ISSUE
============
Instance fails to start after unsuccesful compute offering upgrade.

 
TROUBLESHOOTING
==================
We observed VM instance get compute values "cpuNumber","cpuSpeed","memory" removed from table
"user_vm_details", which cause instance fail to startup next time on XenServer 

mysql> select * from user_vm_details where vm_id=10;

REPRO STEPS
==================
1. Set global setting enable.dynamic.scale.vm to true
2. Create a custom  Compute Offerings A
3. Create a VM instance apply A, ie. cpuNumber=1,cpuSpeed=1000,memory=512M
4. Create another custom Compute Offerings B
5. Change service offering to B, ie. cpuNumber=2,cpuSpeed=2000,memory=4096M (ensure 4 times
over previous memory size), then you will encounter scaling failed
6. Stop VM instance , you will never startup again

EXPECTED BEHAVIOR
==================
Succeed Startup VM instance
 
ACTUAL BEHAVIOR
==================
Fail to start instance
