Hi, guys.
I'm looking for the hot-plug/unplug features of virtio-9p device recently,
and found there's a lack of support.
I am wondering why ? Is there a reason. Actually, I write a qmp command to
support fsdev_add, then a device_add qmp will
successfully add a virtio-9p
Hi Greg,
Yes, it was nothing to do with the virtio-9p. I was writing at 4k Blocks
now I changed it to 1K Block. This works fine for me.
Thanks for your help.

The problem I guess is adding these task ids to the "tasks" file in cgroup

Hi All,
I am using virtio-9p for sharing the file between host and guest. To test
the shared file I do read/write options in the guest.To have controlled io,
I am using cgroup blkio.
While using cgroup I am facing two issues,Please find the issues below.

I don't really understand the "devices shared between the guest
Hi Greg,
Thanks for the reply.
Let me put it this way, virtio-blk-pci is used for block IO on the devices
shared between the guest and the host.
Here I want to share the file and have QoS between the guests. So I am
using the Virtio-9p-pci.
Basically I want to have QoS for virtio-9p-pci.

Hi All,
Is virtio-9p-pci device only supports the fsdev deices? I am trying to use
-drive option for applying QoS for block device using Virtio-9p-pci device,
but failing to create/add a device other than fsdev. Can you please help me

Hello,
I am a summer intern under the Outreachy program (returning to
software development after a long hiatus). I am developing a prototype
of a xen front/back end for a 9p file transport.
Since virtio is the most complete, and used, transport, I am using
that as a model.
I am enc
There is still the need to serialize the fid linked list.
I saw in the current code base that virtio-blk.c was using the old API to
serialize a linked list.
Does writing support for serializing linked list in vmstate worth it ?
Or is it better to keep the old API to serialize ?

Migration runs with the VM paused. It would be simplest to flush all
the requests before migrating, that's what the block layer does. (The
migration of requests we have in virtio-blk, scsi-disk etc
Thanks for the explanations I'll start working on the patchset.

It has to rewritten with the new model with respect to migration. Also
these is problem of how much time does it take to migrate the fid
information ?. We also need to ensure new 9p request are bloc

I am interested in working on 9p live migration.
I remember that you had some live migration related patches on github.
