[Libvir] [Patch 0/4] Xen inactive domain
by Daniel P. Berrange 03 Sep '06

03 Sep '06

The following series of patches add support for managing inactive domains with Xen. Based on DV's recent xm config file reader, it processes all domains in /etc/xen (skipping known bogus files, xmexmaple*, xend-config.sxp). It can do all the operations you'd expect for managing inactive domains. Create a new domain, start a domain, list domains, delete a domain, change cpu / memory, get XML for domain. The impact on existing driver backends is very small - the only place which needed changing is the XenD code which lookups existing domains - making it be quiet if it get s a 404 error from XenD - this is to be expected if the domain is inactive.

[Libvir] Semantics for ListDomains/ ListDefinedDomains
by Daniel P. Berrange 03 Sep '06

03 Sep '06

So I was thinking a little about lifecycle support for passive domains in libvirt and wanted to clarify the intended semantics of the two methods: virConnectListDomains virConnectListDefinedDomains Am I correct in thinking that virConnectListDefinedDomains will list a domain if-and-only-if its state == 'shutoff', and that virConnectListDomains will list a domain if-and-only-if its state != 'shutoff' ie, when I start a defined domain with 'virDomainCreate', it will be removed from the 'ListDefinedDomains' set and added to the 'ListDomains' set. Likewise when shutting down it'll move back the other way. Or will the virConnectListDefinedDomains call always list a domain with a config file, even if it is running ? I realize this is a little hypothetical since XenD doesn't have lifecycle management yet, but it matters to the test backend, and any potential QEMU / UML backend, and the future XenD XML-RPC backend Dan. -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=|

[Libvir] Libvirt / Xen incompatible versions.
by Michel Gauthier 01 Sep '06

01 Sep '06

We've just installed the last advanced version of Xen on our IA64 platform. Unfortunatly, the build of the 0.1.4 version of libvirt with this version of Xen is not successful. The C header file of Xen /usr/include/xen/dom0_ops.h used by libvirt in xen_internal.c has been modified. The dom0_getdomaininfo_t structure is no more decared in this header file. Are you aware of this problem? What is the latest version of Xen on which libvirt has been successfully built and tested? Thanks.
