Azure Fabric runs on a customized version of Hyper-V, it appears. Is it possible to run a KVM virtualized instance on Azure (using nested virtualization)?
I have a custom VHD which is based on Debian (say). Based on this document https://learn.microsoft.com/en-us/azure/virtual-machines/linux/create-upload-generic, it seems that it might be possible, if the Hyper-V drivers are built into the kernel.
Has anyone run successfully run a KVM instance on Azure? If so, could you please share your experience.
This is possible, but you need to select either a Dv3 or Ev3 series VM. Also, based on my knowledge, Windows VMs are not supported, Linux VMs are supported.
First you need to install kvm and virt-manager.
apt-get update
apt-get install kvm qemu-kvm libvirt-bin virtinst
apt install virt-manager
adduser `id -un` libvirt
adduser `id -un` kvm
You also need to config the NIC like below: vi /etc/network/interfaces
iface br0 inet static
address 192.168.0.100
network 192.168.0.0
netmask 255.255.255.0
broadcast 192.168.0.255
gateway 192.168.0.1
bridge_ports eth0
bridge_fd 9
bridge_hello 2
bridge_maxage 12
bridge_stp off
Restart the NIC by using /etc/init.d/networking restart.
Now, you could create a VM by using
virt-install --connect qemu:///system -n vm10 -r 512 --vcpus=2 --disk path=/var/lib/libvirt/images/vm10.img,size=12 -c /dev/cdrom --vnc --noautoconsole --os-type linux --os-variant debiansqueeze --accelerate --network=bridge:br0 --hvm
You could check the VM's status by using virsh -c qemu:///system list, you will get like below:
root@shui:~# virsh -c qemu:///system list
Id Name State
