  4. Freez issue with latest Proxmox 6.3-4 and AMD CPU

    It seems downgrading to 6.3-3 using below commands will fix the issue: apt install pve-manager=6.3-3 reboot The sign of issue is that some VMs show CPU usage of exactly 0% and VNC will not be able to connect and also you can see lines like below inf /var/log/syslog VM 1116 qmp command failed...
  5. Freez issue with latest Proxmox 6.3-4 and AMD CPU

    In last few days my latest Proxmox installation on AMD CPUs has VM freezing issue. My CPUs in different servers was in two models: 1.AMD Ryzen 9 3900 12-Core Processor 2. AMD EPYC 7401P 24-Core Processor On both I can see Windows VMs freez after free hours, and stop/starting them will temporary...
  6. Live-migrate outside of cluster

    I have few PVE nodes and some times I need to transfer VMs between them but they are not in a cluster. Does anyone know a trick on how to live-migrate a VM between nodes which are not in a cluster?
  7. Hetzner servers with Proxmox are unsable

    Note: It may be important that I'm installing Proxmox on Debian 10 and I'm not using Proxmox ISO to install it.
  8. Hetzner servers with Proxmox are unsable

    As far as I have tested with more than few servers, whenever I install Proxmox on a Hetzner server for example AX or PX lines, my servers go down and when I check them out with remote KVM the screen is blank. The only temporary solution is to reboot the server and they just come up fine. Any...
  9. Why we can't have more than 4094 vlan tag ID on OVS with GRE overly?

    Thanks for the info, would you please let me know how can I configure VNI id of an interface in Proxmox using OpenVSwitch Bridge?
  10. Why we can't have more than 4094 vlan tag ID on OVS with GRE overly?

    In vxlan, is VNI equevalent of vlanID ? by setting VNI to each interface of a VM, are we isolating the traffic of that customer of others?
  11. Why we can't have more than 4094 vlan tag ID on OVS with GRE overly?

    My case is to offer private network to our many clients, each client may have more than 1 private network and therefor 4095 vlan tag is not enough to fully isolate each client's private network.
  12. Why we can't have more than 4094 vlan tag ID on OVS with GRE overly?

    Using an other field, can't we assign both VLAN field IDs from Proxmox configs? If so then we can have more than 16 million separated private networks. right?
  13. clone an LVM on shared LVM storage

    For purpose of fast provisioning we need to be able to clone a base LVM, which is raw OS image on it, Is that possible like what below link said in shared storage environment? ( of course we have SAN storage device) http://www.andybotting.com/how-do-you-clone-an-lvm-partition
  14. How to disable Spectre , Meltdown , ... kernel patches

    In latest versions of kernel 5.2+ we can disable mitigations by "mitigation=off" kernel command, but as Proxmox 6 is using kernel 5.0 I've disabled them by using this grub config GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0 pti=off spectre_v2=off nospec_store_bypass_disable mds=off"
  15. How to disable Spectre , Meltdown , ... kernel patches

    For better Ceph performance, I need to disable all kind of kernel protections for CPU vulnerabilities, Is there any guide on how to ask kernel in Proxmox to do so? Servers are being used only for Ceph so I have no security concerns regarding disabling CPU vulnerabilities.
  16. Why we can't have more than 4094 vlan tag ID on OVS with GRE overly?

    That's correct, but doesn't OpenVSwitch supports IEEE_802.1ad ?
  17. Why we can't have more than 4094 vlan tag ID on OVS with GRE overly?

    I setup OVS switch on 10 nodes which are interconnected via GRE tunnels, but I can see Proxmox is not letting us create more than 4094 vlans because tag ID larger than 4094 is not validated in Proxmox interface or API. Is there any restriction based on GRE overlay that prevent us having more vlans?
  18. Prometheus guest exporter

    As far as I know recent versions of GuestAgent support executing any commands, therefor it should be possible to monitor guests from host, is that true?
