[Spice-devel] windows guest file transfer -- am I using the correct howto?

[Marc-André Lureau]

Hi

Thank you for trying the folder sharing feature. I am running on f21
virt-manager, and I installed a fresh win7 x64, with spice-guest-tools
0.74. Then I ran spice-webdavd.msi, installation was successful,
however, the service was stopped immediately. I realized the channel
wasn't connected, however, the service starts fine with a linux guest.
It seems the virtio channel behaves differently on Linux (blocks on
read) and Windows (returns 0 immediately) when the channel is
disconnected. This makes the Windows service stop when the guest is
started without a client connected for example.

There is a missing channel connect() in various clients.
For ex, virt-manager needs:
       elif (type(channel) == SpiceClientGLib.WebdavChannel):
            channel.connect()

But instead of pushing this in each clients, we can also just decide
to do it by default in the spice widget, so I sent I patch for that.
In the meantime, you can run spicy, which does connect the webdav
channels. Once the channel is connected, I could run the service just
fine, and mount the drive and browse. Note: while playing with webdav
channel, I noticed several time some nasty crash. It looks like a
spicevmc issue, channel sasl_conn was overwritten, and this lead to
crashes. Unfortunately, valgrind didn't help, and I can't reproduce it
anymore. So hopefully, you can mount your shared folder successfully
too!
