    Connection error 596: Broken pipe

    Hi! I am managing a cluster running PVE v6, which currently includes two servers. My third node has been replaced but I am unable to join it. When I access hv102 using the GUI on hv101, I get "Connection error 596: Broken pipe". If I try to join hv103, I get this: root@hv103 ~ # pvecm add...

    [SOLVED] Converting virsh xml to proxmox vm.conf

    Hi! Is it safe to generate /etc/pve/qemu-server/XXX.conf files on my own? I have to migrate an OpenNebula-Cluster with more than 400 VMs, host by host. It would be much simpler if I can create the VM.conf on my own and place it on the host (mac address, vcpu config, etc.). The storage is Ceph...

    [SOLVED] Maximum CPU performance for VM (disabling CPU flaw mitigations)

    Hi! On a trusted system without multiple tenants it is safe to disable all CPU flaw mitigations. I already set and run these kernel params on the host: https://make-linux-fast-again.com/ Which CPU flags need to be set / unset under Hardware -> CPU for the VM? Based on the wording, I would for...

    Merging external ceph cluster into proxmox possible?

    Hi! Is it possible to merge an existing ceph cluster into a proxmox-cluster, where ceph is not configured? I am operating a rather large, standalone cluster with mixed clients (KVM using CentOS, Fedora and Debian), that I would like to extend by using the hyper-converged approach (creating new...

    Win 2019 VM suddenly dies with empty disk (Proxmox 6.0 + Ceph)

    Hi! I am observing a strange issue on one installation (3 Node Proxmox Cluster + external Ceph Cluster). Ceph is working fine as well as all other VMs. One VM, a Windows 2019 server crashs every night and loops with "No bootable device". When I boot recovery tools, I can see the disk but it's...

    OVS not forwarding traffic for debian 10 kvm

    Hi! I've moved some VMs from Fedora 30 KVM hosts to one running Debian Buster (virsh dumpxml / define). I need to clarify that I am not yet using a full deployment of proxmox, it's more a hybrid system of PVE kernel and QEMU. The VMs boot fine but their network is not working correctly. I am...
