• DRS and live Migration with the guest operating system issues

  Hello

  Someone at - he never encountered problems with the DRS or dynamic migration where the OS in question invited crashes under the peaks of the processor. This seems to be with servers but not specific to 64-bit or 32-bit servers it sure substance of concern with machinery that uses a lot of CPU or memory crash when migrating on the fly. We have 7 of Quad-Core AMD BL465 with esx3.5 update1 DRS and HA active and animators have many resources to offer.

• ESXi 4: error in live migration (VMotion) to the different data store (Local SATA to iSCSI SAN)

  Hi all

  I have a problem during VM migration live in the different data store, the specifications of the virtual machine is just Windows 2003 x 64 installed with the latest VMWare tools.

  Here is the error message:

  Move the virtual machine

  Win2003x64_RST01

  A general error occurred: detected Source this destination could not resume.

  The active state of VM migration

  any idea what could cause this please?

  Kind regards

  AWT

  Check that the machine ESX4 has prevention performance virtualization and data, indicators enabled in the BIOS. I could move 32 bit machines vmotion Unflagged VT turned on in the BIOS, but 64-bit machines could not begin until I activated the flag of VT in the BIOS.

  Also try to clear the mask of the source of the VM CPU before migrating, providing the hosts have the same hardware.

• How do you keep the guests on their hosts (no migration) by making the food stops.

  I apologize in advance for the length of this post.

  In general do not much poster, but a lot of reading.  First of all, let me tell you that I'm not a GURU PowerCLI, never written one in my life, but there is always a first time.

  Background:

  Under VMWare 4.1, that us did not run with HA, for whatever the reason why I don't know.  We had (our UPS manufacturer) Liebert software called MultiLink that when there was a power outage after 15 minutes would run a .bat file on the server vCenter for windows that would log on to the vmware host and run a file .sh that accumulate all the machines on the host and start making judgments on them.  Once completed the host itself would make a stop.

  Currently:

  Improved 5.5 VMWare vCenter, have HA and followed now host active in the configuration. We find that we can follow is no longer the practice that we have done less than 4.1.

  I got a new version 4.2.4 and that it contains, there is provision in interface with VMWare through the PowerCLI and it stops all guests on the host computer. The host then stops.

  I suspect STRONGLY that when the command is issued to stop the host itself, HA or monitoring kick and migrates customers and/or models out of the machine, before the machine shutsdown.  In the first tests, I had a host with 5 models, 1 windows machine and a Virtual Appliance on it.  Everything was arrested, as was that it was supposed to, but the host was brought back to the top he had nothing on it.  Models and machines had been moved (spread) for the two other machines.

  This has been confirmed in another test on 01/05/2015 through vCenter client connection, the guests have been stop, the by refreshing the screen you could see the machines leave the test machine, then the server itself, stop.  In a subsequent test, I commented on the "Shutdown the ESX hosts" part and the machine down and remained where they were.  So I'm guessing that it has something to do with HA, surveillance or other thing that needs to be defined differently for him to stop guests from the host, stop the host, BUT not to migrate comments to others running machines.  Do I need to enter the maintenance or standby mode before making the shutdown command?

  Any help would be greatly appreciated.

  You can avoid the confirmation prompt by adding the -confirm: $false pass.

  What follows will check all clusters and those where the priority of restarting is not disabled, is set to disabled.

  Get-Cluster |

  where {'ClusterRestartPriority', 'High', 'Medium', 'Low' - contains $_.} HARestartPriority} |

  HARestartPriority-set off Cluster - confirm: $false

  In this way, HA will continue to function (for ESXi other nodes in the cluster), but virtual machines will remain on the crux of ESXi, you stop.

• Is it possible for HA / VMotion to migrate a virtual computer when the fiber of SAN connectivity is lost / Cup?

