I am doing basically what you are asking. Here is my hardware breakdown: 1 x NZXT H440 Case 1 x MSI - Z87-G45 GAMING (MS-7821) 1 x Intel® Core™ i7-4790K CPU @ 4.00GHz 1 x NZXT Kraken X60 Water Cooler for CPU 1 x ASUS GeForce GTX 970 Turbo 4 x 4GB DDR 3 RAM (16GB total) 1 x Qualquam Killer Networking NIC (Built in to Mobo) 1 x Intel Corporation 82574L 1 x SiI 3124 PCI-X Serial ATA Controller 1 x ASM1062 Serial ATA Controller 1 x Fresco Logic FL1100 USB 3.0 Host Controller 2 x Samsung 850 EVO 500GB (Cache drive pool, effective 500GB) 1 x HGST Deskstar NAS 3.5" 4TB 7200RPM (Cache Drive) 1 x Seagate NAS HDD ST4000VN000 4TB 7 x WD Red 4TB NAS Hard Disk Drive My unRAID effective capacity is 32TB and my 500GB cache drive is solely used for Docker and my VM's This setup works amazingly and there is no game doesn't play at max graphics settings at 1080p at 60+ FPS. This setup cost a lot though, probably close to $3500 if not more but it has been one hell of a fun project and hobby. Setting up the Win 10 VM took a good month and I just spent another 5 hours on it today tweaking it for unRAID 6.2 which I just upgraded to. The only problems I have right now, is sometimes the VM will crash after running for 10 plus days without rebooting unRAID (now this was on unRAID 6.1.9 and I hoping 6.2 has resolved this) and audio crackling every so often, which doesn't bother me really but is there. Any questions you have shoot em over, happy to help. You would want to connect this rig to your TV directly with an HDMI cable for gaming. EDIT - Added Video Card

You need to set the VM settings to default to br0 interface, and then change your VM to br0 interface. There is no more xenbr0. I solved the issue by the method above, but guess that this caused some sort of issue because network issues are occurring. DNS for local computers on my network is not working. Prior to the upgrade I could rung "ping htpc" and it would work just fine, post upgrade I get the error that the host cannot be resolved. I cannot access any shares from the Windows VM. When trying to access them an authentication box pops up asking for a username and password. Shares do work from other PC's on the network so this definitely a VM specific issue I think.

Upgrade to 6.2 Attempt number 2. So I encountered the same issues so far in attempt number 2 (NIC getting reassigned, Docker going hair wire, VM's not starting). I have reconfigured the network so that is fixed. I have rebuilt all of docker however still have an issue with my Docker Versions not acting right. Some of my dockers say "update ready", one says "up to date" and all the rest say "not available". I have clicked "update" on all of them and the issue remains. The one that says "update ready" finishes with "The command finished successfully!" however the message never goes away. The ones that say "not available" are not changing status no matter what I do. Any advice on the docker issue? My Win 10 VM is also still pooched. It won't start, giving the error code "Cannot get interface MTU on 'xenbr0': No such device" I solved this by creating a new VM, going in to edit the XML and then copying the value in <source bridge='virbr0'/> from the new one to the old one. This now allows my VM to start. Testing continues....

This is a great point. I didn't even read the OP because there was an update button. I just clicked update and "assumed", quite wrongly it seems, that unRAID would walk me through the update process.

