It's erms, which is there. But it's not the culprit.
Sorry if you have already tested it, but have you tried using 7.2 kernel
with QEMU 2.6, and then 7.3 kernel with QEMU 2.3? That would allow
finding the guilty component more easily.
Thanks,
No problem.
- 7.3 kernel with qemu 2.3 seems ok
It is the configuration used for deploying self hosted engine vm
[root@ovirt41 ~]# rpm -q qemu-kvm-ev

[root@ovirt41 ~]# uname -r
3.10.0-514.el7.x86_64

( it seems it is the 7.3 kernel, based on

- So I have to try the mix of 7.3 kernel and qemu 2.6, correct?
Perhaps it was a problem only during install and not happening now that the
VM has been deployed?
