When trying to make a snapshot on a VM, the VM hangs undefinitely. I have this in logs:
mars 08 09:34:55 onexgsh015 libvirtd[2480]: 2018-03-08 08:34:55.309+0000: 2487: warning : qemuDomainObjBeginJobInternal:3827 : Cannot start job (query, none) for domain one-4749; current job is (async nested, snapshot) owned by (2484 remoteDispatchDomainSnapshotCreateXML, 2484 remoteDispatchDomainSnapshotCreateXML) for (1426s, 1426s)

Same error if I try to resume the VM:
[root] # virsh resume 261
erreur :Timed out during operation: cannot acquire state change lock (held by remoteDispatchDomainSnapshotCreateXML)
I’m pretty sure it was working long time ago.
However the disk snapshot are working fine.
Any idea ?
OpenNebula 5.4.8 on CentOS 7.
Best regards,
