The dmidecode problem really only affects those three machines I'm
trying to set up as ovirt hosts. Since I couldn't find anything
wrong in the CentOS setup I tried Fedora 22 and got the same result.
/dev/mem: Operation not permitted
I'm sorry to have bothered you guys with this problem that is
obviously not ovirt related. I'll try to find a solution and keep
you posted.
All the best
Richard

dmidecode always fails and according to the things I've read
this is
caused by the kernel restricting access to /dev/mem. But this
shouldn't affect the root user. It does anyway. I've tried with=
selinux on and off. Is there a way around this problem? So
far =
I
didn't find anything really helpful by googling around.
This
problem
seems only to affect these kind of machines. CentOS 7.1
installations with the same kernel on another machine lets
me run
dmidecode without problems. I guess I'm missing something.

[root@cube-one tmp]# dmidecode

[root@cube-one tmp]# /usr/sbin/dmidecode -s system-uuid
/dev/mem: Operation not permitted

dmidecode -s system-uuid is failing cause it cannot read /dev/mem so
VDSM fails getting the host UUID and so vdscli raise an exception
about a None value on 'uuid' when hosted-engine
calls getVdsCapabilities.
Any hint on that or any workaround?
