I'm looking for a solution to drop the need for intermediate bridges for a corner/edge case where I need the VMs to have "direct" P2P links ONLY, and typically to the host too. Reason: I want to use OpenFabric as a IGP, and it requires P2P links only , ie, only 2 parties to a link. As I add...

Hello, To have a rate-limit on the bandwidth of a VPS limited to 1 Gigabit/second, is it correct to set the rate limit to 125? Thanks!

It looks like QEMU agent is displaying disk usage instead of memory for some reason. Every time I install a package it just increases along with disk usage. Anyone every seen anything like this or know how to fix it? As you can see I am only using 4-500MB of memory but disk usage is lining up...

There is a new QEMU 9.2 available in the pvetest and pve-no-subscription repository. After internally testing QEMU 9.1 for a couple of months, and then 9.2 for a couple of weeks, we decided to skip a separate 9.1 update and move directly to QEMU 9.2 as the default version included in the next...

Hi! I have a main proxmox node with 5-10 VMs. I also have a remote proxmox node with PBS installed as a VM. I want to create some kind of disaster recovery site with this remote proxmox node. My plan is to take backup of the VMs every minute and send to PBS. Most of the VMs are static so...

I have virtio ballooning enabled in a few Windows Hosts that have allocated significant amounts of memory (64-128GB), however, most of that memory is not needed 99% of the running time, only for one off weekly tasks. I would like to reclaim that memory, but it seems that the way that Proxmox...

Hello everyone, I'm having a tough time with my home network configuration and could use some help troubleshooting a high-latency issue. I'm experiencing significant latency on my Intel i226-v PCIe NIC when passing it through to an OPNsense VM on Proxmox. Here’s my setup and what I've tried so...

Running a VM via the shell (to institute additional command line parameters) results in the syslog being flooded with qmeventd events like the following: qmeventd[1038]: error parsing vmid for 3371241: no matching qemu.slice cgroup entry qmeventd[1038]: could not get vmid from pid 3371241...

Hi, I have been reading about vhost-user and specifically vhost-user-gpu, which is used alongside VirGL/Venus on QEMU to provide "pieces"/"slices" of a GPU from the host to Guests/VMs. The problem with this is that using `dpdk`, this is running in user-space instead of kernel space, which is a...

With more modern hardware, core 2 core latency can become an issue. Check this software if you want to measure your CPU. https://github.com/nviennot/core-to-core-latency This is an issue, as just running on the "wrong" core combination, will slow down your software. This will become...

There's a new QEMU 9.0 available on the no-subscription repository. Internal testing for that version started with the release candidates over two months ago, and our engineers could contribute several complex fixes to the stable release. Today our QEMU 9.0 package has been made available on the...

Hello everyone. I just had a few question about Risc-V emulation on proxmox using qemu. The package qemu-system-misc provides the binary /usr/bin/qemu-system-riscv64 that allows for emulation of riscv64 if i'm not mistaken. Problem is apparently this package isn't the one used by proxmox, there...

I installed macOS in a VM on Proxmox 8.2.2, and I want to use copy/paste between my main computer and the VM. Is there a QEMU guest agent for macOS available?

I recently saw this commit https://git.proxmox.com/?p=pve-qemu.git;a=commit;h=2cd560e0d2d700159d3dbf452815b006996765ae and read the 9.0.0 announcement last month. Anyone knows when qemu v9 might land in a public PVE release?

When installing the guest agent on some servers we are encountering this error when attempting to install the Guest Agent. "Service 'QEMU Guest Agent' (QEMU-GA) failed to start. Verify that you have sufficient privelleges to start system services." This kills the installer and it rolls back...

Hello, I have a HPE LTO tape reader+changer connected via a SAS card that I want to use from inside a qemu VM on proxmox. After a bit of reading, I have been able to connect it like follows (I put here the full process, in case other people are interested) : On the pve, I find out which are the...

Link To Solution Hey, I've recently started to experience failure in all of my backups. Shortly after I've realized that this has nothing to do with my backup servers because other people can still backup to them, so it's clearly something at my end. I've narrowed this down to an issue with...
