I've worked on a similar solution some years ago on an early build of 8.10 using KVM virtualization.  I was really interested in a single system supporting multiple TV's back then.  I had a motherboard with 3 PCI-x slots and put 3 cards in it and done VGA passthrough to 3 VM's.  Each of these I PXE booted MD's on.  I had some trouble getting the graphics to work, but I was able to get UI1 working pretty easily and had some success with UI2 masking before I got to busy and let this project lay dormant.

IMHO this would be my strongest opinion of how to build such a very unsupported configuration.  I was working with existing hardware I had.  I believe with enough experimentation to get the right motherboard one could get as many as 6 different VM MD's running this way.  You'd still need quite a bit of umff to handle this.  I was running on an single processor system.  My plan was, in the event this worked well, was to put this on a motherboard with dual Xeon's or dual i7's now, with 6 or so PCI-x slots.

I'd really like to be able to do passthrough of each HDMI/DVI output independent of the card.  This would let me have 2 or 3 MD's per card.  In this case one might have between 12 and 18 MD's on a single system.  And with LMCE core running on the metal, and installing the KVM kernel and parts one might build out a fairly large deployment on a single system.

In my use case, the LMCE core remained on an independent server, with only my test VM MD's on this virtualized box.

I would love love love to see LMCE embrace KVM or Xen.  Run each of the pieces of the core, Asterisk, DCE, etc in independent VM's.  This could do such things as allow each MD box to be a member of a cluster, and the core services could migrate between the least busy MD boxes.  I had this dream of trying to build out LMCE with MD's on my OpenStack cluster, but have never had time to really test this type of deployment.

All that to say, I work for a cloud service provider, working with virtualization everyday, it would be a huge, huge undertaking to re-architect LMCE to work this way fundamentally.  It would also require systems that had the VM bits in hardware, VTd VTx, etc, would require much different hardware than the light weight stuff we are all striving for, etc.

If someone really wants to support multiple MD's off of a single box however, this might be the most approachable solution.  Considering that the core runs pretty well as a VM now.

Hey Thom.  Could you make the Generic_PC binary available for download again?

After checking out your recent YouTube post with "send to" functionality within Nautilus scripts, I've got a new inspiration to play with PC integration.

I'm not sure my solution/configuration is the most elegant.  But for a year I have been doing as follows to fit with my network scheme and household members.

My first created user is Administrator, then Guest, then my personal account and other household accounts follow.  I use the same uid scheme on my workstations so NFS derived permissions are consistent, as I use the NFS exports across my network's Linux workstations.  Then I configure my orbiters to select certain users by default.  My common areas, Living Room TV, Dining Room PC, etc, are set to select user Guest by default.  And bedroom orbiters preselected to that user.  Configure your orbiters permissions settings and your there.  The Administrator account, once the other users are configured, I hide from the orbiters, and is only configured for consistency within my network, and to provide the Administrator samba share.

Not important to LinuxMCE, but I follow this same scheme, with uid's startiing at 10000 for my workstations, including Guest at 10001.  This method/configuration I use, has been the same for a year or so, works well, gives me "anonymity" at common orbiters by default, and fits with other common network user schemes.  This also fits with Windows Server 2003 providing Active Directory.  And would fit with this feature request scheme:

The only thing I could see that you may want to integrate into the default install of LinuxMCE is maybe to configure uid 10000 as Administrator, uid 10001 as Guest, and then ask the user for their household member accounts to follow.  But a individual network plan for your network would suffice.

As I read this threads comments a few more times, I get some further ideas on this subject.  That may alter my user scheme.  I could see use for a "household wide" or global user, that each orbiter is preselected too.  That user could have security mode access.  And a user would not have to be selected to change security mode.  This last thought I have not deployed, as my described configuration has worked for me.  This is interesting to consider options for.  If advanced features, like Samba domain server is to be implemented, a consistant user scheme, with Administrator and Guest accounts will be important.

