9995	Taking snapshot freezes running guest OS	Chris Kukuchka		"Using VirtualBox 4.1.6r74727 on RedHat Enterprise Server release 5.7, when I ""take"" a snapshot on a running guest OS, it the guest OS gets permanently frozen.  To resume, I must poweroff the VM and start it fresh.

The guest OSes are RHEL 5.7 and Windows Server 2K3.

The version of VirtualBox I am using was downloaded from www.virtualbox.org.  This is the version information reported by rpm:

VirtualBox-4.1-4.1.6_74727_rhel5-1

The host OS kernel info as reported by ""uname -a"" is this:

Linux seqvhs 2.6.18-238.el5 #1 SMP Sun Dec 19 14:22:44 EST 2010 x86_64 x86_64 x86_64 GNU/Linux

I have tried ""vboxmanage controlvm {name} resume"" and it does not restart the guest OS.

Attached are the VBox.log files for the two guest VMs.

From what I can see, taking the snapshot on the RHEL machine results in a ""state"" of running.  However, the guest OS itself is not responding.  The W2K3 guest acts differently in that it gets stuck in a ""Guru Meditation"" state.
