NAT networking connection lost after making new snapshot => Fixed in 1.5.4

[Frans Pop]

NAT networking works perfectly until I make a snapshot. Immediately after that I get "temporary failure in name resolution" errors, i.e. that the system can no longer contact the DNS server. Attempts to connect using IP address fail with "no route to host". Retrying does not help.

If I revert to that same snapshot and restart the VM, the _first_ attempt to e.g. scp a file will mostly fail. However, a second attempt will succeed. After that, networking is completely reliable again.

This issue is 100% reproducible.

Context: Using a Debian Installer CD image to install a new system Host system: Pentium D SMP x86_64 system running Linux 2.6.23 VM: VirtualBox 1.5.2 running 2.6.22 kernel

Thank you very much for this report. Fixed in SVN (after next sync to public) and for 1.5.4.
