  1. Server virtualization

    Hello, there are 11 vms on my Ryzen 7 5800x, how can I virtualize them in the most efficient way? Most of my users have a minecraft server. I can't have performance problems. What is your suggestion? How should I adjust settings such as processor settings?
  2. Degraded CPU performance inside LXC

    Hello everyone I am new to Proxmox, coming from a VMware / Hyper-V background. During evaluation tests I came accross the following issue: When running a certain workload in a LXC container I get degraded CPU performance compared against a QEMU / Hyper-V VM. After some research / benchmarking...
  3. LXC showing hostnode CPU load, not container CPU load %

    After installing proxmox and create some LXC CT, I found all of the created vps is showing hostnode CPU load. Not container CPU load % like openvz does. How we can fix this problem?

  5. cpu=host enables nested virutalization… but is way slower than cpu=kvm64… forum and wiki are contradictory

    Hi to get Ubuntu to work under Windows 10 (and avoid the "Please enable the virtual Machine Platform Windows feature and ensure virtualization in the BIOS"), I have to set the cpu type to host. But then guest if very slow. Which is expected according to Proxmox staff @Stefan_R ...

  8. Performance differential between a VM vs LXC?

    Curious: has anyone done an analysis of what the memory and processors utilization differentials are between a virtual machine and an LXC container? I think it would be interesting to see how much more RAM a large and small virtual machine may use compared to both a large and small a container...
  9. VM CPU Performance

    Hi, I've noticed that the CPU performance of the VMs is well below what it should be. I have a newer one that has a CPU with less performance than this newer one, and the VM on geekbench delivers what it should deliver. A VPS on the newer one has less performance than the previous generation...

  12. Setting CPU type to anything but Default KVM64 results in boot loop

    I'm very new to Proxmox and Hypervisors in general. VMs install and run with no issues when the CPU type is set to Default KVM64, but setting to Host (or if I specify the processor type as Westmere, which it is, it errors the same way) will result in an error when installing OS after the reboot...
  13. ZFS: Hohe CPU last

    Hi, Ich habe hier noch ein altes Board mit einem Intel J4005 rumliegen und habe als Testsystem Proxmox draufgehauen. Proxmox selbst läuft auf einer NVMe SSD, zudem habe ich eine weitere SATA SSD und eine HDD als ZFS Single Disk hinzugefügt. Bei einem Test via Samba ist mir aufgefallen, dass...
  14. MSWX VM refuses to boot or bootloops on cpu change

    There is one ms windows vm which behaves quite peculiar. Changing the CPU away from anything kvm64 (> host) results in an inability to boot. Even a reboot into safe mode use msconfig does not work as per usual. Despite having configured a windows10 .iso to boot from the 'press any key to boot...

  16. Correct configuration for VM Processors

    Hello, I have Proxmox VE 6.3-3 running on a Dell Server with an Intel® Xeon® Processor E5-2680 v3 (2x 12 core). Hyperthreading is enabled, so a maximum of 48 cores are available. What is the correct configuration to allow a VM to use all 48 cores? I tried setting Sockets to 2 and Cores to 24...

    Hi, I have only single VM, running with ParrotOs, when i update my system my vm and node freeze like picture: I have Lenovo ThinkCentre M700 with 4 Ram and 150 SSD. Thank you.
  19. Server freezes or restarting automatically (mce: [Hardware Error])

    I got a new server and found some issues during loading and adding new VMs. At first it froze, but after Proxmox upgrading it restarts automatically. It prints 'Start all VMs and Containers' in the tasks. Provider tested its hardware and didn't found any problems. But I can see mce: [Hardware...
  20. Question regarding vCPU for KVM

    We are looking to enable hotplug for the CPU for KVM guests. I've seen that it's only possible with vCPU and not Sockets nor Cores. Assuming the host has 32 cores, would it be best practice to set Sockets: 2 Cores: 16 and set the vCPU to 6 or according to the guest CPU need. If I understand...
