Like this perhaps: # LD_LIBRARY_PATH=/root/git/libvirt/src/.libs/ # /root/git/virshnodegetcachestats ret=0 nparams=10 L3.0: free=11520, max_contiguous=X. L3.1: free=11520, max_contiguous=X. Or: L3.0.free: 11520 L3.0.max_contiguous=X. L3.1.free: 11520 L3.1.max_contiguous=X. Not sure what is the preferred way to do this in libvirt. Otherwise, testing looks good now. -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
