[libvirt] [PATCH] Refactor the libvirt RPM daemon pieces
From: "Daniel P. Berrange" <berrange@redhat.com> NB: this is in response to a Fedora 17 beta blocker bug. Currently gnome-boxes depends on 'libvirt' which pulls in the default virtual network, which kills networking if you install Fedora 17 inside a KVM guest. There are a number of flaws with our packaging of the libvirtd daemon: - Installing 'libvirt' does not install 'qemu-kvm' or 'xen' etc which are required to actually run the hypervisor in question - Installing 'libvirt' pulls in the default configuration files which may not be wanted & cause problems if installed inside a guest - It is not possible to explicitly required all the peices required to manage a specific hypervisor This change takes the 'libvirt' RPM and and changes it thus - libvirt: just a virtual package with dep on libvirt-daemon and libvirt-daemon-configs - libvirt-daemon: the libvirt daemon and related pieces - libvirt-daemon-configs: the default network & filter configs - libvirt-docs: the website HTML We then introduce some more virtual (empty) packages - libvirt-daemon-qemu: Deps on libvirt-daemon & 'qemu' - libvirt-daemon-kvm: Deps on libvirt-daemon & 'qemu-kvm' - libvirt-daemon-lxc: Deps on libvirt-daemon - libvirt-daemon-uml: Deps on libvirt-daemon - libvirt-daemon-xen: Deps on libvirt-daemon & 'xen' - libvirt-qemu: Deps on libvirt-daemon-qemu & libvirt-daemon-configs - libvirt-kvm: Deps on libvirt-daemon-kvm & libvirt-daemon-configs - libvirt-lxc: Deps on libvirt-daemon-lxc & libvirt-daemon-configs - libvirt-uml: Deps on libvirt-daemon-uml & libvirt-daemon-configs - libvirt-xen: Deps on libvirt-daemon-xen & libvirt-daemon-configs My intent in the future is to turn on the driver modules by default, at which time 'libvirt-daemon' will cease to include any specific drivers, instead we'll get libvirt-daemon-driver-XXXX packages for each driver. The libvirt-daemon-XXX packages will then pull in each driver that they require. It is recommended that applications required a locally installed libvirtd daemon, use either 'Requires: libvirt-daemon-XXXX' or 'Requires: libvirt-XXX' and *not* "Requires: libvirt-daemon" or 'Requires: libvirt' * libvirt.spec.in: Refactor RPMs * docs/packaging.html.in, docs/sitemap.html.in: Document new RPM split rationale --- docs/packaging.html.in | 100 ++++++++++ docs/sitemap.html.in | 4 + libvirt.spec.in | 474 +++++++++++++++++++++++++++++++++++------------- 3 files changed, 456 insertions(+), 122 deletions(-) create mode 100644 docs/packaging.html.in diff --git a/docs/packaging.html.in b/docs/packaging.html.in new file mode 100644 index 0000000..2e4abf7 --- /dev/null +++ b/docs/packaging.html.in @@ -0,0 +1,100 @@ +<?xml version="1.0"?> +<html> + <body> + <h1>Distribution packaging</h1> + + <ul id="toc"></ul> + + <p> + This page describes the rationale behind the libvirt distribution +packaging in RPM format.

