<pre wrap="">We had an issue with DHCP yesterday which lead me to test UDP traffic from the VM we loaded on our VMware ESXi box. I found that after around 25Mbps UDP starts to lose packets, and it gets worse and worse the fast you go. I tried every virtual card type (e1000, VMXNET2, VMXNET3) with the same results. I even tried on different servers, and they were also showing UDP packet loss. Physical boxes on the same network showed no packet loss until I pushed their NICs to the limit (1Gbps).
Has anyone faced DCHP problems by using a VM because of this? If so, were you able to fix it or did you just move back to a physical box?
Thanks,
Joseph B.

Did you dedicate a nic to the virtual machine or are going thru a
vswitch. We got dramatically better results by taking the nic out<br>
of the vswitch dedicating it to the virtual machine. This was in a
packet capture environment.<br>
