currently, I create a cluster with Conroe family. My host/node works. And I can create some VMs on it. But I am not sure if the issue talking here will impact the VM's performance? Or stability ?
performance only, and mostly for guests utilizing new westmere features. i think this patch was around this not sure if its in 4.10.0-7.fc17 or a new issue commit 498d1dd6f01a7f5488792c41f73f7cca57b2c890 Author: Gal Hammer <gham...@redhat.com> Date: Mon Jun 4 17:55:35 2012 +0300 BZ#737104 Disallow cross-vendor virtualization. Find vendor for all cpu models, including those based on another cpu module.

I am trying to install the ovirt on my Xeon E5-2650 process on Dell server, which is installed with Fedora 17. While I create a new host , which actually is the same server as overt-engine is running. The host is created ,and starting to "installing". But it ends with "Non operational state". Error: Host CPU type is not compatible with cluster properties, missing CPU feature: model_sandybridge. But in my cluster, I select "sandybridge" CPU, and my Xeon C5 is also in Sandy bridge family. And also this error lead my serverreboot.Any help is appreciated. Btw: I have enable INTEL-VT in BIOS. And modprobe KVM and kvm-intel modules. . attached is screen shot for error. _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/usersplease send output of this command from the host (not engine) vdsClient -s 0 getVdsCaps | grep -i flags_______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
