Hello All, Here's another technote in the Windows on Proxmox series. In Part 4, we quantify and compare IOPS, bandwidth, and latency across all storage controllers and AIO modes under ideal conditions (i.e., "unloaded"), utilizing Windows 2022 running on Proxmox with iSCSI shared block storage...

Greetings everyone, Good news! We've managed to carve out some time to compile the latest data set for our ongoing exploration of Windows 2022 server on Proxmox. Part 3: Computational Efficiency of Storage Controller Configurations under Constrained Bandwidth Workloads Expanding upon the...

Hey everyone, Given the recent developments with VMware/Broadcom, we've noticed a surge in inquiries related to running Windows on Proxmox. To assist those transitioning away from VMware, we've thoroughly examined Windows Server 2022 storage controller compatibility, native driver support...

Hello Everyone, This is a quick note to inform folks that our Proxmox storage regression test suites picked up an issue with PVE8 on Debian 12. The regressions are generally applicable to multi-path storage configurations. Our initial analysis suggests that the issue is specific to Debian 12...

Hello Everyone. We received excellent feedback from the previous storage performance investigations, particularly the technotes on optimal disk configuration settings (i.e., aio native, io_uring, and iothreads) and the deep dive into optimizing guest storage latency. Several community members...

Several customers have asked us how to get the best possible storage latency out of Proxmox and QEMU (without sacrificing consistency or durability). Typically, the goal is to maximize database performance and improve benchmark results when moving from VMware to Proxmox. In these cases...

Many discussions have compared Proxmox and VMware from a feature perspective, but almost none compare performance. We tested PVE 7.2 (kernel=5.15.53-1-pve) and VMware ESXi 7.0 (update 3c) with a 32 VM workload to see which performs better under load with storage-heavy applications. The results...

Hey everyone, a common question in the forum and to us is which settings are best for storage performance. We took a comprehensive look at performance on PVE 7.2 (kernel=5.15.53-1-pve) with aio=native, aio=io_uring, and iothreads over several weeks of benchmarking on an AMD EPYC system with 100G...

Before opening an FR, I wanted to check here to see if I may have missed something: While integrating our CI I noticed that on restore of a VM to a new VM ID the MAC and SMBIOS stay the same (arguably as expected). However, unlike vzdump, qmrestore does not appear to have a "--script" option...

I'm sharing this with the group in case anyone else wants to build a CI environment for Proxmox testing. It makes for a decent Proxmox health check as well. To reduce cycle time, we needed a small footprint Cloud image for our internal testing and development. Cirros is a well-known image used...

Is there a "qm rescan" equivalent API/pvesh call? thank you
