So, can you start it again when libaio1 is NOT installed? Note that after you remove a library - any library - applications linked against it will continue running just fine. You wont be able to start new applications linked to this library, -- that's for sure, but already running will continue, since the library will still be in memory and on disk (but deleted). >> None of qemu-system or qemu-user binaries are linked with libaio. >> libaio1 is not used and hence not needed. >> >> Note that qemu package - against which you filed the bugreport - >> is a meta-package, it does not use any library at all. > > # aptitude why qemu > i xen-qemu-dm-4.0 Depends qemu-system | qemu qemu depends on qemu-system. I don't know what xen-qemu-dm-4.0 uses for its qemu component. I think it too comes with integrated qemu, just another variant of it (like qemu-kvm is yet another variant). > # aptitude why libaio1 > i libvirt-bin Recommends qemu-kvm | qemu (>= 0.9.1) > p qemu-kvm Depends libaio1 So libaio1 is used only by qemu-kvm (correctly), not by any other installed packages. Which is exactly what I tried to say initially. > Maybe qemu is not the right package, then which is the right pkg? I dunno - in particular, I don't know how xen uses qemu and if it uses its own copy or not. I can _guess_ this dependency is only for some support files, not for qemu-system binaries, but that's just a guess. >>> On KVM systems this is not >>> a problem because its a dependency of qemu-kvm.

I guess qemu-system is also useless, if not some support files included in there. >> xen-qemu-dm* packages are not relevant for qemu. >> >> Please describe your issue in a bit more details.

Especially since you're having issue with xen which - most likely - does not use separate qemu package at all.
