Hello I'm trying to convert a HVM to PV dom0. The domU is a 10SP2 SLED ( Kernel 2.6.16.60-0.21 i386) and is a SLES11SP2 dom0 (Kernel 3.0.13-0.27-xen 64bit). The truth is that every tutorial I see it differently and I do not know where this error. When I start the domU, pvgrub shows the options but when I select the kenel-xen, returns the error "Boot loader did not return any data!" The truth is that no more look, I'm lost in the different ways of doing HVM to PV. Below the log shipping configuration files /--- domu.conf: name = "ajrPrueba_pv" maxmem = 300 memory = 300 bootloader="/usr/bin/pygrub" on_poweroff = "destroy" on_reboot = "restart" on_crash = "destroy" disk = [ "tap:qcow2:/mnt/xendomain/ajrPrueba_pv/SLED10_SP2_i586_disco3,xvda,w!" ,"tap:qcow2:/mnt/xendomain/ajrPrueba_pv/SLED10_SP2_i586_disco1,xvdb,w" ] \--- domu.conf: /--xend.log file when I start the domU [2012-10-18 12:25:52 3511] DEBUG (XendDomainInfo:103) XendDomainInfo.create(['vm', ['name', 'ajrPrueba_pv'], ['memory', 300], ['maxmem', 300], ['on_poweroff', 'destroy'], ['on_reboot', 'restart'], ['on_crash', 'destroy'], ['on_xend_start', 'ignore'], ['on_xend_stop', 'ignore'], ['vcpus', 2], ['oos', 1], ['bootloader', '/usr/bin/pygrub'], ['bootloader_args', ''], ['image', ['linux', ['videoram', 4], ['tsc_mode', 0], ['nomigrate', 0]]], ['s3_integrity', 1], ['device', ['tap', ['uname', 'tap:qcow2:/mnt/xendomain/ajrPrueba_pv/SLED10_SP2_i586_disco3'], ['dev', 'xvda'], ['mode', 'w!']]], ['device', ['tap', ['uname', 'tap:qcow2:/mnt/xendomain/ajrPrueba_pv/SLED10_SP2_i586_disco1'], ['dev', 'xvdb'], ['mode', 'w']]]]) [2012-10-18 12:25:52 3511] DEBUG (XendDomainInfo:2562) XendDomainInfo.constructDomain [2012-10-18 12:25:52 3511] DEBUG (balloon:206) Balloon: 308284 KiB free; need 16384; done.
