Weird VM move problem - HyperV 2012

Hi,
We’re currently running an evaluation of HyperV 3.0 (we’re a VMWare house currently) and we have two HyperV hosts, one in each of our data centres.
We’ve created a single VM on each host and are currently in the process of testing the VM move process.
On each host we have two Virtual switches. One of the virtual switches is configured for the local VLAN at each datacentre. The other virtual switch is a common “extended” VLAN which exists on both hosts.
With only the two “local” switches in place, we can move the VM from host to host without a problem. However, with the common VLAN switch in place on both hosts, we consistently get the following error:
This appears to not be a networking issue. When both VMs are configured on the “extended” VLAN, we can successfully ping the VMs across the link – but the move simply refuses to work.
Does anyone have any ideas as to what to try next?
 Cheers Steve

Make sure you initiate the 'move' (e.g. Live Migration) from the Hyper-V Manager console running on the
source server. You can only use the Hyper-V Manager console on the destionation server only when you ahve configured Kerberos authentication for Live Migration.

  • HyperV 2012 R2 Failover cluster, HV problem, all VMs restart

    Hello, I have 2 node Failover cluster with two nodes, Hyperv 2012, multipath SAS storage MSA2000. But hardware problem with one node (node2). It shutdown unexpectly. When It hapens NODE1 restar all VMs it is normal? It was configured by cluster validation
    tool. There is no witness. I don't clearly understand what happens if one node crash. KR.

    As Eric has said it will start the VM's in a crash consistent state on the non crashed host.
    But from your example I take your seeing your guests on the non crashed host restart. If this is the case I would say yes! I have seen this happen before. It can happen if your not using quorum because only one node has a vote. I would recommend you create
    a witness, on your MSA 2000 carve out 1 GB and do a disk witness. Or if you have a server not in the VM cluster you could do a file share witness, file share is my preferred. Once you have a witness in play you will see all of your hosts having a vote. Look
    in the cluster manager at the nodes section. You should see a vote column. Currently it will say 1/0, once the witness is created it will show 1/1.

  • Why is it not possible to move a SCCM 2012 Server to a new Domain?

    Hello everybody,
    I know it is not supported to move a SCCM 2012 Server to a new Domain. But I am still missing why it is not supported or possible....
    I could not find anything that explained it in detail on the forums/internet. So when the question comes up in front of a customer it is always better to have a good argumentation...Can somebody describe the reasons why??
    Thank you very much in advance!

    Have them call CSS then.
    It's ultimately the result of the design of the product but not an explicit decision. To my knowledge, it relies on the domain name for certain things and this is explicitly embedded with no defined way to change this. Could it be changed? Probably.
    But, that would take a lot of work and effort and is not something Microsoft has ever invested any time in.
    The grass is green and the sky is blue. Knowing why doesn't change these.

  • VM windows 2008 Cluster on Hyperv 2012 Server FC Disk error after Live Migration of the active VM Cluster Node

    Deployed a 2 nodes Windows 2008 R2 SP1 Failover Cluster on a HyperV 2012 Server cluster deployed on IBM HS23 blade.
    Disk susbsystem is IBM Storwize V7000. MPIO driver installed plus IBM DDSM.
    Lun presented to the VM are connected with Virtual FC Adapter and everything works fine in the cluster until we start a live migration of the VM which hold the cluster disks online.
    After migration complete positively, at the moment the MPIO of the migrated VM goes crazy with a lot of errors (source: mpio eventID 16 ) and warnings (source: mpio EventID: 17) in the system event log. After that the disks becomes unavailable.
    Consequently everything hangs until power off the migrated vm, so the services on the cluster switchs on the second node.
    I try to set the registry key HKLM\CurrentControlSet\Services\Disk\TimeOutValue to 190 as i found on various articles but nothing seems to change....
    Any idea?

    Hello,
    I've just been through the IBM interoperability matrix and came across this statement:
    Hyper-V on x64 based systems is supported with the following guest OS: Windows 2003 32bit, Windows 2003 64bit, Windows 2008 32bit, Windows 2008 64bit.
    Clustering of guest OS is not supported at this time. When using Emulex HBAs with Hyper-V please select the settings mentioned in the Host Attachment section of SVC Info Center

    Thanks

  • HyperV 2012 R2 Multiple VM Copies

    I have 2 HyperV 2012 R2 servers in a datacenter and 1 HyperV 2012 R2 server in a disaster recovery site. Both servers at DC have access to shared storage (fibre based SAN) if needed. Ideally, I would like a given VM to reside on DCVM1 and auto-failover
    to DCVM2. However, I would also like the possibility of failover (manual is fine) to DRVM1 should the DC fail. What combo of technologies would I need (failover clustering, HyperV replication, etc) to make this happen. I tried replication, but it only let
    me replicate to 1 machine. Clustering seems to remove the replication option.

