VMotion between EVC cluster and native cluster

• vMotion between 4.1 and 5.5

  Our production now runs on a cluster of 4.1 and our old SAN NAS fiber with VMFS3.  We have 3 new servers, not used now in a cluster of 5,5 with a new empty SAN NAS fiber with VMFS5.  Even though these two groups have vMotion networks on the same subnet, I do think fast vMotioning without a live VM from the old to the new cluster is possible, mainly because 4.1 must be fixed on both.  Even with a disabled virtual machine I don't think vCenter & vMotion is any help and backup & restore, it is called for.  Am I right on this?

  I think we should do is: forget the new cluster, join the new 5.5 servers in the old cluster, use vMotion to migrate all virtual machines to the 5.5 servers but always located on the old SAN, cut loose the old 4.1 servers, add the new data store empty VMFS5 and storage vMotion, virtual machine for the new San (everything is done with running virtual machines).  Not quite sure if 4.1 servers and 5.5 will work in the same cluster, but I think they can.  Former processors are AMD Opteron, and new Intel Xeon processors.  How is this sound?

  Thanks for the tips... Lyle

  In this case, you can do the following:

  1 create a new cluster on the same vCenter server that contains 5.5 hosts

  2. ensure that the new host can see the old SAN (you can also connect a host that can act as an intermediate host)

  3. cold migrate virtual machine 4.1-5.1 host

  4. power on the VM and check

  5. use storage vMotion to migrate from the old san again san

• VMotion between single core and dual core

  I have 2 Dell PE 6850's and according to the table of vmotion for cpu dell, they are compatible. But now the question is is there a problem if one of the servers has 4 core processors and the other has 4 duel procs and HA works correctly?

  If the processors are compatible vmotion, then you will be fine.  ESX is NUMA aware, so that he knows the difference between a core and a CPU socket and the implications of the memory of the two.

• vMotion between PE2950 lll and R710?

  I have a Dell PE2950 with intel e5430 2.60 Ghz model 23-6 lll step by step and was hoping to add a R710 with 5660 x 2.8 Ghz for the mixture but I'm concerned I won't be able to vMotion because of the processor

  The PE2950 is running esx 4 but am planning on upgrade to ESXi

  Am I right to worry?

  Are there ways to work even when vMotion?

  You should put the two host in a cluster and select CVS with level "Core 2 45nm"

• Differentiation between virtual App and Native application

  Hello team,

  Wanted to know how the difference between a virtual application and the local physical application. Y at - it any key or variable registry system available which can help identify the virtual when its application was managed by the end user during execution. Are there any files and registry system for virtual applications?

  For example: from online Cameyo/ThinApp/spoon streaming server, I downloaded firefox.exe virtualized and thus downloaded mozilla's physical firefox.exe and installed (Version remains the same for the application). For physical firefox.exe there is the registry key or a variable system available.

  How about the application virtual firefox.exe, will there be an entry in the system registry or files during its execution?

  If Yes please share the details.

  You have different ways to determine if the application was packaged with ThinApp.

  • When you run a ThinApp application, you have the popup appears above the system tray in the lower right corner with the name of the application and "vmware".

  

  • When you have installed the application with the MSI or save it with the thinreg utility, you have created registry keys:
    • If installed by user: HKCU\Software\Thinstall
    • If installed by computer: HKLM\Software\Thinstall
  • A sandbox is also created for the application during its first execution in %APPDATA%\Thinstall (default location).
  • If you run the package with the setting -ThinstallVersion. For example, in a CMD prompt type: package.exe - ThinstallVersion.

  You will get the ThinApp version used to build the package.

  

  • If you need to determine if the application was packaged with ThinApp of more "automatic" or "script", use the software ThinApp SDK. Look for example here: http://www.horizonflux.com/getting-started-with-thinapp-sdk-and-powershell/

  Sorry - I should have mentioned that in my last post. Also, check that your guests are under tension when you finally activate CVS on your cluster.

• VC4.0 usable vmotion between esx 3.5 and esx 4.0?

  VC4.0 usable vmotion between esx 3.5 and esx 4.0?

  Yes, you will be able to vmotion between 3.5 and 4.0

  Just leave your comment "out of date" tools until all ESX versions are on their final construction, then upgrade the comment tools and virtual hardware

  http://KB.VMware.com/selfservice/microsites/search.do?cmd=displayKC & docType = kc & docTypeID = DT_KB_1_1 & externalId = 1003212

  New features in each generation of processor. However in order to migrate live virtual computer, the CPU characteristics presented to the virtual machine must be equal on the source and target host does not cause problems (such as BSOD). The different EVC baselines hide or reveal certain CPU features to the virtual machines that are common for all processors in the cluster. Table 1.1 in the article you mentioned some of these CPU features.

