[one-users] Generating core dump using SIGQUIT

[Shashank Rachamalla]

Hi

Are there any additional steps one should follow while compiling opennebula
on a x86_64 machine ?

I am making debian files from the compiled binaries and using them on other
x86_64 machines. should i keep anything in mind while doing this ?

I could have used the debian installer distributed by opennebula but i am
waiting for 1.4.2 version. current version is 1.4.0.
