How to optimally deploy a virtual machine with .ova configuration on a server with hyper-v?

Question

virtual box

There is a server on WS 2012 Datacenter, which hosts virtual machines on hyper-v. You need to deploy another virtual machine. There is its configuration in a file with the .ova extension under VirtualBox
. Since two hypervisors on the same host machine are not friendly, I created another virtual machine with WS 2008R2, installed VirtualBox on it, but it did not want to work as the virtual machine does not support VTX . Although I read somewhere that the WS2012 hypervisor allows you to run the hypervisor on a virtual machine (I don’t remember the link) I
also thought about converting the machine to hyper-v, but after reading that this could lead to malfunctions of the converted machine, I didn’t dare
Please tell me possible solutions to the problem

Answer 1

OVA is a VMware format rather. Inside there is usually .vmdk (disk) and .ovf (virtual hardware configuration description).
You need the contents of the disk, and you can create a virtual machine by hand. VirtualBox allows you to convert a vmdk disk to vhd format, which you can then slip into Hyper-V. OVA is a tar archive. Unpack it with tar, extract the vmdk and convert it using VBoxManage to .vhd:
VBoxManage clonehd --format vhd disk1.vmdk disk1.vhd
Then manually create a virtual machine on Hyper-V and slip this vhd into it.
