Spice remote-viewer client folder sharing (WebDav)

[jpmorrison]

Spice remote-viewer supports client folder sharing using WebDav (also used for clipboard).

• Spice client: needs to be built with phodav. Should be included by default in linux packages.
• The current Windows binaries from virtmanager-org do not have client folder sharing enabled. You need to build your own remote-viewer client or use an old version.
• Qemu: enable virtio serial for the guest and spiceport channel for the client
• Guest: needs to be running spice-webdavd (phodav)

Qemu

-device virtserialport,chardev=charchannel1,id=channel1,name=org.spice-space.webdav.0 \
-chardev spiceport,name=org.spice-space.webdav.0,id=charchannel1

Guest

• Linux/Windows - install guest tools drivers. Spice WebDAV daemon is needed for folder sharing.
• MacOS - can try building from https://gitlab.gnome.org/jpmorrison/phodav or the original.

MacOS

Update: spice-webdavd - working enough for testing when built with Homebrew. Builds with macports but unusable.

• The /destination/path mount point must exist
• sudo isn't needed if you own the mount point
• The -S option lets you kill/restart spice-webdavd easily. -v is optional

./spice-webdavd -p 9843 &

mount_webdav -S -v 'Client Folder'  http://localhost:9843  /destination/path

Debugging messages may help

G_MESSAGES_DEBUG=all ./spice-webdavd -p 9843

Macports spice-webdavd TL;DR; don't bother, use homebrew.

I am able to build and run phodav using macports for all the dependencies. Avahi seems to conflict so don't install it or disable it meson configure -D avahi=disabled

Once spice-webdavd is running, the client folder can be mounted from command line or Finder.

I have opened the client shared folder with Finder and even managed to copy a file but it stops working. There's no crash, no errors logged it just stops working. Wireshark shows it stops responding after a few PROPFINDS.

Homebrew:

brew install meson ninja glib libsoup icu4c
# make sure /usr/local/lib/pkgconfig/icu-uc.pc exists and fix if it's missing
cd /usr/local/lib/pkgconfig
ln -s ../../Cellar/icu4c/69.1/lib/pkgconfig/icu-uc.p

cd
git clone https://gitlab.gnome.org/jpmorrison/phodav
cd phodav
mkdir build
meson setup -D avahi=disabled build
ninja -C build

This builds with clang if you have Xcode/command line tools. Seems to run better if you install and build gcc. Xcode installs 'gcc' that calls clang by default.

Works better compiled with GCC

git clone https://gitlab.gnome.org/jpmorrison/phodav
cd phodav
mkdir build
CC=gcc-11 meson setup -D avahi=disabled build
ninja -C build

@jpmorrison I tried to follow your directions but alway get an error: meson.build:37:0: ERROR: Dependency "libsoup-2.4" not found, tried pkgconfig, framework and cmake even after "brew install libsoup@2". Do I need a kind of "dev" version? I just started my first steps on macOS and brew Thanks in advance

[jpmorrison]

I installed libsoup but it shows I have 2.7.4.1

Do you have pkg-config?

brew info libsoup

Thanks for the prompt reply. As mentioned "brew install libsoup" installed libsoup v3

brew info libsoup

I also installed libsoup@2

==> Caveats
libsoup@2 is keg-only, which means it was not symlinked into /opt/homebrew,
because this is an alternate version of another formula.

For compilers to find libsoup@2 you may need to set:
  export LDFLAGS="-L/opt/homebrew/opt/libsoup@2/lib"
  export CPPFLAGS="-I/opt/homebrew/opt/libsoup@2/include"

For pkg-config to find libsoup@2 you may need to set:
  export PKG_CONFIG_PATH="/opt/homebrew/opt/libsoup@2/lib/pkgconfig"

I guess I have to use the above "export" statements. I wasn't aware that "brew info" gives such hints. I will try and let you know. Or dead you have any other advice / hint.

[Tom9876]

Here my failed approach:

➜  phodav git:(master) export LDFLAGS="-L/opt/homebrew/opt/libsoup@2/lib"
➜  phodav git:(master) export CPPFLAGS="-I/opt/homebrew/opt/libsoup@2/include"

[jpmorrison]

Is icu4c installed? The .pc file doesn't get installed properly (should mention to the package maintainer) I listed how to fix (https://github.com/jpmorrison/OSX-Qemu/issues/7#issuecomment-951465693) but you may need to change if the version is different.

Example:

cd /usr/local/lib/pkgconfig
ln -s ../../Cellar/icu4c/69.1/lib/pkgconfig/icu-uc.pc

Check pkgconfig for libsoup as well. Is there libsoup-2.4.pc or any other version?

cd /usr/local/lib/pkgconfig
ls -l libsoup-* icu-uc.pc

lrwxr-xr-x  1 501  80  47 Oct 25 15:21 icu-uc.pc -> ../../Cellar/icu4c/69.1/lib/pkgconfig/icu-uc.pc

[Tom9876]

Thanks for the hint. I have created the link as you proposed, but haven't checked it :(. In my recent (standard) install of brew the Cellar was in "/opt/homebrew". Using ln -s /opt/homebrew/Cellar/icu4c/69.1/lib/pkgconfig/icu-uc.pc worked for me. Even so this is the only link in "/usr/local/lib/pkgconfig", no issue with libsoup not found anymore Thanks again
