardening Guide -> it now includes Proxmox VE 9.x and Proxmox Backup Server 4.x guides (plus minor improvements to the existing PVE8/PBS3 docs).

Checklist style hardening controls with Proxmox specific guidance.

I’m especially looking for feedback and lab testing on any controls that are still marked not validated (see README ToDos).

Moved the workstation CPU/RAM/disk/GPU to the motherboard previously used for the #proxmox server. Now it’s in a (nice) case instead of a bench 😅

Manage to do all the changes without breaking #SecureBoot once 🙂

I was a bit scared because after the change I had some instabilities (lockups, failure to boot), turns out, I can’t use XMP with the RAM and motherboard combination 🤷‍♂️

Unfortunately, I can’t yet bring the proxmox machine back up, as the PSU does not fit in the (new) case I have for it 🤦‍♂️

#computing #weekend

After reading the case manual, turns out, my PSU can be (barely) installed in the new case.

So, the #proxmox server is back online 😊

#proxmox successfully installed on an old Chromebook. Waiting for a usb-c ethernet adapter to integrate it into a small cluster. i5-something + 8GB ram. emmc disk device was problematic but a simple workaround is available.

Plenty of power to run small containers.

Alas, https://forum.proxmox.com/threads/ceph-unable-to-find-a-keyring.141189/ states that the message is just cosmetic…

#Ceph #Proxmox

Root cause of the #Ceph issues seem to be an upgrade and reboot of one of the 3 #Proxmox nodes.

On that node systemctl status ceph-crash shows that it can't find the keyring:

Jan 04 18:37:06 baldur ceph-crash[3702657]: 2026-01-04T18:37:06.772+0100 7f35a3ca56c0 -1 monclient: keyring not found

On another node not upgraded, no issue.

Migrated my tax consultant from #esxi to #proxmox with offsite backup via #PoxmoxBackupServer ! Used a temporary Proxmox server to import ESXi-VMs, removed the LSI controller and reused the „old“ hardware! Now we are both happy, feel far more safe & secure and sleep better…

@Rutrapio thanks! Previously I ran #Proxmox (so proper VMs), but this time I opted for a lighter weight approach with pure docker compose setups for everything. The OS doesn't matter all that much then and #Debian is a stable and "pure" option.

O #writefreely é absolutamente leve.

O LXC da https://lacra.ia.br no #proxmox usa 68 megas de RAM e 200 KB da base de dados SQLite no armazenamento (40 Megas contando o software ele mesmo e 1.3Gb contando a imagem Debian completa que o hospeda).

Vai demorar pra encher os 8 GB alocados :-)

Claro por enquanto a #lacraia só tem 3 blogs (5 com os convites que mandei agora) e só um post então não deveria me surpreender. É que a gente tá tão acostumado a software usando absurdos fazendo nada que fico em choque quando algo e simplesmente normal.

hey #proxmox users! today I another new brew roll by for `pvetui` which is a text/terminal UI for managing a proxmox #hypervisor in a terminal window. it's pretty great for being able to quickly check on things and can use token or password auth.

I have two servers in two locations and am about to refresh hardware on them and will continue using proxmox most likely so i'm pretty happy i saw this tool.

#pvetui should be in other package systems as well.
