KVM builds (Early Access)¶
To make use of this, your derivation must have
kvm listed in its
attribute. If a derivation is not marked with
kvm, nixbuild.net will not
activate KVM support and
/dev/kvm will not be available to the build.
Additionally, you must configure your nix client to send
kvm builds to
nixbuild.net. This is done by adding the
kvm tag to the list of system
features for the remote builder:
eu.nixbuild.net x86_64-linux - 100 1 big-parallel,benchmark,kvm,nixos-test
Above, we also added the
nixos-test feature which is needed if you want to
build NixOS integration tests.
KVM builds are only supported on
The support for KVM builds in nixbuild.net is a new feature that still is in development and therefore you need to request access to it by contacting [email protected]. During the Early Access period, KVM builds are priced and invoiced exactly the same as standard builds When the KVM support has been finalized and made available to everyone, the pricing and price model might look different.
The KVM support in nixbuild.net was announced in this blog post.
