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. > what could be worth noting is that CPU usage of qemu process drops > to zero when this happens, otherwise windows guests eat quite a lot > of CPU time even when "idle". Maybe I should somehow check what the > process is doing? (how?) That does look like S3 suspend. Can you run "info status" command on qemu monitor when it happens? -- Gleb.
