KVM over KVM- Openstack
I hope this is a simple question.
I've installed OpenStack following the official guide for Juno. All the 6 nodes(Controller, compute, network object storage 1/2 and bloq storage) are Virtual Machines of the same server(its a quite powerfull server) virtualized with KVM.
Now, i want to use KVM on the compute node for the instances of openstack, is this possible?
I'm asking this because instances wont boot using KVM, but they will if I use QEMU.
Edit:
Aditional info:
Compute node(L1):
lsb_release -a (all the nodes)
Distributor ID: Ubuntu
Description: Ubuntu 14.04.2 LTS
Release: 14.04
Codename: trusty
lsmod | grep kvm_intel
kvm_intel 143590 0
kvm 452088 1 kvm_intel
$ file /dev/kvm
/dev/kvm: character special
$ cat /sys/module/kvm_intel/parameters/nested
Y
Host server(L0):
lsb_release -a
Distributor ID: Ubuntu
Description: Ubuntu 14.04.2 LTS
Release: 14.04
Codename: trusty
$ cat /sys/module/kvm_intel/parameters/enable_shadow_vmcs
Y
$ cat /sys/module/kvm_intel/parameters/enable_apicv
Y
$ cat /sys/module/kvm_intel/parameters/ept
Y
$ cat /sys/module/kvm_intel/parameters/nested
Y
This is what happens when i launch an instance with virt_type= KVM

Which OS you running on VMs ?
Hi, when virt_type on nova-compute.conf is set to kvm, and i try to boot an instance qemu-system-x86 takes 100% of the cpu, cpus "allocated" by the instance will stuck (sometimes
CPU#0 stuck for 22s!
shows)Which OS you running on VMs ?
Which OS you running on baremetal ?
What kind of Virtualization you use on baremetal ?
I edit my question , everything use Ubuntu 14.04, baremetal virtualization -> kvm (qemu-kvm) i manage the vms with the virt-manager
VFS: cannot find ext4 file system is system error having nothing in common with virt_type nova settings
