Package: qemu-kvm
Version: 0.11.1+dfsg-1
Severity: wishlist
Unless you want to do something really magic[1], you almost certainly
don't want to use kvm to boot a mounted filesystem. This can cause
filesystem corruption. Please consider having kvm detect mounted
filesystems and refuse to boot them. To handle those magic cases, offer
an option -force-mounted or similar to override that detection.
I've done this myself (realized halfway through a Debian install onto a
USB drive via debian-installer in KVM that I left the USB drive booted),
and I've also had to explain how to check for mounted partitions before
booting them with kvm. A bit of DWIM seems helpful.
[1] Like mounting GFS2 or another multi-mount filesystem, or booting
your main disk and carefully not booting the running system's root
filesystem...
