用法
虚拟机生命周期
如何创建、修改、启动、停止和删除虚拟机：
import ovmclient
from ovmclient import constants
client = ovmclient.Client(
'https://host:7002/ovm/core/wsapi/rest', 'admin', 'yadayada')
# Make sure the manager is running
client.managers.wait_for_manager_state()
repo_id = client.repositories.get_id_by_name('repo1')
pool_id = client.server_pools.get_id_by_name('pool1')
network_id = client.networks.get_id_by_name('management')
# Create a virtual disk
disk_data = {
'diskType': constants.DISK_TYPE_VIRTUAL_DISK,
'size': 1024 * 1024 * 1024,
'shareable': False,
'name': 'dummy.img',
}
job = client.jobs.wait_for_job(
client.repository_virtual_disks(repo_id).create(disk_data, sparse='true'))
disk_id = job['resultId']
# Create a VM
vm_data = {
'name': 'vm1',
'description': 'Blah',
'vmDomainType': constants.VM_DOMAIN_TYPE_XEN_HVM_PV_DRIVERS,
'repositoryId': repo_id,
'serverPoolId': pool_id,
'cpuCount': 4,
'cpuCountLimit': 4,
'hugePagesEnabled': False,
'memory': 1024,
'memoryLimit': 1024,
'osType': 'Oracle Linux 7',
}
job = client.jobs.wait_for_job(client.vms.create(vm_data))
vm_id = job['resultId']
# Map the virtual disk
vm_disk_mapping_data = {
'virtualDiskId': disk_id,
'diskWriteMode': constants.DISK_WRITE_MODE_READ_WRITE,
'emulatedBlockDevice': False,
'storageElementId': None,
'diskTarget': 0,
}
job = client.jobs.wait_for_job(
client.vm_disk_mappings(vm_id).create(vm_disk_mapping_data))
# Add a vnic
vnic_data = {
'networkId': network_id,
}
client.jobs.wait_for_job(client.vm_virtual_nics(vm_id).create(vnic_data))
# Retrieve the VM
vm = client.vms.get_by_id(vm_id)
# Update the VM, e.g. setting a new name
vm['name'] = 'vm2'
client.jobs.wait_for_job(client.vms.update(vm_id, vm))
# Start the VM
client.jobs.wait_for_job(client.vms.start(vm_id))
# Kill the VM
client.jobs.wait_for_job(client.vms.kill(vm_id))
# Delete the VM
client.jobs.wait_for_job(client.vms.delete(vm_id))
# Delete the virtual disk
client.jobs.wait_for_job(
client.repository_virtual_disks(repo_id).delete(disk_id))
克隆虚拟机
如何克隆虚拟机或虚拟机模板：
import ovmclient
client = ovmclient.Client(
'https://host:7002/ovm/core/wsapi/rest', 'admin', 'yadayada')
# Make sure the manager is running
client.managers.wait_for_manager_state()
pool_id = client.server_pools.get_id_by_name('pool1')
# Get an existing VM or a VM template
vm_id = client.vms.get_id_by_name('vm1')
# Set to True to create a VM template, False for a regular VM
create_template = True
# Clone the VM
job = client.jobs.wait_for_job(
client.vms.clone(vm_id, pool_id, create_template=create_template))
new_vm_id = job['resultId']
# Rename the VM template
data = client.vms.get_by_id(new_vm_id)
data["name"] = 'new_name'
client.jobs.wait_for_job(client.vms.update(new_vm_id, data))
# Delete the VM template
client.jobs.wait_for_job(client.vms.delete(new_vm_id))
发现服务器
如何发现和拥有未拥有的Oracle虚拟机主机：
import ovmclient
client = ovmclient.Client(
'https://host:7002/ovm/core/wsapi/rest', 'admin', 'yadayada')
# Make sure the manager is running
client.managers.wait_for_manager_state()
# Discover a new host and take ownership
client.servers.discover('newovmhost')
