Re: [libvirt] Host IP Address



Thanks Max,

But then again, how would I resolve the IP Address from the hostname? Can
you please guide me on this.

In short:

struct hostent *hostent;
hostent = gethostbyname (char *hostname);
if (hostent) {
       for (i = 0; hostent->h_addr_list[i]; i++)
printf ("%s, ", hostent->h_addr_list[i]);
printf ("\n");
}

I got the idea of what to do. Thanks.

Thanks and Regards
Sagar Barve

Hi!

Thanks for such a quick reply.

No problem :)

Did I get you right, that you have a 'virDomainPtr' as basis and want a
mapping
from that to the IP?
Yes. Thats what I want to do.

I guess one way could be to get the virConnectionPtr
 conn_ptr = virDomainGetConnect (domain_ptr);

And then query the hostname
 virConnectGetHostname (conn_ptr);
or the uri
 virConnectGetURI (conn_ptr);

and resolve the hostname or extract the IP/host from the URI and
resolve that.

Yes, I thought of this too. But I was hoping that the LibvirtAPI has some
way of giving me the host IP Address directly, instead of resolving it
myself.

I don't know of any and I wouldn't know which IP to choose if there
were multiple.

But then again, how would I resolve the IP Address from the hostname? Can
you please guide me on this.

In short:

struct hostent *hostent;
hostent = gethostbyname (char *hostname);
if (hostent) {
       for (i = 0; hostent->h_addr_list[i]; i++)
printf ("%s, ", hostent->h_addr_list[i]);
printf ("\n");
}
