Restoring snapshots causes vboxsvc crash #535

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Restoring a snapshot crashes vboxsvc. Requires a restart of vboxwebsrv.

What steps will reproduce the problem?
1. Shut down a virtual machine, take a snapshot
2. Boot up virtual machine, make some changes
3. Shut down virtual machine, attempt to restore to snapshot

What is the expected output? What do you see instead?
I expect the virtual machine to be quickly restored as it works within 
VirtualBox. However, the restore starts and the progress bar goes to 50% and 
then hangs. Then crashes.  It appears that it crashes VBoxsvc.exe on the host 
which takes down all running virtual machines.

What version of phpVirtualBox, VirtualBox, and PHP are you using? On what 
operating system?
Running VirtualBox 4.12
phpvirtualbox 4.1.7
Host Windows XP SP3
Guest Windows XP SP3
PHP version 5.3.8

Please provide any additional information below.
I have this issue with phpvirtualbox running on the same machine as the 
virtualbox host as well as running phpvirtual box on another PHP Apache server.

Can you try this same process via the VirtualBox gui and see if you get the 
same results? This sounds like some VirtualBox bug rather than something 
specific to phpVIrtualBox.

I have. Snapshots are restored and deleted within seconds in the virtualbox 
gui. But when done via phpvirtualbox they hang and crash vboxsvc on the host. 
Then you end up with two child snapshots. One big one (the original) and one 
small one (then new current state). I then have to manually stop/start 
vboxwebsrv and delete the old big snapshot via the Media Manager. I guess I'm 
the only one seeing this?

I have the same problem. Also running Vbox 4.1.12 and phpvirtualbox 4.1.7. Host 
is CentOS 5.8 same guest. Restoring with VboxManage snapshot uuid restore uuid 
works as expected.

Updating.  
The problem seems to occur with Maxthon browser in our case.  Chrome and 
Firefox work fine.  Maxthon causes all virtual guests to shut down and 
vboxwebsrv to restart.

Does this happen with virtualbox 4.1.20?

This no longer appears to a problem for me with 4.1.20.
