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

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 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...

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.
