Right, my hack is almost the same as --no-hosts, it just doesn't require patching libvirt. Do you need that entry in your /etc/hosts? If you have a real DNS name, you might not need it at all. If not, but you have a static IP address, you could use that in the hosts file instead of 127.0.1.1. --

Thanks Nathan to share you workaround as well, but IMHO it is "just as good" as the --no-hosts flag. In that I mean while it prevent the reply of 127.0.1.1 for the Host it also stops any other entry in Hosts to be used (which users might want or even already rely on). Darragh, Jason and Serge trie

I had the same problem (on 16.04.02) and came up with a rather dirty, but quick and effective workaround. Simply remove the libvirt-dnsmasq user's ability to read /etc/hosts: sudo setfacl -m user:libvirt-dnsmasq:--- /etc/hosts The libvirt dnsmasq instances will syslog a complaint when they s

[Touch-packages] [Bug 1326536] Re: libvirt's dnsmasq setup will read /etc/hosts on the host, resulting in odd resolution behaviour on the VM

Did some more testing (found how to adjust libvirts dnsmasq.conf and restart it to pick up conf changes): To test, get the dnsmasq pid using the vagrant-libvirt.conf config and check the environment set for the process with: sudo cat /proc/2586/environ VIR_BRIDGE_NAME=virbr0 After killing the re

[Touch-packages] [Bug 1326536] Re: libvirt's dnsmasq setup will read /etc/hosts on the host, resulting in odd resolution behaviour on the VM

Never mind, I took some time to patch libvirt to see if it would have any effect. Appears to only apply to the records dnsmasq receives the DNS queries it makes, doesn't ignore any addresses read in from /etc/hosts. -- You received this bug notification because you are a member of Ubuntu Touch se

[Touch-packages] [Bug 1326536] Re: libvirt's dnsmasq setup will read /etc/hosts on the host, resulting in odd resolution behaviour on the VM

Perhaps a change could be added to ignore 127.0.0.1 and 127.0.1.1 addresses returned by default? Dnsmasq supports such an option, though it would need to be added to libvirt as it regerates the dnsmasq conf file used each time a network is started. Add following by default to dnsmasq.conf genera
