The parameters I used in the virt-install command above are intentional, and I tried to steer you around several issues that you could run into. boot cdrom,hd,menu=on -noautoconsole -force disk pool=$disk_pool,size=900,sparse=true,bus=ide,format=qcow2 # even though disk is sparse, takes a couple of minutes to create # use pool that has enough capacity for sparse 900Gb $ qemu-system-x86_64 -net nic,model=? | grep vmxnet3 # verify that 'vmxnet3' is valid NIC type # ESXi 7 has a stricter compatibility list Run the ‘virt-install’ command below, tailoring it to any specific cpu/disk/ram requirements and use a virsh pool capable of handling a 900Gb sparse drive. Now we are ready to create a KVM virtual machine capable of running ESXi. # want Y to be returnedĬat /sys/module/kvm/parameters/ignore_msrsĬat /sys/module/kvm_intel/parameters/enable_apicvĬat /sys/module/kvm_intel/parameters/nestedĬat /sys/module/kvm_intel/parameters/ept Create KVM Virtual Machine for ESXi Reboot the host, then login and run the following commands. Then in order to workaround an issue with Ubuntu, force the value for ignore_msrs echo 1 | sudo tee /sys/module/kvm/parameters/ignore_msrs Options kvm_intel nested=1 enable_apicv=0 ept=1 options kvm ignore_msrs=1 report_ignored_msrs=0 In the file “/etc/modprobe.d/nf”, set the following lines. In addition to enabling VT-x at the BIOS level, you will also need to configure it at the Ubuntu OS level. We cannot created a nested virtualization solution without this support. Each BIOS is different but look for “Virtualization Technology” or “VT-x”. If you do not have this enabled, reboot your machine and press the special function key (F1|F2|F10|DEL|ESC|alt-S) that takes you into the BIOS.

You need to make sure your CPU is capable of VT-x (virtualization acceleration), and then that your BIOS has VT-x enabled. I am assuming you are running Ubuntu and have already installed and smoke tested KVM as described in my previous article. VMware vSphere Hypervisor ESXi is a commercial product, but when you create an account and start an evaluation period, you can download a 60 day trial.Ĭlick on the section “Download the hypervisor (vSphere ESXi Installable)” and then download the “VMWare vSphere Hypervisor (ESXI ISO) Image”. On top of that I will create a KVM virtual machine that runs VMware ESXi.įinally, we will run a smoke test by deploying a guest OS in the nested ESXi. In this article, I’ll be using a bare metal server running Ubuntu and KVM as a type 1 hypervisor. Luckily, if you need to test something specific to VMware you can always run ESXi 7.0 nested inside a KVM virtual machine. If you are running KVM on an Ubuntu server, you already have an excellent Type 1 virtualization engine.
