Hi...
This is my program for Domain Migrating using virDomainMigrate() Function....
#include <stdlib.h>
#include <stdio.h>
#include <libvirt/libvirt.h>
static virConnectPtr conn = NULL; /* the hypervisor connection */
static int
checkDomainState(virDomainPtr dom)
{
virDomainInfo info; /* the information being fetched */
int ret;
ret = virDomainGetInfo(dom, &info);
if (ret < 0)
{
return(-1);
}
return(info.state);
}
static void
migrate(int id)
{
virDomainPtr dom = NULL; /* the domain being checked */
virDomainPtr dom1= NULL;
int ret, state;
/* Find the domain of the given id */
dom = virDomainLookupByID(conn, id);
if (dom == NULL)
{
fprintf(stderr, "Failed to find Domain %d\n", id);
goto error;
}
state = checkDomainState(dom);
if ((state == VIR_DOMAIN_RUNNING))
{
dom1=virDomainMigrate(dom,conn,VIR_MIGRATE_LIVE,NULL,NULL,0);
if(dom1==NULL)
{
fprintf(stderr,"Failed to migrate");
}
else
{
fprintf(stderr,"migrate successfully");
}
}
error:
if (dom != NULL)
virDomainFree(dom);
}
int main(int argc, char **argv) {
int id = 0;
/* NULL means connect to local Xen hypervisor */
conn = virConnectOpen(NULL);
if (conn == NULL) {
fprintf(stderr, "Failed to connect to hypervisor\n");
goto error;
}
if (argc > 1) {
id = atoi(argv[1]);
}
if (id == 0) {
int i, j, ids[10];
i = virConnectListDomains(conn, &ids[0], 10);
if (i < 0) {
fprintf(stderr, "Failed to list the domains\n");
goto error;
}
for (j = 0;j < i;j++) {
if (ids[j] != 0) {
id = ids[j];
break;
}
}
}
if (id == 0) {
fprintf(stderr, "Failed find a running guest domain\n");
goto error;
}
migrate(id);
error:
if (conn != NULL)
virConnectClose(conn);
return(0);
}
When I Compile this by the command
gcc `pkg-config --cflags --libs libvirt` migrate1.c
I got the error...
migrate1.c: In function ‘migrate’:
migrate1.c:67: warning: assignment makes pointer from integer without a cast
/tmp/ccmgmkE1.o: In function `migrate':
migrate1.c:(.text+0xd4): undefined reference to `virDomainMigrate'
collect2: ld returned 1 exit status
Can you help me...
with regard,
Mano
