#6284 obsolete Openvpn disruption when active VM with bridged network Giovanni Toraldo (gionn)
Description

I have a Mac OSX 10.6.2 as host, and I use a Debian Lenny as guest for development purposes with ethernet bridging.

I often use vpn connections on Mac host, with tunnelblick (http://code.google.com/p/tunnelblick/). For the first time today, I noticed some strange behavior with a new vpn configuration, resulting in very poor nfs performances, going stall completely after few minutes.

Another (nice) problem I get, is with ssh through the same vpn:

scorp@antani-mac:~$ ssh -l libersoft 192.168.1.1
Last login: Wed Feb 24 18:02:36 2010 from vpn.libersoft.bncf.lan
libersoft@nfs-server:~$ exit
scorp@antani-mac:~$ ssh -l 123456789 192.168.1.1
123456789@192.168.1.1's password:
scorp@antani-mac:~$ ssh -l root 192.168.1.1
Read from socket failed: Operation timed out
scorp@antani-mac:~$ ssh -l 1234567 192.168.1.1
Read from socket failed: Operation timed out

With an username > 8 chars, ssh connects almost instantly, with an username <= 8 chars, the session seems to start, but some answer from remote server get lost or my packages never get transmitted (note the retransmissions on the tcpdump for login <= 8 chars).

My dmesg shows (a lot of):

in_delayed_cksum_offset: ip_len 49408 (193) doesn't match actual length 207
in_delayed_cksum_offset: ip_len 49408 (193) doesn't match actual length 207
in_delayed_cksum_offset: ip_len 49408 (193) doesn't match actual length 207

If I shutdown (or even pause) every guest VM using bridged networking, the problem disappears.

The only reason I can find in this particular vpn config, is that it use udp packets (In the past I always used tcp-based ones).

#6285 obsolete navigating menus of guest windows using keyboard doesn't work Soren Harward
Description

When I have a guest window in focus but the keyboard uncaptured, I cannot navigate the menu using the keyboard. For example, I should be able to hit <alt>+<M> and pull down the "Machine" menu, or hit <alt>+<D> and pull down the "Devices" menu. Neither of these work. I can activate actions within the menus, like hitting <host>+<n> to get session information. But I can't get to the menus themselves.

#6286 obsolete 2D Video Acceleration Mac OS X 10.6.2 Host Linux Guest Disabled Chris
Description

When you enable 3D Acceleration the non-optimal warning shows up when you enable the 2D Video Acceleration. You can't start 3D without the 2D Video Acceleration. VirtualBox shows that 3D is enabled and will crash at login on Ubuntu 9.10
