i just read back through where you stated you have "24 Intel Xeon X5650." what this probably means is that the /virtual host/ has 2x X5620, for a total of 12 physical cores and 12 logical cores via hyperthreading.
what your vps provider then does is figures out the 95%ile load over a given period to determine how many virtual machines they can squeeze onto each virtual host. typically they will determine they are able to create 2x-3x more virtual machines than the number of cores in the system -- usually counting hyperthreading "cores" as well. so on a 24 core host there are probably 48-72 virtual machines all sharing resources.
