February 18, 201412 yr But I would like to Tom adopt the power down adon into the build, why do we need to still using this? better to Tom add a proper Shutdown function on the UnRaid. //Peter Agreed.
February 18, 201412 yr That was mentioned before that there is no LVM support Thanks. I didn't saw that. I don't like to run things from my array, so LVM seems a easier way to go.
February 18, 201412 yr Its the same as a acpi command I *think*. In my experience my windows VM just totally ignores it. Machines you can 'console into' do work mostly. Sent from my Nexus 5 using Tapatalk xl shutdown -F would do the trick. Windows VMs needs GPLPV drivers installed and shutdown service enabled. Run "C:\Program Files\Xen PV Drivers\ShutdownMon.exe -i" to install shutdownmon as a service (in a command prompt if you want to get feedback that it succeeds). You need to run cmd as Administrator.

February 18, 201412 yr Yes. That should do the trick with sub volumes and snapper will be great. The .IMG files serve a purpose but btrfs is the future if lvm isn't available. Sent from my Nexus 5 using Tapatalk
February 18, 201412 yr What we are waiting for is instead are btrfs Hope w have it in B4 Is that just speculation, or did I miss some awesome news?
February 18, 201412 yr I cant remember where / when this was said but Tom has openly discussed btrfs support in future. I think with Xen support it makes perfect sense to include it sooner rather than later. Maybe Tom could jump in and clarify?

February 22, 201412 yr Hi guys I guess the whole idea of a beta, is that feedback is provided when anything strange is noted. I was extremely excited to see unraid merge with a VM type server, although i have to admit this is the first time i expose myself to XEN. trusting the unraid community though, i decided to jump into the testing pool with my only server ( thus it is my production and test baby ) i unsuccessfully tried beta3 twice this week, having weird issues both times. first time dom0 failed on me completely during a GPLPV install on a VM ( i lost connectivity to the DOM0/Unraid ip ( it would ping for 15 seconds, then drop for 5 minutes - just not enough to putty in an try and grab the syslog . System is headless, so i was stuck in that case) today i had the array almost completely fail on me (it was reporting read-only when trying to move files on my cache drive, lost connectivity to my windows7 VM, and upon stopping the array, it was reporting 10 of my 12 drives missing ( that alone there gave me a few more grey hairs ) upon falling back to V5 everything was restored - BEEEEG sigh or relief. (note to self - purchase a second key and a testing server next time ) system was up for 4 hours before it crashed. syslog is in link below : http://pastelink.me/dl/c408c5 I formattted my usb, and copied beta 3 onto it. also restored my config folder with the exception of config/plugins and the go file, thus keeping it as "stock" as possible Started the system, nothing strange was noted(eg all shares restored, and all drives was green). Enabled the Xen bridge as per instructions added a Windows 7 VM as per this instructions : - http://lime-technology.com/forum/index.php?topic=31674.msg288613#msg288613 The machine installed fine, and i enabled RDC towards it. didnt get the chance yet to install the GPLPV drivers ( i'm not sure if this could be a cause, but then also the GPLPV drivers caused a fatal DOM0 crash when i tried it earlier this week, so i decided i would try without it after this i just left the VM running ( was planning to install mysql and a few downloading tools later on, but a nap was more important roughly 3 hours later : could still ping the systems( host + VM) VM was not responding to RDC(RDC disconnected), and VNC was also non responsive trying to rename a file on my cache drive was also not succesfull, and was reporting readonly (typical with a reiserFS problem usually...) using "xl destroy windows7" i managed to force a shutdown on my VM ( seems like without GPLPV drivers it didn't want to listen to restart or shutdown....) i then went ahead to stop the array (was planning maintenance mode so that i can do a resisefs check) suprise suprise - a big list of missing drives. only drive that was showing was i think disk 1, and my cache drive... Not wanting to push my luck starting the array in such a state, i decided to abort. Managed to copy syslog to boot disk before initiating a shutdown i'm not sure what could have caused this issue, was hoping you guys could assist, so that a better bug report can be available for Tom / Limetech. system is semi old hardware (Quad core 2.4Ghz Q6600) with about 6GB of ram ( 2 for host 2 for VM). Drives is rather new though (mostly 3TB's western digital and cache a 2TB Seagate) System was and still is completely rock solid under V5 - parity checks is clean (monthly for about 4/5 months now), plugins stable ( Mysql/ Moviegrabber / Cachedirs / Fancontrol / unmenu) if any recommendations is possible as to what could cause this ( maybe a VM setting i missed?), i would try and assist to retest. ( or maybe a few more commands if the failure occurred?. I'm not exactly sure what went wrong - the syslog is Massive!! first sign of trouble was : Storage kernel: sd 11:0:4:0: [sdg] command ffff880024053c00 timed out , which usually is a controller/cable/drive problem I will monitor that drive ( SDG is my cache drive), for a bit in order to see if it is still an issue on V5, but i highly doubt it. if any other information is need, please ask thank you Neo_X *Edit* Reiser check was performed on the drive in question - no issues there.... I also noticed my VM settings file had HVM enabled. since this is possibly only supported for newer hardware, could this maybe be a cause? kernel = '/usr/lib/xen/boot/hvmloader' builder = 'hvm' ///and//// vif = [ 'type=ioemu, bridge=xenbr0' ] Ideas anyone? (i just dont want to leave this bone alone it seems ) windows.cfg
February 23, 201412 yr Ideas anyone? (i just dont want to leave this bone alone it seems ) I recommend running the memory check utility. When things just don't seem to follow logic, it's typically due to bad RAM.
February 23, 201412 yr I'm trying to run reiserfsck, but the kernel is killing it. I doubled my dom0 memory in syslinux.cfg, and reiserfsck completed successfully. append /xen dom0_mem=4194304 --- /bzimage --- /bzroot
February 24, 201412 yr Hi! I have the same problem as MrLondon, when i choose Xen/unRAID OS i get this screen (pic attached). But when going into "normal" unRAID OS. All is working just fine. But the solution to disable VT-d doesnt work. Ive also tried to disable VT-x and no execute memory settnings, but same with any settings. Any ideas? regards /jowe

