HI! What hardware configuration you use for ceph? I use 4 server + 4 HP D2700. Have 36 SAS drives. 10Gb Network.
Read/Write speed = 1200/350 MB/s. In Windows VM write speed = 45MB/s. Add more drives not speed up. This is unacceptable for cloud.
Thanks!
Make sure you’re using virtio for the disks in the windows VM. Set device prefix to ‘vd’ in the VM template. You’ll then need to install the windows virtio drivers available from the fedora project.
In addition if you are using Centos7 try qemu-kvm-ev from the oVirt repo. And as addition try to enable ‘virtio-blk data plane’. But with the 'qemu-kvm-ev" I can’t achieve remarkable additional performance gain by enabling it. (you can enable the feature by adding an “XML tweaking script” in the remotes/vmm/kvm/deploy script, just before the XML is passed to virsh)
