Thanks, I will play around a little with the settings.
The VM is a build agent so disk caching is not too much of a concern. I
originally started with only 4GB of memory and build times only slightly
improved with 16GB (104 minutes to 100 minutes).
Thanks Liran, that issue fits my problem indeed.
Installing ovirt-guest-agent on the older VM's (CentOS 7) did the trick.
However, on a CentOS 8 (Kernel 4.18) + qemu-guest-agent (2.12.0) the values
still do not show. But maybe the guest agents are still too old.
Hi Stefan,
you can control the VM's cache (if Linux) via:
- vm.vfs_cache_pressure
- vm.dirty_background_ratio/vm.dirty_background_bytes
- vm.dirty_ratio/vm.dirty_bytes
- vm.dirty_writeback_centisecs
- vm.dirty_expire_centisecs
I would just increase the vfs_cache_pressure to 120 and check if it
Hi Stefan,
Please check out https://bugzilla.redhat.com/1884050 if it fits your
problem.
The resolution was having the right guest-agent installed in the
guest(qemu-guest-agent or ovirt-guest-agent).
