Hello everyone, On CHR v7 running on Proxmox, we are experiencing a recurring issue where, after an uncertain period of normal operation, one specific virtio vNIC stops receiving traffic. Host side (Proxmox TAP interface): Packet captures confirm that inbound traffic (IP packets and ARP...

Hi, we have been using proxmox for many years. We have servers running different versions of PVE5.3, PVE6.2 and PVE7.0. We virtualize routers. This means that the VMs can have 10 to 20 nics. In this context we have noticed a problem after running the qm shutdown command the QEMU process receives...

Hello, I have successfully tested a pve VXLAN-EVPN setup with pci passthrough and switchdev (mlx5 mode eswitch) . However, the 127 VF limit is too restrictive. That's why I'm looking for another more scalable solution. I noticed that mellanox offers in addition to the usual sr-iov devices (PF...

Hello, When we introduced proxmox for virtualizing some routers we noticed that virtio nics order in qemu guest can shift when removing a vnics that is not the last one So we accept this behavior and defined best practice that consist to never remove virtio vnics. During sriov experimentation...

Hello, After several years of using proxmox to virtualize our routers we are now looking to increase network performance. Recently we are evaluating sriov as a virtio successor. It works very well ! For the moment it seems pretty stable and the performance is clearly superior to virtio. During...

Hi, Based on the documentation I understand that I need to remove qdevice before adding node to cluster. I don t know how to do that in secure manner. Otherwise I can restore node files like /var/lib/pve-cluster/config.db but I don t know what exact files I need to import and what the exact...

Hello, After proxmox installation, someone known if it is possible to change the contact email address specified in the proxmox installation wizard ? The documentation does not specifiy if we can edit the user.cfg file or if there is an option in proxmox WEBUI... thank you regards.

cpufreq-info analyzing CPU 0: no or unknown cpufreq driver is active on this CPU ... Does Proxmox team know this behavior ? is there a way to retreive scaling governor options ? thx

Hi, On proxmox 6.2-12 (Version pve-manager/6.2-12/b287dd27) kvm does not work and return an error when upgrading pve-qemu-kvm to version >= 5.0.0-8 It works when I downgrade to 5.0.0-5 kvm --version => undefined symbol: proxmox_restore_read_image_at_async is there an unsatisfying dependency...

Hello, On pve5.3 and pve6.2 we experience many disk errors with p840 hardware disk controller and hpsa module version 3.4.20.170 and fewer. Randomly the driver do not respond to IO requests which results in disk reset. a higher version (3.4.20.188) of hpsa seems to fix the pb...

Hello, Last Saturday I saw for the first time a strange system time changing behavior in a PROMOX 5.4 servers At 05:15 systemd report in syslog a time change to 14 Jun 07:38 HA components force node reboot after system watchdog failed After reboot system and hwclock are good and cluster is...

Hello, we already use proxmox 5.3 in production since many years, we are very satisfied We planned to add a new proxmox setup based on HA with two nodes + qdevice as explained in the Wiki as data backend we expect to use zfs pool (raid10) beacause it offer vm replication I m looking for the...

we currently use 2nodes cluster in proxmox 5.4 version with ZFS local sortage VMs are replicated with PVE native replication jobs. We have 2 migrations cases first one using offline migration VM is shutdown after a fresh replication task and started on remote node second one using online...

I am impressed every day by the quality of proxmox, whose main asset is its stability. thank you for this work currently on proxmox 5.4 we are not able to reach 10G and + The main reason is the linux kernel network stack design whose implies high context switches that affect performance The nic...

Hello proxmox community, we plan to migrate hundred of VMs from our old vmware platform to KVM proxmox appears as an ideal compromise but I'm experiencing a CPU load problem On proxmox HOST a single wget download consume 12% single CPU load at 11MBytes/sec (1518 packets size) On proxmox KVM...
