[ovirt-users] Re: Terrible Disk Performance on Windows 10 VM

This is a simple one desktop setup I use at home for being a nerd :) So it's a single host 'cluster' using local storage. Host Info: CentOS Linux 8 - 4.18.0-305.10.2.el8_4.x86_64 (I keep fairly well updated) Intel(R) Core(TM) i5-7500 CPU @ 3.40GHz [Kaby Lake] {Skylake}, 14nm The disk it's on is: WDC WD40EZRZ-00G (5400 RPM platter disk) - it's not the fastest thing in the world, but it should be sufficient. VM info: Windows 10 Professional (Desktop not server) 6144 MB of RAM 2 Virtual CPUS - Some settings I ran across for 'Performance' mode and a couple I had seen on some similar issues (the similar issues were quite dated) Running in headless mode I/O Threads enabled = 1 Multi-Queues enabled Virt-IO-SCSI enabled Random Number generator enabled Added a custom property of 'viodiskcache' = writeback (Didn't seem to make any significant improvement) As I type this though - I was going to add this link as it's what I followed to install the storage driver during the Windows install and then in the OS after that: https://access.redhat.com/solutions/17463 I did notice something.. it says to create a new VM with the 'VirtIO disk interface' and I just noted my VM is setup as 'SATA'. Perhaps that is it. This is just my first attempt at running something other than a Linux Distro under oVirt. When I first installed the Windows guest, I didn't have the Virt-IO package downloaded initially. When Windows couldn't find a storage driver, I found this info out. I think I'll deploy a new Windows guest and try the 'VirtIO-SCSI' interface and see if my performance is any better. It's just a default install of Windows at this point, so that'll be easy. :) Will update this thread either way!
