Hi

It seems that OpenNebula cannot detect the hypervisor you are using. Could
you send us the output for:

  • (If you are using KVM) lsmod | grep kvm
  • (if you are using Xen) ls /proc/xen/capabilities

Thanks

Hi, output of lsmod | grep kvm is empty because all options related to kvm and visualization are compiled in kernel.

CONFIG_KVM=y
CONFIG_KVM_INTEL=y
# CONFIG_KVM_AMD is not set

Thanks
Martin

I’m afraid that we didn’t consider that case.

I’ll file an issue for this, meantime you can just go to
/var/remotes/vnm/ovswtich and:

  • Update post to read:
    ovs = OpenvSwitchVLAN.from_base64(template64, deploy_id, “kvm”)

  • Update clean to read:
    ovs = OpenvSwitchVLAN.from_base64(template64,"-",“kvm”)

After that, run onehost sync as oneadmin from the front-end

Thanks

Ruben

Yes, this is a workaround. VM starts and joins virtual bridge as expected.
