I recently set up my Amahi 7 using qemu-kvm instead of virtualbox (crash problems). Ever since I use qemu-kvm as the virtualization platform the server never crashed again . That solved another really strange problem appeared: some devices cannot connect to the internet because of DNS problems.
Situation in detail:
- Most devices work perfectly fine with the server. No issues at all. Those are: All other computers, low-end Samsung phones, iPhones.
Devices that do not work: Samsung 5s mini, Sony TV's
- DHCP IP lease works. Where testable ping works.
Connection to the internet fails when using URL's.
- Setting static IP on the "non-working" devices and appointing 220.127.116.11 as the designated DNS solves the problem.
