    MSWX VM refuses to boot or bootloops on cpu change

    There is one ms windows vm which behaves quite peculiar. Changing the CPU away from anything kvm64 (> host) results in an inability to boot. Even a reboot into safe mode use msconfig does not work as per usual. Despite having configured a windows10 .iso to boot from the 'press any key to boot...

    Issues with Networking on KVM Guest

    Hello, I'm facing some trouble post-installation with networking on KVM Guests. After spending around ~6 hours on setting up networking to work for containers, it appears that KVM Guests can't connect to the internet. With that said, not all guests don't connect, Windows 10 guests connect with...

    Ask for best practice allowing host CLI diagnose if only one GPU that is passed

    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...

    Proxmox 6.x consumes more memory than assigned using ZFS

    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...

    Do I NEED KVM support on the host machine?

    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...

    Redirecting the ProxMox kvm to a TightVNC server running on VM with GPU passthrough

    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?

    Server Has Sudden Increase in CPU Usage and Load

    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%...

    Any recommendations for very Intensive cpu and networking KVM?

    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...

    High swap usage,alot of free RAM

    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...

    [SOLVED] Is there a recommended way to restrict IP addresses to VMs?

    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.

    Install containers/KVM on formatted ext4 lvm from /dev/pve/data(thin) on an SSD or NAS drive(ironwolf or skyhawk)?

    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...

    [SOLVED] Storage "Max Backups" option doesn't have any affect

    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...

    Shrink / Reduce a volume with an LVM-XFS partition

    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...
