      • Route RPKI validation April 1st, 2022
        RPKI is a security framework by which network owners can validate and secure the critical route updates or Border Gateway Protocol (BGP) announcements between public Internet networks. BGP is essentially the central nervous system of the Internet and one of its fundamental building blocks. The main function of BGP is to facilitate efficient routing between Autonomous Systems (AS), by building and maintaining the Internet routing table. The Internet routing table is effectively the navigation system of the Internet and without it, traffic would be unable to flow between its constituent networks. Unfortunately, routing equipment alone cannot distinguish between legitimate and malicious routing announcements,...

      Paolo Caparrelli VMware 22 June 2022

      This issue occurs due to CBT enabled in the parent image:

      Resolution

      To enable or disable CBT on a virtual machine, perform the appropriate steps given for enabling or disabling:
       
      Note: Ensure that the virtual machine is powered off before performing these steps.

      To enable CBT in a virtual machine:
      1. Power off the virtual machine.
      2. Right-click the virtual machine and click Edit Settings.
      3. Click the Options tab.
      4. Click General under the Advanced section and then click Configuration Parameters. The Configuration Parameters dialog opens.
      5. Click Add Row.
      6. Add the ctkEnabled parameter and then set its value to true.
      7. Click Add Row, add scsi0:0.ctkEnabled, and set its value to true.

        Note: scsi0:0 in scsi0:0.ctkEnabled indicates the SCSI device assigned to the hard disk that is added to the virtual machine. Every hard disk added to the virtual machine is given a SCSI device that appears similar to scsi0:0, scsi0:1, or scsi 1:1. CBT is enabled (or disabled) individually on each disk.

      8. Power on the virtual machine.
      9. In the home directory of the virtual machine, verify that each disk having CBT enabled has also a vmname-ctk.vmdk file.
      To disable CBT, ensure that there are no snapshots on the virtual machine. For more information, see Consolidating snapshots in ESX/ESXi 3.x and 4.x (1007849) and Consolidating snapshots in vSphere 5.x/6.0 (2003638).
       
      To disable CBT:
      1. Power off the virtual machine.
      2. Right-click the virtual machine and click Edit Settings.
      3. Click the Options tab.
      4. Click General under the Advanced section and then click Configuration Parameters. The Configuration Parameters dialog opens.
      5. Set the ctkEnabled parameter to false for the desired SCSI disk(s).
      6. Power on the virtual machine.
