#3680 fixed audio problem richard
Description

Hi,

I use VirtualBox for school on a LTSP server host (ubuntu 8.10). The Hypervisor optimizations of 2.2's version are effectively best :

I can run 2 VM who play video in Giga with 1,4Go of RAM (2.1 : the server take all the free memory and swap).

Well, I have some problems with the sound :

  • The sound is clear with SB16 but the micro didn't work
  • The sound is chopped with ICH AC97 but the micro seems worked

On the server or on a thin client.

#3682 fixed opensolaris guest using shared folders writes null padded file. Rand S. Huntzinger
Description

First - thanks for adding shared folders for Solaris clients. Unfortunately, I seem to have found a problem on it. First - the setup.

Host: Dell 1850 running SXCE build 111. The system stores all files on ZFS (including shared ones) Guest: OpenSolaris (Indiana) - also build 111. VirtualBox 2.2.0 (installed yesterday)

I have a shared folder mounted on the client and here's what happens when I attempt to write.

randy@indy:/vbox/Shared$ > written_by_guest randy@indy:/vbox/Shared$ ls -l total 3404056 -rw------- 1 randy sysadmin 56776 2009-04-09 14:00 VBox.log -rw-r--r-- 1 randy sysadmin 3485696384 2009-04-09 14:05 written_by_guest randy@indy:/vbox/Shared$ ls -ls total 3404056

56 -rw------- 1 randy sysadmin 56776 2009-04-09 14:00 VBox.log

3404001 -rw-r--r-- 1 randy sysadmin 3485696384 2009-04-09 14:05 written_by_guest randy@indy:/vbox/Shared$

As you can see, it appears to have written a very large null filled file when it should have written a zero length file. When viewed from the underlying host, it appears that the file is long but empty (just one big hole). Unfortunately, from within the guest the hole is read as a string of nulls (which takes a long time).

hobbit$ ls -ls total 113

112 -rw------- 1 randy sysadmin 56776 Apr 9 14:00 VBox.log

1 -rw-r--r-- 1 randy sysadmin 3485696384 Apr 9 14:05 written_by_guest

hobbit$

If we write text into the file, it appears to be padded with nulls at the end.

randy@indy:/vbox/Shared$ echo hi > test2 randy@indy:/vbox/Shared$ ls -l test2 -rw-r--r-- 1 randy sysadmin 3485688192 2009-04-09 14:10 test2 randy@indy:/vbox/Shared$ od -c test2 0000000 h i \n \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 0000020 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 * C randy@indy:/vbox/Shared$

This seems to only occur when the file is written from an OpenSolaris guest. The same operation from a Solaris 10 guest seems to work properly. Must be a SunOS 5.11 thing.

#3683 fixed Solaris guest does not boot on VBox2.2 on Vista 64 AMD Turion andrew
Description

Hardware: HP Pavilion dv9000 Host OS: Windows Vista Home Premium 64-bit VBox: 2.2 Guest OS: OpenSolaris or Solaris 10 U6

What happens: For OpenSolaris: the OS image 'panic' after selecting the default boot from boot manager. OS can never be loaded. This is regardless if you create the VM for 32 or 64 bit.

For Solaris 10: The OS installation program will run. But after installation, the reboot will lead to the same 'panic' state. Again, this is regardless you choose to create 32 or 64 bit VM.
