We have an existing cluster of VMware ESXi and XenServer 6 and 7 hypervisors, running multiple Lunix and Windows VMs of various vintages.
We plan to migrate all the VMs to Proxmox on new hardware, using ZFS replication to give us failover and HA. For the more modern Linux VMs this seems straightforward, export from ESXi as OVF, load into Proxmox, and off they go. However we have some aged internal VMs which refuse to boot, seems to be Grub related and none of the solutions I've found so far work, so we were thinking of just running an ESXi VM within Proxmox and then the old VMs under that, and possibly doing the same with a XenServer VM too.
The existing ESXi hardware are Dell C6100 blades with twin Xeon processors with up to 24 cores per blade, and Virtualisation switched on in the BIOS.
The new Proxmox machines are 120 core monsters with 377 gig of memory, and lscpu reports:
Model name: Intel(R) Xeon(R) CPU E7-4880 v2 @ 2.50GHz
Virtualization: VT-x
The problem: When I attempt to boot an successfully imported VM unde the vitrtual ESXi, I get an error "This host does not support Intel VT-x"
The ESXi VM was set up with OS Type “Other OS Types“, CPU Type “host“, Network Type “VMWare vmxnet3“.
What do I need to do to enable the ESXi VM to see the VT-x on the Proxmox host?
