tools/kvm_stat: indicate dead guests as such
For destroyed guests, kvm_stat essentially freezes with the last data displayed. This is acceptable for users, in case they want to inspect the final data. But it looks a bit irritating. Therefore, detect this situation and display a respective indicator in the header. Signed-off-by: Stefan Raspl <raspl@linux.ibm.com> Signed-off-by: Radim Krčmář <rkrcmar@redhat.com>
