so you are pinging from one VM to another VM on same host in same port group and you have packet loss? if they are on same host in same portgroup, then i guess it must be something inside VM. are the vNIC's supported for the OS? for example "e1000" is not supported in Windows 2016 see VMware Compatibility Guide - Guest/Host Search do you have vmtools installed? are there any errors in VM OS log? duplicate MAC? correct MTU? what kind of OS is installed on both VMs? are you able to ping somewhere without packet loss from that VM?
are they two VM's also on same portgroup? if not then it still must go out to the router and then back on different vlan. and we have similar issue. and it was caused by bad ASIC chip on cisco sw... See more...

Hello, max supported vCPU for Fault Tolerance (FT) is 4 in vSphere 6.x if you want to cover VM with Fault Tolerance decrease vCPU to 4. VMware vSphere Version Comparison | Virten.net

do you have enough space inside your ESXi (log-in  to ESXi shell and type "vdf -h" sometimes missconfigured syslog folder can eat all the space. and then even after restart it doesnt work. but for sure logs from affected ESxi host with timestamps when the issue is observed will be welcome. THanks
Hi, we had similar issue on ESXi 5.5. and it was caused by bug  in AD authentication agent. workaround was to remove ESXi hosts from AD domain (Leave domain). nowdays it is already patched

VMware best practice  about "Power Management BIOS Settings" see page 17. There is info about C-States http://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/vmware-perfbest-practices-vsphere6-0-white-pa… did you install ESXi from VMware ISO or from custom DELL iso? you can find info about supported HW here: VMware Compatibility Guide - System Search I had the workstation version of this DELL T5500 with windows and the power consumption was 143Watt. And nothing special was running there. If you want to save some money (power bill)  and it is just as a lab (nothing production) use Xeon E3- with -L  (Low power consupmtion) ~ 20-40Watt  or Intel NUC boxes.

first few questions.. could you please provide more details about the HW. how many pCPU/pCores frequency, RAM. Storage is local/NFS/FC/? how many vCPU have the other VM's. output from "esxtop"   wait , ready times?  or at least performance of storage counters (latency) and cpu, but counter (Wait, Ready) for memory (swap in, swap out), network packet loss do you have deployed vROPs or vCOPs? good place to start: https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1008360 https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2001003

I would say no, without any other network devices. BUT, I have something similar. And I solve it with mikrotik CHR (cloud hosted router). These CHR are VM's running on each host. and on these CHR1 and CHR2 have public IP's . then you can create VPN + L2 bridge (red line)  (as from your picture you want to have same subnet in both ESXi) beween these two CHR1 and CHR2. OR you can use instead of CHR routers NSX components. but count with high price and you need much more RAM. My recommendation will be at least to have different subnets for VM's in each location. because then you can solve default GW problem. On which host will be def. GW? on ESX1 so then all traffic from VM4,VM5,VM6 needs to go first to ESX1 and then out.

we escalated to Microsoft and VMware support.. .. they escalated to engineering team..  -> ETA ? waiting for new VMtools version.. I hope it will be fixed. latest working VMtools are 9.4.15
sorry overlooked the vDS version is in subject. what works for me: ESXi hosts 6.5.0 - 4564106 vDS - 6.5.0 vCenter 6.5.0 - 4602587 is the vCenter/Host properly licensed?

and what is the vDS version? if is vDS for example version 6.0, was create via thick client or webclient or PowerCLI? in the past when I created vDS via Thick client and then want to do LACP via WebClient .. the LACP option was not there. But when I created the vDS via WebClient, the option was there. similar thread but for older version https://communities.vmware.com/thread/507988?start=0&tstart=0
