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

Regards,
Dan.
