But when I create a new VM, i had an error

Sat Apr 9 00:44:25 2016 : No system datastore meets capacity and SCHED_DS_REQUIREMENTS: CLUSTER_ID = 100 & !(PUBLIC_CLOUD = YES)

Whats wrong?

hi, the datastore Cephds is not assigned to a cluster yet.
(see top right button: “Select Cluster”) So the scheduler cannot use the datastore.

Sorry, i uploaded miss screen)

got this from another forum, not sure if it will help…

The error could not find capabilities for domaintype=kvm is
indicative of the lack of kvm support on the host. It may mean that the
kvm/kvm_intel/kvm_amd modules aren’t loaded, the CPU doesn’t support
hardware virtualisation, or the required options are disabled in the
BIOS.

Unfortunately, but it does`t solve problem.

There are 4 servers:

  • KVM-ADMIN with ceph-deploy
  • KVM-1, KVM-2 KVM-3 with OpenNebula sunstone + kmv-node package. (Like this manual)
  • MySQL Galera Cluster for OpenNebula
  • pacemaker, corosync & crmsh for High Available.
  • CephRBD

I mounted /var/lib/one/ from KVM-1 to other hosts.
Create cluster with all KVM hosts and all Storages including CephRBD.

I try to restart livbritd. Check all privileges. All mounts works. Hosts available for each other.
I cant understand what the problem.

This is the error from libvirt

Tue May 31 12:44:47 2016 [Z0][VMM][I]: error: недопустимый аргумент: could
not find capabilities for arch=x86_64 domaintype=kvm

It seems that your nodes are not x86_64 capable. Execute virsh capabilities
in the nodes to see the available architectures…

Problem solved.
After BIOS firmware upgrade, option Intel-VT was reset.
Now that`s OK.

p.s. Sometimes it is necessary to pay attention to details)
