This was not planned for this weekend, but having to reboot my #homelab main machine, I decided to upgrade the installed #debian from bookwork to trixie.
Reading the known issues made me resize the /boot partition before said upgrade. Thanks to the #gparted live CD and my #jetkvm I did it remotely without any issue.
The upgrade after that was also smooth. My only issue was to get my #Windows10 VM to boot, but even that was solved, by pointing to the correct #ovmf file.

I'm trying to make my #QEMU #VM resilient against software that tries to detect it's running inside of a VM. Seems like I have to do a lot to make this work. Like changing QEMU and #OVMF #source #code. Currently I'm trying to remove the detectable overhead of executing the instructions RDTSC -> CPUID -> RDTSC in sequence. Which results in a much longer delay within VMs.

I need a way to dump .fd files, i.e. ovmf.fd from qemu/TianoCore
I will fall back to booting Linux in QEMU or finding some UEFI mode tool.

so i've moved my macos #kvm to its own nvme. what was much snappier on the sata ssd, in the qemu image than on baremetal nvme windows is now even better. however this thing was advertised to 7k MB/s read ..it is not quite there. due to apfs i am not sure how to verify this test right now. using virtio-blk because i was unable to passthrough the nvme controller – not even manually. (unviable group, even when forced to #vfio module)
lets see if i can tweak it a bit – suggestions welcome #ovmf
