#12737 fixed Cannot restore machine state for Win7 guest when using 3D acceleration 3vi1J
Description

I've had a Win7 guest VM that I'm running under a Linux host (Ubuntu). Saving and restoring the guest machine state for this VM worked fine in 4.2, but has not worked since the first 4.3 release, even though I am working with brand new 4.3 save states.

I can start the VM from scratch (no saved session) and it will run fine. I can save the session/state, and it exits normally. But, when I try to restore a saved session, "Restoring Virtual Machine" halts at around 93% and I immediately get a VirtualBox popup that says:


Failed to open a session for the virtual machine Win7.

No error info.

Result Code: NS_ERROR_CALL_FAILED (0x800706BE) Component: ProgressProxy Interface: IProgress {c20238e4-3221-4d3f-8891-81ce92d9f913}


At that point, the machine shows as "Aborted", and restarting it reboots it from scratch.

Now for the interesting part: If I disable 3D acceleration in the VirtualBox display options for the machine, I can save and restore the state with no problem. When enabled, 3D acceleration works fine (the machine does have the latest guest utils/drivers installed), and I was using it when I was save/restoring under 4.2 with no issue.

I'm not sure why having 3D acceleration makes any difference. I've tried restoring the machine both with my native HD4000 graphics and my nvidia 670MX chipset (via bumblebee) and get the same results. As I said, 3D acceleration works fine within the guest (as do my many other native 3D apps).

I am attaching the log. Please let me know any other info you require to help troubleshoot this persistent issue. I've looked around the forums/bugs, but have been unable to locate someone with this specific problem.

#4268 fixed Add HostIP option for NAT port forwarding [patch] 403
Description

Currently only forwarding *:<port> to guest is possible. The attached patch makes it possible to forward <ip>:<port>. It adds a HostIP option which defaults to 0.0.0.0. The solution for tcp_subr.c is still not perfect and can be improved if needed.

#4269 fixed Fix createrawvmdk on FreeBSD host [patch] 403
Description

The attached patch makes VBoxManage internalcommands createrawvmdk work on a FreeBSD host.
