Set Key Management Server Certificate Expiration
Threshold
By default, vCenter Server notifies you 30 days before your Key Management Server (KMS) certificates
expire. You can change this default value.
KMS certificates have an expiration date. When the threshold for the expiration date is reached, an alarm
notifies you.
vCenter Server and KMS clusters exchange two types of certificates: server and client. The VMware
Endpoint Certificate Store (VECS) on the vCenter Server system stores the server certificates and one
client certificate per KMS cluster. Because there are two certificate types, there are two alarms for each
certificate type (one for client, one for server).
Procedure
1 Log in to the vSphere Web Client, and select a vCenter Server system.
2 Click the Configure tab.
3 Under Settings, click Advanced System Settings, and click Edit.
4 Either filter for, or scroll to the vpxd.kmscert.threshold configuration parameter.
5 Enter your value in days and click OK.
vSphere Virtual Machine Encryption and Core Dumps
If your environment uses vSphere Virtual Machine Encryption, and if an error occurs on the ESXi host, the
resulting core dump is encrypted to protect customer data. Core dumps that are included in the vm-
support package are also encrypted.
Note Core dumps can contain sensitive information. Follow your organization's data security and privacy
policy when handling core dumps.
Core Dumps on ESXi Hosts
When an ESXi host, a user world, or a virtual machine crashes, a core dump is generated, and the host
reboots. If the ESXi host has encryption mode enabled, the core dump is encrypted using a key that is in
the ESXi key cache. This key comes from the KMS. See How vSphere Virtual Machine Encryption
Protects Your Environment for background information.
The following table shows encryption keys used for each core dump type, by vSphere release.