NB: this is in response to a Fedora 17 beta blocker bug. Currently gnome-boxes depends on 'libvirt' which pulls in the default virtual network, which kills networking if you install Fedora 17 inside a KVM guest.
There are a number of flaws with our packaging of the libvirtd daemon:
- Installing 'libvirt' does not install 'qemu-kvm' or 'xen' etc which are required to actually run the hypervisor in question - Installing 'libvirt' pulls in the default configuration files which may not be wanted & cause problems if installed inside a guest - It is not possible to explicitly required all the peices required to manage a specific hypervisor
This change takes the 'libvirt' RPM and and changes it thus
- libvirt: just a virtual package with dep on libvirt-daemon and libvirt-daemon-configs - libvirt-daemon: the libvirt daemon and related pieces - libvirt-daemon-configs: the default network & filter configs - libvirt-docs: the website HTML
We then introduce some more virtual (empty) packages
- libvirt-daemon-qemu: Deps on libvirt-daemon & 'qemu' - libvirt-daemon-kvm: Deps on libvirt-daemon & 'qemu-kvm' - libvirt-daemon-lxc: Deps on libvirt-daemon - libvirt-daemon-uml: Deps on libvirt-daemon - libvirt-daemon-xen: Deps on libvirt-daemon & 'xen'
- libvirt-qemu: Deps on libvirt-daemon-qemu & libvirt-daemon-configs - libvirt-kvm: Deps on libvirt-daemon-kvm & libvirt-daemon-configs - libvirt-lxc: Deps on libvirt-daemon-lxc & libvirt-daemon-configs - libvirt-uml: Deps on libvirt-daemon-uml & libvirt-daemon-configs - libvirt-xen: Deps on libvirt-daemon-xen & libvirt-daemon-configs
My intent in the future is to turn on the driver modules by default, at which time 'libvirt-daemon' will cease to include any specific drivers, instead we'll get libvirt-daemon-driver-XXXX packages for each driver. The libvirt-daemon-XXX packages will then pull in each driver that they require.
It is recommended that applications required a locally installed libvirtd daemon, use either 'Requires: libvirt-daemon-XXXX' or 'Requires: libvirt-XXX' and *not* "Requires: libvirt-daemon" or 'Requires: libvirt'
I'm not an RPM wizard, so I cannot evaluate the changes, but ACK to the design, I think it's a great change. Dave

NB: this is in response to a Fedora 17 beta blocker bug. Currently gnome-boxes depends on 'libvirt' which pulls in the default virtual network, which kills networking if you install Fedora 17 inside a KVM guest.
There are a number of flaws with our packaging of the libvirtd daemon:
- Installing 'libvirt' does not install 'qemu-kvm' or 'xen' etc which are required to actually run the hypervisor in question - Installing 'libvirt' pulls in the default configuration files which may not be wanted & cause problems if installed inside a guest - It is not possible to explicitly required all the peices required to manage a specific hypervisor
This change takes the 'libvirt' RPM and and changes it thus
- libvirt: just a virtual package with dep on libvirt-daemon and libvirt-daemon-configs - libvirt-daemon: the libvirt daemon and related pieces - libvirt-daemon-configs: the default network & filter configs
It occurs to me that we perhaps ought to split the configs into two pieces too. The Xen and UML drivers only support the network driver, so they don't need the network filter configs The OpenStack NOVA project does not want the default NAT network, but it does want the network filter configs. So I'm thinking instead of libvirt-daemon-configs, create: - libvirt-daemon-config-network - libvirt-daemon-config-nwfilter Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|

We then introduce some more virtual (empty) packages

My intent in the future is to turn on the driver modules by default, at which time 'libvirt-daemon' will cease to include any specific drivers, instead we'll get libvirt-daemon-driver-XXXX packages for each driver. The libvirt-daemon-XXX packages will then pull in each driver that they require.
I like the modularity of this package setup. There is one difference with the change described in the final paragraph, though, that will cause some surprises when it's done: With the current setup, you can install the "libvirt" package, and it will just use/present whichever hypervisors happen to be installed on the machine. With the new setup, if you have qemu-kvm and lxc installed on the machine, then install "libvirt", you won't get the libvirt driver for either of these - you'll need to explicitly install libvirt-qemu and libvirt-lxc. This may cause surprises for people who already have bootstraps that just install "qemu-kvm" and "libvirt". Is there a way within the package system to specify something like "If package X is installed, then also require package libvirt-X"?
It is recommended that applications required a locally installed libvirtd daemon, use either 'Requires: libvirt-daemon-XXXX' or 'Requires: libvirt-XXX' and *not* "Requires: libvirt-daemon" or 'Requires: libvirt'

