I've just gone live with a couple of VM'd Windows guests, an SBS 2011 standard server and a 2008 r2 (sbs 2011 premium) box, on the same physical host (CentOS 6.2) with the most current Virtualbox (4.1.
, the phsical box has a current generation Xeon CPU and 32GB of RAM. It's an Intel MB.Both installs are working well except for their network performance, which is dismal (and disasterous!)
VBOxManage list --long for the two VM's is below, I used the virtio network drivers for both guests (which are both 64 bit)
Can anyone see what may be causing these to be so slow and what I can do to speed them up?
