I am using Xen hypervisor. domPtr = lib.virDomainDefineXML(conPtr, domainXML); I get the following error: libvir: Xen Daemon error : XML error: failed to parse domain description This suggests there is an error in your xml. Would you mind sending the content of domainXML to this list? Jirka ___ libvirt-users mailing list libvirt-users@redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users
Re: [libvirt-users] Reg: Difference between chroot pivot_root
On Tue, Sep 06, 2011 at 01:02:14PM -0400, Alphonse Hansel Anthony wrote: Hi, What is the difference between chroot pivot_root. They don't seem obvious based on the man pages apart from the below mentioned caveats. 1) Inherited Open file descriptors, have to be explicitly closed. 2) Does not change CWD of the process, which can be overcome by doing a chdir before after chroot call. Any information on this would be useful. I assume you are asking wrt the libvirt LXC driver, which uses pivot_root instead of chroot() when setting up the guest. The primary reason for this is that chroot() is escapable, where as pivot_root() is not. https://s3hh.wordpress.com/2011/05/31/escaping-chroots/ Regards, Daniel -- |: http://berrange.com -o-http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :| ___ libvirt-users mailing list libvirt-users@redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users

It's just I am very surprised that an Intel Xeon E5430 is detected just as a pentium3 That's because your CPU doesn't support nx feature, which is included in all models better than pentium3.

In that case, I am going to check in the bios if it is just not enabled. Because, normally, this CPU should support it.