  Use: Version ESX 4 / vCenter4

  I have a cluster with ESX 4 nodes running HA. I want to know if it is possible for vmotion to migrate a virtual computer if the host on which it lives has a loss of fiber optic connectivity to SAN/back-end storage. I can get VMotion to work when I go unplug the Ethernet cable to the back of the esx host, but when I unplug the fiber connections that will freeze the virtual machine and no migration will happen. Is it possible to do this with VMotion HA? I also tried to use aggressive DRS to see if when I unplug the fiber it lose connectivity and a loss of memory or cpu and migrate... so not happened... the vm always reports to vCenter that memory and cpu have not changed... then DRS don't not kick to migrate the virtual machine.

  Thank you.

  There is no such thing for HA. HA only fires when there is a host or a network isolation fails. DRS also does not realize this. However, there are a lot of events that can trigger an action such as "maintenance mode". don't know if there is a for the failures of way, just check it out. It is described in the following pdf document: http://www.vmware.com/pdf/vsphere4/r40_u1/vsp_40_u1_admin_guide.pdf

• Extremely high latency during the migration of the local data store to data store shared.

  Hi guys I hope you help me. Sorry for my English btw, I'm not native.

  Let's start!

  I have:

  1 vCenter
  1 host
  1 Distributed Switch (with a pg for managing network/IPstorage the esxi)
  1 standard switch (empty)
  1 FreeNAS to provide iSCSI LUNS
  1 Microsoft to provide iSCSI LUNS

  When I try to migrate virtual machines between the warehouses of shared data or data shared at local store, all right. The problem has become when I try to migrate virtual machines from the local to the shared data store. All data stores down (all paths down) and back up and I get this error:

  "Error caused by the /vmfs/volumes/volumenID/VMDirectory/Disk.vmdk file.

  
  When I try to migrate virtual machines from the local to the FreeNAS iSCSI data store it fails immediately.
  When I do the same local Microsoft iSCSI datastore that it takes a time loooooong to migrate the virtual computer, give it to me even all the paths downwards and uplinks down error but not lacking in migration.

  I'll give you some screenshots to see the errors.

  Thank you very much!

  EDIT: I have extremely high latency notice when I try to migrate from the premises of warehouses of shared data. average 2000ms with peaks of 50,000 (see my response below for more information)

  Finally, I found the solution! The problem is that I have been using E1000E vmnic instead of vmxnet3. I have configured an adapter vmxnet3 and boom! 20 ms in all migration!

  Thank you to all for help, especially Nick_Andreev !

• Is vMotion road data via the server vCenter Server?

  Hello

  I need help to solve a query I have.

  We currently have a vCenter server that manages certain clusters, but also some stand-alone hosts with local storage (not shared). Stand-alone hosts are physically located on remote sites. Some sites have more than one of these stand-alone hosts. We have an obligation to move a VM to a standalone host guest to another independent host on the same remote site.

  As there is no shared storage the VM should be stopped before trying the vMotion.

  The virtual machine in question has a 4 TB thick VMDK accrued that is migrated between the physical host computers.

  I think when the vMotion is launched the data will be limited to the subnet that the two physical hosts are connected and therefore use the bandwidth available via local network equipment and will not let the physical site. My colleague suggested, however, that data travels through the vCenter server. Of course, this would cause a problem to try to move the data so much and would effectively mean that this 4TB would leave travel via the vCenter server, remote site, then return to the remote site. Not only this would be very slow, it could also have a negative impact on bandwidth to and from the site.

  So my question is who is correct? (Assuming that one of us is!)

  Thank you

  When you start migrating cold from a virtual computer by selecting migrate both (host and storage) where your hosts are based in the same place, it will happen with esxi source and target host, it will not go all the way to your host to vCenter.

  If your environment is vSphere client of web use 5.1 or higher, and you can move VM while it is powered on and residing in the local storage of the host. This feature is called Cross-host migration. available only by using the web client.

