#3141 obsolete Check nested paging capability properly. Ahmet Sayın
Description

i check nested paging setting and program can support checking and activing but in guest system, nested paging shows passive

#3146 obsolete Host cannot connect to guest using 2.1.2 host network interface Mike Sadd
Description

Just installed VirtualBox 2.1.2 Linux (64bit) on Ubuntu 8.10. Enabled the new host interface connection using the kernel module, with much easier set-up than 2.0.6.

Most connections work very well, in that the Guest can connect to all machines, and all other machines on the sub-net except the host can connect into the guest.

One issue is the connection from the host into the guest, similar to the issue in tickets #3017, #3056, #3080. Tried the patch mentioned there, but it appears to be applied already in 2.1.2 and in any case did not correct the behavior.

To illustrate issue, consider the result of tcdump while using nc to establish a tcp connection.

On the guest system (ip 192.168.0.14), executed:

nc -l 1234

On the host system (ip 192.168.0.17), executed:

nc 192.168.0.14 1234

No connection is established. The output of tcdump is:

# tcpdump -n -i eth1 port 1234
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 96 bytes

For comparison, if nc 192.168.0.14 is executed on a third host on the subnet, it works fine:

# tcpdump -n -i eth1 port 1234
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

One difference may be in the third line of the output.

For host -> guest:

For external ip->guest:
[...]  . ack 1 win 1460 <nop,nop,timestamp 34219648 527353>

#3157 obsolete WinVista Network drive fails reconnecting Harald Stuebinger
Description

This might be the same problem as already mentioned in tickets #22 and #376. There it is mentioned as fixed.

I observed it with the following system: Machine: Mac Mini Intel Core2Duo 1,83; Host: Mac OS X Leopard; Guest: Windows Vista x64 SP1; Virtualbox Version 2.1.2;

I connected a drive to virtualbox shared folders. When I open it in Windows explorer, the drive symbol is shown with a red cross. But when I select the drive I can browse in the folder structure without any problems. Also programs can be started.

I recently installed a old setup program "called Wise". I opened there the file choose dialog in this program and try to select the drive. However, I got the following error message: An error occured while reconnecting S: to \vboxsvr\development. Virtualbox Shared Folders: The request is not supported. This connection has not been supported. Seems that the old file choose dialog has a problem with mapped drives. Also, in the MS explorer, it shows the red cross (Not okay), but I am able to browse???
