[...] I hit this problem too. The current versions of virt-manager, libvirt, etc. in unstable do work. But I recognise that this is still a kernel bug that needs to be fixed (particularly for stretch-backports). Ben. -- Ben Hutchings Computers are not intelligent.

We did it once before and it caused a regression (bug #880471). So, before we enable it again someone will need to investigate and check that the regression won't happen again.

Bug#742619: linux: Please reenable CONFIG_SCSI_PROC_FS
Please re-consider the "wontfix" decision. This makes it impossible to use LTO tape drives on Debian, and it forced me to install CentOS on the machine controlling the tape loader, when all my other Linux machines are Debian. Mi
