| #1335 | duplicate | Very low speed on outgoing traffic with NAT | ||
| Description |
Description The NAT mode guest interface is truely a great feature, but there are some optimization/scheduling problems on outbound traffic to remote hosts. I have tried this on several hosts (linux and windows) each with different hardware configurations, the result is the same - a throughput less than 500 kbyte/s (on windows hosts less than less than 100 kbyte/s). There is no problem when sending data from the guest to it's host. I have spent days debugging and profiling, but the problem is not a part of my expertees so at last I had to give up. I have communicated quite a lot with the vbox developers via IRC passing on debug and profiling information - they say the problem is due to low prioritized scheduling on the host side. Reproduce
Odd observations
My opinion I think there is a great potential in NAT with port forwarding, because it enables you (in conjunction with VBoxHeadless.exe) to distrubute a virtual machine and run it as a normal service (ie. Windows Service) the only thing missing is outgoing traffic speed :-) Best regards Jakob Simon-Gaarde btw: vmware's NAT has the same defect. So this could be a place where VirtualBox can offer a little more :-) |

| #1336 | fixed | VirtualBox crashes on Solaris host when using Share Folder on WinXP guest => Fixed in 1.6.4 | ||
| Description |
I've recompiled VirtualBox from Mar-15-2008 source trunk on Solaris Nevada build 82. If I add a share folder to my WinXP guest, VB crashes with the following stack (see next comment). It's 100% reproducible. I believe this is happening when WinXP tries to reconnect the network drive. |

| #1337 | fixed | Protocol error when attempting to connect to VBox VRDP using Microsoft's RDP client for Mac -> Fixed in a future version 1.6.6 | ||
| Description |
Running Windows XP guest system via VBoxVRDP on Fedora 7. VRDP is configured for "external" authentication. The Linux rdesktop command connects to the guest, no problems. When I attempt to connect to the guest system using the "Microsoft Remote Desktop connection Client for Mac Version 2.0.0 Beta 2 (071001)" it fails to connect. A protocol error is logged in the VBox guest's log against a packet that contains the userid and password being sent by the client. (Dummy "userid" and "password" used in the log entry below in place of my real userid/password.) The Mac client does successfully connect to other remote PCs.
