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 frees most of their cache.Sadly without cache performance will drop , but you can't assign unlimited memory :D Best Regards, Strahil Nikolov В неделя, 29 ноември 2020 г., 10:57:00 Гринуич+2, Stefan Seifried <s.seifrie...@gmail.com> написа: Hi, I'm quite new to oVirt, so my apologizies if I'm asking something dead obvious: I noticed that there is an item in the 'General Tab' of each VM, which says 'Guest OS Memory Free/Cached/Buffered' and on all my VM's it says 'Not Configured'. Right now I'm trying to figure out how to enable this feature. I assume that this gives me the equivalent output of executing 'free' on the shell on a Linux guest. Googling and digging around the VMM guide did not give me any pointers so far. Thanks in advance, Stefan PS: A little background info: I have one 'client' which keeps nagging me to increase the RAM on his VM because it's constantly operating at 95% memory load (as shown on the VM dashboard). After a quick investigation with 'free' I could see that Linux has built up the disk cache to 12G (from 16G total, no swapping occured). My intention is to make the real memory load visible to him, as he has already access to the VM portal for shutdown/restart/etc. _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/4IBDDFYNKD7PESO7BTR66SZRGQTSXCVD/ _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/VF7C4IQE4RBQ4YW75DQNDRSIP5TRKGKA/
