| cleanTraffic |
Specifies whether to enable the feature of defending against IP
spoofing or MAC spoofing attacks for a VM instance. Default:
false. |

|
| deletionPolicy |
The policy used to delete VM instances. Default:
Delay. Valid values: Direct, Delay, and Never.
- Direct: If you delete a VM instance, the VM instance is
deleted at once.
- Delay: If you delete a VM instance, the VM instance is
listed on the Deleted tab of the VM instance management page
and is in Deleted state. If you set the value to Delay, you
can set the retention period of deleted VM instances. The
default retention period is 86,400 seconds. When the
retention period expires or if you expunge a deleted VM
instance, the VM instance is expunged.
- Never: If you delete a VM instance, the system does not
automatically expunge the deleted VM instance.

VM instance to NULL after the instance offering of the VM instance
is deleted. Default: true. |

|
| kvmHiddenState |
Specifies whether to hide the KVM virtualization flag. Default:
false. If set to true, <hidden state='on'> is inserted in the
<kvm> field of the XML file defined for a newly started VM
instance. If you use NVIDA video cards for VM instances, you need to
set this parameter to true. |
false |
|
| numa |
Default: false. If set to true, you can modify the number of
vCPUs and memory size of a VM instance online. We recommend that you
do not modify the number of vCPUs and memory size of a Windows-based
VM instance in the production environment. Please excise with
caution. |
false |
|
| spiceStreamingMode |
- all: All video frames are encoded, compressed, and then
transferred. This lowers bandwidth requirements, promotes
streaming fluency, while increases the CPU pressure of thin
clients.
- filter: Incremental video frames are encoded, compressed,
and then transferred. Compared with the all mode, this mode
further lowers bandwidth requirements and promotes streaming
fluency. The CPU pressure of thin clients is relatively low.
However, Chrome flash of thin clients will cause streaking
issues.
- off: Video frames are not encoded or compressed before
transmission. This produces HD video streaming while have
highest requirements for bandwidth. The CPU pressure of thin
clients is the lowest among the three modes.

off |
|

- qxl: provides high performance video features when used with
the SPICE protocol.
- cirrus: Not recommended.

virtio |
|
| soundType |
The type of voice card that is used when a VM instance is started
up. Default: HDA(ICH6). Valid values: AC97, HDA(ICH6), and
HDA(ICH9). Note: If the console mode of a VM instance is vnc, set
the VM console mode to spice or vnc + spice and restart the VM
instance. Then this global setting will take effect on this VM
instance. |

Specifies whether to delete attached data volumes while deleting
a VM instance. Default: false. |
false |

Specifies whether to enable VMware I/O port simulation. Default:
false. |
false |
|
| vmDefaultCdRomNum |
The default number of virtual drives that the system creates for
a VM instance (the cdrom parameter is not specified). Default: 1.
Valid values: 1, 2, and 3. This setting does not take effect on the
VM instances whose number of virtual drives has exceeded the
threshold. |
1 |
|
| maximumCdRomNum |
The maximum of virtual drives that can be created for a VM
instance. Default: 3. Valid values: 1, 2, and 3. This setting does
not take effect on the VM instances whose number of virtual drives
has exceeded the threshold. |
3 |
|
| pciePortNums |
The number of PCIe root ports that can be configured for a x86-64
VM instance with Q35 motherboard. Default: 28. Valid values: 0 to
28. This setting predefines the number of PCIe devices that can be
hot plugged during VM startup. Modifications of the setting on a VM
instance take effect after you restart the VM instance. |
28 |
0-28 |
| multivNic.support |
Specifies whether to enable multi-vNIC configuration in the same
IP range. Default: false. This value indicates that you can
configure only one vNIC for a VM instance in the same private IP
range. If set to true, you can configure multiple vNICs for a VM
instance in the same private IP range. |
false |
|
| resourceBinding.strategy |
Specifies the binding strength for instances
bound with clusters. Default: Soft.
- Hard: Instances must start in the current cluster.
- Soft: Instances are prioritized to start in the current
cluster. If the current cluster has no available hosts,
instances can start in other clusters.
|

| vm.ha.across.clusters |
Specifies whether to allow instances'
cross-cluster migrations.
- true: Allow cross-cluster migrations.
- false: Deny cross-cluster migrations.
|
true |

| crash.strategy |
Specifies whether to enable error inspection for VM instances.
Default: false. If you enable error inspection, you can set the
error handling policy. Three error handling polices are available:
Preserve, Reboot, and Shutdown. If your VM instance crashes, the VM
instance is handled based on the configured policy. Note that before
you can enable error inspection, you must install GuestTools of the
latest version and make sure the agent is in Running state. |
false |
|
| crash.rebootThreshold.duration |
The restart policy of VM instances upon errors.
Default: Restart VM instance up to five times within 30 minutes. If

- Specifies whether to sync Windows VM time with the host BIOS
time. If enabled, Windows VM time is the same as that of the
host. By default, the sync is enabled.
- The time synchronization setting does not take effect on
Linux VM instances.
- If you specifically set time sync for a VM instance, the
global setting does not take effect on the VM instance.

devices attached to a VM instance. Default: true. |
true |
|
| enable.vm.internal.ip.overwrite |
Specifies whether to allow the NIC IP configured
in the VM instance to overwrite the NIC IP record existing on the

- To use this feature, install GuestTools for VM instances
in advance.
- The NIC IP configured in the VM instance overwrites the
IP record on the Cloud after you set this setting to
true and the system detects that the NIC IP
changes.
- If you want to make the NIC IP configured in the VM
instance overwrite the IP record on the Cloud, we
recommend that you set this setting to true before you
enter the VM instance and configure the IP.
