High SPM cpu load during RHEV-M storage manipulation on RHEV 3.3
Issue
- When issuing a vm snapshot remove, the SPM machine (after some minutes) gets a very high cpu load
- VMs on the same hypervisor seem to suffer from the complete cpu utilization by the SPM operation making vms slow and unresponsive
- During the snapshot deletion,
qemu-kvmprocesses may also show high CPU usage, even though their hosted guest is idle.
Environment
- Red Hat Enterprise Virtualization (RHEV) 3.3
