[libvirt-users] unknown procedure: 159

Hi, I started using libvirt few days back...while using virDomainMemoryStats API, got "unknown procedure: 159" runtime error code is ------------------------------------------------------------------------------------------------------------------------------------- virDomainMemoryStatPtr statPtr; statPtr = malloc(VIR_DOMAIN_MEMORY_STAT_NR* sizeof (virDomainMemoryStatStruct)); unsigned int flags=0; int Ret; Ret = virDomainMemoryStats(domPtr,statPtr, VIR_DOMAIN_MEMORY_STAT_NR,flags); ------------------------------------------------------------------------------------------------------------------------------------- Machine details: ------------------------------------------------------------------------------------------------------------------------------------ [root@wlng-ppcore-nd3 hellolibvirt]# uname -a Linux wlng-ppcore-nd3 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:39 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux [root@wlng-ppcore-nd3 hellolibvirt]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 5.5 (Tikanga) ------------------------------------------------------------------------------------------------------------------------------------ virsh details: [root@wlng-ppcore-nd3 hellolibvirt]# virsh version Compiled against library: libvir 0.8.1 Using library: libvir 0.8.1 Using API: QEMU 0.8.1 Running hypervisor: QEMU 0.9.1 ------------------------------------------------------------------------------------------------------------------------------------ There are two libvirtd installations here.. ------------------------------------------------------------------------------------------------------------------------------------ [root@wlng-ppcore-nd3 sbin]# pwd /usr/sbin [root@wlng-ppcore-nd3 sbin]# ls -l libvirtd -rwxr-xr-x 1 root root 380064 Jun 10 02:33 libvirtd [root@wlng-ppcore-nd3 sbin]# ./libvirtd --version ./libvirtd (libvirt) 0.6.3 ------------------------------------------------------------------------------------------------------------------------------------ [root@wlng-ppcore-nd3 sbin]# pwd /usr/local/sbin [root@wlng-ppcore-nd3 sbin]# ls -l total 3084 -rwxr-xr-x 1 root root 3152977 Jun 10 01:25 libvirtd [root@wlng-ppcore-nd3 sbin]# ./libvirtd --version ./libvirtd (libvirt) 0.8.1 ------------------------------------------------------------------------------------------------------------------------------------ found a link which mentions libvirtd can be old hence this error is possible... not sure how to configure the latest libvirtd? How to solve "unknown procedure: 159" runtime error? Thanks, osvdev
