Hi, After maintenance a couple days ago, one of the Windows VM on our cluster has decided to stop completing back-ups. Whilst the back-up job is running, the qemu-guest-agent for Windows seems to crash, which also results in the console not functioning and displaying an vnc proxy error. This...

Hi, We're in the process of installing a new node with the latest PVE ISO file (proxmox-ve_8.1-2.iso), however it doesn't seem start the installation. Instead it throws up a couple errors. Currently it is giving us the following error: -> "mounting /dev/loop0 on /mnt/.base failed: Invalid...

Hi, Yesterday we started an upgrade of a cluster that was installed in 2017 and has been upgraded since. We were going to upgrade Ceph from Pacific to Quincy, and commenced by redeploying the mons, because the mons were still using leveldb, which is no longer supported in Quincy...

One of our clusters used to have HA enabled, whilst not anymore it seems one of our pve-nodes had been rebooted by watchdog-mux. Looking at the logs, the machine rebooted at 15:31:10, not even 4 seconds earlier this message is displayed: Jan 06 15:31:06 watchdog-mux[2482]: client watchdog...

When we try to backup a VM we get the following error: 364: 2023-08-31 01:34:08 INFO: Starting Backup of VM 364 (qemu) 364: 2023-08-31 01:34:08 INFO: status = running 364: 2023-08-31 01:34:08 INFO: VM Name: CORP-DC 364: 2023-08-31 01:34:08 INFO: include disk 'scsi0' 'Ceph:vm-364-disk-1' 800G...

We are organising a Proxmox VE day in the Netherlands, Ede on Thursday on the 12th of October 2023. In the morning, we will discuss how you can innovatively meet your virtualisation, storage and private cloud needs within your budget with Proxmox VE. We will also look at how to easily achieve...

Hi, Last friday we encountered something 'funny'. We installed a VM on the hypervisor earlier that week and everything was fine. Friday, we noticed that the VM thought that the time in the VM was somewhere 16 December 2217. First I thought of a weird NTP daemon somewhere, combined with...

Hi, while managing a lot of clusters, we often run into the issue that customers have thought about where they want to have their VMs running. So, when doing maintenance on a cluster, after a reboot of a node, we need to place the VMs back on the node that they were running on. Also, when you...

Not sure if this should be in PVE or PBS, but I installed a new Windows server with all bells and whistles, and I am unable to backup the guest: INFO: starting new backup job: vzdump 146 --remove 0 --notes-template '{{guestname}}' --node proxmox2-6 --mode snapshot --storage pbs_extra INFO...

Hi, I have a user that is restricted to a pool. The user wants to restore a backup, but is not able to select a pool where the vm needs to be created in. How can the user restore into a pool? I can only think if 'create a dummy vm in a pool, and overwrite it', but I think the vmid needs to be...

Hi, a customer of us has a VM with 9 snapshots that are not visible in the webgui. Normally you see a line with the name "NOW" and description "You are here!" but that is also not showing for this VM. For other VMs the snapshot function works as expected. Both on ceph and through pvesh the...

Hi, I thought it would be nice to give you guys an update on our PBS setups, so I've written a blogpost about it. If you have any questions, let me know. https://www.tuxis.nl/proxmox-backup-server-rocks/

Hi, We're working on a portal for our customers so they can order VM's (and other stuff) without having to login to our Proxmox GUI. All works well thanks to the API, but now we want to be able to show the user the console. The API documentation tells us that we should do a POST on vncproxy...

Hi, we're working on something cool and are using the metric server service from Proxmox. While checking the values for IOPS, we see a different amount of IOPS in InfluxDB than we do via SNMP (in LibreNMS). The influx iops reported by Qemu, are those the IOPS issues by the GuestOS to the VM...

Hi, We run quite a lot of clusters on which we configure a AD-Realm that users our AD-setup to authenticate our personnel. We also use 2FA (OTP) for our realm. I add users with command: pvesh create /access/users --userid "{{ item.userid }}"@TuxisIE --groups Administrators --firstname "{{...

If I create an API token and try to use that token to make a new backup, I get the error: ERROR: VM 785017 qmp command 'backup' failed - backup connect failed: command error: backup owner check failed ($USER@pbs!CD != $USER@pbs) I would expect an API instance of a user to be the same 'owner'...

Hi, saw a thread last week speculating about the required size for a 'special' device in a PBS ZFS Pool. We now have about 8TB of active backups in the pool, and every time I calculated the special-device size for this pool, it was about 0.5%. So, to calculate the max size of your...

Hi, When trying to run a PBS backup on a VM that is running for some time, you get the following message: PBS backups are not supported by the running QEMU version. Please make sure you've installed the latest version and the VM has been restarted. We can run backups on VM's that we migrated...

Hi, Are there any (python) API Clients available? I want to gather some data through the API, but cannot find clear documentation on how to use the API. Am I looking in the wrong place?
