#6311 obsolete OpenSolaris guest boot failure "int 15h function AX=ec00, BX=0003" Peter Dunlap
Description

I recently upgraded my system with a new motherboard (DFI LanParty X48) and Intel Core 2 Q9400 processor. Host operating system is OpenSolaris build 133. Prior to the upgrade I had three guest OSes that were working fine: OpenSolaris build 132, Windows XP and Ubuntu. After the upgrade the OpenSolaris guest will no longer boot but the Windows XP and Ubuntu guests still work fine. I also tried booting an OpenSolaris live CD image which also failed. In all cases the guest appears to hang immediately after the OS is selected at the grub menu. It never actually gets to the point where it prints the Solaris banner.

I'm running VirtualBox 3.1.4 which was freshly installed from the "extra" repository after the hardware upgrade.

According to the log it looks like the last thing that happens is always this unsupported BIOS function:

00:02:33.031 Guest Log: BIOS: * int 15h function AX=ec00, BX=0003 not yet supported!

The Solaris GRUB boot loader does use that function which would explain why it doesn't actually appear to load the Solaris kernel:

http://src.opensolaris.org/source/xref/ ... asm.S#2659

But if that is really the problem I don't understand how the guest ever worked. I will attach the logfile and the output from "VBoxManage showvminfo" for the guest.

#6317 obsolete host memory low etrusko
Description

Host system Windows XP Pro SP 3 32 bit 2GB RAM DDR2 1066 HDD free space 17GB on C:/

Guest Ubuntu 9.10 32 bit

When I try to install Ubuntu 9.10 from cd-live I end up with the message "host memory low". I have tried different amount of memory ,from the suggested 384MB up to the limit with no positive result,i.e. I have not been able to run any VM.

#6318 obsolete Monotonic counter as seen from guest is not monotonic Samuel Tardieu
Description

The attached program, which uses the Linux kernel monotonic counter, shows that the counter is not monotonic in a 32 or 64 bits Linux host, at least when the guest is a 64 bits Linux.

Several programs, such as the Ada runtime or the Factor programming language, depend on the fact that the monotonic counter is indeed monotonic.

Tested with:

  • Host: Arch Linux 64 bits 2.6.32
  • Guest: Arch Linux 32 bits or 64 bits 2.6.32

In the guest, compile and run the test program:

% gcc -O2 -o t t.c -lrt % ./t

After a few seconds at most, the program will exit with an error message, proof of the problem. If it doesn't, then everything is fine (this happens when executed outside of VirtualBox for example).
