We need something as sophisticated as this for debugging the domains.
Any volunteers?

e.g., here is a backtrace of a PF in ixgbe driver domain

cpu(0):Disable irqs
cpu(0):EXCEPTION: PAGE FAULT
cpu(0):Accessed Address: 4261415040
cpu(0):Error Code: 2

    r12: 0x105faf078,
    rbp: 0x105fb7540,
    rbx: 0x101e1c000,
    r11: 0x1,
    r10: 0xe,

    rcs: 0x8,
    rflags: 0x10246,
    rsp: 0x105f9ac70,
    ss: 0x10,
}
cpu(0):Backtrace:
cpu(0):frame #1  - 0x00000000010262a047

Would be nice to have the symbols resolved in backtrace
