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, 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

Hi, I'm trying to figure out what controls the number if in-flight virtio block operations when running linux in qemu on top of a linux host. The problem is that we're trying to run as many VMs as possible, using ceph/rbd for the rootfs. We've tripped over the fact the the memory consumption of qemu can spike noticeably when doing I/O (something as simple as "dd" from

Hi, is there a way to configure blkio via libvirt (xml)? Regards Erkan -- ?ber den grenzen mu? die freiheit wohl wolkenlos sein

Hi all, is there a way to limit the throughput (or the number of operations per seconds) of a block device? I ask because I've a couple of misconfigured VMs that are performing a lot of disk activity (swapping I'd bet but I haven't access to their OS). Since their storage is on a NFS share they are slowing down other VMs on the same share. Thank you. Davide.

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

WHY CentOS still using qemu-kvm 0.12? What I am need is high version of qemu-kvm for CentOS, but seems like they do not officially provide newest qemu, only qemu 0.12 source code with 3522 patched rpm package. Is there any reasonable to keep low version for qemu-kvm ? or what should I do if I need newest qemu-kvm rpm package? ✉ -- 朴元奎 kerwin

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

Centos is not going to generally have the cutting edge stuff. For that why not try fedora which will generally package with the newest libraries from various packages, including qemu . I think the current fedora repos have qemu 2.1 > On Jul 6, 2014, at 10:01 AM, kerwin <piaoyuankui@gmail.com> wrote: > > WHY CentOS still using qemu-kvm 0.12? > > What I am need is high

Hi all, I use libvirt-go in my agent to attach rbd volumes. I ofen suffer the issue of incosistent of domain dump xml and domain persistent xml file. For example, when I try to attach volume, the the domain by ?virConnectListAllDomains? api from libvirt tell me the vdf or 0x0a is empty, but when attach it with the vdf device or 0x0a address, qemu return the error duplicated with vdf or PCI

Hi list, i tried to write my first type and provider that should create logical volumes.

With distros it's always a question of stability vs bleeding edge. It's not possible to have git builds every day and

I'm trying to set up a 2nd DC.  The primary is a Server 2003 (ads1).  But DNS is being done on a Linux proxy server.  It appears that I have joined correctly (wbinfo -t: checking the trust secret for domain SAMDOM via RPC calls succeeded).  But when I check inbound and outbound (samba-tool drs showrepl) I get the following: > Default-First-Site-Name\ATHENA > DSA Options: 0x00000001

What does the mount log say when you get the EIO error on snooper? Check if there is a gfid mismatch on snooper directory or the files under it for all 3 bricks. In any case the mount log or the glustershd.log of the 3 nodes for the gfids you listed below should give you some idea on why the files aren't healed. Thanks.
