[PVE-User] VM Guests too slow

[Germain Maurice]

Hi, i'm testing Proxmox in order to know if i could migrate all my 
physical servers to a Proxmox infrastructure
but i have a small problem when i use only 2 guests or one.

The VM guests are too slow, when i connect to the server via SSH it's 
anormally slow.
Completion with bash is very slow on guest contrary to the host.

On a host, I put an USB storage and made a "scp user at guest:~/file 
/mnt/usb", the transfer is slow and timeouted at the beginning or after 
a while... The size of the file is 200GB and the scp transfer stopped 
after 12GB.... :(

Any idea about the probable cause ?
Maybe a simple option to turn on or off....

Here are the cpu specs.
If you need some other informations, tell me.

Best regards,
Germain
