Changed in v4:
- rebased on top of the latest chardev changes
- remarks applied
- patch 1 fixed so it works with alias names
========
Changed in v3:
- minor remarks to patch 1 applied
- patch 3: avoid using bottom-half, handle syncronously
As mentioned, it gets thing complicated and is only a problem for
a monitor-connected chardev hotswap and that is not supported for now
- tests added (patches 6-9)
========
This serie is a v2 of the February submit
http://lists.nongnu.org/archive/html/qemu-devel/2017-02/msg01989.html
The interface is changed as requested and the changes are slightly reworked
and split into separate patches.
========
The patchset adds support of the character device change without
a frontend device removal.
Yet isa-serial and virtio-serial frontends are supported.
The feature can be helpful for e.g. Windows debug allowing to
establish connection to a live VM from VM with WinDbg.
