I recently installed a Windows 10 VM under oVirt 4.4.5.11-1.el8 Also installed the drivers using "virtio-win-1.9.16.iso" (Then re-installed them after updates just in case it helped)
I found a similar complaint with VMWare (https://communities.vmware.com/t5/VMware-Workstation-Pro/vmware-workstation-100-disk-usage/td-p/2704870) So I looked into that and made a registry change for the AHCI controller, as well as setting the 'viodiskcache' to write-back (Seen in another thread on here) - those two changes seemed to help.. marginally. But not much at all. When I do just about anything, disk usage spikes to 100% and stays there for quite a while. Write speeds rarely break 100kb/sec. Not even sure what to look for next. My Linux VMs don't seem to have this issue and the host it's running on is barely working at all. CPU and memory stay close to unused. oVirt didn't show a lot, but in task manager in the Windows VM - you can see disk queue just pegged completely. I've given the VM 6GB of RAM, so that's not it. I even turned off paging in the Windows VM as well, to no avail. This is an example of disk usage, just opening 'Groove Music' for the first time. https://i.postimg.cc/FRLq28Mw/Disk-Activity.png Any ideas? :) _______________________________________________ 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/TL7ADS2SY6VJE3MUCT3FJTCCGK6CEKPX/
