Looks like @yann experinced the same error trying to create a VM whose size is smaller than the VM’s rootfs size
app: Error importing root volume (but VM created): Data import failed: not enough data (copied 771339878 bytes, expected 10737418240 bytes)
The solution they posted was
dd if=/dev/zero of=myrootfs.img count=0 bs=1 seek=10737418240
But im not sure how to include the above dd with the qvm-create command?
Do i just add it to the end?
