Error external "exception 80000004" with some installer in Win11 VM

General

Hi,
since the last upgrade, I get the error “external exception 80000004” in every Windows 11 VM, 23h2 and 24h2, with some installers. The same VMs with identical Libvirt configuration on Kubuntu 24.10 on the same hardware, does not have the problem.
Since QEMU was updated during the upgrade, I suspect this as a possible cause.
For example CrystalDiskMark can’t be installed under CachyOS, but no problem under Kubuntu

Why not? How are you installing it?

3

is that supposed to be funny?
double click, then the error appears immediately

I was under the assumption that CrystalDiskMark was a Linux program, I guess not.

When you say this, do you mean that the configuration files were copied over? Since there is a one major version difference between Arch’s and Ubuntu’s libvirt, that may not work.

only the CPU, clock and feature part, it worked until last week
The default config for Win11 has the same issue under CachyOS