• EVC cluster creation / migration hosts him / minimal disruption VM

  I am reshape my somewhat environment and need a bit of advice.  Currently, I have 2 ESX hosts in a non - EVC cluster and built a new blade server.  The new blade and 2 hosts will work together in a cluster active CVS.  I know that I have to run my EVC cluster "Intel Xeon Core 2" mode.  All 3 hosts will support this mode.

  The News / 3rd cluster is sitting in his own vCenter, a VCA-activated cluster (in mode above).  Has no running VMS, it is already configured with network access and storage that matches that of the 2 existing/production hosts, which are currently managed by another instance of vCenter (but I am moving them out of this instance of vCenter in this new EVC-activated, to join the new blade.

  All hosts running ESX 3.5 U4.  vCenter is 2.5 U4.

  BIOS on guests must be modified to memory XD in so that they can be used in an EVC cluster, so I know I need to stop at SOME point to get them in the cluster active CVS.

  I have an idea on how to address these requirements, with a big goal is NO interruption of service for running virtual machines.  VMs can be migrated to a new cluster, EVC-activated, coming from an old cluster VCA not compatible?  Most all current VMs based on Intel some running already in reference "Intel Xeon Core 2" EVC mode or I'm just kidding me and must arrest all of them at some point after they "seized" a VCA-activated cluster?

  How would you do to this migration between vCenters and Clusters?  I think I can use 'Disconnect' the first vcenter (to at least avoid having to go into Maint Mode and then 'delete' of the first cluster/vCenter database)... also, I'm looking for the most logical get "here" to "there".  Thank you.

  I see that the problem of different vCenters/Clusters is resolved.

  What you need now is to know if you can VMotion between two ESXs with different processors. Before existing VCA, I have had... and had NOT a few difficulties doing this. It is not a problem when DIFFERENT pCPUs have the SAME GAMES of INSTRUCTIONS (SSE3, SSSE3, SSSE4 and so on...) Even if the sets are different, I was able to mix the MASK of CPU management options, which are by VM (thing that I didn't like... There should be an option to change this on a same CLUSTER basis or an ESX!).

  I recommend you to test for differences between the sets of instructions of the Jepp of two ESX with this tool, I think it is the best out there:

  http://www.run-virtual.com/?page_id=155

  If the sets of instructions are different, you have a problem, because you have to find the bits change in the MASK of CPU options in each virtual machine... and who needs a reboot, too. I think they will be different, because more recent pCPUs with FlexMigration (VCA compatible Intel processors), simply because they are new they surely have a new instruction set (perhaps SSSE4)

  Good luck!

• VMs migration of a non - CVS to EVC cluster cluster

  Hi all

  I entered in an environment that has only one lit 9 hosts without EVC group:

  Host	Processor family	Processor	Version ESX (i)
  Host1	Penryn	Xeon E5450	4.0.0 update 2
  Host2	Penryn	Xeon E5450	4.0.0 update 2
  Host3	Penryn	Xeon E5450	4.0.0 update 2
  Host4	Nehalem	Xeon X 5550	4.0.0 update 2
  Host5	Nehalem	Xeon X 5550	4.0.0 update 2
  Host6	Nehalem	Xeon X 5560	5.0.0 Patch1
  Host7	Westmere	Xeon E5630	5.0.0: no patches
  Host8	Westmere	Xeon E5630	5.0.0: no patches
  Host9	Westmere	Xeon E5606	5.0.0 patch 6

  
  I'm looking to create two groups, one for the three hosts of processor Penryn (dev) and a separate for six guests Nehalem/Westmere (prod).

  If I put one of the hosts Nehalem in maintenance mode, remove the current cluster and place it in a new cluster with EVC lit with the CVO 'Nehalem' mode, I will then be able to vMotion VMs to two other guests the current to the new EVC cluster cluster Nehalem activated?

  I understand that the virtual machines on the hosts Westmere must be powered off before their migration to the new Nehalem EVC cluster but can I Motion VM hosts to the new Nehalem Penryn cluster virtual machines?

  Also the guests of Nehalem contain two types of processors: X 5550 and X 5560. This would impact on virtual computers fast vMotioning of a non - EVC cluster to a new cluster of Nehalem VCA?

