When meeting request to write the cluster without copied flag,
allocate a new cluster and write original data with modification
to the new cluster. This also adds support for the writing operation
of the qcow2 compressed image. After testing, image file can pass
through qemu-img check.
Please
This is the more work base on my v1 patchset which is posted some months ago,
it can be found at:
https://lkml.org/lkml/2011/2/22/68
Change log:
- sort memslots base on its size and do the line search instead of binary
search base on gfn, it is from Avi's idea.
- in order to reduce cache

Device lock should be held when releasing a device, and specifically

The operation of getting dirty log is frequency When framebuffer-based
displays are used(for example, Xwindow), so, we introduce a mapping table
to speed up id_to_memslot()

Your question should have been sent to qemu-devel ML because the logic

Hi guys,
Today during the last 'sanity' qemu-kvm testing, we've noticed a
recurring problem: guest OS does not see the floppy, making the windows
installs time out. This problem has been extensively discussed on qemu
and qemu is fine here, problem is specific with qemu-kvm.

The Open Virtualization Alliance is going to be having a webinar on
