<P><FONT SIZE=2>Hi...<BR>
<BR>
This is my program for Domain Migrating using virDomainMigrate() Function....<BR>
<BR>
<BR>

if (dom == NULL)<BR>
{<BR>
fprintf(stderr, "Failed to find Domain %d\n", id);<BR>
goto error;<BR>

int main(int argc, char **argv) {<BR>
int id = 0;<BR>
<BR>
/* NULL means connect to local Xen hypervisor */<BR>

<BR>
error:<BR>
if (conn != NULL)<BR>
virConnectClose(conn);<BR>
return(0);<BR>
}<BR>
<BR>
<BR>
When I Compile this by the command<BR>
<BR>
gcc `pkg-config --cflags --libs libvirt` migrate1.c<BR>
<BR>
I got the error...<BR>
<BR>
migrate1.c: In function ‘migrate’:<BR>
migrate1.c:67: warning: assignment makes pointer from integer without a cast<BR>
/tmp/ccmgmkE1.o: In function `migrate':<BR>

collect2: ld returned 1 exit status<BR>
<BR>
Can you help me...<BR>
<BR>
