| #2256 | duplicate | Accessing host documents via vboxsvr share very slow | ||
| Description |
Hi, This problem first reared its head after 1.5.6 Yes, I should have logged a bug back then but I had a work-around which wasn't too much pain. I think it's time to fix this issue. :)
Problem When using the `vboxsvr' share to Open and Save files, especially, Office files, it's very slow compared to using a regular Windows share from the Guest to the Host.
Environment
Guest O/S Windows X/P; Service Pack 3. Office 2007.
Host O/S openSUSE 11.0 - 2.6.25.16-0.1-pae Test Case
o Create a new PowerPoint file and place it on the Host - ensure it is also accessible to the Guest via the Network Neighborhood Browse function
Additional Forensics
I downloaded and installed WinDump (similar to tcpdump) and noted when the I can collect more data if necessary. Just let me know. |

| #2257 | invalid | Cannot overwrite files in shared folders | ||
| Description |
Windows XP SP2 guest with Guest Additions 2.0.2r36486, Ubuntu 8.04 host. If I try to copy a file to a shared folder and it already exists there, and I click "Yes" in the Confirm File Replace dialog, I get an error dialog titled "Error Copying File or Folder" that says "Cannot copy <filename here>: The parameter is incorrect." After that, the file to be overwritten is gone. However, I am able to open, modify, and save files in the shared folder (usually) without errors. In what may be a symptom of the same bug, if I use shell redirection to overwrite a file in a shared folder, the old file is not truncated properly. Assuming X: is the shared folder drive, at the command prompt: x: echo asdf123456789 > trunc.txt more trunc.txt
echo qwer > trunc.txt more trunc.txt
The same thing happens when I overwrite a file using a Python script: if the new version is shorter, the tail of the old one remains. |

| #2258 | fixed | Solaris 10u5 guest hangs and consumes 100% CPU | ||
| Description |
Running Virtualbox 2.0.2 on a Sun Ultra 24 running Ubuntu 8.04 (64bit) and I am finding stability to be a real problem when Intel VT-x is enabled which in turn allows me to run Solaris 10u5 x86 in 64-bit mode. Running with VT-x disabled (same guest no running in 32-bit mode) is however stable. After a period of time (30minutes+ depends on activity on the guest itself) when VT-x is enabled the Solaris 10u5 (64-bit) VirtualBox process will become non-responsive (hang) and CPU usage will shoot up to 100%. The spinning thread is looping in the following call: (gdb) where #0 0x00007f727cbab3c7 in ioctl () from /lib/libc.so.6 #1 0x00007f727c414adf in ??

Nothing has helped so far. This issue appears to be triggered by load within the guest itself. For example I had to re-attempt the installation of Sun Communication Suite 5 three times before it would complete without the VM hanging half-way through the process. Installing the same product when the same OS is running in 32bit mode completes without a problem. I currently have 3 Solaris 10u5 guests running.
