I am having a Problem with one Debian Guest VM (running Debian 12 Bookworm AMD64, currently running the Upgrade to Debian 13 Trixie AMD64). It's extremely sluggish, even to just run apt update. While compiling Kernel Modules (e.g. zfs via dkms) I can see that the CPU Usage never gets above 15%...

I can observe several Issues (NOT only related to Proxmox VE 9 / Debian Trixie) but rather also e.g. Kernel 6.8 or even Kernel 6.5 on multiple Xeon E3 v3 Systems based on Supermicro X10SLL-F / X10SLM-F Platforms. This is what it looks like immediately after the Bootloader is exited and the...

On one Linux Client, ip -6 neighbor lists the Proxmox VE Host(s) as Router, when they clearly are not: 2XXX:XXXX:XXXX:1::A:B dev eno1 lladdr 11:22:33:44:55:66 router REACHABLE Setting sysctl -w net.ipv6.conf.vmbr0.forwarding=0 on the Proxmox VE Host fixed that, but I wonder if that also caused...

It just occurred to me that the Reason why I'm getting such a MASSIVE overhead on my Backup Server (which has 2 x RAIDZ-2 x 6 Disks each) is because the Default ZVOL on Proxmox VE is (or probably "was" for a long Time, and many of my Virtual Disks are quite Old) 8k, which results in a Space...

I had many problems related to VERY HIGH iowait on my Proxmox VE Systems using Crucial MX500, which is a Consumer SSD (and one with very little DRAM, so once that fills up, Performance drops like a Rock). Now I got 2 x Intel DC S3610 1.6 TB SSDs which should be very good for VM Storage or also...

I recently found out (kinda lived under a Rock in that Regards :rolleyes:) that the NIC I was using (Mellanox ConnectX-2 and ConnectX-3) do NOT Support ASPM and therefore the CPU will never be able to achieve high Power Saving States (anithing above C2/C3 IIRC). Same goes for my preferred HBA...

I have A LOT of VMs running on Proxmox VE across several Servers. Most of the VMs run Debian GNU/Linux Bookworm. Overall the KVMs seems quite inefficient, especially in Terms of: - RAM Usage (a bit less on Xeon E3 v5/v6, since up to 64GB RAM can be used there) - Disk Space (each VM takes 16GB...

I am (re)debating this Issue, as I have done in the Past. My use Case, as a Homelab user, is that some/many Hosts are up only when needed (at specific Times, in order to reduce Power Consumption), and so the "normal" way with Quorum doesn't really work. I had a look at...

I am bit surprised (and I think it's only happening since a few Weeks/Months) by the Error but it seems to be working somehow. I use certbot in a Podman/Docker Container to generates ALL Certificates for my Infrastructure. No, I do NOT use the ACME "plugin" of Proxmox VE, since I have wildcard...

I am observing some very high (>40%, sometimes 80%) IO Delay on Proxmox VE 8.2.2 with pve-no-subscription Repository. Looking at some Posts over this Forum, this may be due to not using Enterprise-Grade SSD, although to be honest I don't necessarily "buy" this justification. I am using Crucial...

I really like the Proxmox VE Product. However I am getting at my wits end with regards to the Firewall Logging Capability. It might as well be Chinese :( . Some Traffic to/from the OPNSense VM works (e.g. from my Home pinging Proxmox Host AND OPNSense VM works correctly), same from Proxmox VE...

As peer the title, I have a host (running Podman/Docker Containers) that is periodically hitting 100% ZFS Pool Usage due to the Snapshots that keep getting created automatically on the Host. I enabled TRIM on the GUEST ZFS Pool (yes ... I'm running ZFS in the GUEST on top of a ZVOL that Proxmox...

I am a bit dumbfounded with 2 Debian VMs on 2 different Proxmox VE Hosts. The boot process seems stuck as in the screenshot above. No matter how many times I refresh the page, the NoVNC Console always displays this useless page and I cannot do anything. However ... I could ssh and perform...

I recently upgraded Proxmox VE from 7.x to 8.x alongside a Debian Bullseye -> Debian Bookworm Upgrade. On some systems however, it gets stuck at boot. The only thing I can see over Remote Management / IPMI is, using Kernel 6.5.11-7-pve: Any ideas on how to debug further ? Kernel...

I successfully managed to setup PCIe Bifurcation on my Supermicro X9DRi-LN4F+, since I am using a NVME Expander (ASUS Hyper M.2 X16 V2) for 2 x NVME drives in striped configuration (planning to destroy & recreate as mirror for safety reasons !). The NVME Expander is *not* passed through any...

For some weird reason my recently installed "new" NAS is randomly rebooting (approximatively 1-2 times each hour). System: - Supermicro X10SLL-F - Intel Xeon E3-1270 V3 - 4 x 8GB Unbuffered ECC DDR3 - 2 x Crucial MX100 256GB - 1 x IBM Exp ServeRAID M1015 (LSI 9220-8i) -> PCI-e pass-through to...

Hi, I wanted to share my bits with you concerning my home lab cluster made of: - Permanent on-state machines - Ad-hoc machines (in order to reduce power consumption) Of course, besides the "usual" problems of voting (solved by assigning a much higher number of votes to the permanently-on...

I recently started playing with Proxmox VE 5.1.3 and so far my impressions are good. Due to some performance overhead of KVM for a distcc compile server, I tried LXC and I get bare metal performance essentially. The only problem is that, in order to avoid filling the local disk, I want to...
