What exactly do you mean by CPU slice ? The CPU time used by
a domain since
it started ?

libvirt provides an API  virDomainGetInfo() for retrieving
stats about a
running domain. One of the fields in the struct it fills is
'cpuTime' which
is a running counter of CPU time allocated to the DomU since
it started,
measured in nanoseconds. You can access this from C / Python
/ Perl, or
just run 'virsh dominfo  [name | id | uuid]' from the
shell.

eg

# virsh dominfo demo1
Id:             6
Name:           demo1
UUID:           7c29eaa6-68e3-1891-abef-7334079927a1
OS Type:        linux
State:          blocked 
CPU(s):         2
CPU time:       14.8s
Max memory:     723968 kB
Used memory:    723776 kB