• VMware - SAN verses server for the guest operating system

  We set up our VMware environment 4 years ago and want to replace the hardware and upgrade to VSphere. We are now part of a large organization and they are questioning our original facility regarding using a San to host Windows Server guests in this environment. They believe that a San is only for storage and VMware customers have to live on a server. I'm looking for confirmation that we use "best practices" by having the OS guest systems on a San, rather than a server. I'd really like something VMware that says to use a SAN and why. It's our Installer; We have 4 servers ESX 3.5 with dual processors core quad, 32 GB of ram and quad port network adapters. The ESX servers connected to the SAN via redundant fiber via HABs connections. The SAN has 6 TB of storage space and we accommodate 24 people from Windows 2003. I say that we have this right and they say I should welcome the guests on a server and not a SAN. My point is why are in charge of the server OS and everything that comes with it as patching and antivirus and multiple HBA when I can get a SAN form HP at equal or lower cost. I just need help to make my case.

  Shared storage is a requirement for features such as vMotion, DRS, and HA.

  It is certainly having a guest on local storage, but what happens if you have a question of host or need maintenance?   If you use a shared storage and you need to host maintenance you can simply vMotion the VMS to another host and there is no interruption of service.   Without shared storage log off the virtual machines or need to spend downtime to migrate them to another host.   If a host goes down, your VM on local storage is down until the host is repaired.  With HA and a shared storage, another host will reboot the virtual machine and it will be online in a few minutes.

• ESXi 4.1 error live migration

  I have 2 servers Esxi 4.1 in a HA cluster with a dozen of VM (Windows and Linux hosts). Due to limited resources, we had to add a server more Esxi 4.1 (spec material for guests shown below). The idea was live migrate virtual machines from existing hosts to the new host. Pretty strange of the virtual machine will not migrate direct and throws the error message "host CPU is incompatible with the requirement of the virtual machine to CPUID level 0 x 800000001 register"edx"...» (screenshot attached).

  esxi1 (hosts in cluster HA)

  esxi2 (hosts in cluster HA)

  esxi3 (new host added)

  3 x DL360 g5 with Intel (r) Xeon 5130 CPU @ 2.00GHz and 4CPU X 2 GHz.

  As a work around, I can poweroff these virtual machines and migrate them to newly added host and switch on. This seems to fix the problem automatically incompatible cpu.

  Now, I'm puzzled to understand whats going on. I'm sure that someone out there had a similar experience and might have answers.

  you need to activate tehcnology Intel VT in the bios. Some manufacturers call it virtualization technology in the bios. Once you turn it back on, save it, then turn off the server and boot to the top. This gives a power cycle to cool off in ready mode of VT.

  Here's the tutorial for Dell server, but it is not far for other manufacturers. http://www.vmwareinfo.com/2009/02/enable-VT-and-EVC-in-Dell-BIOS.html

• Cannot migrate through the required network. Someone please...?

  I've set up 3 ESXi hosts connected via 2 parallel networks. One is a slower network (base 100) on 192.168.12.0/24, and the other is a speed gigabit on 10.1.1.0/24 network. Each host is to have two physical network adapters for each network.

  Home #1 Config is as follows: (also see attached photo)

  vSwitch0 (connected to vmNic0 )-> a

  -Network VM (Machine Virtual Port group)

  -Management network (VMKernel Port) vmk0: 192.168.12.30

  vSwitch1 (connected to vmNic1 )-> a

  -Network SAN (Virtual Machine port group)

  -VMKernel-Special (VMKernel Port) vmk1: 10.1.1.30

  NOTE: Host 2 also has a similar setup with a different set of IP addresses.

  My problem is that when I try to cold migrate a virtual machine from one host to another (in the left pane you see, sound of 192.168.12.30 to 192.168.12.32), he's still doing the migration through the slower network (vSwitch 0). I want to be cold migration through the fastest gigabit set to vSwitch network 1.

  I have not yet tried make clusters or vmotion, because I can't seem to properly configure the network I want to serve. so can you please help me with this? I want to make sure when I do the migration (migration to cold to start), happens through the network of my choice, which in this case is the gigabit network. Thank you very much.

