I have a VM that I am able to run using qemu form a command prompt with no problems. I want to run it from within libvirt, so I converted my qemu command to XML using 'virsh domxml-from-native ...' My problem is that my libvirt does not seem to support the x86_64 architecture, so when I try to launch the VM, the kernel won't built since it was installed on x86_64. My os container is as follows (as imported by virsh):
<os> <type arch='i686' machine='pc-0.11'>hvm</type> <boot dev='hd'/> </os>
However, when I try to change it to this:
<os> <type arch='x86_64'>hvm</type> <boot dev='hd'/> </os>
I get the following message:
error: internal error os type 'hvm' & arch 'x86_64' combination is not supported
I've searched for a proper command line switch to build this option into libvirt, but I have not had any success. So how do I get libvirt to support the x86_64 arch?
Thanks, Steve

Ok, this confirms your host OS is x86_64, but it only shows a single guest entry for i386. This is because the 'qemu' binar is the 32-bit emulator. To make x86_64 guests work, you need to install the qemu-system-x86_64 binary, or a KVM binary called 'kvm' or 'qemu-kvm'. Once those are installed, you should see another <guest> appear in that capabilities XML 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 :|
