Hello,

we need for specal VM's (we get they in hyperv) an nested hyperv on Proxmox. Does anybody know about, is this running? We need that from Server 2012r2 and 2016.

Thanks
 
afaik hyper-v nested in kvm does not work
 
Hi all,

I did several tests (PVE 4.x) and it seems its not yet fixed. Our clients seem to need this feature lately and we cant do anything.

Did anyone accomplished it with PVE 5.x versions?

offtopic: Also Docker for windows has problems, but its still in beta.
 
Should work, but you need at least a 4.10 kernel.

(do it will never work on Proxmox VE 4.4, only 5.x)
 
Hey,

Things are getting better nowadays : lastest PVE 5.1 can run Win2012r2 + Hyper-V role, and a L2 VM can start in 2012R2. Didn't try W2016 yet.

As L2 VM, a minimal debian 8 installs and boots without problem (didn't try networking yet).

Kernel 4.10.x and qemu-kvm 2.9 required?

Don't forget to :
- enable nested hardware-assisted virtualization (https://pve.proxmox.com/wiki/Nested_Virtualization),
- set CPU type to "host" for your L1 guest

Some known issues are being worked on (notably NIC can't be Intel e1000 at this time but VirtIO is OK) :
