Is vmci/vsock missing?

https://github.com/vmware/open-vm-tools/blob/master/open-vm-tools/lib/include/vmci_sockets.h

define VMCI_SOCKETS_DEFAULT_DEVICE "/dev/vsock"

define VMCI_SOCKETS_CLASSIC_ESX_DEVICE "/vmfs/devices/char/vsock/vsock"

if defined(linux)

define VMCI_SOCKETS_VERSION 1972

define VMCI_SOCKETS_GET_AF_VALUE 1976

define VMCI_SOCKETS_GET_LOCAL_CID 1977

define VMCI_SOCKETS_UUID_2_CID 1991

[thelounge-zz]

surely blacklisted for years because nobody needs that stuff, poero-operations, vmware-ha and backups are working, anything else is useless

[dsouders]

vmci/vsock should be installed. The drivers are used by open-vm-tools to provide a variety of services, including secure RPCs that are needed to manage VMs.

[thelounge-zz]

they are not needed for Vmware-HA, Vmware-DataProtection, SHotduwn/Reboot guests and so should not be loaded on setups wehere virtual machines are handeled like a physical machine

all that services are not needed and not wanted in stripped setups and after 12 years i know my setups, better than VMware knows their stuff where your whole network disappears after a bugfix ESXi update without manual internevntion (god knows why a failing secondary onobard NIC kills the whole teaming when the 10 GBE NIC would work just fine and does on a different port for NFS)

On the ESXi command line, run these commands to disable the ntg3 driver and enable the tg3 driver:

esxcfg-module -d ntg3

esxcfg-module -e tg3

[Piraty]

I hit this as well, no fancy setup in place (no blacklisted modules).
The issue appears in linux > 5.4 (5.6, 5,7 so far)
