#10849 obsolete Changing VM names breaks snapshot path, Causes ProgressProxy error Era Scarecrow
Description

I'm not sure if it didn't work at all or if this is because the original (base) VM was running at the time. But here's the steps that took place.

Created new (base) VM Changed Drive to Multi-Attach (after setting the VM how I wanted it) Created new VM attached to first VM's hard drive (not cloned)

Once a snapshot/difference was generated, changing the VM of the second (attached) VM.

Results:

The Base VM (with the original hard drive image and redivided snapshopts) had all it's snapshot attachments pointing to their original directories. Example:

<HardDisk uuid="{xxx}" location="C:/Users/Era/VirtualBox VMs/Base/DirectVM.vdi" format="VDI" type="Normal">

<HardDisk uuid="{5xxx}" location="C:/Users/Era/VirtualBox VMs/newVM1/Snapshots/{5xxx}.vdi" format="VDI"/>

<HardDisk uuid="{7xxx}" location="C:/Users/Era/VirtualBox VMs/newVM2/Snapshots/{7xxx}.vdi" format="VDI"/>

</HardDisk>

In this case if newVM1 or newVM2 gets renamed, the base system didn't update the directory location to their new spot(s) since the directory changed. Fixing it manually is trivial in notepad++ but annoying.

#7192 obsolete Problems with (virtual) APM support Lars Erdmann
Description

host: Windows 7, guest: OS/2 (eCS 2.0):

seems that there is a shortcoming in the virtual APM support: when you want to want to transition eCS from "Full On" to "Off" you first need to transition to "APM enabled" before you can do the transition to "Off".
However, transitioning to "APM enabled" leads to OS/2 APM error code: "GIOERR_PowerBiosError" on invoking the corresponding IOCTL call.
IOCTL calls used in OS/2: transition from "Full On" to "APM enabled": cat IOCTL_POWER func POWER_SENDPOWEREVENT subID APMEVENT_EnableAPM (=3)
transition to "Off": cat IOCTL_POWER func POWER_SENDPOWEREVENT subID APMEVENT_SetPowerState (=6) , device id APMDEVID_AllDevices (=1) , pwrstate APMSTATE_Off (=3)

#5353 duplicate Very long file load/save times in Windows 7 guest through vboxsvr Eric Carroll
Description

A save of a powerpoint 1.5MB file using smb takes under 3 sec. Saving the same file through vboxsvr takes up to 3 minutes.

Similarly load times are very long. Loading the same 1.5 MB ppt through vboxsvr takes over 30s, while smb is less than 4 sec.

tcpdump of wire during the load and save shows significant netbios traffic attempting to resolve vboxsvr. It also shows DNS lookups of vboxsvr. I have added vboxsvr to the hosts file without success so far.

Provider Order shows Virtualbox Shared Folders first in the list.

Disabling "Client for Microsoft Networks" and "File & Printer Sharing" did not cause the netbios lookups to go away.

Significant repeats in the vb log file of the following were found:

00:20:33.024 SharedFolders host service: request to unmap folder handle 0
00:20:33.024 SharedFolders host service: unmap operation result VINF_SUCCESS.
00:20:37.990 SharedFolders host service: request to map folder Home
00:20:37.990 SharedFolders host service: map operation result VINF_SUCCESS.
00:20:37.990     Mapped to handle 0.

Upgrading to 3.0.10 resolved the "no more files" problem but did not resolve the performance issue.
