savestate order matters for multiple headless VMs

Description

I was able to replicate this issue on two machines.

Pre-condition: You have N > 1 VMs running headless mode

Test: Run controlvm savestate on all of them, one by one

Result: If the first VM that you started is savestate'd before the others, the other savestate attempts will fail. The system will report the other VMs as having 'aborted,' yet they continue to function normally. After this point none of the controlvm functions for these vms will work.

My testing has revealed that if the VMs are NOT started with VBoxHeadless, but, instead, started with the GUI, this behavior is not encountered. Note below:

In the above scenario I started the VMs in sequential order. I was able to stop them in sequential order using controlvm.

The following scenario shows what happens when the VMs are running headless:

During the "stop" script, I had four rdp sessions open to each of the VMs. Only the first session actually ended. The remaining three sessions were active and responsive. The last step illustrates how the controlvm fails to work after everything. Note that vbox reports the others as having 'aborted.'

Further testing showed that as long as the first VM started is the last one savestate'd the others would savestate successfully.

comment:1 Changed 5 years ago by frank

I save some strange problem when starting VMs with VBoxHeadless and doing savestate with VBox 2.1.4. I didn't saw this with the current trunk. Could you check with VirtualBox 2.2.0 Beta 2?
