When running on AMD platforms, the legacy hardware emulation is extremely unreliable. In particular, the IRQ0 timer interrupt is likely to simply stop working, resulting in a total failure of any code that relies on timers (such as DHCP retransmission attempts). Work around this by using the 10MHz time counter provided by Hyper-V via an MSR. (This timer can be tested in KVM via the command-line option "-cpu host,hv_time".)
