So, what you might notice if you try to load up one of the latest OSes as a guest in Kimchi is that you get an error.
“Error KCHIMG0001E while creating template: “physical block size is 2048 bytes, but Linux says it is 512 bytes.”
Thankfully, this is a quick fix and already patched but not yet in stable as of the time of this writing.
Here is where the issue is discussed, and the patch can be found in this commit:
https://github.com/kimchi-project/kimchi/commit/1ec059af4040c50b1a7b9a34253510a46ca09d3b
Once you apply the patch appropriately and restart wokd, Kimchi should work appropriately.
