Updates to pluto_media.MediaType_AttributeType

• Added by pos on 2009-07-31:

INSERT INTO `MediaType_AttributeType` (`EK_MediaType`, `FK_AttributeType`, `Identifier`, `CombineAsOne`, `MediaSortOption`) VALUES
(7, 16, 0, 0, NULL),
(7, 29, 0, 0, NULL),
(7, 37, 0, 0, NULL),
(7, 47, 0, 0, NULL),
(7, 48, 0, 0, NULL);

move pluto_media.MediaType_AttributeType

ALTER TABLE `pluto_media`.MediaType_AttributeType RENAME `pluto_main`.`MediaType_AttributeType`;
ALTER TABLE `pluto_main`.`MediaType_AttributeType` CHANGE `EK_MediaType` `FK_MediaType` INT( 11 ) NOT NULL DEFAULT '0';
ALTER TABLE `pluto_main`.`MediaType_AttributeType` CHANGE `FK_AttributeType` `EK_AttributeType` INT( 11 ) NOT NULL DEFAULT '0';
ALTER TABLE `pluto_main`.`MediaType_AttributeType` DROP INDEX `FK_AttributeType` , ADD INDEX `EK_AttributeType` ( `EK_AttributeType` );
CREATE VIEW `pluto_media`.`MediaType_AttributeType` AS SELECT `FK_MediaType` AS 'EK_MediaType', `EK_AttributeType` AS 'FK_AttributeType', `Identifier`, `CombineAsOne`, `MediaSortOption` FROM `pluto_main`.`MediaType_AttributeType`;

LMCE 0810 virtualized on Ubuntu 9.04 and KVM

• inspired by http://forum.linuxmce.org/index.php?topic=8233.0
• installed Ubuntu 9.04 alternate amd64, basic text system
• downloaded kernel 2.6.30.4 from kernel.org, build according to https://wiki.ubuntu.com/KernelTeam/GitKernelBuild
• install kvm and stuff: https://help.ubuntu.com/community/KVM/Installation
• install kubuntu 8.10
  • download kubuntu 8.10 i386 desktop .iso
  • create an image file (qemu-img create -f qcow lmce0810.img 25G) or use an empty and unmounted partition (that's what I'm doing in the following)
  • create a file (lmce0810.xml) with the definition of your KVM domain:

<domain type='kvm'>
  <name>lmce0810</name>
  <memory>2097152</memory>
  <currentMemory>2097152</currentMemory>
  <vcpu>1</vcpu>
  <os>
    <type arch='x86_64' machine='pc'>hvm</type>
    <boot dev='cdrom'/>
  </os>
  <features>
    <acpi/>
  </features>
  <clock offset='utc'/>
  <on_poweroff>destroy</on_poweroff>
  <on_reboot>restart</on_reboot>
  <on_crash>destroy</on_crash>
  <devices>
    <emulator>/usr/bin/kvm</emulator>
    <disk type='block' device='disk'>
      <source dev='/dev/sda5'/>
      <target dev='hda' bus='ide'/>
    </disk>
    <disk type='file' device='cdrom'>
      <source file='/home/chris/kubuntu-8.10-desktop-i386.iso' />
      <target dev='hdc' bus='ide' />
      <readonly />
    </disk>
    <interface type='bridge'>
      <source bridge='brlmceext' />
    </interface>
    <input type='mouse' bus='ps2'/>
    <graphics type='vnc' port='5500' listen='192.168.177.24'/>
  </devices>
</domain>

• • on the shell: virsh --connect qemu:///system
  • in virsh: define lmce0810.xml, start lmce0810
  • connect via VNC and do the installation
• modify the definition of the KVM domain to not use the kubuntu installation CD and to have two ethernet connections:

<domain type='kvm'>
  <name>lmce0810</name>
  <memory>2097152</memory>
  <currentMemory>2097152</currentMemory>
  <vcpu>1</vcpu>
  <os>
    <type arch='x86_64' machine='pc'>hvm</type>
    <boot dev='hd'/>
  </os>
  <features>
    <acpi/>
  </features>
  <clock offset='utc'/>
  <on_poweroff>destroy</on_poweroff>
  <on_reboot>restart</on_reboot>
  <on_crash>destroy</on_crash>
  <devices>
    <emulator>/usr/bin/kvm</emulator>
    <disk type='block' device='disk'>
      <source dev='/dev/sda5'/>
      <target dev='hda' bus='ide'/>
    </disk>
    <interface type='bridge'>
      <source bridge='brlmceext' />
    </interface>
    <interface type='bridge'>
      <source bridge='brlmceint' />
    </interface>
    <input type='mouse' bus='ps2'/>
    <graphics type='vnc' port='5500' listen='192.168.177.24'/>
  </devices>
</domain>

• in virsh: undefine lmce0810, define lmce0810.xml, start lmce0810
• connect again via VNC and follow the LMCE0810-Alpha2 installation steps

Conclusion

After all this seemed to work. After finishing the LMCE installation, both AVWizard and the configuration wizard started and I was able to configure the system. One thing I noted was that not all videos from the wizard were played but this might also be a problem with my VNC setup. However, finally the system setup was done and the system came up showing orbiter (UI1).

Next steps will be to

• map physical devices into the domain (tuner cards, usb devices, serial ports)
• setup FreeNAS and connect it to LMCE's internal network in another KVM domain
• try to attach MDs and stuff to the internal network and see if that works

I will keep documenting my efforts here.
