Something I've seen recommended is to under-provision (during partitioning) the SSD; any way to force the UTM installer to do that?
It appears it is possible, at least on the software installation image.
During the install (Alt-F2 at the Introduction screen), edit /etc/bootstrap/l/default.xml to alter the partitioning parameters: size(s) and factor (appears to be percentage guidance). Alt-F1 to return to the installer Introduction screen and proceed.
After the filesystems are formatted and the rpm package installation begins the partitioning can be checked with parted. For /dev/sda, "parted /dev/sda print".
