Thanks a lot for your hint Simon.
I use "Other template" and it is (as far I understood) HVM.
When transfering big size image from another stand alone server to the
VM (ubuntu 11.10) I have 4 to 12MBit/s only (and I saw RTL-8139 during
installation of this ubuntu-VM).
I have tested it yet also with CentOS 6.2 on the same XCP-host (I used
"Other template" for the VM too) and got network speed a bit over
30MBit/s. It would be to fast for 100MBit/s, so I am a bit confused now.
On bare metal I am getting over 70MBit/s (the host is an HP DL385g7
I use bounded interfaces however only one port is connected to the
switch at the moment.
