I have pfsense box running on another 860 that works fine .

I dont know how xen assigns Mac to network what if Mac address is
diffrent on network card than on virtual will that cause issues. Is
there a way to assign network card to hvm on this box
http://wiki.xensource.com/xenwiki/XenNetworking explains well, how the MAC's are assigned. It has nice pictures, you will like it. In short, the VM's network card should not have the same MAC address as the physical card. The MAC for the virtual card is generated on the fly each time the VM is started, or specified via config file.

And yes, you can give your HVM the whole network card, with PCI passthrough. http://wiki.xensource.com/xenwiki/XenPCIpassthrough.html explains how.

    Tricky setup you have got there. I would suggest to slow down, and
    make things work one by one, not all together at the same time.

    Double check, if you are plugging right stuff in the right jacks.

        Now my cable modem can't obtain ip address from Comcast.

    Is your modem configured as router, or as a bridge? If it's a
    router, ask the question to Comcast support, whatever is it's issue,
    it should have nothing to do with Xen or your Pfsense.
    If it's a bridge, consider to make it work in router mode first with
    your pfsense VM.

        Should I setup the xenbr1 bridge to dhcp ?

    Generally, "42" would be the answer.
    Describe your network topology before asking that.

        Do I need to configure virtual network card to have same mac address
        that my network card

    Generally, no. Leave each MAC address on the place it belongs,
    unless specifically need to change that and know exactly why.

    If the modem is acting as bridge and your ISP expects to know your
    computer's MAC address, consider asking them to register your VM
    "external" MAC. Tell them you are going to use your own router, and
    this is the MAC address of it's WAN interface.
