DNS resolution uses external system #11

Closed robholland closed 8 years ago

Because dhyve uses 8.8.8.8 for DNS the VM is unable to resolve DNS entries that the host can via VPN. Please offer a way to use the host for DNS resolution.

yeah using 8.8.8.8 was actually to mitigate an issue where occasionally dns didn't work in the vm, but i knew it wasn't the ideal solution. i'll try to figure out something more appropriate

Removing the 8.8.8.8 option from /etc/resolv.conf and leaving just the eth0 line on the VM worked fine for me, I can resolve things via the VPN.

Not sure if this is completely related, but I seem to be running into a DNS issue when trying to install Debian packages. If I ssh to the box I ping the sources successfully. Output below.