NB: this is in response to a Fedora 17 beta blocker bug. Currently gnome-boxes depends on 'libvirt' which pulls in the default virtual network, which kills networking if you install Fedora 17 inside a KVM guest.
There are a number of flaws with our packaging of the libvirtd daemon:
- Installing 'libvirt' does not install 'qemu-kvm' or 'xen' etc which are required to actually run the hypervisor in question - Installing 'libvirt' pulls in the default configuration files which may not be wanted & cause problems if installed inside a guest - It is not possible to explicitly required all the peices required to manage a specific hypervisor
This change takes the 'libvirt' RPM and and changes it thus
- libvirt: just a virtual package with dep on libvirt-daemon and libvirt-daemon-configs - libvirt-daemon: the libvirt daemon and related pieces - libvirt-daemon-configs: the default network & filter configs - libvirt-docs: the website HTML
We then introduce some more virtual (empty) packages
- libvirt-daemon-qemu: Deps on libvirt-daemon & 'qemu' - libvirt-daemon-kvm: Deps on libvirt-daemon & 'qemu-kvm' - libvirt-daemon-lxc: Deps on libvirt-daemon - libvirt-daemon-uml: Deps on libvirt-daemon - libvirt-daemon-xen: Deps on libvirt-daemon & 'xen'
- libvirt-qemu: Deps on libvirt-daemon-qemu & libvirt-daemon-configs - libvirt-kvm: Deps on libvirt-daemon-kvm & libvirt-daemon-configs - libvirt-lxc: Deps on libvirt-daemon-lxc & libvirt-daemon-configs - libvirt-uml: Deps on libvirt-daemon-uml & libvirt-daemon-configs - libvirt-xen: Deps on libvirt-daemon-xen & libvirt-daemon-configs
My intent in the future is to turn on the driver modules by default, at which time 'libvirt-daemon' will cease to include any specific drivers, instead we'll get libvirt-daemon-driver-XXXX packages for each driver. The libvirt-daemon-XXX packages will then pull in each driver that they require.
I like the modularity of this package setup. There is one difference with the change described in the final paragraph, though, that will cause some surprises when it's done:
With the current setup, you can install the "libvirt" package, and it will just use/present whichever hypervisors happen to be installed on the machine. With the new setup, if you have qemu-kvm and lxc installed on the machine, then install "libvirt", you won't get the libvirt driver for either of these - you'll need to explicitly install libvirt-qemu and libvirt-lxc. This may cause surprises for people who already have bootstraps that just install "qemu-kvm" and "libvirt".
No, that's not the case. The behaviour of 'yum install libvirt' is identical before & after. You won't get the 'libvirt-daemon-kvm' package installed, but that's fine, because that's an empty virtual package.

Yes, this is to let us deal with RHEL where we only provide qemu-kvm, not the rest of the TCG based binaries.

I don't think there's a good way todo it in two separate steps - in fact it would likely make it even harder to ensure a correct upgrade paths.

This may cause surprises for people who already have bootstraps that just install "qemu-kvm" and "libvirt". No, that's not the case. The behaviour of 'yum install libvirt' is identical before & after. You won't get the 'libvirt-daemon-kvm'

That will be the case with the current changes, but will it still be true even after we switch to providing a separately compiled module for each hypervisor driver? (that's actually the case I was thinking about, not the current case)

Okay. BTW, you've probably already fixed it, but I just found that packaging.html fails to validate (haven't investigated, since it's very likely you already encountered it too)

Oh right, yes. What will happen is that 'libvirt-daemon' will not pull in any drivers, but for back compat 'libvirt' will still pull in all driver modules. This is why the docs recommend people to dep on 'libvirt-daemon-qemu' instead of relying on 'libvirt-daemon' to pull in qemu.

Yep, thanks for mentioning it. Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|
