6 virsh_selinux - Security Enhanced Linux Policy for the virsh processes
7
9 Security-Enhanced Linux secures the virsh processes via flexible manda‐
10 tory access control.
11
12 The virsh processes execute with the virsh_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep virsh_t
19
20
21
23 The virsh_t SELinux type can be entered via the virsh_exec_t file type.
24
25 The default entrypoint paths for the virsh_t domain are the following:
26
27 /usr/sbin/xl, /usr/sbin/xm, /usr/bin/virsh
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 virsh policy is very flexible allowing users to setup their virsh pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for virsh:
40
41 virsh_t, virsh_ssh_t
42
43 Note: semanage permissive -a virsh_t can be used to make the process
44 type virsh_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. virsh
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run virsh with the tightest access possible.
53
54
55
56 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58
59 setsebool -P fips_mode 1
60
61
62
63 If you want to allow confined applications to use nscd shared memory,
64 you must turn on the nscd_use_shm boolean. Enabled by default.
65
66 setsebool -P nscd_use_shm 1
67
68
69
70 If you want to allow confined virtual guests to manage nfs files, you
71 must turn on the virt_use_nfs boolean. Disabled by default.
72
73 setsebool -P virt_use_nfs 1
74
75
76
77 If you want to allow confined virtual guests to manage cifs files, you
78 must turn on the virt_use_samba boolean. Disabled by default.
79
80 setsebool -P virt_use_samba 1
81
82
83
85 The SELinux process type virsh_t can manage files labeled with the fol‐
86 lowing file types. The paths listed are the default paths for these
87 file types. Note the processes UID still need to have DAC permissions.

156 SELinux requires files to have an extended attribute to define the file
157 type.
158
159 You can see the context of a file using the -Z option to ls
160
161 Policy governs the access confined processes have to these files.
162 SELinux virsh policy is very flexible allowing users to setup their
163 virsh processes in as secure a method as possible.
164
165 The following file types are defined for virsh:
166
167
168
169 virsh_exec_t
170
171 - Set files with the virsh_exec_t type, if you want to transition an
172 executable to the virsh_t domain.
173
174
175 Paths:
176 /usr/sbin/xl, /usr/sbin/xm, /usr/bin/virsh
177
178
179 Note: File context can be temporarily modified with the chcon command.
180 If you want to permanently change the file context you need to use the
181 semanage fcontext command. This will modify the SELinux labeling data‐
182 base. You will need to use restorecon to apply the labels.
183
184
186 semanage fcontext can also be used to manipulate default file context
187 mappings.
188
189 semanage permissive can also be used to manipulate whether or not a
190 process type is permissive.
191
192 semanage module can also be used to enable/disable/install/remove pol‐
193 icy modules.
194
195 semanage boolean can also be used to manipulate the booleans
196
197
198 system-config-selinux is a GUI tool available to customize SELinux pol‐
199 icy settings.