    You cannot combine replication and guest VM cluster if you're using disk as a quorum for your cluster (file share is OK at the same time). If you need both technologies and need to have disk quorum you'll have to install some third-party tool putting agenst
    inside a VMs and being aware of the fact VM is clustered.

  • HyperV 2012 network performance problem with Teaming 4x1Gbit.

    Hello everyone,
    2 VMs from the same host sending Iperf test to an external ressource (out of the External Vswitch), simultaneously, don't get more than 1 Gibt/s through the Team.
    I've tried every kind of configuration (switch dependent/independent, VMS/no VMQ, RSS, SMB...) but I haven't test it from scratch (fresh 2012 install, HyperV role, no script, no VMM...).
    Critical patches are applied, network card drivers (Intel) are up to date.
    The host is configured with Vnics, there is only one Vswitch attached to the physical team.
    The vlan are tagged on the Vnic of the VMs.
    The access switches are stack of 2960 Cisco's, with scr-dts-ip as load-balancing algorithm.
    Every TCP session should be multiplexed on the different physical adapters, am i right?
    Thanks in advance for your participation :)

    Stef,
    When you configure a team with let's say four 1GbE interfaces, the following applies:
    When you create a 'switch independent' team; outbound you will have 4x1Gb, but inbound you will only have 1x1Gb bandwidth.
    When you create a 'switch assisted' team with LACP enabled; outbound you will have 4x1Gb, and inbound you will have 4x1Gb bandwidth as well.
    You will NOT get 4Gb of bandwith with a single session. Instead you can get 4x1Gb bandwidth with multiple sessions (between different sources/destinations). A 'switch assisted' team with LACP is in fact a Port-Channel or sometimes known
    as an Ether-Channel, which is then bi-directional, the same as between physical switches. If you think about it, a Port-Channel on a switch does not offer you 4GB either, you get 4x1Gb bandwidth.
    VMQ does not apply to 1Gb interfaces. Even though you have enabled it, it is automatically disabled by Windows. Unless you add a special registrey key. VMQ is the equalivant for RSS but then for VMs and only offers CPU load distribution for network throughput.
    As mentioned, RSS is simulair to VMQ. But RSS is offered to the parent OS, and VMQ is offered to the guest OS. Keep in mind. RSS should ONLY be enabled on interfaces used by the parent OS and is automatically disabled when you configure a vSwitch on that
    interface. VMQ should ONLY be enabled on interfaces that host a vSwitch.
    So, the bandwidth you are getting is how it should work. I hope this information makes a bit more sense to you.

  • Weird event display problem in week view

    Hi. I'm getting a weird display problem in week view. First time this has ever happened.
    Some events appear to be missing, but when i double click on where I know the event is supposed to be, a new event is created (as excepted), and the missing events suddenly appear. When i move forward or back by a week, and then return to the week in question, the missing events are gone again. But, I can see the missing events in day view or month view.
    Any ideas?

    Dean,
    Next, try reinstalling the Mac OS X v10.6.2 Update (Combo).
    If that is unsuccessful:
    1. Use iCal>Export...>for each one of your individual calendars.
    2. Delete all but one of your calendars.
    3. Create a calendar and name it "Test."
    4. Delete the calendar which remained after step #2.
    5. Quit iCal.
    6. Remove the iCal plist, and drag the iCal plist file to your Desktop.
    7. Log out/in or restart.
    8. Restart iCal and use iCal>File>Import...for each one of the calendars that you exported in step #1.
    9. Delete the "Test" calendar, and any "Home/Work" calendar which was automatically created when you opened iCal in step #8.

  • Unwanted Cursor Move Problem

    Hello
    I have a problem about cursors in XY Graph. I have two cursors and I want to get data between two cursors. I have snapped the cursors to the plot however, cursors perform unwanted move when I make them visible. hope there will be someone to help me.

    You did not include any of your subVIs, but overall the code looks weird. Wy do you use a 1ms timeout to rattle through numerous property nodes of the same graph. That's a very nervous program. At least combine all thse property nodes into one and use a more reasonable timeout.
    Can you attach a runnable version that includes all subVIs? Thanks!
    We also cannot see the cursors because they are locked to a plot, but the plot has no data.

