Hey Chris, I do not attach two ifaces to the same vswitch in vsphere. This makes you have two ifaces in the same subnet... and there is no stp for loop-free guarantee.
I think it is possible that when you enable the veth from HV, it sends out the IPv6 multicast pkts => if you have another VM with to ifaces attached to the same vswitch => then the pkts will be looped back. Could you try creating two vswitch in vsphere and separate the interfaces (i.e. ens192 and ens224)?
