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. Further information: http://forums.virtualbox.org/viewtopic.php?f=1&t=16068 My testing has revealed that if the VMs are NOT started with VBoxHeadless, but, instead, started with the GUI, this behavior is not encountered.

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. {{{ kyle@anarix:~/vm$ VBoxManage list vms | grep -E '^(Name|UUID|State)' Name: UBUNTU1 UUID: c13c4a38-4e1d-453a-b0d6-89545c95a83c State: running (since 2009-04-05T02:07:27.089000000) Name: UBUNTU2 UUID: d4524a2a-1e00-4d33-9d54-9f5d1ab8d4f5 State: running (since 2009-04-05T02:07:29.035000000) Name: UBUNTU3 UUID: 07103247-31fb-42f0-bb2e-6fa919e88fc4 State: running (since 2009-04-05T02:07:32.038000000) Name: UBUNTU4 UUID: eec292b7-242f-4022-ad8c-bebc695d02a6 State: running (since 2009-04-05T02:07:36.107000000) kyle@anarix:~/vm$ ./stop-all.sh + for x in 2 3 4 1 + sleep 2 + VBoxManage -nologo controlvm UBUNTU2 savestate 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% + for x in 2 3 4 1 + sleep 3 + VBoxManage -nologo controlvm UBUNTU3 savestate 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% + for x in 2 3 4 1 + sleep 4 + VBoxManage -nologo controlvm UBUNTU4 savestate 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% + for x in 2 3 4 1 + sleep 1 + VBoxManage -nologo controlvm UBUNTU1 savestate 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% }}} Here's what happen when the first one started doesn't come last: {{{ kyle@anarix:~/vm$ ./start-all.sh + for x in 1 2 3 4 + sleep 1 + screen -S UBUNTU1 -d -m VBoxHeadless -s UBUNTU1 -p 10001 + for x in 1 2 3 4 + sleep 2 + screen -S UBUNTU2 -d -m VBoxHeadless -s UBUNTU2 -p 10002 + for x in 1 2 3 4 + sleep 3 + screen -S UBUNTU3 -d -m VBoxHeadless -s UBUNTU3 -p 10003 + for x in 1 2 3 4 + sleep 4 + screen -S UBUNTU4 -d -m VBoxHeadless -s UBUNTU4 -p 10004 kyle@anarix:~/vm$ vim stop-all.sh kyle@anarix:~/vm$ ./stop-all.sh + for x in 2 3 1 4 + sleep 2 + VBoxManage -nologo controlvm UBUNTU2 savestate 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% + for x in 2 3 1 4 + sleep 3 + VBoxManage -nologo controlvm UBUNTU3 savestate 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% + for x in 2 3 1 4 + sleep 1 + VBoxManage -nologo controlvm UBUNTU1 savestate 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% + for x in 2 3 1 4 + sleep 4 + VBoxManage -nologo controlvm UBUNTU4 savestate [!] FAILED calling a->virtualBox->OpenExistingSession (a->session, uuid) at line 2784!
