2021.08.03 KVM IOPS limit

  • total_iops_sec
    The optional total_iops_sec element is the total I/O operations per second. This cannot appear with read_iops_sec or write_iops_sec.
    <disk type='block' device='disk'>
      <driver name='qemu' type='raw' cache='none' io='native'/>
      <source dev='/dev/VolG00/hogeimage'/>
      <target dev='vda' bus='virtio'/>
      <alias name='virtio-disk0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/>
      <iotune>
        <total_iops_sec>100</total_iops_sec>
      </iotune>
    </disk>

OpenNebulaでテンプレート以外で変更する場合

テンプレートでIO制限が設けられているが、すでに作成済みのVMのディスクIO制限を変更する場合

VM停止後、vm_poolのbodyを書き換えてあげる。

下記を追加
