| overProvisioning.memory |
The memory overcommitment. This parameter is used to control the
virtual memory size allocated to a VM instance. Default: 1. Formula:
Physical memory size x Memory overcommit = Allocable virtual memory
size. |
1 |
[1.00,+∞) |
| distributeImage.concurrency |
The concurrency of distributing images to a Local Storage primary
storage. Default: 2. |
2 |
[0,+∞) |
| hostAllocatorStrategy |
The policy used to allocate hosts to VM instances migrated from
the VMware platform to the KVM platform. Default:
LeastVmPreferredHostAllocatorStrategy. |
LeastVmPreferredHostAllocatorStrategy |
- LeastVmPreferredHostAllocatorStrategy
- MinimumCPUUsageHostAllocatorStrategy
- MinimumMemoryUsageHostAllocatorStrategy
|
| distributeImage |
Specifies whether to distribute an image to a Local Storage
primary storage when the image is added to a backup storage.
Default: true. |
true |
|
| threshold.primaryStorage.physicalCapacity |
The usage threshold of a primary storage. Default: 0.9. You can
set this parameter to avoid excessive usage of primary storage
space. If you set the Primary Storage Overcommit parameter, we
recommend that you set this parameter. This prevents excessive
attaching of volumes and the ensuing crashes of VM instances. |
0.9 |
(0,1.00] |
| overProvisioning.primaryStorage |
The primary storage overcommitment. This parameter is used to
control the size of virtual primary storage space allocated to a VM
instance. Default: 1.00, double. Formula: Physical primary storage
size x Primary storage overcommit = Allocable virtual primary
storage size. |
1.0 |
[1.00,+∞) |
| apiRetry.vm |
The number of retries if a VM instance fails to be created or
started. Default: 0. |
0 |
[0,+∞) |
| apiRetry.interval.vm |
The interval of retries if a VM instance fails to
be created or started. Default: 3. Unit: second. |
3 |
[0,+∞) |
| aio.native |
Specifies whether to enable kernel AIO. Default:
false. If set to true, make sure that VM Cache Mode is set to none. |
false |
|
| ui.operation.max.history |
The retention period of operation logs. Default:
90. Unit: day. Operation logs that exceed the retention period
threshold are expunged. |
90 |
[1,+∞) |
| xfsFragScrape.interval |
The interval of sampling the monitoring data of
the fragmentation of XFS file systems. Default: 12. Unit: hour.
Valid values: 1 to positive infinity, integer. |
12 |
[1,+∞) |
| xfsVolumeDetect.size |
The threshold of the volume size exceeding which
XFS fragmentation inspection is triggered. Default: 100. Unit:
GiB. |
100 |
[0,+∞) |
| deleteTempImages |
Specifies whether to enable auto-deletion of
temporary images generated while cloning VM instances or recovering
VM instances or volumes from backups. Default: false. |
false |
|
| license.scrape.interval |
The interval that the system obtains the latest
license information. Default: 3600. Unit: second. |
3600 |
[0,+∞) |
| enableSpiceChannelSupportTLS |
Specifies whether to enable TLS encryption for
SPICE channels. Default: 0. Eight channels are available. They are
main, display, inputs, cursor, playback, record, smartcard, usbredir
in ascending order of bit significance. For example, if you set the
value to 1, TLS encryption is enabled for the main channel. If you
set the value to 3, TLS encryption is enabled for the main channel
and the display channel. If you set the value to 255, TLS encryption
is enabled for all SPICE channels. Please note that you need to
reconnect to hosts and restart VM instances before the TLS
encryption takes effect. |
0 |
[0,255] |
| vm.consoleMode |
The type of protocol used to connect to the
console of a VM instance. Default: vnc. Valid values: vnc, spice,
and vncAndSpice. If you set this parameter on the details page of a
VM instance, this global setting does not take effect on the VM
instance. In addition, if you modify the console mode, you must
restart a VM instance before the modification takes effects on the
VM instance. |
vnc |
|
| default.login.portal |
The default login portal. Default: iam-and-iam2.
This value indicates that when you log in to the platform, the main
login portal and project login portal are displayed. If you set the
value to iam2, when you log in to the platform, the project login
portal is displayed. |
iam-and-iam2 |
|
| vm.console.password.strength.check.config |
Specifies whether to set a password for VNC
console login. Default: false. The length range of a password is in
the format of m-n. Default: 6-8. You can set a password length that
ranges from 6 to 32. You can also enable the combination of digits,
lowercase letters, uppercase letters, and special characters for a
password. |
false |
|
| vm.password.strength.check.config |
Specifies whether to set login passwords for VM
instances. Default: false. If you set a login password, please note
the following: The length range of a password is in the format of
m-n. Default: 8-18. The length of a password ranges from 8 to 18.
Before you set a login password for a VM instance, make sure that
cloud-init is installed in the system image of the VM instance. We
recommend that the version of cloud-init be 0.7.9, 17.1, 19.4, 19.4,
or later. |
false |
|
| auto.set.vm.nic.multiqueue |
Specifies whether to enable multi-queue upgrading
for vNICs of VM instances. Default: true. This value indicates that
when a VM instance is started for the first time, the system
automatically upgrades the number of queues for each vNIC based on
the number of vCPUs of the VM instance. This helps improve the
performance of the VM instance. The maximum number of queues for
each vNIC is 12. |
