    LXC load averages are wrong in Zabbix on PVE 8.x in LXC containers

    After upgrading to PVE 8 and several CTs to Debian 12, I experience a loadavg discrepancy. The load averages shown in the CTs are that of the host, divided by the number of CPU cores of the LXC container (per-core loadavg in Zabbix), instead of the load of the LXC guest itself. The commands...

    [SOLVED] Moving cluster operation traffic to another network

    I made a mistake when I created a 5-node cluster. I added all nodes by IP to the cluster and `pvecm status` now shows: Cluster information ------------------- Name: cluster2 Config Version: 5 Transport: knet Secure auth: on Quorum information ------------------ Date...

    [SOLVED] Azure to PVE migration problems

    I'm struggling with a seemingly simple task. I've copied the contents of an old Debian 8/Jessie VM from Azure to a PVE 6.1-7 host using rsync. I've set up boot, etc., and the VM does start booting, but I see the messages per attached image and it's stuck there forever. The root partition is a...

    [SOLVED] Weird issue with iptables on PVE 6.3 host - rules are in the kernel but ineffective

    I've upgraded a 5.2 system to latest 6.3 and experiencing something I've never before. It might or might not be PVE related, I have no idea. The gist of it, is I have a custom iptables firewall that loads without problems and does work. I had to allow a new IP for admin access, something like...

    LXC swap size change/regression between PVE 6.3 minor versions

    I've just upgraded a server to PVE 6.3 (pve-manager/6.3-3/eee5f901 (running kernel: 5.4.78-2-pve)) and see a sudden change in how LXC swap amount is presented. For a long time in older versions in LXC (maybe starting with 4.x) the swap size was shown and calculated as RAM+swap, but thankfully...

    pveproxy not listening on IPv6, only IPv4

    I'd like to access my PVE servers on their IPv6 addresses in a DC with native IPv6 available. Currently it's impossible as the pveproxy service is not listening on IPv6. The systems have proper dual stack setup, default (high) IPv6 preferences. Could it be fixed so the pveproxy service listens...

    High idle CPU load with kvm on latest PVE 5.1

    I've just installed a new system with latest PVE 5.1 with all updates on a Supermicro board with the Intel vulnerability patches in BIOS and a Xeon E5-2620v4. I experience high load on idle kvm VMs, about 6-7%. On the guest, CPU utilisation is 0-0.1%, all fine. I've tried multiple CPU types...

    apcupsd on pve 4.4 not working properly

    I know it's not exactly an apcupsd UPS support site, but I hope that someone else might have seen the same issues as I, as it possibly relates to the PVE kernel. I've upgraded 2 systems where previously we ran PVE 3.4 latest. These systems used apcupsd for smaller MGE/Eaton Ellipse UPS boxes...

    pve-zsync and VM freeze

    The pve-zsync tool is a very useful addition. If I'm planning to use it for regular VM snapshots, can it or does it issue an FS freeze when using the qemu guest agent? In other words, will I have such a consistent backup like when using vzdump with the agent?

    OpenVZ/Virtuozzo 7?

    Well, for many it might not be exactly news but the new release of OpenVZ/VIrtuozzo 7 is out as some kind of obscure standalone distro. Is anyone using it, or are there any plans to integrate it in Proxmox at some point in time? I know it's on a different road now with LCX but many important...

    Unlimiting LXC quota with Disk Size = 0 impossible in 4.1

    I'm evaluating the new PVE 4.1 environment and have stumbled upon a problem related to limiting disk quotas of LXC containters. I have an existing ext4 volume I want to use for CT storage, and there used to be the possibility in 4.0 to enter a 0 as quota. It used to turn on directory based...

    KVM guest is booting from host disk

    I've encountered a very strange and potentially very dangerous issue. I'm using virtio-scsi on top of a local LVM volume on a guest and instead of trying to boot from the virtual disk or CD image, it's trying to boot from the host drive. I can see the host's Grub menu on the guest's console...

    KVM IOMMU startup error

    I have a problem starting one of my VMs on a server wit a redirected PCIe card. It was working fine previously. I have tried all workarounds I posted here without success. This seems to be related to this bugreport. Is it possible that the related patch hasn't been incorporated in the PVE repo...

    KVM offline migration

    Please forgive me if it's documented somewhere but I haven't been able to find it. I've attempted to migrate KVM VMs from one HN to another via "qm migrate" on the newest PVE 3.3, but this is what I've got: vm1:~# qm migrate 150 vm2 Oct 11 15:28:02 starting migration of VM 150 to node 'vm2'...

    Analysing crashes

    I have a misbehaving PVE box, used for developent and some office tasks. Not mission critical, but it runs 7x24. It routinely crashes and reboots once or twice a week. Totally random, no correlation with load. I'm suspecting a HW failure but since I'm not at the console at reboots, I don't have...

    vzdump timeout

    I have a server where a few KVM VMs are replicated with DRBD. Almost every night when the backup runs, it times out at the same exact operation. A log excerpt is as follows: 105: May 27 02:15:04 INFO: Starting Backup of VM 105 (qemu) 105: May 27 02:15:04 INFO: status = running 105: May 27...

    ZFS on Proxmox and rsync

    I know it's not strictly a Proxmox question, but many folks here seem to use ZFS on Proxmox. What I have noticed is that compared to running ZFS on stock Wheezy kernel (3.2), running it on the latest Proxmox/RHEL 2.6.32 kernel, running times are more than doubled. Even when using rsync with -n...

    Intel IOMMU problems in 3.0RC2

    On a test server, I experience some strange log entries, pasted below. The host and the guest is working flawlessly so far, but I have some concerns about this. I haven't been able to find a definitive answer on the net on this subject. Should I be worried, or is this just a warning? I'm...

    Shutting down?

    Sorry if it has been discussed before, but I can't find a definite answer for the simple task of bringing down a cluster safely. Suppose I have a cluster with 4 nodes: 2 is in a HA configuration using DRBD, working fencing devices and config, and 2 other nodes for various purposes. All I want is...

    vzdump hook script is being ignored

    I'm running my vzdump backups using a simple hook script. It always gets to run when starting vzdump from the command line but never when the backups are started from cron (configured via the web interface). Am I doing something wrong? This is my config: # pveversion -v pve-manager: 2.1-1...
