Libguestfs - Jul 2016 - Re: Help: Can I access network inside libguestfs?

Hi All,

I mounted virtual disks of CentOS 6.4 using libguestfs. After mounting, I
tried to install some software using yum command. The yum command failed
because of DNS failure, I think I correctly configured DNS(/etc/resolv.conf
in the CentOS virtual disk).

I wonder is it possible to access network inside libguestfs?

Thanks,
Allen

By "mounting", do you mean with guestfish?  If so, it has a --network
parameter to enable networking for the guest.  Other tools have similar
options to enable and disable the networking, and few of them
(virt-customize, virt-builder, and virt-dib) have networking enabled
by default.

Thanks Pino for quick response.
Actually I use the libguestfs APIs in C++ program. Following your idea, I
think I should try guestfs_set_network for this.
Please correct me if I have any misunderstanding.

Thanks,
Allen