February 24, 201412 yr Hi, sorry should have given more info! Motherboard: From a HP XW4600 workstation CPU Intel core2duo E8600 3,33 should have both VT-x and VT-d support Have tried different memory sticks, 4x2GB and 4x1GB /jowe
February 24, 201412 yr it should support it, it gets enabled this way How to enable Intel hardware virtualization on an HP xw4600: * Boot into the hardware BIOS setup * Got to Security -> System Security * Enable both types of virtualization (VTx and VTd) * Save settings, and power-cycle the machine.
February 24, 201412 yr Thanks, already tried both enable/disable the settings. Latest bios is applied. Maybe it´s just because its a HP mobo. They are probably made for very specific HW and SW usage... /jowe

They are probably made for very specific HW and SW usage... /jowe I'm using the same CPU as you in a Supermicro C2SEA motherboard and was unable to get it to work with ESX when I tried. Haven't tried this version of unRAID yet but wonder if it's something to do with this particular CPU. As it is one of the few Core2Duo ones that lists VT-d support.

February 24, 201412 yr I'm sorry to hear you're having troubles getting Xen to work. My quick Google search got me focused on this approach (http://www.shnake.com/?p=419: In the BIOS you need to change the following settings Security > Execute Disable (set to On) Performance > Virtualization (set to On) Performance > VT for Direct I/O Access (set to On) Performance > Trusted Execution (set to Off) Save and exit the BIOS, then power the computer down. You must power it down for the settings to take affect. Another "black magic" approach was to completely reset the BIOS, as in pull the battery for 5 minutes or so, and then re-enable VT. Also, consider using an earlier BIOS version. I hope it helps!
February 24, 201412 yr I dont have the exact same settings, but almost. Data Execution Prevention ENABLE Virtualization Technology (VTx) ENABLE Virtualization Technology Direct I/O (VTd) ENABLE Embedded Security Device Support DISABLE management of Embedded Security Device DISABLE I've tried the battery trick, and changing these settings on and off... But no change. Thanks for the suggestions! /jowe
