Host networking in 2.1.0 may cause kernel panic

[chronoboy]

Depending on which distro you have and which interface your host networking is attached to, you may experience a kernel panic and keyboard issues on your host.

I have submitted a very detailed explaination and how to reproduce this in my new ticket. There are some tickets relating to either host networking or host keyboard failure. Both of these issues are related to a kernel panic which is in turn related to the new network filter kernel module.

The ticket has a dump of my kern.log, where it shows the exact message from the kernel panic which is normally displayed on the system console. Please review this ticket careful and comment if either you experience a keyboard or host networking related issue. Check your /var/log/kern.log as a root user and verify if the vboxnetflt module is causing the issue. I so, enter in a ticket comment stating your kernel version and distro of choice.

I would really like this issue resolved as soon as possible, as host networking is very important for many testing and production applications.

Thanks but you shouldn't assume that the developers visit the forum. This content should have gone in your ticket. Also for future reference don't put your log inline but add it as an attachment.

Edit: sorry missed a couple of letter which effect the post!!

Sorry Terry, was in a hurry and did not have time to copy the portion and paste it into a new file to attach.

I updated the ticket with further research on the issue:

The kernel panic happens when the guest attempts to communicate using the HostIF. For example, a DHCP query would cause it to happen during guest boot if the guest is configured for DHCP. Setting the guest to a static IP address will still cause a kernel panic, if a program in the guest attempts to communicate using the HostIF. This occurs on any host interface used, even the TUN device. This makes it difficult for a host and a guest to correct communicate with each other using HostIF.
