A custom bug ID has been generated as the vendor did not provide one: 467c79ccd827
In very specific circumstances, when a vSphere vMotion operation on a virtual machine runs in parallel with an operation that sends VMCI datagrams, services that use VMCI datagrams might see unexpected communication or loss of communication. Under the same conditions, the issue can also happen when restoring a memory snapshot, resuming a suspended VM or using CPU Hot Add. As a result, the guest operating system that depends on services communicating over VMCI might become unresponsive. The issue might also affect services that use vSockets over VMCI. This problem does not impact VMware Tools. The issue is specific for VMs on hardware version 20 with a Linux distribution that has specific patches introduced in Linux kernel 5.18 for a VMCI feature, including but not limited to up-to-date versions of RHEL 8.7, Ubuntu 22.04 and 22.10, and SLES15 SP3, and SP4. For more information, see VMware knowledge base article 89683.
