Hi, Guys Recently I am investigating the Optimization Policy in Cluster and try to use “ CPU Threads ”. As the manual of description: For example, a 24-core system with 2 threads per core (48 threads total) can run virtual machines with up to 48 cores each My host CPU is i3-2120 CPU (2 cores 4 threads) So I think the expect result case is : 1. If the “ Count Threads As Cores ” disable , we can’t run virtual vm with above 2 vCPU 2. If the “ Count Threads As Cores ” enable , we can’t run virtual vm with above 4 vCPU Now the problem is about result case 1: 1. When I set “ Count Threads As Cores ” disable , I still can run virtual vm with 4 vCPU Can anyone help me to explain it ??? Like Artyom mentioned, it best to see your lscpu output but my guess is that the 4 threads is actually 2 per core. And there are 2 core and 2 sockets. this means 4 cpus without hyper threading and 8 with. BTW the Host General subtab on the webadmin should output all this info as well. Check it out.

[ovirt-users] ovirt 3.5.2 issues with nodes becoming Non Operational
Hi, I'm new to oVirt and recently built a 10 node ovirt 3.5 DC with shared storage using gluster configured as distributed-replicated (replication = 2). Shortly after 7 of the 10 nodes dropped, one at a time over a few hours, into Non Operational state. Attempting to activate one of these nodes gives the error: Failed to connect Host ovirt-node260 to Storage Pool LADC-TBX. Attempting to put the node into Maintenance eaves the node stuck in Preparing For maintenance. When I rebooted one of the nodes I see this in the nodes event list: Host ovirt-node269 reports about one of the Active Storage Domains as Problematic. I see many of these errors in the vdsm log from the failed nodes: Thread-1::ERROR::2015-08-12 10:01:17,748::__init__::506::jsonrpc.JsonRpcServer::(_serveRequest) Internal server error Traceback (most recent call last): File /usr/lib/python2.6/site-packages/yajsonrpc/__init__.py, line 501, in _serveRequest res = method(**params) File /usr/share/vdsm/rpc/Bridge.py, line 267, in _dynamicMethod result = fn(*methodArgs) File /usr/share/vdsm/API.py, line 1330, in getStats stats.update(self._cif.mom.getKsmStats()) File /usr/share/vdsm/momIF.py, line 60, in getKsmStats stats = self._mom.getStatistics()['host'] File /usr/lib/python2.6/site-packages/mom/MOMFuncs.py, line 75, in getStatistics host_stats = self.threads['host_monitor'].interrogate().statistics[-1] AttributeError: 'NoneType' object has no attribute 'statistics' Any help here is appreciated. -- Chris ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [ovirt-users] ovirt 3.5.2 issues with nodes becoming Non Operational
I may have figured this out. The systems that failed are running the Oracle unbreakable kernel: 3.8.13-98.el6uek.x86_64 The working systems are running the default CentOS 6 2.6 kernel. and the error from the vdsm.log only show up on the UEK kernel. -- Chris On Wed, Aug 12, 2015 at 9:34 AM, Chris Liebman chri...@taboola.com wrote: Hi, I'm new to oVirt and recently built a 10 node ovirt 3.5 DC with shared storage using gluster configured as distributed-replicated (replication = 2).
