#2548 fixed Saved state is discarded after VERR_NO_MEMORY Konstantin Vlasov
Description

Host OS: WinXP SP3 Guest OS: any

I tried to load a VM which was in saved state, but there was not enough memory on my host machine (many programs loaded), so I got VERR_NO_MEMORY. After that the saved state of this VM silently disappeared: in VB Manager it was shown in "Powered Off" state, and when I tried to open it again, it started loading from scratch, as if I discarded the saved state (which of course I did not). Log file of this VM is attached.

#2549 fixed Guru meditation (VERR_VMX_UNEXPECTED_INTERRUPTION_EXIT_CODE) when executing program Pim Pronk
Description

I am using VB 2.0.4 on Ubuntu 8.10 where I have a WinXP guest. In XP I have installed the program VCDS from Ross-tech (http://www.ross-tech.com/). This software is used for diagnostics on VW cars. Installation doesnot require a license key. The software comes with an usb dongle to connect your laptop with your car and the dongle also contains the license key for the software.

When I start this software in WinXP I receive a virtualbox critical error, the status of my guest is Stuck and the Guru went into meditation. This happens both when the dongle is connected and disconnected.

See attached files & screenshot.

#2550 fixed Undefined symbol in vboxvfs in x86_64 guest => Fixed in SVN sandbox
Description

I tried to use shared folders in opensuse 64 11.0 guest but vboxvfs fails to load even though the compile process claims to be successful:

VirtualBox 2.0.4 Guest Additions installation
Building the VirtualBox Guest Additions kernel module...
Building the shared folder support kernel module...
Installing the VirtualBox Guest Additions...

Successfully installed the VirtualBox Guest Additions.
You must restart your guest system in order to complete the installation.

modprobe says:

opensuse11-64:/tmp/install # modprobe vboxvfs
FATAL: Error inserting vboxvfs (/lib/modules/2.6.25.18-0.2-default/misc/vboxvfs.ko): Unknown symbol in module, or unknown parameter (see dmesg)

dmesg says:

opensuse11-64:/tmp/install # dmesg|tail -n 3
SFW2-INext-DROP-DEFLT IN=eth0 OUT= MAC= SRC=10.0.2.15 DST=224.0.0.251 LEN=64 TOS=0x00 PREC=0x00 TTL=255 ID=0 DF PROTO=UDP SPT=5353 DPT=5353 LEN=44
vboxvfs: disagrees about version of symbol RTSpinlockCreate
vboxvfs: Unknown symbol RTSpinlockCreate

in /tmp/vboxadd-Module.symvers there is one strange line:

0x00000000      RTSpinlockCreate        /tmp/vbox.8/vboxadd     EXPORT_SYMBOL

all other lines do have an address instead of 0x00. If I delete this line and recompile only vboxvfs with "/usr/src/vboxvfs-2.0.4/build_in_tmp --use-module-symvers /tmp/vboxadd-Module.symvers --no-print-directory install" the resulting module loads fine and shared folders seem to work:

opensuse11-64:/usr/src/vboxvfs-2.0.4 # modprobe vboxvfs; lsmod|grep vbox
vboxvfs                58792  0
vboxadd                89312  5 vboxvfs

However this is only an ugly workaround, I do not realy know if this breaks something and I suspect this error to occur on every newer 64 Bit distribution (it fails with same symptom and error code on Ubuntu 8.10).
I tried to reproduce this error with opensuse 11.0 32 Bit but there aren't any RTSpinlock* Symbols exported - maybe they also shouldn't be exported on 64 Bit?

Environment:
Host: opensuse 11.0 64 Bit
Guest: opensuse 11.0 64 Bit or Ubuntu 8.10 64 Bit
