So, my previous set of patches for inactive domain management deal with the problem for Xen 3.0.3 or earlier. In 3.0.4 we now have lifecycle management support, which means we no longer need to scan /etc/xen config files if running against a new XenD. We choose between Xend & scanning /etc/xen files based on the condition 'xendConfigVersion >= 3'. The attached patch adds 5 new entry points to xend_internal.c xenDaemonListDefinedDomains xenDaemonNumOfDefinedDomains xenDaemonDomainCreate xenDaemonDomainDefineXML xenDaemonDomainUndefine These let you enumerate inactive domains, define new ones, delete old ones. Secondly, the patch modifies a number of existing methods to work against inactive domains too. Previously they'd unconditionally pass if the domain id was < 0. Now, if xendConfigVersion is >= 3, then they will know that XenD supports inactive domains & thus work for inactive guests too. xenDaemonDomainGetMaxMemory xenDaemonDomainSetMaxMemory xenDaemonDomainSetMemory xenDaemonDomainGetInfo xenDaemonDomainSetVcpus xenDaemonDomainDumpXML The methods for setting mem,max memory & vcpu count all required further bug fixes to Xend which have been sent upstream & hopefully merged soon. Finally, the patch changes the xendConfigVersion to be lookedup just once when initially connecting to XenD. Since we need this version info very frequently now, it was causing too much unnneccessary overload calling it every time. internal.h | 1 xend_internal.c | 270 +++++++++++++++++++++++++++++++++++++++++++++----------- xend_internal.h | 8 + xm_internal.c | 9 - 4 files changed, 227 insertions(+), 61 deletions(-) Regards, 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 -=|
