[one-users] OpenNebula 3.4 and Esxi 5.0- image cloning task throws error

Tue May 8 08:32:44 PDT 2012

Tino,
Thanks for the reply.
I compared with only the Shared Transfer driver in both. Currently I am on travel and I will post some more details like  "Time taken"  on both versions etc once I am back to work. 
Regards,
Anil

Hi Anil, 

So which drivers are you comparing exactly? I mean, are you comparing 
SSH drivers in ONE 3.2 vs ONE3.4? Or are you trying all the 
combinations? 

Operations in ONE3.4 regarding cloning of files are done in the ESX 
host, whereas it was done in the front-end in ONE3.2. It may be that 
performance is a tad worst in the low load scenario in ONE 3.4 vs ONE 
3.2 in SHARED drivers (SSH should pretty much be the same), but on the 
other hand the scalability is much better (in terms of responsiveness 
of the front-end). Please let me know if your findings indicates 
otherwise. 

Regards, 

-Tino
