[libvirt] Is virConnectListDefinedDomains broken?
Hi, list, Recently, I upgraded my system to Xen 3.3.1 (from Xen 3.0.3). After this, I found that virConnectListDefinedDomains no longer works. The problem can be reproduced by executing "virsh list -all" - those defined but inactive domains are not be returned. Has libvirt API been tested against Xen 3.3.1? Can this problem be fixed by upgrading libvirt to version 0.6.5? What is the best approach to address this issue? Thanks in advance, Eddy OS: CentOS 5.3 Xen: kernel-xen.x86_64 2.6.18-128.1.14.el5 installed kmod-drbd83-xen.x86_64 8.3.0-3 installed xen.x86_64 3.3.1-0 installed xen-libs.x86_64 3.3.1-0 installed libvirt: libvirt.x86_64 0.4.4-3 installed libvirt-python.x86_64 0.4.4-3 installed python-virtinst.noarch 0.300.2-12.el5 installed virt-viewer.x86_64 0.0.2-2.el5 installed

In Xen <= 3.0.x inactive domain configs are not managed by XenD at all, so libvirt has some hacky code to read files in /etc/xen. In Xen >= 3.1.0 XenD has proper management APIs for inactive guests and libvirt uses that instead. So if you upgrade from 3.0.x to > 3.1.x then any config files in /etc/xen should be loaded into XenD using 'xm new CONFIG'. libvirt will then be able to see & manage them properly Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
