This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --SnfbGmQB2OdmgSIlGKsUrHrnPCD7QGuje Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable 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 On 09/01/2015 11:14 AM, Simone Tiraboschi wrote:

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. =20 [root@cube-one tmp]# dmidecode # dmidecode 2.12 # SMBIOS entry point at 0xbafbaca0 /dev/mem: Operation not permitted =20 [root@cube-one tmp]# /usr/sbin/dmidecode -s system-uuid /dev/mem: Operation not permitted =20 =20 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? =20 [root@cube-one tmp]# grep DEVMEM /boot/config-3.10.0-229.11.1.el7.x86_64 CONFIG_STRICT_DEVMEM=3Dy =20 Cheers Richard =20 -- /dev/null =20 =20 =20
