#12140 obsolete Change default behavior when host's name server is 127.0.0.0/8 Bartzy
Description

Hi,

The current behavior when the host's name server in resolv.conf is in the 127.0.0.0/8 (Ubuntu special case with dnsmasq), is to enable the host resolver, which breaks any DNS query other than A (PTR, MX, etc).

See: https://www.virtualbox.org/browser/vbox/trunk/src/VBox/Devices/Network/slirp/slirp_dns.c#L283

A better solution would be to enable DNS proxy, which will proxy all DNS queries to the host's name server.

Is there any reason not to use the DNS proxy instead of the Host resolver in this case?

Thank you, Bar.

#761 fixed Absurd benchmark results in Guestsystems Maik Barz
Description

Host: Ubuntu 7.04 server Guest1: Ubuntu 6.06 lts server Guest2: Ubuntu 6.06 lts server

Running tests like bonnie++ and nbench-2.2.2 return absurd results: Guest systems acquire 10times better results than its host. The tests are run seperately, not parallel on host and guest!

Bonnie++ is a io/hdd benchmark and nbench is a Bytemark CPU benchmark.

Virtualbox Version 1.5.0

The same tests on XEN and VMware server return "correct" results, so that it does not seem to be an error at those benchmark programs
