6 Spice-GTK - a client-side library to access remote SPICE displays
7
9 Spice-GTK is a library allowing access to remote displays over the
10 SPICE protocol. At the moment It's mainly used to access remote virtual
11 machines.
12
13 The Spice-GTK library provides a set of command line options which can
14 be used to tweak some SPICE-specific option.
15
17 The most basic SPICE URI which can be used is in the form
18 spice://hostname.example.com:5900
19
20 This will try to initiate a SPICE connection to hostname.example.com to
21 port 5900. This connection will be unencrypted. This URI is equivalent
22 to
23 spice://hostname.example.com?port=5900
24
25 In order to start a TLS connection, one would use
26 spice://hostname.example.com?tls-port=5900
27
28 Other valid URI parameters are 'username' and 'password'. Be careful
29 that passing a password through a SPICE URI might cause the password to
30 be visible by any local user through 'ps'.
31
32 Several parameters can be specified at once if they are separated by &
33 or ;
34 spice://hostname.example.com?port=5900;tls-port=5901
35
36 When using 'tls-port', it's recommended to not specify any non-TLS
37 port. If you give both 'port' and 'tls-port', make sure you use the
38 --spice-secure-channels options to indicate which channels must be
39 secure. Otherwise, Spice-GTK first attempts a connection to the non-
40 TLS port, and then try to use the TLS port. This means a man-in-the-
41 middle could force the whole SPICE session to go in clear text
42 regardless of the TLS settings of the SPICE server.
43
45 The following options are accepted when running a SPICE client which
46 makes use of the default Spice-GTK options:
47
48 --spice-secure-channels=<main,display,inputs,...,all>
49 Force the specified channels to be secured
50
51 This instructs the SPICE client that it must use a TLS connection
52 for these channels. If the server only offers non-TLS connections
53 for these channels, the client will not use these. If the special
54 value "all" is used, this indicates that all SPICE channels must be
55 encrypted.
56
57 The current SPICE channels are: main, display, inputs, cursor,
58 playback, record, smartcard, usbredir.
59
60 --spice-disable-effects=<wallpaper,font-smooth,animation,all>
61 Disable guest display effects
62
63 This tells the SPICE client that it should attempt to disable some
64 guest features in order to lower bandwidth usage. This requires
65 guest support, usually through a SPICE agent. This is currently
66 only supported on Windows guests.
67
68 "wallpaper" will disable the guest wallpaper, "font-smooth" will
69 disable font antialiasing, "animation" will try to disable some of
70 the desktop environment animations. "all" will attempt to disable
71 everything which can be disabled.
72
73 --spice-color-depth=<16,32>
74 Guest display color depth
75
76 This tells the SPICE client that it should attempt to force the
77 guest OS color depth. A lower color depth should lower bandwith
78 usage. This requires guest support, usually through a SPICE agent.
79 This is currently only supported on Windows guests.
80
81 --spice-ca-file=<file>
82 Truststore file for secure connections
83
84 This option is used to specify a .crt file containing the CA
85 certificate with which the SPICE server TLS certificates are
86 signed. This is useful when using self-signed TLS certificates
87 rather than certificates signed by an official CA.
88
89 --spice-host-subject=<host-subject>
90 Subject of the host certificate (field=value pairs separated by
91 commas)
92
93 When using self-signed certificates, or when the guest is migrated
94 between different hosts, the subject/altSubject of the TLS
95 certificate the SPICE server will provide will not necessarily
96 match the hostname we are connecting to. This option makes it
97 possible to override the expected subject of the TLS certificate.
98
99 The subject must correspond to the "Subject:" line returned by:
100 openssl x509 -noout -text -in server-cert.pem
101
102 --spice-debug
103 Enable Spice-GTK debugging. This can also be toggled on with the
104 SPICE_DEBUG environment variable, or using G_MESSAGES_DEBUG=all
105
106 --spice-disable-audio
107 Disable audio support
108
109 --spice-disable-usbredir
110 Disable USB redirection support
111
112 --spice-usbredir-auto-redirect-filter=<filter-string>
113 Filter selecting USB devices to be auto-redirected when plugged in
114
115 This filter specifies which USB devices should be automatically
116 redirected when they are plugged in during the lifetime of a SPICE
117 session.
118
119 A rule has the form of: "class,vendor,product,version,allow"
120
121 -1 can be used instead of class, vendor, product or version in
122 order to accept any value. Several rules can be concatenated with
123 '|': "rule1|rule2|rule3"
124
125 --spice-usbredir-redirect-on-connect=<filter-string>
126 Filter selecting USB devices to redirect on connect
127
128 This filter specifies which USB devices should be automatically
129 redirected when a SPICE connection to a remote display has been
130 established.
131
132 --spice-gtk-version
133 Display Spice-GTK version information
134
135 --spice-smartcard
136 Enable smartcard support
137
138 --spice-smartcard-db=<certificate-db>
139 Path to the local certificate database to use for software
140 smartcard certificates
141
142 This option is only useful for testing purpose. Instead of having a
143 hardware smartcard reader, and a physical smartcard, you can
144 specify a file containing 3 certificates which will be used to
145 emulate a smartcard in software. See
146 "http://www.spice-space.org/page/SmartcardUsage#Using_a_software_smartcard"
147 for more details about how to generate these certificates.
148
149 --spice-smartcard-certificates=<certificates>
150 Certificates to use for software smartcards (field=values separated
151 by commas)
152
153 This option is only useful for testing purpose. This allows to
154 specify which certificates from the certificate database specified
155 with --spice-smartcard-db should be used for smartcard emulation.
156
157 --spice-cache-size=<bytes>
158 Image cache size
159
160 This option should only be used for testing/debugging.
161
162 --spice-glz-window-size=<bytes>
163 Glz compression history size
164
165 This option should only be used for testing/debugging.
