C:\AutoInstall\server\log\ 2012-05-18.log
1) Confirm the error virtual machine and the error time:
According to the error time, we find the following error log, we know this problem is caused by the script configuring the DHCP Scope failed.
2012-05-19 02:19:48,697 Thread:[1680] Priority:[ERROR] Class:VDS_management_studio.source.application.installation.DHCP.DHCPsetUp Method:setUp2_configDHCPServer Line:0 Excute Command <netsh  dhcp server scope add iprange > Failed.
Hence, we have confirmed the reason of creating the virtual machine failed.

After happening this error, check the detail error through the logs firstly, then take the corresponding measures to settle or avoid this error.
