*new user* trouble with Windows 7 guest

[J.L.L.]

Hello,
I am quite inexperienced with this, so my apologies before hand. But I receive the following error message when I try to turn up the display video memory past 100mb on my system. I have the most recent guest additions installed.

Failed to open a session for the virtual machine Windows 7.

Failed to map a memory object. (VERR_MAP_FAILED).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: Console
Interface: IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb}

Can anyone help? I imagine I might need to provide more info which I am happy to do.

Thanks,
JD Lancaster

It is attached. Hope that is what you need.

Does the guest boot up in you select a lower amount of Video memory?
What happens if you set the RAM for the guest at 1024MB and the video at 128MB?

It starts fine with the settings you suggested. Is there a way to get more video acceleration though?

Thanks

The virtual video memory is actually taken from the system RAM. If you want more you will need to close some of the other applications on the host that you are running. Look at the log file at the top for available memory and try to make sure that you have enough to run the guest and have some left over.

Hi there,

Thanks for all the help. So is there a way to enable the guest to use the video hardware on my computer?

Virtual machines do not use physical hardware.
