  1. Enabling Numa

    Hi, I was looking at the docs about enabling NUMA because I have dual Xeon E5-2650 v2 processors on a dell R720 server. I have searched everywhere to find a good guide to enable NUMA according to the number of nodes and sockets. Anyone has tried it and could help? Cheers,
  2. Problems with TwinCAT, Proxmox and isolated cores on Windows

    Hello, I am experiencing some weird problems with TwinCAT (TC) in a Windows-VM. Because these problems do not occur with a different hypervisor (vmware ESX or HyperV), I suspect that the problem is related to Proxmox, KVM and/or their implementation of nesting. But first things first: I am...
  3. Hypethreading (SMT) and CPU settings

Situation: Main Node has 16 cores / 32 threads VM 101 has 32 vCPUs, because the database...

  7. [SOLVED] Creating templates with high amount of resources

    Hi everyone. I'm creating VMs using templates on thin lvm storage. I create the templates using various values for RAM and CPU, so template could have multiple CPUs or a big amount of RAM. Then on next builds, after clone I set CPU and RAM for new vm. My question is that does having high number...

  12. Common KVM processor

    Hello, When I checked the Task Manager in Windows 10 and viewed Performance, the selected CPU is worded "Common KVM processor" instead of name of the CPU? Intel i7 8600K. What can I do to make it read the CPU name instead of common KVM processor? Does correcting the name affect the overall VM...

    [SOLVED] [cpu::cores] pct in v5 diverges from documentation

    In proxmox5 cpu setting have diverged from all the documentation. It seems that cores setting is gone, as well as cpusets, and right now only cpulimit prevailed. First, documentation thinks otherwise. Very probably should be updated. Second, this may be a problem if the programs in the...
  18. CPU to use for VM (kvm64 vs host type)?

    As I create new VM for web site I'm in doubt if I should use kvm64 vs host type of CPU for VM. Choose host should looks like can give me more real cpu power (but I limited by real physical cores number), while kvm64 can be set to as high as 128, and (as I can imagine) will share the same...
  19. I cannot choose specific CPU type

    My CPU is i7-4770, but when I choose Haswell as the Processor type, it would not boot up, so I am using "Default (kvm64)" under VM setting, and it works OK. I have two questions: 1. Does Proxmox optimize the VM depending on the CPU type? Or it does not make much difference if I left it as...
