[Bug 1810400] Re: Failed to make dirty bitmaps writable: Can't update bitmap directory: Operation not permitted

[John Snow]

Hi, this should be fixed in 4.2. It looks like you're still on 2.12.0
based on the report. Closing under the assumption this is fixed. If you
discover otherwise, please feel free to re-open (or file a new bug.)

** Changed in: qemu
       Status: Confirmed => Fix Released
