7654,PowerOff and never again start (untill killall virtualbox_process),Jan Seidl,,"Hi, i have a similar problem as #7179...
I have virtualbox in cycle - restore snapshot, start VM, add sharedfolders, poweroff vm,...
and from time to time (hour, 3,.. - it is random) - virtualbox total ended (but in task manager running). I mean, examples in cmd:

first poweroff
{{{
c:\Program Files\Oracle\VirtualBox>VBoxManage.exe controlvm PE1 poweroff
Oracle VM VirtualBox Command Line Management Interface Version 3.2.10

ERROR: The machine 'PE1' does not have an open session

Context: ""OpenExistingSession(a->session, machineuuid)"" at line 90 of file VBoxManageControlVM.cpp
}}}

check state VM:
{{{
c:\Program Files\Oracle\VirtualBox>VBoxManage.exe showvminfo PE1

(...)
}}}
''(...) is unimportant information''[[BR]]

in every discusion I read, be solved is off PAE, but it`s same problem

ok, showvminfo say vm is poweroff, then:
{{{
c:\Program Files\Oracle\VirtualBox>VBoxManage.exe startvm PE1
Oracle VM VirtualBox Command Line Management Interface Version 3.2.10

Waiting for the VM to power on...
ERROR: The VM session was closed before any attempt to power it on
Details: code E_FAIL (0x80004005), component Machine, interface ISession, callee
}}}

and what is it? VM is power on...