Installation issues / Re: Asus motherboard "M3N78-EMH HDMI"

I have confirmed the same problems regardless of build.  Originally I was testing this under amd64 build.  But have now tried with core and MD image as i386 and using the prebuild, link provided .ko file.  To the same error result.  It runs just fine as a Hybrid, but fails to be usable strictly as an MD.

One question.  Could someone clerify this instruction please?

for S and G's ran depmod -a again

...maybe I misunderstand this command.

Alright, I've followed the instructions on Realtek 8168 drivers on the Wiki.  I've tried initially with an amd64 image, and then later changing to i386.  I've walked my way through the steps a few times.  However I still cannot successfully PXE boot.  I'm getting this error:

config: eth0: SIOCGIFINDEX: No such device
config: no devices to configure
init:  can't open /tmp/net-eth0.conf
[blah-blah] Kernel panic - not syncing: Attempted to kill init!

It still does not seem to initialize the network driver.  Any ideas?

I would strongly recommend you purchase an NVidia 7 series card, if you intend to run this as a Hybrid.  I purchased an NVidia 7300 PCIe card on Newegg for around 30$.  The 7 series cards work well, and will likely get you up and running to the point you could update the NVidia binary, and likely get the 8 series integrated card to work.  I wish you the best of luck with the 9 series card, there's been alot of reported problems with the 9 series and Linux distros in general.  I do have an 8600GT in another MD and it works flawlessly with the 7.10 included NVidia binary.  I chose the 8600 card because of success stories posted on the net, it appears the 8600 is the one 8 series chipset supported well with the 7.10 included drivers.

I've experienced many of the video display problems during install, and the post install black screen while using the onboard video card with both amd64 and i386 versions of LMCE.  But with the 7300 and the Intel NIC, the 7.10 amd64 DVD install performs predictably.  I've had this board working as a Hybrid, with the 7300 card, and an Intel Pro1000 NIC, using the 7.10 amd64 DVD install, stably for 4 days.  I plan to reconfigure my network so that this box is PXE booted as MD off my original core as intended, later this week.  And from all research and posts, it appears this board will make a better MD than Core, as it will eliminate the need to use the SATA or IDE ports.  Although I have had no problems, installing to a WD SATA 2, 500gb drive, from an IDE DVDR drive.  I hope that it perform better as an MD only though.  Currently with a Phenom Quad core chip in it, and 4 GB's of 800Mhz RAM, HD playback is subpar.  Currently my 4800+ dual core with only 2GB's of RAM performs much more admirably.

I haven't had time to again reconfigure, but will post as I reconfigure things toward the end of the week/weekend.

I have this board and am using it successfully as Hybrid.

Install media:
DVD install, 7.10 RC 2, amd64

AMD Phenom 9850 BLACK EDITION 2.5GHz Socket AM2+ 125W Quad-Core Processor
4 GB DDR2 800Mhz RAM

I have also added:
NVidia 7200 PCIe Graphics Card
Intel 1000 PT PCI-X 1x NIC

I originally purchased this board for duty as Living Room MD.  But had the reported NIC problem.  It would initially PXE boot, but would fail with NIC problems.  I purchased the Intel card, but have been unable to cause it to PXE boot.  If anyone has any experience with Intel's Boot Agent, what's the trick to enabling PXE boot?  I can not get it to show in the BIOS as an available boot option, nor do I get the PXE message during boot.  I have tried the Intel Boot Agent software, and using the dos command with switches to enable PXE boot, to no avail.

However, I have made this board work well as Hybrid, with Intel NIC, in single NIC configuration.  I have a Linux based firewall with DHCP server disabled.  I have modified my dhcpd.conf, dhcpd.conf.tpl, and interface files to support my firewall as gateway.  With my Linux firewall handling internet routing, and my LinuxMCE box doing DHCP.  My clients route correctly to the internet, and my MD's and other workstations pull DHCP addresses and PXE boot correctly.  I do prefer this, although it's outside the recommended setup.  In my experience, LinuxMCE does a poor job on routing.  My P2P clients, and many other download clients download at significantly lower speeds than with my firewall.

My system appears stable, although it's only been up for a day.  Running UI2 + Masking.

