I would agree with that. Will test it in the near future as well but I think the problem will still be overall performance if you are running some additional services apart from VMM. Curious to test both 718 and 918 soon.

Well, I have to agree on this. Comparing 918 and my 3614 in regards to VM speed and usage, 3614 is a far better choice. Still wondering how all will play out when 918 will be running with full SSD setup.

I would not put blame on Synology as they use what they could from open source (KVM/Redhat).
It is QEMU based, not KVM. So its a type-2 hypervisor running in userland running hardware virtualization, not kernel-space type-1 hardware-assisted virtualization.

Dynamic Binary translation on a Celeron CPU is never going to set speed records. Now, if Synology could get KVM running and use that for VMM, then we'd be seeing usable W10 VMs on a DS918.

Thank you for correction and clarification. Yes, type-1 would be highly welcomed although it seems that Synology will stick with current solution. As we learned yesterday, on future follow-on models we can expect a very small increment in CPU department (still 4 core low-powered SoC Celeron) so nothing big there either.

I am running a few VM's on an ISCSI LUN - don't have the need for them as much these days, my free VMWare licensing is out of date as well

Yep, that's why I have a couple of NUCs running VMware, and just use the NAS as an NFS datastore. Even an old Gen6 i3 NUC is a decent upgrade from the Celeron J-series. A Skull Canyon NUC is even better, and they sit VERY nicely on top of a DS918, just saying.... ;-)

Sounds cozy. I was hoping to snatch NUC with 2 built-in NICs so it can host Untangle FW, but so far I fell short of finding one. There are some cheaper Chinese boxes (QOTOM) which looks OK, but I'd prefer something built with some active support.

Plenty of USB NICs around in both USB-A & USB-C flavours, then just run the VMware Fling for USB-LAN adaptors. perfectly fine for home lab and non-production use. The Realtek 8152-based models seem pretty solid under vSphere 6.7.