  • Weird Flash Video Problem

    Hello,
    I've just got my first MacBook Pro and I have a weird problem with Flash Player. I have Snow Leopard 10.6.4, everything up to date, and I have a problem when watching movies. The problem is current in both Chrome and Safari, but only with 10.1. I have tried several 10.1 versions and they all do the same thing: from 2 to 2 minutes, the video pauses for 2-3 seconds while audio keeps on playing normally. Version 10.1.103.19 in Chrome does the same thing, 10.1.102.64 same, but 10.0.45 is working perfectly.
    I appreciate any help on the matter as nobody seems to know what the problem might be, and nothing seems to fix this.
    Thanks.

    Try to disable Hardware Acceleration (Flash Player Settings).
    If that does not help, as I know nothing about Mac OS, all I can do is point you to the troubleshooting page http://kb2.adobe.com/cps/865/cpsid_86551.html

  • Weird contrast adjustment problem...

    I've been attempting to emulate the in-camera settings I use on my Olympus E510 in order to preserve highlights, but are those that are only used by the Olympus Viewer software. In doing so I have found what might be a bug, although I'm not sure what with.
    I've left Raw Fine Tuning to the Apple default settings, and using the 'Highlight/Shadow' view. If I see clipping in both shadows and highlights, I've been trying out a method of turning down the contrast a little (using the Enhance brick). One click on the arrow sets it to -0.05, which is just enough usually.
    However, I have found that it often recovers more of the shadow than the highlights. If I then try to bring up the Blackpoint adjuster, the shadows darken, but the blue indicator does not operate at all, it seems like the scale in the histogram has hit a kind of wall, and doesn't actually move down to the clipped zone.
    At the other end of the scale, the highlights display as expected, and the red clipping indicator shows up as you make adjustments.
    Anyone else seeing this?
    Thanks
    Andy.

    I just figured something out. If I disable the three finger drag for the trackpad the problem goes away.  That's a weird bug.  Any workaround?

  • What the Heck???  Quicktime Movie Problem....

    Hi. I really hope someone can help.
    I basically want to create a Quicktime Movie; however, when completed, the item properties are not always the same as the custom Quicktime Movie settings I chose.
    Here are my sequence settings in FCP:
    HD (960x720) (16:9)
    Pixel Aspect Ratio: HD (960x720)
    Anamorphic box unchecked
    Editing Timebase: 23.98
    Quicktime Video Settings: DVCPRO HD 720p60.
    That's the timeline I work on - no problems.
    Then I try to export using Quicktime Movie with these Custom settings:
    Frame Size: 960x720 - HD (960x720) (16:9)
    Pixel Aspect Ratio: HD (960x720)
    Anamorphic box unchecked
    Editing Timebase: 23.98
    Timecode Rate: Same As Editing Timebase
    Quicktime Video Settings: DVCPRO HD 720p60.
    *SOMETIMES IT WORKS, SOMETIMES IT DOESN'T!*
    When it does work, nothing changes; the Item Properties are the same as the settings I chose upon export and the Quicktime Movie does not need to be rendered when imported back to the original sequence.
    However, at times the settings change as such:
    Frame Size: 1280x720
    Pixel Aspect: Square.
    NOTE: I have never been able to successfully export the entire sequence (TRT:00:02:56). When it did work and the settings remained the same, I only attempted to export a small portion of the sequence.
    The sequence is comprised of only audio/video, a couple of slugs, and a couple of title cards.
    Thanks

    Thanks for the reply.
    Current settings did not make a difference since I essentially was using current settings by manually plugging them in under "Custom."
    Unfortunately, I had to plug-and-chug my way through. After two hours and over 30 QuickTime movies, I found three trouble spots:
    1) A slug at the beginning;
    2) A cross dissolve between two clips;
    3) A cut within one clip.
    VERY ODD!!! Once I removed these conditions, e.g., eliminated the slug and started hard on the clip, removed the cross dissolve, and eliminating the cut, I was able to successfully create a QuickTime movie of the entire sequence at the current settings.
    Why? So weird!!! The thing that confuses me the most is that the three conditions were so different (seemingly, at least). I couldn't find any common situation.
    Any thoughts anyone???

