I'm doing some testing on one of the Linaro build machines and I reliably see
Summary of Failures:
712/790 qemu:block / io-qcow2-150 ERROR
5.24s exit status 1
777/790 qemu:block / io-qcow2-copy-before-write ERROR

This is x86_64 ubuntu 22.04, same as my laptop, so the only thing I can think is the
filesystem type:
hackpool-0/home/richard.henderson /home/richard.henderson zfs
rw,nosuid,nodev,noatime,xattr,noacl 0 0
Any thoughts?
