An index of Host Related Faults thrown by the VC server during Instant Clone Creation
An article to outline a VC_FAULT_FATAL: Host-related faults.This is a child article of VC_FAULT_FATAL: An Index of Instant Clone Creation Errors returned by Vcenter (90411)
Horizon instructs Vcenter to create virtual machine objects in Vcenter utilizing the Simple Object Access Protocol.When Vcenter fails to complete an instruction, it will return an error response to Horizon with details on the cause.These can be failures on the Esxi Host level.These errors may appear when an ESXi host level issue manifests, which can include but is not limited to Datastore Capacity, Temporary issues with compute, network or storage (for example, a host disconnected)
VC_FAULT_FATAL- An error occurred while communicating with the remote host. This message is sent to Horizon when there is an issue with ESXi host communication.Please verify the health of the ESXi host identified in Horizon Logging as faulting - enter maintenance mode and restart Instant Clone Provisioning fails with a Log Line entry similar to the below in a Connection Server debug file: Location of Horizon (VDM) log files (1027744) 2022-12-20T03:31:04.283-07:00 DEBUG (0EF4-126C) <DesktopControlLdap> [InformationBase] PoolInformation[cn=test ,ou=server groups,dc=vdi,dc=vmware,dc=int]::pae-PendingParentImageErrorMessage is now Fault type is VC_FAULT_FATAL - An error occurred while communicating with the remote host.

This error is sent when there is an incompatibility with the host. This might occur, for example, if no host can satisfy the virtual machine's CPU or memory resource needs or if no host currently has network or storage access needed by the virtual machine.For example, if a virtual machine is configured with GPU hardware and is assigned to an ESXi host with no card.