  • Rent-Movie-Problem -1309

    Hey Communitie,
    I've got a third time problems with Rent-Movies on iTunes.
    I have the white MacBook from 2009 and all my stuff is updated!
    I rent three movies on iTunes:
    - "Tron: Legacy" in September 2011
    - "John Carter" in May 2012
    - "Hunger Games" in August 2012
    All movies stops exactly on 4GB with the default-message "-1309", that I don't have internet-connection, but this is not true, all other downloads (series, apps etc.) still working at the same time. So the Apple-Support must still delete the downloads from these rent-movies... nothing other I can do!
    All other rent-movies I've done still works.
    The same movies I've rent on my iPad and there still working too... So I don't understand, where is the problem on my MacBook.
    Can anyone help me?
    Ich bin natürlich auch in Deutsch zu erreichen.
    Grüße

  • Weird Audio bleed problem on PCs only beginning at new year.

    Here is my test page showing the issue:
    http://jeanmarzollo.com/march10/TEST/
    At the new year, suddenly my animated children's books (built with one book page per scene mostly, all of which wait for the child to click the "next" button to turn the page) suddenly on windows PCs, each page would stop visually as usual, but continue to play the following page's audio (just one next page).  The audio definitely is not hidden on that scene, it's the NEXT scene's audio.  Can't understand why that would happen.
    I did a work-around fix by adding a "stop all sounds" action in addition to the "stop" at the end of each scene, but it can cause weird little issues. On this test page I made you'll see the earlier versions of the ebooks at the top of the page which worked fine before the new year and now show the issue that began at the new year (only on a windows machine). You have to go to past the cover page to see the problem (you can use the little lightning bolt arrow to avoid waiting through the whole intro).  My fixed versions are below.
    I just thought it was an odd little glitch that people might want to be aware of... I AM using Action Script 2.0... These are very simple little animations to match the child-like illustration style.... I do like Jean's painty illustrations to animate with.  Even though it can't resize, I think it's worth it.  (Jean Marzollo is the author/illustrator, and if you have little kids, they'll love all the free stuff on her site http://www.jeanmarzollo.com)
    Does anyone know why this could have happened?  Is it a windows operating system change (it happens to the movies whether they are served through IE or Firefox)?  Is anybody else experiencing any weird things with previously working movies that suddenly developed glitches after the new year?
    Thanks!

  • Some playlists don't show up - weird iPod syncing problems

    Apologies if this question has been answered elsewhere - couldn't find the answer when I was searching the boards last night. Don't know if this is an iTunes problem or an issue with the touch...
    Last night, I plugged my iPod touch (1G) into my MacPro to add some new music. This is when things got weird!
    First, I noticed that my iPod's name had mysteriously changed since the last time I synced it. It used to be called "Christine's iPod" and now it has reverted to the default "iPod touch."
    Next, when I went to add some different playlists to the iPod, I noticed that one of the playlists I wanted to add didn't show up in the Music tab, so I couldn't "tick" it for inclusion on the iPod. This isn't a new playlist, and I have successfully synced it with this iPod in the past. I tried renaming the playlist and making a new playlist with the same songs, and neither of these playlists showed up either. BTW, I definitely don't have too many playlists - I probably have 100-150 playlists total.
    Anyway, I restored my iPod and starting from scratch - and the playlist still didn't appear to be available to sync. I ended up adding the playlist by "manually managing" my music, but this isn't an ideal solution. I'd like to be able to sync the playlist!!
    Don't know if it's relevant, but my bf also has an iPod touch that he syncs to the same iTunes account. We have separate computer logins, and our iTunes Library is on a shared disk on our MacPro (to prevent needlessly wasting HD space due to song replication) and occasionally we both get messages saying we don't own or don't have permission to access the Library when opening iTunes. To solve this, we alter the permissions on the disk and apply to enclosed items. Maybe this happens after updating iTunes or adding new songs? Not certain what triggers it.
    Thanks in advance - this is really bugging me!

    This isn't foolproof but there are usually two things that contribute to songs not appearing under Artist on the iPod, both due to information either in or missing from the Get Info>Info tab against the song in iTunes. 1) the song has no album name associated with it or 2) the song is marked as part of a compilation.
    If tracks are missing an Album name (as mentioned above) in the Info tab, this information needs to be filled in. The no album one is a bit quirky as the songs will appear under certain circumstances but the simplest remedy is just add None or Miscellaneous in place of a title. See this link for more detail: I don't see some of my songs when browsing by artist on my iPod
    Also if the tracks are ticked in the Get Info>Info tab as part of a compilation, they will not appear under Artist on the iPod. Highlight a song in iTunes that you know is not appearing correctly on your iPod. Right click on it and choose Get Info and click the Info tab (alternatively choose Get Info from the File menu), if "Part of a Compilation" is marked untick it and afterwards update your iPod, you should find it now appears as normal. Compilations are stored in a separate folder in iTunes so the songs don't appear inside the normal Artist>Album folder which may be why this happens.
