#2379 fixed Shared folders - unable to seek beyond 2GB => Fixed in SVN George Prekas
Description

I am using VirtualBox 2.0.2 on Windows XP SP2 running Linux 2.6.18 as a guest OS. When I create a file larger than 2GB I am unable to seek into it past the 2GB point. Using this command works as expected: dd if=/mnt/windows/testfile bs=1k skip=2097151 count=1

But using this command it takes a lot of time to read the record: dd if=/mnt/windows/testfile bs=1k skip=2097152 count=1

The reason is (as shown by strace) that the initial llseek fails so dd tries to read the whole file from the beginning in order to reach the requested record.

The reason is that the field s_maxbytes of super_block struct is not initialized by the vboxvfs module. I have attached a possible fix.

#2380 fixed VirtualBox 2.0.2 GUI hangs / stops responding to input myxiplx
Description

Over the past few days I've noticed that the VirtualBox virtual machine window will stop responding to input for several minutes, although the virtual machine can be seen to be running fine.

I can't find any bugs similar to this on the tracker, but it appears I'm not the only person noticing this as I found this post in the forums: http://forums.virtualbox.org/viewtopic.php?p=40763#40763

I'm noticing the problem at least once a day at the moment, but can't yet see any pattern as to when this happens.

#2381 fixed virtualbox 2.0.2 is unable to "reboot -f" an opensolaris snv_100 guest jkeil
Description

There's a new "fast reboot" feature in opensolaris build 100: http://www.opensolaris.org/os/community/on/flag-days/pages/2008092201/

Problem: virtualbox 2.0.2 is unable to "reboot -f" an opensolaris snv_100 guest (64-bit and 32-bit). The guest shuts down, but virtualbox 2.0.2 guest hangs while trying to start / reboot into the new kernel.

HW: AMD64 X2 cpu, AMD-V enabled in virtualbox. Host OS: SXCE build 96, bfu'ed to current opensolaris bits (2008-10-2)

The guest hangs in fb_swtch_src.s when the kernel switch page tables are installed.

http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/i86pc/ml/fb_swtch_src.s#209

usr/src/uts/i86pc/ml/fb_swtch_src.s:

   209          /*
   210           * Load top pagetable base address into cr3
   211           */
   212          movl    FI_PAGETABLE_PA(%esp), %eax
   213          movl    %eax, %cr3
   214
   215          movl    %cr0, %eax
   216          orl     $_CONST(CR0_PG | CR0_WP | CR0_AM), %eax
   217          andl    $_BITNOT(CR0_NW | CR0_CD), %eax
   218          movl    %eax, %cr0

Workaround: Boot Solaris guest with "-B disablePAE=true", and strip the PAE feature mask (0x200) from the kernel variable x86_feature.
