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...

    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...

    [SOLVED] CPU usage with LXC in webui

    Hello, I was under the impression that the reported CPU usage in the webui for LXC is in % but I'm having doubts. According to this picture: is the container using 10% cpu or it has a load of 10 (just like top would report) Thanks

    Hey Everyone, Back from ESXi-land with another valuable question, well two in fact. The question in the title is about measuring CPU resource usage in more detail, for example in Proxmox I love that there is an oi-delay counter. Questions: How would one go about measuring something like...

    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...

    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...

    [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?

    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...

    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...

    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...
