Getting errors when try to start Debian XEN HVM VM with more than 4 vif's
Hello 


I already searched the internet for this problem and unfortunately I
didn't come across any helpful information and thought I'd turn to you I
hope you can help me with this.

I've been trying to set up a PfSense firewall on my Debian XEN server
for some time now, this works fine until I try to add a fifth (with four
it works) interface to the "hvm" VM, then the VM won't start and it
comes to the errors described below.  When i try to add exactly the same
interfaces to a normal paravirtualized Debian VM, it works.
