UI Frozen on pause

[nim]

It's quite annoying. I did 'yum update' in guest Fedora. There was much disk activities while yum was installing updates.

I selected Pause from File menu and the UI froze that turned to a all-white window.

And it seemed the guest os was dead too because I saw no disk activities then.

Is there a VBox.log file from such a session available?

[nim]

Note - I have encountered about 5-8 crashes and frozen condition for the last one year of using VirtualBox.

That's not bad.

But compared to commercial VMware and Microsoft Virtual PC, 5 times is bad - far from commercial quality.

BTW, I had 0 crashes on VMware and less than 3 crashes on VPC, for a period of more than 3 years.

Yes, but complaining does not help us identifying the bug. I still don't see the information I requested.

[nim]

After I aborted the session, restarted and did 'yum update', I want to save the session. But the window froze again, completely unexpected because there was little activities inside the guest os.

[frank]

I still would like to see the VBox.log file.

[nim]

Get a frozen UI again.

Last line of log: 00:37:27.235 Changing the VM state from 'RUNNING' to 'SUSPENDING'.

In that case the guest most likely entered an ACPI sleep state. Disabling the guest power management will fix this issue. You can also prevent this behavior by doing the following:

VBoxManage setextradata VM_NAME \
  VBoxInternal/Devices/acpi/0/Config/ PowerS1Enabled 0

VBoxManage setextradata VM_NAME \
  VBoxInternal/Devices/acpi/0/Config/ PowerS4Enabled 0

The was a change in behavior with VBox 4.0.0 which will be reverted in the next maintenance release.

The old 3.2.12 behavior should be back with VBox 4.0.4.
