Bug 23766: Document error during debootstrap

$ qvm-pref --set [vmname] kernelopts 'nopat vsyscall=emulate'

----

Error during debootstrap image creation

---------------------------------------

If the debootstrap-image-.log contains errors similar to the following:

W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/zesty/InRelease

   Temporary failure resolving 'archive.ubuntu.com'

Check /etc/resolv.conf on the host to see if the nameserver is set to

127.0.0.1. This can happen when runc performs a bind mount of

/etc/resolv.conf and the host system is running systemd-resolved.

sudo systemctl disable systemd-resolved.service

sudo service systemd-resolved stop

Put the following line in the [main] section of your

/etc/NetworkManager/NetworkManager.conf:

dns=default

Delete the symlink /etc/resolv.conf

rm /etc/resolv.conf

Restart network-manager

sudo service network-manager restart
