Hi everyone,

I confirm that the field "guestos_kernel_version" crash the REST API. When I change manually the value for a test VM, no more error. I try to update the kernel but the new one "2.6.37.6-24-default" causes a crash again. Not exactly the same error in the log but I think It fires an exception when parsin this value :

I am pretty sure its a bug in the API, it shouldn't bomb like that. It should do something more sensible in the case of a kernel version it can't parse properly.
