i am using pve-manager 6.1-8, proxmox-ve 6.1-2, qemu-server 6.1-7, pve-qemu-kvm 4.1.1-4 whenever i try and take a back up when the machine is running i get the following: task error: vm * qmp command 'savevm-start' failed - the command savevm-start has not been found and indeed when checking out...

Hi all, I had some issue to connect to my proxmox sever which does not have IPMI (or iKVM). It is build on a Threadripper workstation with MSI TRX40 motherboard. I fixed the issue, which is not related to the proxmox. That lead me thinking: Since my only GPU has been passthrough, the frame...

After being faced a few times with extraordinary memory consumption i took a look at the shell using glances. out of principle i never count on swap space and don't configure it since my use cases don't call for it. While the RAM assigned is correctly estimated proxmox/kvm decided to consume...

I'm new to all this so please assume I know nothing. The objective is to install "Home Assistant" in a VM under Proxmox. There are various images available, VMDK, VHDX, VDI, QCOW2, OVA but I had no idea which one was best suited so chose QCOW2. I created the VM following various tutorials but...

Hello, in my cluster i have finded a vm with replication faild with this log: -------------------------------------------------------------------------------- 2020-11-02 12:54:01 105-0: start replication job 2020-11-02 12:54:01 105-0: guest => VM 105, running => 15447 2020-11-02 12:54:01 105-0...

Hi guys, I have a VM that has an RTX5000 passed though to it. I understand that when you passthrough a GPU to a VM the integrated ProxMox KVM no longer works. But I was wondering If I could work around this limitation, by telling ProxMox to connect to a TightVNC server running on the VM...

`qm template`: what does it _do_? what makes a template different from a (k)vm? Details I see references to how running `qm template [vm_number]` creates a template that makes future (linked or full) cloning better, more-efficient. But... what does `qm template` do to the (k)vm? (A bit of...

Hello, I'm experiencing a strange CPU usage/load issue: After starting (/restarting) my server, it has a CPU usage and load, which I would consider normal (CPU usage is around 6% and load around 1). Then after a few days (6 or so), all of a sudden the CPU usage and load increase to about 40-50%...

Hi i am going to deploy proxysql in my Proxmox cluster, it will be done using KVM and not lxc in order to be able to use VRRP to get H/A between several VMS in different nodes of the cluster. Is there any recommendation to the VM hardware setup, the Proxmox node itself or the VM configuration...

I'm seeking suggestions for debugging the following. After running a "clone from snapshot" in the web gui rev 6.2-11, I receiving the following output: TASK ERROR: clone failed: activate_volume 'pve/snap_vm-199-cloudinit_baseline_1' error: Failed to find logical volume...

Hi all! I've got a HP DL380 G8 running with 2x300GB 15k SAS in RAID 1 and 4x300GB 15k SAS in RAID10. Controller has 1GB of cache, Write Cache is enabled, BBU is present. Controller status is ok. I've just set it up (yes, raid resync is long done) and moved my VMs from my other server. LXC...

Hey, I've been using Proxmox for a while now, and I'm very happy with it. The only major issue I could not solve so far with the manual is the swap usage. I'm using an NFS share for storage, and the KVM processes seem to use quite a bunch of swap, even trough there is plenty of RAM to use...

How do you restrict (KVM) VMs to only use their assigned IPv4 and IPv6 addresses? I'm looking for something like filtering IPs by MAC addresses (for ex. via ebtables). Is there support for something like that built into Proxmox? What is the recommend way? I can't be the only one who would need that.

I have done this twice with a WD green and purple(both died, green was not suited for 24/7 anyways and purple was 2nd hand and I got cheap). Now I've got an SSD, where it initializes /dev/pve/data to make use of a big chunk of the SSD's capacity, so I what I usually do is make use of it via...

I run nightly KVM backups to an offsite NFS share that I have configured directly as a Proxmox storage, but I unfortunately only have space for a limited number of backups, so naturally I have the storage "Max Backups" option set to 3. Checked back a few (5) days later to find the storage almost...

I need to shrink a Proxmox-KVM raw volume with LVM and XFS. Now, XFS doesn't support shrinking as such. It's possible to hack around this with xfsdump and xfsrestore, but this would require 250G data to be copied offline, and that's more downtime than I like. Whats the alternative? I was...

Hello, It seems the ram usage in the webui is incorrectly reported in our case. The VM is an ubuntu 20.04. The host is running ZFS. Ballooning is off. This is happening for all of our VMs. Here's a picture of the webui: and here is free inside the VM total used...

We are looking to enable hotplug for the CPU for KVM guests. I've seen that it's only possible with vCPU and not Sockets nor Cores. Assuming the host has 32 cores, would it be best practice to set Sockets: 2 Cores: 16 and set the vCPU to 6 or according to the guest CPU need. If I understand...

Hallo, ich bin Neuling mit Proxmox und Virtualisierung mit Servern. Mit Linux kenne ich mich aber schon seit mehr als 6 Jahren aus. Zu Hause möchte ich einen neuen Heimserver einrichten. Vorwiegend sollen darauf Proxmox, Open Media Vault und Nextcloud laufen. Open Media Vault, so habe ich...

Hello, I used to run KVM VM with some licensed software in it (there is Debian and the software run in it). When the VM was setup the CPU was set to kvm64 and never changed. The software itself used to bind its license to hardware list of the PC (that is, VM), and the problem is, if I somehow...
