[libvirt-users] error: internal error: Unable to parse 'rbps=max wbps=max riops=100 wiops=max' as an integer

[Oliver Dzombic]

Hi,

i am running:

libvirt-5.6.0-5.fc31.x86_64
5.4.8-200.fc31.x86_64


Using:

  <blkiotune>
    <device>
      <path>/dev/sda1</path>
      <read_iops_sec>100</read_iops_sec>
      <write_iops_sec>100</write_iops_sec>
      <read_bytes_sec>51200000</read_bytes_sec>
      <write_bytes_sec>51200000</write_bytes_sec>
    </device>
  </blkiotune>


and receiving

error: internal error: Unable to parse 'rbps=max wbps=max riops=100
wiops=max' as an integer

when i try to start it.

I found on Redhat Bugzilla a case that claims that its solved by

Fixed In Version: 	libvirt-5.6.0-3.el8

While i am running 5.6.0-5.

Maybe its simply because the cgroup v1 is not correctly mounted:

# mount | grep cgroup
cgroup2 on /sys/fs/cgroup type cgroup2
(rw,nosuid,nodev,noexec,relatime,nsdelegate)

# cat /proc/self/cgroup
0::/user.slice/user-0.slice/session-1.scope


But i didnt find anything how to activate that properly.

I would be thankful for any suggestions.

Thank you!
