Hi, I am trying to get the CPU utilization of a node and I am using virNodeGetCPUStats(...) Here is my code snippet. The error checking is omitted for brevity. /* get the number of params */ retval = virNodeGetCPUStats (conn, VIR_NODE_CPU_STATS_ALL_CPUS,\ NULL, &nparams, 0); printf ("nparams: %d\n", nparams); /* allocate space for the params */ params =

Hi, I am facing issue with the calls getCPUStats and getMemoryStats. Please find the error below. AttributeError: 'module' object has no attribute 'VIR_NODE_CPU_STATS_ALL_CPUS' >>> print con.getCPUStats(2, None, 0, 0) Traceback (most recent call last): File "<stdin>", line 1, in <module> File

Hi. Since the update to libvirt-1.3.2, virsh keeps disconnecting from qemu:///session. Weirdly enough, qemu:///session works fine for root, and qemu:///system works for both the user and the root. With the same configuration(tarball with files from /etc/libvirt attached), libvirt-1.3.1 works without problems. From the virsh debug log(attached): --- grep error virsh.log.1.3.2 2016-03-03

Dear all, I have installed DRBD 8.3.11 compiled from sources. However the backend block will freeze if there is high IO load. I use Remus to support high availability and checkpointing is controlled by remus for each 400ms. If I check the Iostat I got the idle CPU will decreasing extremely each checkpointing and when its reach 0% of idle cpu the local backing device will freeze and damage the

Hi Dave, I built successfully an xvm 3.3 system. However, I found virt-manager and virt-install don''t work. I attached the error messages of both as below. xm tool seems to work. I can run OpenSolaris200811 LiveCD and install it onto file based disk. The error messages of virt-manager: ====start of error message==== Unable to open connection to hypervisor URI ''xen'':

I did some additional testing - I stopped Kafka on the host, and kicked off a disk check, and it ran at the expected speed overnight. I started kafka this morning, and the raid check's speed immediately dropped down to ~2000K/Sec. I then enabled the write-back cache on the drives (hdparm -W1 /dev/sd*). The raid check is now running between 100000K/Sec and 200000K/Sec, and has been for several

Hi all, I've got some problems to make work oVirt. I've installed a Fedora 10 VM the lightest possible (nothing checked, even based) and installed after some packages (wget, sudo, acpid,...) and updated the system. By the way, acpid should be a dependency of ovirt-installer because the installation fails if it's not available. I've then installed ovirt (ovirt-server-installer

Issue: Vista reads slowly from a samba server. This appears to pop up periodically here and elsewhere. My samba.conf file has: [homes] ... vfs objects = readahead As suggested elsewhere. Writes are approximately 17-18MB/s which is acceptable. Reads are in the 8MB/s range which is appalingly slow. Using linux smbclient and windows XP clients I can read at 25+MB/s. I've enabled vfs

It was found that the software NIC team created in Centos was having issues due to a failing network cable. The team was going berserk with up/down changes.

Hopefully I summed up the jist of the problem in the subject line. ;) I have a GFS cluster with ten Xen 3.0 dom0s sharing an iSCSI LUN. There are on average 8 domUs running on each Xen server. The dom0 on each server is hard-coded to 2 CPUs and 2GB of RAM with no ballooning, and has 2GB of partition-based swap. When creating a new domU on any of the Xen servers, just after the completion of

All of our Kafka clusters are fairly write-heavy. The cluster in question is our second-heaviest ? we haven?t yet upgraded the heaviest, due to the issues we?ve been experiencing in this one. Here is an iostat example from a host within the same cluster, but without the RAID check running: [root at r2k1 ~] # iostat -xdmc 1 10 Linux 3.10.0-327.13.1.el7.x86_64 (r2k1) 05/27/16 _x86_64_ (32 CPU)

Hey! I have a strange condition in one of the servers that I don't where to start looking. I login to the server via SSH (cant doit any other way) and anything that I type is slow HTTP sessions timeout waiting for screen redraw. So, the server is acting "slow". server is bare metal. no virtual services. no alarms in the disk raid note: server was restarted because of power failure.

Hi. I entered one of our domU tonight and see following problem: # iowait -k 5 avg-cpu: %user %nice %system %iowait %steal %idle 0.00 0.00 0.00 100.00 0.00 0.00 Device: tps kB_read/s kB_wrtn/s kB_read kB_wrtn sda1 0.00 0.00 0.00 0 0 sda2 0.00 0.00 0.00 0

We are struggling with a strange problem. When we have some VMWare clients running (mostly MS windows clients), than the IO-write performance on the host becomes very bad. The guest os's do not do anything, just having them started, sitting at the login prompt, is enough to trigger the problem. The host has plenty of 4G of RAM, and all clients fit easily into the space. The disksystem is a

I?ve posted this on the forums at https://www.centos.org/forums/viewtopic.php?f=47&t=57926&p=244614#p244614 - posting to the list in the hopes of getting more eyeballs on it.

Hello, We have a 5 node OCFS2 volume backed by a Sun (Oracle) StorageTek 2540. Each system is running OEL5.4 and OCFS2 1.4.2, using device-mapper-multipath to load balance over 2 active paths. We are using the default multipath configuration for our SAN. We are observing iowait time between 60% - 90%, sustaining at over 80% as I'm writing this, driving load averages to >25 during an rsync

Hi, I'm able to get the CPU utilization metrics from libvirt for the guests (VM's) remotely . Is it possible to get the Host Cpu stat's through libvirt ? I didn't find any information regarding the host cpu cycles and memory utilization to collect them remotely. Libvirt is installed on all the hosts.

Folks, At what point in iowait should I start to worry about having a bottleneck, or is this something that can't be answerd with a single integer? According to sar, after my last reboot to turn off hyperthreading as a test, at one time, I see 4.9% iowait, but then one minute later, it droped back to 0.01%, and rarely even gets to 1.0%, at least what I remember from yesterday. ?