Here is my experience with 6.2. Suffice to say it was a failure. I logged in to unRAID today to see that there was an upgrade listed in the Plugins menu. I am running 6.1.9 so figured why not give a try. Here are the steps I followed. 1. Updated all other Plugin first. (Powerdown Package, FCP, Dynamix System Plugins) 2. Stopped all Dockers 3. Backed up entire Flash contents. 4. Updated unRAID via the button in Plugins 5. Rebooted server per instructions on Plugins page 6. The boot up took about 9 mins but finally booted to normal terminal prompt (non gui) 7. Shares did not work, couldn't access unMenu, could log in though so did that but couldn't do anything else. Ran ifconfig and it reported my ethernet was missing. 8. Rebooted in to new Gui boot up method. Took about 3 min to get to Gui but a full 10 min to finally show the unRAID interface page. 9. I have two NIC's so went to settings and found that 6.2 switched my NIC assignents so eth0 (the adapter that was configured for unRAID) was the unused NIC 10. Swapped the assignments so the proper NICs were in use. 11. Rebooted per the instructions back in to GUI mode 12. Booted up to firefox in about 5 min however too another 10 minutes for the bootGUI webmenu to finally load Once booted up things began to quickly fall apart. The GUI screen was not working right. It was taking forever to load and switch tabs. Images would not load for the Dashboard tab. The shares were not accessible. My Dockers apps were not reachable. All Docker apps showed an unknown version in red. My main VM wouldn't load, just threw up errors. I tried to fool around with stuff and search online for answers but I couldn't find anything so I deleted everything and restored the backup. I am now back running on 6.1.9 and enduring a parity check because of an unclean shutdown. If limetech would like to use me as a test bed for an updgrade to help out others then please let me know but right now it appears that a clean upgrade is not in the cards for a complex 6.1.9 setup

Hello All, I run two unRAID servers, a main one and a backup one. For the past year or so I have been using BTSync to keep the two in sync. Unfortunately though I have noticed that for 20 days in August all files that were sync'd between the two machines have become corrupted on both machines. This has cause loss of data which is exactly what I was trying to avoid by having two servers in the first place. Instead of figuring out why (though I think I know it but can't prove it) I am looking to switch to another way of keeping the servers in Sync. I have read on the forums that rsync is a good tool to use but have no knowledge in the tool. I am happy to learn it but was wondering if there was a tutorial for unRAID server syncing for it or some post with instructions. Any help would be appreciated as I know a lot of users have this setup already. Alternatively I have heard some users have had success with SyncBack but again have no knowledge in that tool either so any tutorial on that would also be great. I would love to see a native function built in to the unRAID but I bet that is asking too much at the moment. Does anyone have any other ideas or thoughts? Thanks!

This is now [RESOLVED] The issue was errant log files in Docker eating up all of the space in the image. There we no Containers downloading into themselves or anything like that. The img filled up and thus Dockers db couldn't load which prevented unRAID from register the Docker Tab. Running this command lists the sizes of the logs du -ah /var/lib/docker/containers/ | grep -v "/$" | sort -rh | head -60 I couldn't figure out how to delete the logs only so I deleted the Docker image file in Settings -> Docker page and recreated a new docker image after. Then after adding all the Containers back via the GUI using the [templates-user] section I was back in business. All Containers created back up just like they were before I blew away the img. Thanks Squid for all the assistance.

OK thanks Squid...appreciate your assistance

OK so I have found that I am out of space because of log files by reading these threads - http://lime-technology.com/forum/index.php?topic=45249.15 But I do not know how to clear the log files... I don't know how to do this as I have no GUI options

Not without diagnostics when I try to run the Daemon from command prompt I get this. root@Tower:~# docker -d INFO[0000] Listening for HTTP on unix (/var/run/docker.sock) INFO[0000] [graphdriver] using prior storage driver "btrfs" FATA[0000] Error starting daemon: Insertion failed because database is full: database or disk is full

Sorry, diags posted tower-diagnostics-20160602-2138.zip

Rhuh roh... I have rebooted the unRAID server and now my Dockers can't be reached and there is still no Docker tab. I have turned 'off' Docker and turned it back 'on' and the tab is still missing. I have increased the size but the tab is still missing. Thoughts?

