Description of problem:


Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. install 2 virtual machines using Fedora18 netinstall.iso. Select minimal install
2. on both system add ovirt repository. (sudo yum localinstall http://ovirt.org/releases/ovirt-release-fedora.noarch.rpm)
3. on first VM install ovirt-engine
4. on second VM install vdsm and vdsm-hook-faqemu. Configure enable fake_kvm_support in /etc/vdsm/vdsm.conf
5. add host in oVirt Engine Web Administration

  
Actual results:
in the events are these errors:
Host ovirt-node installation failed. Command returned failure code 1 during SSH session 'root.1.70'.
Failed to install Host ovirt-node. Failed to execute stage 'Setup validation': [Errno 5] Input/output error.

Host status is: Install Failed

Expected results:

Hi,

can you please archive in tar all the /dev/cpu/*/msr files and attach?

Thanks!

Thanks but this is not good, as you archived the actual device instead the content.

You need to take caution... perform cat /dev/cpu/0/msr and attach the result.

Thanks!

Hi, I did it but there is no result. It show nothing. "cat /dev/cpu/0/msr" command is running forever. Maybe rdmsr from msr-tools can help.

Hi,
here is the output.

Thanks!
Before we debug this python farther, can you please install msr-tools package and send the output of:
# rdmsr 0x3a

Hi,

[root@ovirt-node ~]# rdmsr 0x3a
rdmsr:pread: Input/output error
Comment 10 Alon Bar-Lev 2013-03-03 15:28:35 UTC 
Haim,

Do we have "Intel Core 2 Duo P9xxx (Penryn Class Core 2)" board?
Comment 11 kissi7 2013-03-03 16:13:37 UTC 
Hi Alon,

just to make sure... as I already mentione both machines are virtual. With standard QEMU cpu I was not able to add host to ovirt (same error). Than I change virtual CPU via virt-manage to "Intel Core 2 Duo P9xxx (Penryn Class Core 2)" by clicking on Copy Host CPU configuration" but the result is same. 

If you run your msr.py or rdmsr 0x3a on any KVM machine with "QEMU Virtual CPU version (cpu64-rhel6)" you should receive same error as I.
Comment 12 Alon Bar-Lev 2013-03-03 16:24:52 UTC 
Oh!!!
I did not understand these machine are virtual!
Then this must a bug in qemu environment.
Now it makes more sense.
OK, I will just ignore this error and warn user.
Thanks!

Comment 14 Alon Bar-Lev 2013-03-06 19:46:58 UTC 
I am unsure this worth issue in 1.0.1 as this is nested virtualization.
Comment 15 Itamar Heim 2013-09-23 07:35:31 UTC 
closing as this should be in 3.3 (doing so in bulk, so may be incorrect)
