Hi Guys. Im writing a program that connects to Xen and gets some information (scheduller and memory informations). When executing the program using the libvirt 0.3.3 its working fine, BUT when running using libvirt 0.4.4 it doesnt work. I dont get any error message when compiling or executing, but the informations doesnt come. -> Using libvirt 0.3.3 # gcc -Wall -lxenstore `pkg-config --cflags --libs libvirt` test.c -o test # ./test DOMAINS IDENTIFIED 2 DomID: 0 Max Mem: 4294967292 Sched: 256 DomID: 3 Max Mem: 262144 Sched: 256 # xm list Name ID Mem VCPUs State Time(s) Domain-0 0 616 2 r----- 4751.9 vm01 3 256 2 -b---- 379.7 -> Using libvirt 0.4.4 # gcc -Wall -lxenstore `pkg-config --cflags --libs libvirt` test.c -o test # ./test DOMAINS IDENTIFIED 0 # xm list Name ID Mem VCPUs State Time(s) Domain-0 0 481 2 r----- 89.8 linuxprv01 1 512 1 -b---- 10.8 I executed the same program in other server, with 0.4.4 version, and got the same problem. Is there any difference between those versions? Thanks in advance. Att. Artur Baruchi
