Currently libvirt requires two qemu derivations: qemu and qemu_kvm which is just a truncated version of qemu (defined as qemu.override { hostCpuOnly = true; }).
This patch exposes an option virtualisation.libvirtd.qemuPackage which allows to choose which package to use:
* pkgs.qemu_kvm if all your guests have the same CPU as host, or
* pkgs.qemu which allows to emulate alien architectures (for example ARMV7L on X86_64), or
* a custom derivation
virtualisation.libvirtd.enableKVM option is vague and could be deprecate in favor of virtualisation.libvirtd.qemuPackage, anyway it does allow to enable/disable kvm.
The program `qemu-img` is needed during creation of virtual machines
with qcow2 images. Otherwise creation of such VMs (e.g. with
virt-manager) are failing.
Fixes issue with virt-manager failing to list 'USB Host Devices' and
'PCI Host Devices' with the error "Connection does not support host
device enumeration".
Modifies libvirt package to search for configs in /var/lib and changes
libvirtd service to copy the default configs to the new location.
This enables the user to change e.g. the networking configuration with
virsh or virt-manager and keep those settings.
Upstream bug: https://bugzilla.redhat.com/show_bug.cgi?id=1293060
This patch is based on the one attached to that bug report, but
instead of patching the .x files (parsing of which apparently
fails as well) it modifies the pre-generated .c files directly.
This ought to fix#12139.
Previously, the native libvirt package was making an assertion that
the dependent Python package had a compatible version. This commit
switches that so that the Python package makes the assertion, since
it makes more sense to me to have a child package making an
assertion about its parent than vice versa.
