Attached is a patch, implementing Domain.pin_vcpu method.
I have tested it locally and it works. Here is my test code:

require 'libvirt'

    conn = Libvirt::open("")
    dom = conn.lookup_domain_by_name("centos52")

After running it, I can verify via virsh that it does pin CPUs  

virsh > vcpuinfo centos52
VCPU:           0
CPU:            2
State:          blocked
CPU time:       40.8s
CPU Affinity:   --yy

However, when I try this method from test/tc_connect.rb it fails:

# rake test
(in /home/lord/src/ruby-libvirt)
Loaded suite /usr/lib/ruby/gems/1.8/gems/rake-0.7.3/lib/rake/ 
libvir: error : this function is not supported by the hypervisor:  
Finished in 0.006319 seconds.

   1) Error:
SystemCallError: unknown error - libvir call virDomainPinVcpu failed
     ./tests/tc_connect.rb:113:in `pin_vcpu'
     ./tests/tc_connect.rb:113:in `test_domain'

5 tests, 60 assertions, 0 failures, 1 errors
rake aborted!
Command failed with status (1): [/usr/bin/ruby -Ilib:ext/libvirt "/usr/ 

(See full trace by running task with --trace)

I will appreciate if somebody could help me to figure out why it is  

I might need to implement couple more methods, so if there are any  
remarks on
my code, I will appreciate your feedback.
