1 - Yeha actually I noticed that, I am not able to create any new VMs from any 
other template. 

I just tried creating one Ubuntu instance , got this error in logs,

Template its saying not able to find, does exist at that location. I don’t know 
why its  throwing  that exception. 

2 - My ssvm, routers and storage all are fine. I have few production VMs 
running , with no issues. 

Yes my template was in ready , download completed state.

3 - For /usr/local/cloudstack/systemvm/ssvm-check.sh  , all check are fine.

4 - info I selected foe template is correct .

5  - of course..... :/ 

Its weird understating what's causing problem.

Subject: Re: problem creating instance from template

couple of questions for you Sonali


1. Are you able to build any new vms  using any OTHER  template that you 
already have. try to create a test vm

2. cloudstack pit stop checks from web interface  : from your ACS interface 
check if there are any errors ?

a ) can check if any of your hosts ,
b)  primary or secondary storage
c) systems vms
d) router vms

are in errored out state ?

e) is your template in READY state  , download completed .. ?


3. login to system vm and run the ssvm check 
/usr/local/cloudstack/systemvm/ssvm-check.sh  ,

also while on the ssvm , check the *SSVM Logs* - /var/log/cloudstack/cloud.log

4. when you registered your template did you chose the right OS version  etc ...

5.* does your server have the Intel Virtualization Technology (vt-x) or  amd-v 
in BIOS turned on , for windows you really need this on :-0*

i can only think of these issues & checks  ....