  Hello

  The stream migration cold traffic over the first Appliance for management of the system detects. In your case, there are two, with the slower network, being the first one it finds. There is no way to route based on activity, so that you either the entire network managemernt vSwitch1 or you live with slower speeds. Personally, I'm not sure that I would never have my network of virtual computer on the same link as my device/network management since they are generally two areas of different trust, etc..

• Live migration of HYPER-V Server R2 2012

  Hello

  I have a new Hyper-V 2 built node cluster. Storage is presented through SAN. Live-Migration network, network Public, private network and virtual switches-2 VMS-MGMT. These boxes are hardware identical; HP DL580 G7 with a lot of horses. I am running Windows Server 2012 R2 Datacenter Core on each node. My problem is, I validate cluster, and I get no error at all. This is a brand new clean install, but for some reason any I can only migrate from one node to another and not return without having to reboot a node after live migration. I don't know what I'm going? Has anyone already experienced this? A peer of mine installed the same scenario in a different data center and it does exactly the same thing too. Which leaves me to believe it's OS or hardware related?

  Any help will be greatly appreciated!

• How can I disable the guest user to close the PC while the Admin is connected?

  I'm running Windows 7 Ultimate. I found out how to disable the guest user closing at all via the local security policy, but then they can't stop even if the Admin account is offline.

  To clarify a bit, say I want to give my PC to someone, I usually click on change user and connect using the guest account. In this way, they can't access my account because it asks for a password. I want that in such a case, they should not be able to stop the PC as my admin account is always logged.

  However, if someone booted the PC themselves and use the guest account, then they should be able to close too, as my Admin account has not been connected.

  I'm running Windows 7 Ultimate. I discovered how to disable the guest user closing all through local security policy.

  It is the correct method. It is as robust as it is unconditional.

  If you want to have your cake and eat it the guest account must use a powerful "agent" to perform the functions of judgment. A scheduled task would be such an agent. It might work as follows:

  1. Create a scheduled task that runs Script1 to perform these tasks:
     -Check if the C:\Shutdown\Shutdown.txt file exists.
     -If not, the output of the script.
     -If this is the case, delete Shutdown.txt.
     -Check if there is an administrator session. If so, the output of the script.
     S ' there is no live administrator session, shut down the computer by using shutdown.exe.
     The task must run under an administrator account once every 3 minutes.
  2. Create a shortcut on the desktop for the Guest user calling Script2 for these tasks:
     -Check if there is an administrator session.
     -If this is the case, create a pop-up to inform the user that the machine cannot be stopped.
     -If it is not, create the C:\Shutdown\Shutdown.txt file. The scheduled task will 'see' this file and will stop the machine.

  I tried a lot of suggestion, but delete the file crazy and that's all working again.

  This has proved to contain leads to a difficulty.  Have to admit, when I read everything the first time, several days, I did indeed find it confusing and even the parts that I "heard" (sorta) does not appear to be related to my symptoms.

  It turns out that the answer of JDMICHAL May 17, 2011 contained this:

  (1) C:\Users\Default\AppData\Local\Microsoft\Windows open live
  (2) this directory has two subdirectories with a single file of each. Go into each directory and apply the following:
  (a) make a right click on the file, open the properties.
  (b) click the Security tab.
  (c) it will issue a message: "to continue, you must be an administrative user with permission to view this object's security properties. Would continue you? ». Click on the button continue.
  (d) click on the Add button...
  (e) ' everyone' type in the box at the bottom of the dialog box. Click on "check names"; It should be emphasized the "everyone". Click OK.
  (f) ensure that the new "Everyone" entry "read" and "read & run" check under the column "allow".

  After doing this for two files, attempt to connect to the account. He must undergo.

  The procedure (bascially) worked... Although the different answers on my system differed slightly along the way (perhaps due to the slightly different versions of Win 7?, because I was already logged in as an administrator?).

  In any case, "Everyone" with the read and read/execute permissions adding to these two files seems to have done the trick:
