Hi, I am using libvirt api to create an app, I am facing a problem. I can connect to connection object 20 number of times in programm after that it gives connection object null. Here is the sample code. Normally code should run 1000 times but it only runs 20 times Filename: list.cpp #include<pthread.h> #include<stdlib.h> #include<stdio.h> #include<malloc.h> #include <iostream> #include<string.h> #include <libvirt/libvirt.h> #include <libvirt/virterror.h> static int count; static void customErrorFunc(void *userdata, virErrorPtr err) { } int main() { virConnectPtr conn; for ( int i=0; i< 1000;i++) { conn = virConnectOpen("qemu:///system"); if (conn == NULL) { fprintf(stderr, "Failed to open connection to qemu:///system\n"); printf("Failed to open connection to qemu:///system\n"); virConnectClose(conn); return NULL; } printf("Hello %d\n",i); virError err; virSetErrorFunc(NULL, customErrorFunc); int j; int numDomains1,numDomains2,numDomains; int *activeDomains; numDomains1 = virConnectNumOfDomains(conn); activeDomains = (int*)malloc(sizeof(int) * numDomains1); numDomains1 = virConnectListDomains(conn, activeDomains, numDomains1); for (int j = 0 ; j < numDomains1 ; j++) { virDomainPtr dom; dom = virDomainLookupByID(conn,activeDomains[j]); free(dom); } free(activeDomains); count--; virConnectClose(conn); } } Output: Hello 0 Hello 1 Hello 2 Hello 3 Hello 4 Hello 5 Hello 6 Hello 7 Hello 8 Hello 9 Hello 10 Hello 11 Hello 12 Hello 13 Hello 14 Hello 15 Hello 16 Hello 17 Hello 18 Hello 19 Failed to open connection to qemu:///system Failed to open connection to qemu:///system Can any one tell me where I am going wrong.
