Hi everyone, I'm not clear about the principle of the vm snapshot based on qemu-dm, so the following below maybe a joke. Sorry for that... register_savevm() included in ioemu-qemu-xen/hw/*.c covers various kinds of hardware in order to save the state of current running vm. In this way, the file saved by the cmd of 'xm save domain snapshot.save' is of large size and the operation costs much time. Is there anyelse way to qucikly create a snaps...

The existing stdvga driver from xen-unstable tools/ioemu/hw/vga* does not save the emulated VGA memory contents. The symptoms include video malfunction after restore, including black screen (which can often be fixed by asking the guest to redraw) but also missing font setup etc. The attached patch fixes this by saving the entire VGA memory buffer, just like the Xen ioemu Cirrus emulator does.

Hello all, Here is a new iteration of the patch series that implements a transport for guest and host communications. The code has been updated to reuse the virtio-console device instead of creating a new virtio-serial device. I've tested for compatibility (old qemu & new kernel, new qemu & old kernel, new qemu & new kernel) and it all works fine. There are a few items on my
