[ovirt-users] REST API - Problem when trying to retrieve vms list

Thanks for your quick reply, I found what is the origin of my error ... all the machines which cause problems are old OpenSUSE 11 with default kernel version "2.6.37.1-1.2-default". It seems that "1.2" part can't be parsed correctly. 

I don't know if it is a bug from API or a problem of the kernel version I'm using.

Looking at the exception and the code it appears you have something strange in guestos_kernel_version in vm_dynamic for that VM. In particular the revision part of that string. Its giving an index out of bounds, and the array it is looking at is split from that string on '-' so I am guessing the string in the database ends with - instead of -nn where nn is some number.

Now I don't know how that string is populated, but it must broken somehow.
