| #13156 | fixed | 'NAT Network' cannot send big files | ||
| Description |
It seems 'NAT network' does not implement flow control. From the attached network trace files one can observe that when flow control is needed, the 'NAT Network' adapter stops working and sends a RST to both ends of the tcp connection. My setup for demonstrating the problem is as follows:
Then the following command will show the problem in the 2 traces: $ dd if=/dev/zero bs=9820 count=1 | nc 192.168.178.25 9
This will mostly fail,
Using another adapter type does not make a difference. The 2 .pcapng files contain the network traces of the following commands: $ dd if=/dev/zero bs=9820 count=1 | nc 192.168.178.25 9 && echo OK 1+0 records in 1+0 records out 9820 bytes (9,8 kB) copied, 0,000322761 s, 30,4 MB/s OK $ dd if=/dev/zero bs=9800 count=1 | nc 192.168.178.25 9 && echo OK 1+0 records in 1+0 records out 9800 bytes (9,8 kB) copied, 0,000111585 s, 87,8 MB/s OK $ dd if=/dev/zero bs=9900 count=1 | nc 192.168.178.25 9 && echo OK 1+0 records in 1+0 records out 9900 bytes (9,9 kB) copied, 0,031919 s, 310 kB/s OK $ dd if=/dev/zero bs=99000 count=1 | nc 192.168.178.25 9 && echo OK 1+0 records in 1+0 records out 99000 bytes (99 kB) copied, 0,0124187 s, 8,0 MB/s OK $ Only the second command does not end with RST message in the .pcapng file. Of course, the workaround for this problem is to use the good old 'NAT' adapter... |

| Description |
A strange thing is that when I open Virtualbox, that the 'Oracele Virtualbox Manager' is appearing on every separate Desktop of my MacBook Pro. That was not the case before... Thank you for looking at this matter Gr Ett |

| #17748 | worksforme | 'Save State' shortcut key doesn't work | ||
| Description |
I wanted to be able to quickly close the guest window, so I created a shortcut key to do a 'Save State'. It didn't work. To to what I did, which is very easy, on the main VirtualBox window, go to File > Preferences > Input, then on the right side select the Virtual Machine tab and scroll down to the entry 'Save State'. By default it's blank. Enter a new combination, such as Host key + B (this one isn't already used up). Now launch any VM and press Host + B. It should do a 'Save State', it does nothing for me. I've tested assigning Host + B to other functions, such as the 'About VirtualBox...' entry, and it works, when I press Host + B the About window pops up, so that's not the problem. I've tested assigning Host + other key combos, doesn't work. I've tested assigning Host + B to 'Save State' on the VirtualBox Manager tab (instead of the Virtual Machine tab as explained above). Then I launched a VM, went back to the VirtualBox main window (Oracle VM VirtualBox Manager) and pressed Host + B, it worked perfectly. It should be clarified that in the case of the VirtualBox Manager tab the default entry for 'Save State' is Host + V, which also works perfectly. |
