Multiple ports support for virtio_console; major number for dev
Hello, This is the patch that I have for adding support for multiple ports to virtio_console. It's pretty stable in my testing so far and the memory corruption that I had earlier has been resolved in linux-next so I'm proposing this for inclusion. This currently uses device major number 60 from the experimental range; Alan could you please reserve a new major number for virtio_console?

Multiple port support for virtio-console
Hello all, Here is a new iteration of the patch series that implements a transport for guest and host communications. 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 todo list but this works well. New since last send: - live migration support** - write path in the guest

Extending virtio_console to support multiple ports

OOPS in hvc / virtconsole
I'm running a Fedora distro kernel (3.13.7-200.fc20.x86_64) in kvm with these options: -chardev null,id=hvc0,signal=off -device virtio-serial-pci -device virtconsole,chardev=hvc0,name=virtme_console -append console=hvc0 console=ttyS0 -nographic (There are more, but these are the interesting ones, I think.) Note that virtio_console is modular, which might be a problem. It blows up like this: [ 0.443591] kernel tried to execute NX-protected page - exploit...

[PATCH] virtio: console: Enable call to hvc_remove() on console port remove
This call was disabled as hot-unplugging one virtconsole port led to another virtconsole port freezing. Upon testing it again, this now works, so enable it. In addition, a bug was found in qemu wherein removing a port of one type caused the guest output from another port to stop working. I doubt it was just this bug that caused it (since disabling th...

[PATCH] virtio_console: allocate inbufs in add_port() only if it is needed
...: Error allocating inbufs qemu error: virtio-serial-bus: Guest failure in adding port 2 for device \ virtio-serial0.0 This happens because buffers for the in_vq are allocated when the port is added but are not released when the port is unplugged. They are only released when virtconsole is removed (see a7a69ec0d8e4) To avoid the problem and to be symmetric, we could allocate all the buffers in init_vqs() as they are released in remove_vqs(), but it sounds like a waste of memory. Rather than that, this patch changes add_port() logic to only allocate the buffers if the in_vq has...
