I created a snapshot of a virtual machine. The VM runs fine. But when I
went to run the snapshot, I got the following error:
Error starting domain: internal error: process exited while connecting

I had previously gotten an error on the permissions of a storage file
(?) in the same directory, debian-testing-amd64-netinst.1774376356. It
had been 0600; I changed it to 0644 and that at least lead to the
current error.
Directory permissions are drwxrwxr-x or drwxr-xr-x all the way up and
all are owned by root:root.

Does anybody read signatures any more?
