[PVE-User] cores and threads

[Miguel González]

Hi,

  I have a Proxmox 4 host running Intel Xeon W3520 with 4 cores and 8
threads with 32 gb of RAM. This host has 5 VMs.

  Two VMs has quite heavy CPU usage (two web servers), another one quite
moderate (email server, but only with a few accounts) and two DNS
servers with low usage.

  How many sockets and cores can I allocate?

  Can I enable NUMA? I get:

  numactl --hardware
available: 1 nodes (0)
node 0 cpus: 0 1 2 3 4 5 6 7
node 0 size: 32165 MB
node 0 free: 164 MB
node distances:
node   0
  0:  10


  I have searched on Google and the information is not very clear about
how many sockets and cores I can set in a VM.

  Thanks!

  Miguel
