I was going to post this as a patch, but I realize the patch is just working around an actual bug in the libvirt backend [not in libvirt]. Anyway, posting it here so we don't forget about it. Rich.

This is not useful. You need to do something like: exec /usr/libexec/qemu-kvm -s

New option -compat lets you configure what to do when deprecated interfaces get used. This is intended for testing users of the management interfaces. It is experimental. -compat deprecated-input=<in-policy> configures what to do when deprecated input is received. Available policies: * accept: Accept deprecated commands and arguments (default) * reject: Reject them * crash: Crash

...new enough" qemu. As a special case you can also do ‘./configure --without-qemu’ (or ‘./configure --with-qemu=no’ which is the same thing) which disables qemu, although that means for libguestfs to work at all you would need to supply a qemu binary at runtime through an environment variable (‘LIBGUESTFS_HV=/path/to/qemu program’). The logic for all this is here: https://github.com/libguestfs/libguestfs/blob/master/m4/guestfs_qemu.m4#L26 > I would like libguestfs to take even the "qemu-img" binary from the > installed qemu package. > How to enable that? qemu is a hypervisor, q...

...loader opening the 170+ libraries that qemu is linked to (×2 because we need to run qemu twice). Fixing that is seriously hard work. Therefore memoize the results of guestfs_int_test_qemu. This is keyed on the size and mtime of the qemu binary, so if the user changes the qemu binary (eg. setting LIBGUESTFS_HV) we discard the memoized result and rerun the qemu commands. There is also a generation number so we can bump the generation in future versions of libguestfs to invalidate all previously cached data. The memo is stored in the supermin cache directory (eg. /var/tmp/.guestfs-*) in the files: qem...

From: "Richard W.M. Jones" <rjones at redhat.com> This means there will be no default hypervisor, and effectively the user will always have to specify one (eg. by setting LIBGUESTFS_HV or calling guestfs_set_hv). This is useful on platforms where qemu doesn't work, or where qemu is not needed (eg. if you want to use UML, or you just want to compile libguestfs without using/testing it). --- configure.ac | 125 ++++++++++++++++++++++------------------- src/h...