  TIA

  "If I put one of the hosts Nehalem in maintenance mode, remove the current cluster and place it in a new cluster with EVC lit with the CVO 'Nehalem' mode, I will then be able to vMotion VMs to two other guests the current to the new EVC cluster cluster Nehalem activated?

  Yes. You go from Nehalem, Nehalem, no problem.

  "I understand that the virtual machines on the hosts Westmere must be powered off before their migration to the new Nehalem EVC cluster but can I Motion VM hosts to the new Nehalem Penryn cluster virtual machines?

  Yes. As long as the instruction set is lower or equal to Nehalem, you can do.

  «As hosts of Nehalem contain two types of processors: X 5550 and X 5560.» This would impact on virtual computers fast vMotioning of a non - EVC cluster to a new cluster of Nehalem VCA? »

  As long as the non - evc cluster is Nehalem(or lesser), it shouldn't be a problem. Everything you do with CVS is hide which instruction sets may be available to virtual machines.

• Active EVC cluster will not allow guests to reach...

  Recently, I installed a new vCenter Server 5 (vCenter 4.x running on a 32 bit OS then upgrade was not an option-fresh install)

  I had 1 main cluster in the datacenter with HA and active CVS. All 10 guests were very well in it.

  However, when the new vCenter Server has been up - and after having removed the old vCenter data center, when I went to add the host to the cluster (same as before active EVC mode) 6 guests joined very well, while the other 4 could not.

  Everyone knows this? Just a reminder:

  new vCenter Server 5

  all 10 guests were in an EVC cluster well

  4 of 10 guests will not join the same cluster...

  Thoughts?

  Another question regarding VCA - if I point the old vCenter DB, the new vCenter server will this cause problems because a new database created for the new vCenter? How should I approach the issue?

  You can't do it now, you can not connect vCenter 5 dB in the version of vCenter 4, different schema, tables etc. as I said in my previuos reviews, you must migrate to vSphere with DB 5

  1. Start vCenter old (I hope that you did not remove or disconenct any server from there, right?)

  If you do not make any changes to the OLD vCenter vCenter should be able to connect to the return ESXi hosts and apply all the settings (including the CTS)

  And Yes, I take off (unplug the old vCenter servers... so I guess that reconnect the old Server vCenter is not possible.)

  If you simply disconnected the old vcenter ESX hosts (not deleted) you should be able to connect to vCenter old with old settings, but as I said earlier, I don't know what will happed with a VCA base (because you creted clusters with different CVS on new vCenter.)

• Changing the Mode of EVC Cluster for guests of Intel

  We cross a turnover of rental for our ESX host that puts out some old CPU architectures. Once we get rid of these hosts, we will be able to raise our EVC Cluster mode.

  (1) once ready, are there special precautions to take before changing the Mode of EVC Cluster? Then I just change the setting?
  (2) when the VMs will begin taking advantage of the new architecture CPU (a reboot will or VMs must they be turned off)?
  (3) any question with VM do not be put off for long periods of time after the VCA mode change?

  (4) all other things to worry about?

  If I raise the EVC mode, virtual machines will be able to access the new features available in this mode?

  Is that you turn off and then turn on the virtual machines. A reboot of the guest operating system is not enough. A virtual machine determines which functions are available to turn on and cannot access all the new features that are added until the power is turned off.

• vMotion between a Quad Core computer host and a hexacore

  Is it possible to vmotion between a double x 5570 and double a 5670 x server?

  Thank you!

  Hello.

  Yes, you need to activate the VCA mode as described in KB 1003212 for the 5570 and 5670 to work together.  Regardless of the number of cores.

  Good luck!

• vMotion between versions and licenses

  I have a question about vMotion in vSphere 4.1.  It is primarily on licenses, as I know technically what I'm asking, it's doable.

  With the inclusion of vMotion in Standard licenses, can run a mixed environment (eg. Enterprise and Standard licenses) and vMotion between hosts with different licenses?

  For simplicity, assume that the environment is running 4.1.  Although if you know, could you please indicate if it would work between versions (eg. between 3.5 and 4.1 or 4.0 and 4.1).

  Thank you.

  
  
  The answer you are looking for is + 5.23.2

  Yes.  As long as you have licenses vMotion on all host ESX (i), and you meet the requirements of vMotion (shared storage, CPU compatibility, network, etc.) whereas there should be no problem.  Remember that if a mixed environment of VI3 and vSphere4 hosting, do not upgrade the comment tools.
