Hi, It appears that scsi_debug needs actual memory when creating the virtual disks. If I run the tests inside a qemu VM with just 512MB of RAM, the t3200-type-change test fails when it tries to create a 550MB virtual disk.
Most of the other tests get by with virtual disks of just a few megabytes. Would someone who understands the partition structure better than me be able to change the numbers so the test runs with a 10MB disk? Cheers, Ross
