10 VirtualDomain [start | stop | status | monitor | migrate_to |
11 migrate_from | meta-data | validate-all]
12
14 Resource agent for a virtual domain (a.k.a. domU, virtual machine,
15 virtual environment etc., depending on context) managed by libvirtd.
16 This resource agent may be configured for native migration if available
18 in the cluster manager. For Pacemaker, the allow-migrate="true" meta
19 attribute enables native migration.
20
22 config
23 Absolute path to the libvirt configuration file, for this virtual
24 domain.
25 (unique, required, string, no default)
27 hypervisor
29 Hypervisor URI to connect to. See the libvirt documentation for
30 details on supported URI formats. The default is system dependent.
31 Determine the system's default uri by running 'virsh --quiet uri'.
32 (optional, string, no default)
34 force_stop
36 Always forcefully shut down ("destroy") the domain on stop. The
37 default behavior is to resort to a forceful shutdown only after a
38 graceful shutdown attempt has failed. You should only set this to
39 true if your virtual domain (or your virtualization backend) does
40 not support graceful shutdown.
41 (optional, boolean, default 0)
43 migration_transport
45 Transport used to connect to the remote hypervisor while migrating.
46 Please refer to the libvirt documentation for details on transports
47 available. If this parameter is omitted, the resource will use
48 libvirt's default transport to connect to the remote hypervisor.
49 (optional, string, no default)
51 migration_user
53 The username will be used in the remote libvirt
54 remoteuri/migrateuri. No user will be given (which means root) in
55 the username if omitted
56 If remoteuri is set, migration_user will be ignored.
58 (optional, string, no default)
60 migration_downtime
62 Define max downtime during live migration in milliseconds
63 (optional, integer, default 0)
65 migration_speed
67 Define live migration speed per resource in MiB/s
68 (optional, integer, default 0)
70 migration_network_suffix
72 Use a dedicated migration network. The migration URI is composed by
73 adding this parameters value to the end of the node name. If the
74 node name happens to be an FQDN (as opposed to an unqualified host
75 name), insert the suffix immediately prior to the first period (.)
76 in the FQDN. At the moment Qemu/KVM and Xen migration via a
77 dedicated network is supported.
78 Note: Be sure this composed host name is locally resolvable and the
80 associated IP is reachable through the favored network. This suffix
81 will be added to the remoteuri and migrateuri parameters.
82 See also the migrate_options parameter below.
84 (optional, string, no default)
86 migrateuri
88 You can also specify here if the calculated migrate URI is
89 unsuitable for your environment.
90 If migrateuri is set then migration_network_suffix, migrateport and
92 --migrateuri in migrate_options are effectively ignored. Use "%n"
94 as the placeholder for the target node name.
95 Please refer to the libvirt documentation for details on guest
97 migration.
98 (optional, string, no default)
100 migrate_options
102 Extra virsh options for the guest live migration. You can also
103 specify here --migrateuri if the calculated migrate URI is
104 unsuitable for your environment. If --migrateuri is set then
105 migration_network_suffix and migrateport are effectively ignored.
106 Use "%n" as the placeholder for the target node name.
107 Please refer to the libvirt documentation for details on guest
109 migration.
110 (optional, string, no default)
112 monitor_scripts
114 To additionally monitor services within the virtual domain, add
115 this parameter with a list of scripts to monitor.
116 Note: when monitor scripts are used, the start and migrate_from
118 operations will complete only when all monitor scripts have
119 completed successfully. Be sure to set the timeout of these
120 operations to accommodate this delay.
121 (optional, string, no default)
123 autoset_utilization_cpu
125 If set true, the agent will detect the number of domainU's vCPUs
126 from virsh, and put it into the CPU utilization of the resource
127 when the monitor is executed.
128 (optional, boolean, default true)
130 autoset_utilization_host_memory
132 If set true, the agent will detect the number of *Max memory* from
133 virsh, and put it into the host_memory utilization of the resource
134 when the monitor is executed.
135 (optional, boolean, default true)
137 autoset_utilization_hv_memory
139 If set true, the agent will detect the number of *Max memory* from
140 virsh, and put it into the hv_memory utilization of the resource
141 when the monitor is executed.
142 (optional, boolean, default true)
144 unset_utilization_cpu
146 If set true then the agent will remove the cpu utilization resource
147 when the monitor is executed.
148 (optional, boolean, default false)
150 unset_utilization_host_memory
152 If set true then the agent will remove the host_memory utilization
153 resource when the monitor is executed.
154 (optional, boolean, default false)
156 unset_utilization_hv_memory
158 If set true then the agent will remove the hv_memory utilization
159 resource when the monitor is executed.
160 (optional, boolean, default false)
162 migrateport
164 This port will be used in the qemu migrateuri. If unset, the port
165 will be a random highport.
166 (optional, integer, no default)
168 remoteuri
170 Use this URI as virsh connection URI to commuicate with a remote
171 hypervisor.
172 If remoteuri is set then migration_user and
174 migration_network_suffix are effectively ignored. Use "%n" as the
175 placeholder for the target node name.
176 Please refer to the libvirt documentation for details on guest
178 migration.
179 (optional, string, no default)
181 save_config_on_stop
183 Changes to a running VM's config are normally lost on stop. This
184 parameter instructs the RA to save the configuration back to the
185 xml file provided in the "config" parameter.
186 (optional, boolean, no default)
188 sync_config_on_stop
190 Setting this automatically enables save_config_on_stop. When
191 enabled this parameter instructs the RA to call csync2 -x to
192 synchronize the file to all nodes. csync2 must be properly set up
193 for this to work.
194 (optional, boolean, no default)
196 snapshot
198 Path to the snapshot directory where the virtual machine image will
199 be stored. When this parameter is set, the virtual machine's RAM
200 state will be saved to a file in the snapshot directory when
201 stopped. If on start a state file is present for the domain, the
202 domain will be restored to the same state it was in right before it
203 stopped last. This option is incompatible with the 'force_stop'
204 option.
205 (optional, string, no default)
207 backingfile
209 When the VM is used in Copy-On-Write mode, this is the backing file
210 to use (with its full path). The VMs image will be created based on
211 this backing file. This backing file will never be changed during
212 the life of the VM.
213 (optional, string, no default)
215 stateless
217 If set to true and backingfile is defined, the start of the VM will
218 systematically create a new qcow2 based on the backing file,
219 therefore the VM will always be stateless. If set to false, the
220 start of the VM will use the COW (<vmname>.qcow2) file if it
221 exists, otherwise the first start will create a new qcow2 based on
222 the backing file given as backingfile.
223 (optional, boolean, default false)
225 copyindirs
227 List of directories for the virt-copy-in before booting the VM.
228 Used only in stateless mode.
229 (optional, string, no default)
231 shutdown_mode
233 virsh shutdown method to use. Please verify that it is supported by
234 your virsh toolsed with 'virsh help shutdown' When this parameter
235 is set --mode shutdown_mode is passed as an additional argument to
236 the 'virsh shutdown' command. One can use this option in case
237 default acpi method does not work. Verify that this mode is
238 supported by your VM. By default --mode is not passed.
239 (optional, string, no default)
241 start_resources
243 Start the virtual storage pools and networks used by the virtual
244 machine before starting it or before live migrating it.
245 (optional, boolean, default false)
247

250 start
252 Starts the resource. Suggested minimum timeout: 90s.
253 stop
