Dell PowerEdge Systems Red Hat Enterprise Linux 8 Release Notes
Guest VMs with SRIOV VFs assigned take a long time to power on, and libvirt related errors are observed
- Description
- On a system with multiple guest VMs running storage I/O and network IO operations, VMs with SRIOV VFs assigned take a long time to power on. When the issue occurs, following error message is logged in /var/log/messages continuously until the guest VM successfully powers on:
Timed out during operation: cannot acquire state change lock (held by monitor=remoteDispatchDomainCreate)
- Cause
- By default, the cache setting for VMs is set to write back. This results in host memory being used for buffer cache when storage I/O is being performed by guest VMs.
- Solution
- Modify the cache setting for guest VMs to none. For more information, see
Red Hat Enterprise Linux Knowledge Base article 5886891.
In the XML profile of guest VMs, change the following:
<disk type='file' device='disk'> <driver name='qemu' type='qcow2'/>To<disk type='file' device='disk'> <driver name='qemu' type='qcow2' cache='none'/> - Systems affected
- All Dell EMC PowerEdge servers
- Applies to
- Red Hat Enterprise Linux 8.3
