  1. AMD EPYC - Has NUMA ?

    Hello, I`m very confused with NUMA, as I read from docs you have a NUMA capable host if you have multiple CPUs (sockets). However I have installed Proxmox 6.1 (latest) on a AMD EPYC 16 core CPU, and the command to check available numa returns: available: 4 nodes (0-3) node 0 cpus: 0 1 2 3 16...
  2. Hohe CPU Auslastung

    Hallo zusammen, ich habe vor ein paar Tagen Proxmox installiert und bin fleißig am bastel. Ich habe nun 2 VM's (iobroker und OpenMediaVault) und 2 Container (Grafana und InfluxDB) erstellt und mir fällt auf, dass die CPU Auslastung sehr hoch zu sein scheint. Die einzelnen Container / VM's haben...
  3. [SOLVED] udisksd using lots of CPU

    I'm having a problem that has been reported by other Debian and Ubuntu users that udisksd is using lots of CPU. Right now I'm investigating workarounds rather than solutions so my question is: Is this service essential to Proxmox? What happens if I stop and disable it?
  4. Windows 10 KVM - CPU Problem

    Hallo an alle, Ich verwende seit einigen Tagen Proxmox und habe ein Windows 10 Server als KVM installiert. Es geht alles wunderbar, bis jetzt aber mir ist aufgefallen das, wenn man sich mit Remote verbindet und danach die Remote Verbindung wieder schließt am eigenen PC das die CPU Auslastung...
  5. [SOLVED] Lots of "CPUx: Package temperature above threshold, cpu clock throttled" syslog entries?

    Hi There, I have a NUC8i5BEH (Intel Core i5-8259U CPU) node and noticed that my proxmox syslog (running Proxmox PVE 6 but also occured on PVE 5.4) often outputs the following set of critical errors throughout the day: 23/07/2019 23:26:56 crit pve-host1.local kern kernel...
  6. CPU/core/thread terminology, and best allocating resources in a limited setting

    Hi all, I have two gaming VMs set up and running on a Ryzen 2700X. I'm quite impressed with the performance so far, although it's nowhere near what it manages natively. I think this may be in part due to how I have the VMs configured. The 2700X is an 8 core/16 thread CPU. I imagine the best way...

    KVM CPU flags ('ibpb', 'ssbd', 'virt-ssbd', 'amd-ssbd', 'amd-no-ssb', 'pdpe1gb')

    Hi, On a small cluster, I have 2 different CPU model for nodes, one is Broadwell, the others are Haswell. I usually set the CPU VM as 'host'. Indeed, live migrations works as expected from Haswell to Haswell and Haswell to Broadwell. But it crashes from Broadwell to Haswell, some flags are not...
  8. lxc-cgroup command returns nothing ?

    Hello, I'm trying to use this monitoring script for Nagios which monitor LXC cpu and ram usage. https://www.claudiokuenzler.com/nagios-plugins/check_lxc.php#CommandDefinition The script uses the command lxc-cgroup I tried lxc-cgroup -n 101 memory.stat which return nothing and no error...
  9. ZFS and overcommitted resources

    I've successfully built a Debian 9 host with Proxmox and ZFS. My understanding is that with the availability of resource sharing (e.g., "balloon" memory) it is common to overcommit resources. In other words, on a machine with 64GB, with several VMs running the same OS, I might be able to get...
  10. How to monitor LXC CPU usage ?

    How would I go about monitoring the CPU usage for an LXC container ? Solutions like in Nagios reads /proc but since the CPU are shared we get a lot of false positive. Example: CT A has 4 cores and uses 2 at 100% - 50% total CPU usage CT B has 2 cores which are shared with CT A - 100% CPU usage...
  11. inside a container, top does not work

    I have a container with 32 cores, and top show CPU consumption is always zero on the top panel, not in the per-process detail.
  12. Proxmox Installation in 2 physical CPU

    Hi, I would like to inquire if this possible in proxmox 3.3 version: -I have a server with CPU's(8 cores), so since I have 2 CPU(physical) after the installation the core that I have will be 16 cores? Right?
  13. 'host' cpu not working

    Hi, I am running Proxmox 5.2 on an AMD Ryzen 5 2600 Six-Core Processor, on a Gigabyte GA-AB350N-Gaming WIFI (rev. 1.0) motherboard. Everything is working fine and dandy, all virtualisation-related features seem to be working, I can do PCI passthrough etc, however, there's one thing I can't...
  14. CPU cores/sockets

    I have read conflicting recommendations regarding assigning cores/sockets. Looking for clarity: Hardware: 8 x AMD FX(tm)-8350 Eight-Core Processor (1 Socket) VM: Windows 10 Pro, acting as a NVR for IPCamera's. Container: Debian 9 running Plex media server and some other services...
  15. Intel IGD GPU Passthru Possible ?

    Hello, i run a Dedicated Server with a Intel i7 4770 CPU. That machine is running Proxmox 4.4 with 4 Windows Server 2012 VMs. Is it possible to share the IGD from the CPU on all 4 VMs at the same time ? If so maybe someone can point me in the right direction. Thank you very much
  16. Interne GPU in Proxmox verwenden

    Guten Abend, ich habe einen Dedicated Server mit einem Intel i7 4770 auf dem Debian Jessie mit Proxmox Virtual Environment 4.4-18 läuft. Jetzt suche ich nach einer Möglichkeit, dass meine VMs die auf Windows Server 2012 laufen auf die On Board Grafikkarte der CPU zugreifen können. Im Bios ist...
  17. Cores CPUs Threads

    I'm in a muddle with setting the number of cores, CPUs and Threads I use proxmox on a machine with 1x Intel Xeon D-1520 processor. This is a 4 core but 8 threads. I have only 1 VM running. Proxmox 5.1 summary for the node reports 8 CPUs However when setting the options for the processor in a...
  18. Proxmox CPU model kvm64 with PCID and AES flags

    Hi Proxmox, Is there a way to pass through the "aes" instruction to Guest VM by using CPU model kvm64? I noticed with recent PVE 5.1-35 we could enable the PCID flag on the CPU model from GUI. Would be nice to have AES flag as well. I know using CPU model host will give all the new CPU...
  19. "CPU limit" should be set rather than "Cores" when creating CTs

    The default CT creation dialog offers us to set number of CPU cores, but not CPU limit. However that causes CT to be locked on specific cores preventing it to use other cores under load, which might result in load spikes when two or several CTs get loaded on the same core. It somewhat tries to...
  20. Wrong CPU cache stats in all VM's

    Hi there, I've recently been dealing with some strange performance issues in cache-heavy applications. My host doesn't get properly loaded (50 ~ 70% max cpu) unless I perform CPU-only heavy tasks. When looking around I found out that all my VM's report oversized L2 and L3 caches, which is a...
