[Qemu-devel] [PATCH 6/8] virtio-serial: Add a 'virtserialport' device for generic serial port support |
Date: |
Wed, 20 Jan 2010 00:36:56 +0530 |
This commit adds a simple chardev-based serial port. Any data the guest
sends is forwarded to the chardev and vice-versa.
Sample uses for such a device can be obtaining info from the guest like
the file systems used, apps installed, etc. for offline usage and
logged-in users, clipboard copy-paste, etc. for online usage.
