Hyper-V cluster in Server 2008 questions

Source: microsoft.public.virtualserver
Sent: 08/08/2008
From: Daveyd
Message:

I have setup a 2 node cluster in Server 2008. I am using Hyper-V and have 1
VM. The VM has 2 dynamically expanding VHDs associated with it

The 2 physical nodes are connected to an iSCSI SAN. I have made available 2
LUNs on the SAN to the 2 nodes. They are presented to the nodes as the Q:
and F: drive. The Quorum resides on the Q: drive and the VHDs reside on the
F: drive.

When I failover the VM to another node, I get the following message in the
System Log:

Log Name: System
Source: vhdparser
Date: 8/8/2008 10:32:23 AM
Event ID: 1
Task Category: None
Level: Warning
Keywords: Classic

Description:
The parent virtual hard disk appears to have been modified without using the
differencing virtual hard disk located at
"...\\VM_Disk2_8B00376C-FFEA-4B6A-9100-31AD08694698.avhd". Modifying the
parent virtual hard disk may result in data corruption. It is strongly
recommended that you lock the parent virtual hard disk to prevent this in the
future. If you recently changed time zones on your computer, you can safely
continue using this virtual hard disk.

Any ideas?

Also, I have 3 Physical NICs on both servers. 2 embedded Broadcom NICs and
a 2port Intel NIC.

The 2 emdedded Broadcom NICs are conneted to the iSCSI network. One of the
ports on the dula port Intel NIC is connected to the Public LAN and the other
port is connected to the other server for the cluster Heartbeat.

When I created the cluster, I chose to bind the Virtual Network to the
Public LAN NIC. The cluster created a 4th NIC which looks to be a Virtual
NIC. Is that what it was supposed to do? I am used to VS 2005 and it just
using the physical NIC
