I have move a Win10 KVM guest to new hardware and than upgrade this guest to
Windows 11.
[..]
4x qemu64 CPU (1 Socket/ 4 Core/ 1 Threads)
8GB RAM
No graphic tablet
No Ballon driver
When I copy a big file (~8GB) from Network to local I get 1 GBit/s speed.
When I run to install RSAT tools or ClearMgr I only see 10-25 MB/s in iostat
on the KVM host.
Any ideas or suggestions?
The disk use Virtio driver with no buffer and unmap.
Three ideas:
1. Check the status of the virtual drive from Windows point of view:
Open the “Optimize Drives” application and verify that the
Media type equals “Thin provisioned device” (it should say that).
2. `qemu64` may be an inadquate choice of CPU.
See <
https://www.berrange.com/posts/2018/06/29/cpu-model-configuration-for-qemu-kvm-on-x86-hosts/>
for some ideas about what to chose instaed. Note that it may
cause issues with Windows Activation i.e. if you don't have
the necessary data at hand, maybe don't just change it on a
whim.
3. Does the VM behave notably slower than a comparable reference
system?`I am asking because IMHO it may very well be a reasonable
IO throughput for a Windows OS and maybe there is nothing out of
the ordinary I/O-wise here?
For comparison, I ran the `cleanmgr` and deleted about 4 GiB of
files from my Windows 11 VM just now and it never exceeded ~9 MiB/s
(measuring in 10sec intervals I got 90 MiB/interval)
on the host averaging much below.
