Re: [libvirt] [Xen-devel] [PATCH 4/4] xenconfig: fix spice mousemode and copypaste



2015-05-09 0:00 GMT+02:00 Jim Fehlig <jfehlig suse com>:
From xl.cfg950 man page:

spiceagent_mouse=BOOLEAN
Whether SPICE agent is used for client mouse mode. The default is
true (1) (turn on)

spicevdagent=BOOLEAN
Enables spice vdagent. The Spice vdagent is an optional component for
enhancing user experience and performing guest-oriented management
tasks. Its features includes: client mouse mode (no need to grab
mouse by client, no mouse lag), automatic adjustment of screen
resolution, copy and paste (text and image) between client and domU.
It also requires vdagent service installed on domU o.s. to work.
The default is 0.

spice_clipboard_sharing=BOOLEAN
Enables Spice clipboard sharing (copy/paste). It requires spicevdagent
enabled. The default is false (0).

So if spiceagent_mouse is enabled (client mouse mode) or
spice_clipboard_sharing is enabled, spicevdagent must be enabled.
Along with this change, s/spicedvagent/spicevdagent, set
spiceagent_mouse correctly, and add a test for these spice
features.

Thanks for your work in libvirt about improve/fix support for xen with spice.
From a fast look to code seems there is spice usbredirection support missed, a feature that I think very useful:
http://xenbits.xen.org/gitweb/?p=xen.git;a=commitdiff;h=f5414ee57a17500e650ea11766474b11da940da2
There are also other spice settings added for xen 4.6 (image compression and streaming video):
http://xenbits.xen.org/gitweb/?p=xen.git;a=commitdiff;h=bd71555985efc423b1a119b6a3177de855763453
http://xenbits.xen.org/gitweb/?p=xen.git;a=commitdiff;h=296c7f3284efe655d95a8ae045a5dc1a20d6fff0
And also another important that you already know and accepted today:
http://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=161212ef02312c0681d2d809c8ff1e1f0ea6f6f9
Latest version have also LIBXL_HAVE_QXL useful for libvirt.
I think is good add also qxl and usbredir to spice-features test or create a new one "full features".
