The best approach would be: qvm-run --pass-io tempDebian 'tar -Scf - /home/user/meta.raw' > meta.tar and then untar the resulting file Almost anything else (dd, rsync etc) will have some overhead in my experience. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

[qubes-users] Problems with qvm-run --pass-io
Hi, I tried to copy a raw image for a metasploitable vm to dom0, but it doesn't work. I followed the instructions on https://www.qubes-os.org/doc/ hvm/#converting-virtualbox-vm-to-hvm to create the raw image, then I tried to copy it to dom0: [robert@dom0 ~]$ qvm-run --pass-io tempDebian 'cat "/home/user/meta.raw"' > > /var/lib/qubes/appvms/metasploitable/root.img > I stopped the command with Ctrl+C, because the root.img became bigger than the original file's size.
