VMware ESXi is an operating system-independent hypervisor based on the VMkernel operating system interfacing with agents that run atop it.
At work, we use VMware ESXi to host the VMs but I run VirtualBox on my development machine. Luckily, fine folks at Oracle thought of this and make it quite easy.
Step 1)
Export ESXi VM to a single OVF (Open Virtualization Format) file.
Step 2)
File->Import Appliance
Then select
3) Fix the VT-x is disabled in the BIOS (VERR_VMX_MSR_VMXON_DISABLED) problem
When powering on the imported VM, you may run into the VT-x disabled problem.
To fix, let’s turn off the I/O APIC (Advanced Programming Interrupt Controller)
Select “System”, and uncheck “Enable I/O APIC”
After this change, I can start my imported VM just fine.
