Yeah, that's a bug in libvirt - we failed to tear down the 'still born' domain when something goes wrong during creation. > If the <currentMemory> tag is suppressed from the XML configuration file, > all is OK. Sounds like a bug in Xen ia64 to me - the <currentMemory> is used to set the initial boot RAM, while the <memory> tag is used to set the maximum reservation. If you omit <currentMemory> then both will be set to the same value. It sounds like Xen ia64 is not able to cope with the memory < maxmem situation. memory=200 maxmem=500 > This behaviour appears with the libvirt version 0.1.8 released with the > RHEL5 RC, and also with the libvirt version 0.1.10. > Are you aware of this problem? No - we don't do much (any) testing on ia64 due to lack of any suitable hardware for testing, so we pretty much rely on community/vendors to identify ia64 problems. > If you want some complementary infos (xend log), we can send it to you. See if you can reproduce it with a regular Xen config file using config options like memory=200 maxmem=500 Which should simlute presece of '<currentMemory>' element. If you can reproduce it there, its a Xen bug.