OK I think I have found an issue. My sabnzbd folder is complaining about not enough disk space but I do not know why because I have all the "folders" setup correctly under Config and the sabnzbd Queue is showing 2.1TB of free space. Which is accurate. ERROR 31/05/2016 16:23 [31/May/2016:16:23:02] HTTP Traceback (most recent call last): File "/usr/share/sabnzbdplus/cherrypy/_cprequest.py", line 663, in respond self.body.process() File "/usr/share/sabnzbdplus/cherrypy/_cpreqbody.py", line 996, in process super(RequestBody, self).process() File "/usr/share/sabnzbdplus/cherrypy/_cpreqbody.py", line 540, in process proc(self) File "/usr/share/sabnzbdplus/cherrypy/_cpreqbody.py", line 223, in process_multipart_form_data process_multipart(entity) File "/usr/share/sabnzbdplus/cherrypy/_cpreqbody.py", line 215, in process_multipart part.process() File "/usr/share/sabnzbdplus/cherrypy/_cpreqbody.py", line 538, in process self.default_proc() File "/usr/share/sabnzbdplus/cherrypy/_cpreqbody.py", line 710, in default_proc self.file = self.read_into_file() File "/usr/share/sabnzbdplus/cherrypy/_cpreqbody.py", line 725, in read_into_file self.read_lines_to_boundary(fp_out=fp_out) File "/usr/share/sabnzbdplus/cherrypy/_cpreqbody.py", line 682, in read_lines_to_boundary fp_out.write(line) IOError: [Errno 28] No space left on device How can I tell the "size" of each container to narrow down which one is causing the bloat?

Quick Fix: Make your docker image larger (settings -> docker) and hope for the best Better Fix: Delete the docker image from settings-docker, recreate it at a larger size and re-add all of your previously used apps (CA's previous Apps section). After the downloads, it'll be like nothing changed Real Fix: Figure out why it filled up (are downloads, etc being saved into it?) Thanks for the suggestions. What is "CA's previous Apps section"? I would like to do the Real Fix. How do I figure out what is downloading in to docker image?

Hey All, A wierd issue just started happening. My Docker tab is missing from the nav. On the Dashboard tab none of my Dockers are showing. When I got to http://unraid/Docker the page just shows the header and the footer but everything else is blank. ALL Dockers are responding and working just fine though. Fix Common Problems addon spit out this message Docker critical image disk utilization: 31-05-2016 15:19 Alert [TOWER] - Docker image disk utilization of 100% Docker utilization of image file /mnt/cache/appdata/docker.img And thoughts on how to fix this?

OK thanks for the tip. I am certain there is a memory leak in unRAID because my crashes get worse and worse as uptime progresses. I eventually reboot unRAID and I am stable again for about 6 - 8 days. Limetech I am happy to work with you to figure out this problem. I am certain getting to the root cause will in fact uncover a real bug that can then be fixed.

Have had two more crashes. Attached is the diagnostics file. tower-diagnostics-20160528-1128.zip

Thanks for the insight. The next time it happens I will post both.

Anyone able to look at the syslog and see what is causing the OOM situation?

OK so I have had a crash today. Here is the syslog. Can we find out from this log what is eating up all my memory? syslog.txt

Since you say it is "likely" how do I determine 100% that this is the issue? Are there no logs or dump files or crash reports that I can check to validate this assumption? All the other VM providers you have used don't have Docker Containers or NAS functionality running as part of the host OS. If you want a pure VM-only hypervisor solution, we are not the choice. If you're looking for an "enterprise-grade" solution, we are not the choice. We provide consolidated functionality in a server OS where VMs are one of the features, but not the only or defining feature. You also can set a memory limit to the host OS (see here: http://stackoverflow.com/questions/13484016/setting-limit-to-total-physical-memory-available-in-linux). I thinks you are being too flipant black and white on your comment about what your software is and is not. I am not looking for the things you mention as not being, but what I am looking for is a product that works well and is stable with all the advertised features enabled. I am not doing anything fancy or custom, I have not enabled any third party add-ons or mods to achieve the results I have. I am simply using all of the OOTB functionality that is available so I would expect the system to work like that without my VM's crashing every 2 - 5 days. If I am truly oversubscribing the memory then there should be a way to a. prove that and b. tell me that during normal use so that I don't run in to such a frustrating road block.

Thanks I didn't realize the forums were not for support. I will contact them.

Well I thought I had this licked by adjusting the memory on dockers and what not but it happened again just on Friday. Limetech are you out there? Why don't you provide answers to questions like this?

Limetech can you please provide some guidance around the logging question?

Thanks Squid, I have put the parameter in place and monitor. My main question still remains, is there not a more verbose logging for KVM somewhere?
