NO resolv.conf in kvm zone

[marcheschi]

Hi
I tried to make a kvm zone using ubuntu-certified-17.10 image from Smartos repos.
The kvm zone is created successfully but without the /etc/resolv.conf file.
Thank you
Paolo

Hi Paolo,

Thank you for the information. These are not our official images, but we will try to reproduce the problem and then let you know if it can be fixed.

/etc/resolv.conf should be configured properly in our KVM images (usually set to the VMS_VM_RESOLVERS_DEFAULT DC setting.

Confirmed.
/etc/resolv.conf is correctly configured in the ubuntu-certified-16.04 image.
In ubuntu-certified-17.10 it stopped working probably due to some changes in cloud-init.

We will try to fix this in the next release.

Thank you for letting us know.

Hi Paolo,

Originally, I was thinking that we can fix this by adding some metadata for cloud-init. Howerver, this is something that needs to be fixed in the image.

After playing around with the ubuntu-certified-17.10 image, I found that /etc/resolv.conf is a broken symlink to ../run/resolvconf/resolv.conf. There are at least two options to fix this:

• rm -f /etc/resolv.conf; ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf (the systemd-resolved service maintains /run/systemd/resolve/resolv.conf from the first boot)

OR

• apt-get install resolvconf

I've sent the information to the smartos-discuss mailing list.
