Determining if Intel VT is enabled in ESXi 4.x/5.x

To determine if Intel VT or AMD-V are enabled in the BIOS:
  1. Log in to the ESX host as the root user. You can use tools like PUTTY.
  2. Run this command:

    # esxcfg-info|grep "HV Support"
    The output of the HV Support command indicates the type of Hyper-visor support available. These are the descriptions for the possible values:

    0 - VT/AMD-V indicates that support is not available for this hardware.
    1 - VT/AMD-V in    dicates that VT or AMD-V might be available but it is not supported for this hardware.2 - VT/AMD-V indicates that VT or AMD-V is available but is currently not enabled in the BIOS.3 - VT/AMD-V indicates that VT or AMD-V is enabled in the BIOS and can be used.

VMware VRNI 3.5 NTP is working but not healthy

We have experienced this problem where some of the major services not started. You will not be able to connect to the vRNI via web -> https://<ip_address_of_vrni_platform>>. This probably caused by NTP insync. You need to manually start these services. Login with Consoleuser / and default password if not changed before via venter web console. Run services restart and wait for couple minutes (it took me 5-6 mins). Types of Users  User name  Password  Admin UI  admin@local Set this password in the Activate License window during installation. SSH User  support ark1nc0113ct0r CLI User  consoleuser ark1nc0ns0l3 Note It is recommended that the users change the default passwords immediately after the deployment.  Procedure 1 Navigate to  https://<vRealize Network Insight Platform IP address> .  2 Log in to the product UI with the corresponding user name and password.
