tried all the solutions provided on the internet

On the controller node the scheduler_default_filters is set to AllHostsFilter. libvirt_type=qemu in nova.conf file installed nova-compute-qemu package on the compute node.

but nothing worked.

Hi Ranjit.

ls -l shows /dev/kvm file belongs to group kvm. But still no luck. xxxxx@compute1:~$ ls -l /dev/kvm crw-rw----+ 1 root kvm 10, 232 May 2 10:54 /dev/kvm

After taking Ranjit's suggestion and restarting nova services in compute node it worked.

see the link textfor troubleshooting . For help, i just copy and paste the required info.

Troubleshoot KVM

Trying to launch a new virtual machine instance fails with the ERRORstate, and the following error appears in the /var/log/nova/nova-compute.log file:

libvirtError: internal error no supported architecture for os type 'hvm'

This message indicates that the KVM kernel modules were not loaded.

If you cannot start VMs after installation without rebooting, the permissions might not be correct. This can happen if you load the KVM module before you install nova-compute. To check whether the group is set to kvm, run:

ls -l /dev/kvm

If it is not set to kvm, run:

udevadm trigger
