I doubt it. More likely you are having problems from trying to use your i386 system on an amd64 kernel, which will be looking in a different place for the i386 libraries. > next reboot >=20 > now >=20 > zfs import -R /mnt -f tank >=20 >=20 > and it's waiting forever. doing nothing, both CTRL-C and CTRL-Z doesn't= =20 > work. >=20 > it's doing nothing as i see that qemu uses almost no CPU.

That's not what copies is supposed to be used for.
