Dear Arjen , nice data you provided , im trying it right now. BTW , after installing virtIO drivers , memory usage looks ok on the proxmox gui (very nice!). Regarding CPU layout , I understood this: I should use just one socket , so in my case would be 1socket x 6 cores , total 6 vCPUs. If I notice that cpu usage goes high , lets suppose over 85% , I should add a second socket and enable NUMA.
I will change ide for scsi as you suggested. No problem if I need to re install OS. Regards. Leandro.
