There another problem when you make the libvirt src on the arch of itanium, you need modify the function clone(). On IA-64, a different system call is used: int __clone2(int (*fn)(void *), void *child_stack_base, size_t stack_size, int flags, void *arg, ... /* pid_t *pid, struct user_desc *tls, pid_t *ctid */ ); The __clone2() system call operates in the same way as clone(), except that child_stack_base points to the lowest address of the child's stack area, and stack_size specifies the size of the stack pointed to by child_stack_base. The function clone() is used in /src/lxc_container.c. -Dustin. _________________________________________________________________ Windows Live: Friends get your Flickr, Yelp, and Digg updates when they e-mail you. http://www.microsoft.com/middleeast/windows/windowslive/see-it-in-action/soc...

Thanks for the info. FYI, you can work around it with --without-lxc to disable build of the LXC driver 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 :|

Hmmm, I'm not sure that those flags make sense on ia64 do they ? Perhaps someone more knowledgable can confirm, but I thought they were x86 concepts
