Hi all, I'm running a VM using libvirt+KVM and I have a disk performance issue. The host is the following: 4 cores Intel Xeon 5140@2.33 GHz, 16 GB of RAM, SATA HDD, OS Debian Wheezy, libvirt 0.9.12-11, QEMU-KVM 1.1.2+dfsg-2. The guest: 1 CPU, 2 GB RAM running Debian 7.0, image in compressed qcow2 format. When I try do run "dd if=/dev/zero of=io.test bs=32768k count=40" I get

Hi again! Need to add here, since I been investigating a bit further, that it seems to be possible to add an NPIV vhba to the guest, using vdsm hooks. I've seen the reference to "host device assignments", which Dan pointed me too, but I didn't really understand the meaning of it at that moment. It would be interesting to hear from someone that have been doing it, how it would

Well, it's not possible, at least for me. This is as far as I got, any help

Hi List, I have used XML in R version 2.9.2. The code is working fine using Rv2.9.2 and its related XML package. Now I am using Rv2.13.1 and its related XML package, but I get the following error: Error in UseMethod("xmlName", node) : no applicable method for 'xmlName' applied to an object of class "NULL" Any idea? Thanks Arvin [[alternative HTML version

Hi All, I am setting the value for "read_bytes_sec" using the following API code virDomainSetBlockIoTune(dom, "/mnt/tmpsdb/FileVM1", parainfoPtr, nparams, 2); I am succesfully able to set this value and i can read it back using the API virDomainGetBlockIoTune(dom,"/mnt/tmpsdb/FileVM1",parainfoPtr,&nparams,2); But after setting this value when i shutdown

Hi, I am running OpenStack Cluster and use libvirt + cgroup to limit vm’s performance https://wiki.openstack.org/InstanceResourceQuota What I am confusing is.. 1. After running a vm instance with some croup limit applied, I can’t find any related cgroup settings. 2. Can I change limit value after instance is running? like change disk_read_iops_sec from 10 to 20. One of the xml file like below.

Hi, reading the below[1] on blkdeviotune made me wonder if we can dynamically change the values after the VM is already running using iotune. Is it supported? Thanks, Doron [1] https://fedoraproject.org/wiki/QA:Testcase_Virtualization_IO_Throttling

Yes. 'virsh blkdeviotune' will do it (which makes calls to the underlying virDomainSetBlockIoTune() API). -- Eric Blake eblake redhat com +1-919-301-3266

Hi, John, and thank you! This was a very thorough and welcome response, I was wondering where all the storage guys were... I will get back to you with more details later, specifically about multipath, since this needs to be investigated thoroughly. I have, with trial and error method, during the elapsed time, been able to attach the NPIV pool LUN to a virtio-scsi controller, and it seems it
