Low hashrate on Xeon E5-2620 about xmr-stak-cpu

[psychocrypt]

please post the config cpu.txt and the full output of the miner (from the first line)

If you do not set the CPU type for the VM to "native" or "passthrough" then it will not have all the CPU features ("Qemu CPU" is not a Xeon...)

Your hashrates seem to match a non-AES processor, therefore I suspect the AES feature is not being provided to the VM.

I run my miners directly on the Proxmox installation, using a VM is kind of like putting on two pairs of socks - it works but why, it is never faster, brings problems, causes blisters. :)
