Beginning with ZFS 2.4.0 special devices (https://github.com/openzfs/zfs/pull/17505 ) will use a special device also for the ZIL, thus you won't need a dedicated SLOG device then (but can still add it if you consider it useful for your usecase)...

SteveITS replied to the thread Windows Server 2025 CPU suddenly at 100%.@kfietz In fact file /etc/modprobe.d/kvm-intel.conf exists on that node containing "options kvm-intel nested=N" which does exactly that. I will have to go back and look as to why that was added. Thank you for getting me there. At least I was... -
Wwhatthefiswrongwithcluste replied to the thread Server 2025 High CPU.Yes, this is specifically with Server 2025. I have not encountered this with other operating systems. My CPU usage is also not 100% but rather constantly around 8% to 11% despite the VM being idle. qm config: agent: 1 bios: ovmf boot...

MMarc_de replied to the thread [SOLVED] cores vs CPUs.Thank you for the swift reply @leesteken , that solved my question. I would mark this thread solved, but I do not know how :oops: (I just signed up).

MThe Linux kernel calls them CPUs (and that is what Proxmox shows in the node summary) but they are actually hardware execution units (historically called CPUs), which corresponds with (hardware) threads nowadays. Proxmox calls them (virtual)...

Vverishare reacted to DamienDye's post in the thread Optimizing Windows VM performance on older hardware - settings advice needed with Like.
Have you done owt inside the guest to tune Windows for running in a VM? Things like disabling the visual effects, killing hibernation and Fast Boot, setting the power plan to High Performance, deferring TRIM, and stripping out the background I/O...

Vverishare reacted to IsThisThingOn's post in the thread Optimizing Windows VM performance on older hardware - settings advice needed with Like.
1. v2-AES is perfect 2. Do you use ext4 or ZFS? What performance are you looking for? Reas? Write? Small files? Big files? A DB? Something with syn or asyc writes? 3. I mean, if it works, why not. On the other hand, do you make any use inside the...

Vverishare replied to the thread Optimizing Windows VM performance on older hardware - settings advice needed.Thanks for clarification. I thought the "Host" type was the most appropriate option. Thanks for pointing that out and correcting me. I'm using ext4. This VM is mainly for running and testing software like Mystnodes, Honeygain, P2P VPN apps and...

Ddrpepper285 replied to the thread IOMMU/DMAR Regression (PTE Write access) on Alder Lake-P (Ugreen DXP6800 Pro) – 6.17.13-2-pve vs 6.17.9-1-pve.Great to hear, another one where disabling super pages helped. I have scanned the forums here for similar IOMMU issues and I believe at least few of them are all related to the same issue of super pages. Took me a lot of digging around and my...

Hi everyone, First of all, sorry for disappearing for so long. To be honest, I assumed I would automatically be subscribed to the thread after creating it. It even shows that I am watching it, but for some reason I never received any...

MHi forum I noticed that the node summary page and the assignment of processors page do use different terminology. In the node summary under CPU usage a # of CPUs is stated, whereas in the Edit: Processors section a field called Cores is present...

JJohannes S reacted to robertlukan's post in the thread Best practice: Upgrade from PVE 8 to 9 with Ceph with Like.
A very small advice, before rebooting a Ceph node, stop OSDs manually, more info here(why): https://bugzilla.proxmox.com/show_bug.cgi?id=7827 https://forum.proxmox.com/threads/vm-processes-stall-when-rebooting-adjacent-node.185178/#post-862294

No that will take forever. :) And require enough storage. With only 2/3 nodes up Ceph should still function if its storage is not unbalanced. The VMs should stay running. They just need to move off the node being restarted. Which can also be...

VictorSTS replied to the thread Nested PVE (on PVE host) Kernel panic Host injected async #PF in kernel mode.In my case, it works correctly as soon as disk swap is disabled in the host (i.e. works fine with zram or with no swap, haven't tested zswap yet). -
