Hi Srini8987,

Could you please attach complete VBox.log?

[Srini8987]

Hi, I have attached the file. Thanks.

Hi Srini8987,

Thank you for the log. Quickly looking into it, I see that you are attempting to copy a bitmap from Windows host to Linux guest. Currently, buffer reserved for this on Linux guest side is of size of 4K. And error message is telling that this buffer is not big enough to fit it. How big bitmap is?

UPDATE: 4K buffer is reserved on the guest side for initial clipboard transfer (host -> guest). If this buffer is not big enough, host will report required buffer size to the guest and guest will re-attempt to get host clipboard with the bigger buffer size. This ticket describes a case when "re-attempt" behavior was broken. Fix will be a part of the next 7.0.2 release.

Hi,

I am just copying like 100 lines of text from text editor. Currently I can copy only 10 lines max. From 11th line onwards, i see this error.

I am not copying any images or screenshots to and from VM now.

Thank you. Srini.

Hi Srini,

My bad, you are correct. It is text. What editor do you use on a Windows host side?

Could you please also analyze your host clipboard content with, for example, ​https://freeclipboardviewer.com/ tool and tell what is the host clipboard data size for Unicode text and possibly attach its content in HEX format?
