AFAIK this is default Windows2008 behaviour in case S3 is supported by
the platform. But KVM supports S3 for Windows2008 guests only with QXL
display, so this raises the question: what is qemu command line on
the machine that it happens to and on the host where it does not happen.

That does look like S3 suspend. Can you run "info status" command on
qemu monitor when it happens?
