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.

Sorry for the late reply.

Define: local.

NFS, Gluster or ISCSI?

- Gilboa

 

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!
