And machine pc differs in the definition between 6.3 and 6.4. virsh 6.3: <guest> <os_type>hvm</os_type> <arch name='x86_64'> <wordsize>64</wordsize> <emulator>/usr/libexec/qemu-kvm</emulator> <machine>rhel6.3.0</machine> <machine canonical='rhel6.3.0'>pc</machine> <machine>rhel6.2.0</machine> <machine>rhel6.1.0</machine> <machine>rhel6.0.0</machine> <machine>rhel5.5.0</machine> <machine>rhel5.4.4</machine> <machine>rhel5.4.0</machine> <domain type='qemu'> </domain> <domain type='kvm'> <emulator>/usr/libexec/qemu-kvm</emulator> </domain> </arch> <features> <cpuselection/> <deviceboot/> <acpi default='on' toggle='yes'/> <apic default='on' toggle='no'/> </features> </guest> virsh 6.4: <guest> <os_type>hvm</os_type> <arch name='x86_64'> <wordsize>64</wordsize> <emulator>/usr/libexec/qemu-kvm</emulator> <machine>rhel6.4.0</machine> <machine canonical='rhel6.4.0'>pc</machine> <machine>rhel6.3.0</machine> <machine>rhel6.2.0</machine> <machine>rhel6.1.0</machine> <machine>rhel6.0.0</machine> <machine>rhel5.5.0</machine> <machine>rhel5.4.4</machine> <machine>rhel5.4.0</machine> <domain type='qemu'> </domain> <domain type='kvm'> <emulator>/usr/libexec/qemu-kvm</emulator> </domain> </arch> <features> <cpuselection/> <deviceboot/> <acpi default='on' toggle='yes'/> <apic default='on' toggle='no'/> </features> </guest> Regards Patrick -- Lobster LOGsuite GmbH, Münchner Straße 15a, D-82319 Starnberg HRB 178831, Amtsgericht München Geschäftsführer: Dr. Martin Fischer, Rolf Henrich _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