I will post again as I work to resolve my couple issues...

1)  NIC drivers...  then I can PXE boot this box, and use it as just an MD as planned.
2)  NVidia 8200 drivers for onboard video...  from other posts, just an upgrade of the NVidia drivers should resolve this.

I am using an 8600GT with 512mb ram and an 8500 with 256mb ram, and can see no difference in the performance.  I am ordering a MB right away for a new MD that has a 8200 on it, and would be interested to hear of others opinions on the merits of these model differences.  On that note, many use 6000 & 7000 series cards in HD 1080p modes with success, so I doubt the difference would be noticeable.

On the issue of network performance.  I would have to strongly recommend a wired connection, due to simplicity of PXE boot from bios of MD clients, bandwidth, and wireless flakiness sometimes.  I recommend gigabit (although not necessary, I have 10/100 and it works fine) due to it's now cheaper prices and availability of most MB/systems with gigabit onboard.  Wireless for an orbiter is fine.  And I've heard that up to 7 streams of media can be accommodated on a dedicated 100mb pipe.  So 54mb's (or more like 45mb's realistically) of 802.11g would likely be fine, if it were pretty reliable.  But the complexity of configuring PXE boot of a wifi card could be prohibitive.

Users / Re: Westinghouse LCD TV Service Port... USB? a cable for it?
« on: April 14, 2008, 03:19:03 am »
Yea, I believe that would be the right cable for you.  But like he said, it's a toss-up weather it would work for control or not.

Firstly, on LinuxMCE and customization...  I find it more customizable than most here imply.  Simply editing/creating/sorting scenarios, and regen'ing the orbiters let me remove buttons, like the TV button.  It can't remove columns of buttons, like lighting or climate, afaik.  And IT'S OPEN SOURCE MAN, it doesn't get more customizable than that...  :)  However, learning your way around the source tree for this project is daunting.  I hope more development/porting to Ubuntu projects will further document and remove abstractions from the current code base.  So I realize all can't learn or have time to anyhow, the source to edit it, let alone hone their programing skills to the point of being productive.  But it's there, coming, or could be had.

Second, on MythTV.  I find MythTV a beautiful application, and I would prolly not ever change my MythTV deployment to LinuxMCE as I am now, if it weren't for the advanced feature set.  I want automation, I want follow me, etc.  If I didn't need them, I'd still be using Mythbuntu.  And for Myth, one can remove the TV button from the main menu.  Must edit an xml file, that's not that difficult.  I know to some, using Myth when one doesn't want TV tuning might be overkill.  But many of the plugins to Myth are nice.  And a properly configured Myth deployment for just movies and music is still real nice.

Additionally there are several video only applications that may fit your bill.
Oxine - Xine full screen interface, simple, stable...
Rage - Rasterman, of Enlightenment 17 fame has written.  Simple in every way, but beautifully animated, that's what the E 17 library's do well.

Now, let me try to exempt myself from any flame happy posters.  I'm just a user of it all.  A long time user of MythTV and a current user of LinuxMCE.  LinuxMCE can be coaxed into working, it takes some tweaking sure, but I remember what it took to get MythTV alone installed and working pre KnoppMyth.  Thank you KnoppMyth!  Thank you Mythbuntu!  Thank you LinuxMCE!  ...all developers, integrators, and testers, that make this possible (without buying Creston), thanks.

Just wanted to chime in with the same issue.

However, the issue doesn't lead me to believe it chipset related.  I'm running a socket 775 P4, 2gb DDR2 533 ram, NVidia 8600, PVR150...  a very different configuration, with little in common with your AMD setups.  And have had this exact lockup using MythTV issue as well.  Maybe memory related.  Both with 7.10 beta 3 and beta 4.  MythTV runs fine for me as it does others of you, so long as it's without the -v all option.

I did see that it's been changed in the latest subversion.  And will be testing this on my configuration in the next couple days.  It has kept me from running lmce on my production TV, but I'll again replace MythBuntu with lmce and try it.

And thanks all for the solution!  :)
