[libvirt] [PATCH 0/4] Support for SPICE graphics
by Daniel P. Berrange 28 Oct '09

28 Oct '09

This series of patches adds minimal support for SPICE graphics which is newly introduced in RHEL-5.4's fork of KVM. Since this is not yet merged in upstream QEMU/KVM, I'm not proposing to merge all these patches. The two XML schema patches are straightforward to merge. The two implementation ones are RHEL5 specific and I want to avoid declaring them supported until we have a sign of what the upstream merge will look like, since previous attempst to support KVM args prior to QEMU acceptance have been very painful long term.

[libvirt] [PATCH] libvirt-devel should only require libvirt-client
by Mark McLoughlin 28 Oct '09

28 Oct '09

There's a long known issue where if you install libvirt in a guest, the default virtual network will conflict with the default virtual network in the host. That's one of the reasons we have the libvirt-client RPM - it allows you to install the client library without having the host side installed. Rich Jones points out that if you install libvirt-devel in a guest, then you get libvirtd installed and the network conflict: https://bugzilla.redhat.com/531200 libvirt-devel should only require libvirt-client - e.g. nothing in the devel package pertains to anything in the libvirt RPM. The Fedora packaging guidelines say: https://fedoraproject.org/wiki/Packaging/Guidelines#Devel_Packages Devel packages must require the base package using a fully versioned dependency ... But for all intents and purposes, libvirt-client is our base RPM. * libvirt.spec.in: make libvirt-devel require libvirt-client --- libvirt.spec.in | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/libvirt.spec.in b/libvirt.spec.in index 6cd0888..7e1550e 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -341,7 +341,7 @@ virtualization capabilities of recent versions of Linux (and other OSes). %package devel Summary: Libraries, includes, etc. to compile with the libvirt library Group: Development/Libraries -Requires: libvirt = %{version}-%{release} +Requires: libvirt-client = %{version}-%{release} Requires: pkgconfig %if %{with_xen} Requires: xen-devel -- 1.6.2.5
