Issues while upgrading from CUCM 7.1.2 to 7.1.3 in Vmware

Does CUCM 7.1.3 runs ok in VMWARE (ESX3.0) we are trying to upgrade but when it re-boots we get the following error -
kernel panic- not syncing: attempted to kill init

Tips to resolve this issue
  1. 7.1.2 bombs out in vmware if you dont configure a viable NTP server
  2. you cant upgrade from 7.1.2 to 7.1.3 in vmware esx 3.0 not sure why, but have heard license files are different
  3. get the bootable copy of 7.1.3 to install fresh on vmware 3.0 but couldnt do it
  4. eventually upgrade vmware to esx 4.0 and all should be good, you will still need a viable ntp server
  5. On CUCM 7.1.2, there's no code to detect VMWare. Thus you may install it on any Virtual Machine. CUCM just thinks it's a physical one.
  6. On CUCM 7.1.3, Cisco added code to detect VM. You'll have to use ESX 4.
