    (RRD Schema Changes in 2025) pve2/2.3-{type} vs pve-{type}-9.0 handling; ds & cf values; data migration?

    Hey, Looks like with the changes to RRD, there is a new data upgrade process, and some partially-reverted changes. Is someone able to please publish the ds/cf values for the below variants, that would be great. pve2-{type} vs pve2.3-{type} vs pve-{type}-9.0 It seems pve2-{type} no longer...

    PVE Guest Storage in RAID: SAS 24Gbps 15.36TB vs NVMe Gen5 E3.S 7.68TB vs Others?

    Hi all, Just looking for views of SAS vs NVMe for guest storage in current times, to get an idea of what makes the most sense with a potential system build: This is the compatibility matrix we've been sent about the options. SAS 24G @ 15.36TB per drive seems wise to me. From there, another...

    PVE API: Power/ACPI Actions (Start/Shutdown/Reboot/Stop) PVE Error/OK unclear, GUI vs API, etc.

    Hi there, Just comparing the attached realities of what is reflected for an OK action and then a not-OK action, there are a few things I'm curious about: Rather than just firing and hoping that if the request went through OK, that it is actually OK, we need to know the error/status. Comparing...

    Update from eg. pve-manager 8.0.4 to 8.0.9, not 8.1.3 (ie. retain PVE 8.0, not 8.1 yet)

    Hi there, Just checking the best way to "pin" a Proxmox VE version before running an upgrade, so as to update to the latest "dot" releases of the previous sub-major. Now that v8.1 is released, we'd like to get everything up to latest v8.0 minor/patch - is this easily doable? I'd imagine so via...

    VMs using "CPU Model" that matches the installed chips. Should we move to x86-64-v2-AES for performance?

    Hi, I'm curious about this - with the new update to the default CPU type when creating via GUI, and the note about performance efficiency, should we be changing over from using the most-closest-matching one from the list, instead to using x86-64-v2-AES to reap these rewards? Or are there...

    [SOLVED] PVE 7.4-x to 7.4-latest: grub failed to write to /dev/sda (then grub-install gives Disk Not Found) Debian bug 987008

    Hi there, Looking back at these posts and wondering what to do: https://forum.proxmox.com/threads/proxmox-update-from-7-2-4-grub-update-failure.114951/page-2 https://forum.proxmox.com/threads/problem-with-grub-upgrading-pve-6-4-15.115376/ The first being the most relevant. On just 1 machine...

    [SOLVED] pmg-smtp-filter: Many instances/children running, each at 50% CPU; 6-core machine exhausted after 30-90 minutes

    Hi there, Weird one, forked from this other thread about a similar issue. @Stoiko Ivanov pmg-smtp-filter after a while has many instances running, and with each taking about half a core, the machine is CPU-overloaded fairly quickly. We updated 7.x branch to latest (on same final sub-major)...

    [SOLVED] noVNC over API: PVEAuthCookie (PVE Ticket) and Tunnel Auth (VNC Ticket) - How? :-)

    Hi there, Just trying to get to the bottom of this after 2 days working on it. UPDATE: We were able to work through the niggles. Still I am getting 401 No Ticket despite there being a VNC Ticket from vncproxy passed into vncwebsocket by noVNC (via path), and a cookie set with PVE Ticket I...

    [SOLVED] LXC/QEMU via API - Parameter Verification Failed - Request params seem OK though?

    Hi there, We're troubleshooting a module which talks to Proxmox to provision VMs/CTs. In the pveproxy log we can see the request come in and get a 400 response for the actual creation attempt. Getting a ticket, etc, is OK (200). Trying to work out the 'why' there, we're trying to find more...

    [SOLVED] Cross-cluster Migration: Leaves VM on Old Host powered Off but still "Migrate Locked"

    Hi there, Just checking if this is expected behaviour. I know there is --delete which lets you remove it on-successful-completion however it details that if not used, it should stop. So with the job finishing successfully as below, it seems odd that they are still locked with the paper plane...

    (LIR IPv6 /32 into 2x Routers) Desire: /48-per-Type, Routing to /64-per-VM & /128-per-Domain?

    Hi there, This is a bit of an edge case, though being so short on time it's taking me a while to understand the inner workings of IPv6. There's a reason they say "throw out your understanding of v4 as it has no bearing with v6", holy moly are they right! It's great but needs to be understood...

    Feature request (Quarantine): Whitelist AND Send (in 1x click) option?

    Hi there, The filtering system we moved to PMG from had the option to Whitelist and Send in a single click when in the per-mailbox Quarantine web viewer. Would it be possible for Proxmox to consider adding this into the Quarantine web GUI? It would avoid quite a few 2nd requests to the web...

    Outbound IPv4: smtp_bind_address with a PMG cluster (standalone OK)

    Hi there, I replied on this thread, as we've been unable to find a way to "roll" the sending IPv4 address on our 2x PMG servers, but it hasn't seen any love yet. Should the servers have been standalone/single, it'd be easily done as we've verified. In a cluster, the system grabs the...

    1x NIC to 2x NICs (Keep VMs/WAN on 1st & Move PVE/Corosync/etc to 2nd)

    Hi there, I'm looking to update the networking setup for Proxmox VE now that the switches have been swapped out for more capable models. At the moment, each host has 1x NIC connected, which is serving VMs (WAN) and PVE (Web GUI, SSH, Corosync, etc). Static addressing for PVE is set against...

    Dual-NIC enablement with VLANs (VMs untagged) (Migrations/Backups/PVE tagged)

    G'day, We have 2x switches available, each with 4x 10G ports and 48x 1G ports. They're stackable, though we'd rather avoid it. At the moment, all hypervisors are routing through 1 of the 2 switches. They're going through the untagged handoff VLAN, with tagged VLANs atop. Those tagged VLANs...

    [SOLVED] Live migrations failing: Error 255 (for OVFTOOL/ESXi imported VMs)

    G'day there, With the help of the Proxmox community and @Dominic we were able to migrate our ESXi VMs across to PVE - thank you! https://forum.proxmox.com/threads/migrating-vms-from-esxi-to-pve-ovftool.80655 (for anybody interested) The migrated (ex-ESXi) VMs are now part of a 3-node PVE...

    [SOLVED] Migrating VMs from ESXi to PVE (ovftool)

    G'day from Australia, We've got a predicament that we'd appreciate some guidance with. 4x managed VMs run on 2x ESXi hosts (2+2), and there's no supported pathway to migrate them (ie. ditch ESXi in favour of PVE). Across the remainder of our infrastructure, ESXi has been gladly purged and our...
