• Regarding vSphere VCA and vMotion

  Hi all

  I have several questions about vMotion and VCA, can anyone help?

  1. If I mix several types of CPU (from the same supplier of CPUS) in a vSphere without EVC cluster active, what will happen? can I vMotion VM on the host?

  2. I can vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Assume that CVS is not activated on the two groups.

  3. can I vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Assume that CVS is not enabled on the source cluster, but active on the destination Cluster.

  4. I can vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Suppose that EVC is enabled on the source cluster, but not active on the destination Cluster.

  5 can I vMotion of virtual machine of a stand-alone ESXi host on an active EVC cluster? Assume that the CPU is the same.

  6 the KB "EVC and CPU compatibility FAQ" below, if we disable CVS on a cluster, the virtual machine can only be migrated to hosts with CPU even or more.

  Why virtual machines is only able to move to other ESX/ESXi hosts that are in the same generation of CPU or more? It's in front of my knowledge.

  VMware KB: EVC and CPU compatibility FAQ

  What is the impact on vSphere features of the Cluster when I turn off the CVS mode?

  To turn off the CVS on a cluster mode, it affects vSphere Cluster features in the following ways:

  • vSphere HA (High availability): vSphere HA is not affected because of the cyclic power failover virtual machines when you start on a new host. This allows the VM picking up the new ID CPU and it allows to start without problem
  • vSphere DRS (Distributed Resource Scheduler):
    • vMotion: virtual machines is only able to move to other ESX/ESXi hosts that are in the same generation of CPU or more. If the DRS is configured for fully automated, this can result in virtual machines, eventually migrating to hosts on the cluster with the generation of CPU more old where they cannot be moved via vMotion on different hosts with a newer processor generation.
    • Storage vMotion: virtual machines are able to be moved to Storage vMotion with EVC mode disabled in a cluster
  • Location of the pagefile: it is not affected.

  Thank you.

  1. If I mix several types of CPU (from the same supplier of CPUS) in a vSphere without EVC cluster active, what will happen? can I vMotion VM on the host?

  (a) you very well can vMotion virtual computers between the hosts with identical processors within the cluster.

  (b) for vMotions on different hosts, it depends on CPU instruction set parity and orientation, i.e. the older generation-> new generation or vice versa.

  Consider the following: when a VM is turned on at the start, it is presented in UC sets from the physical host, where it has been turned on. It must keep these settings until the virtual machine is turned off, any host it is migrated to in the meantime. Therefore, as long as a host provides these CPU instruction sets, it can be vMotioned it. Further instructions on new hosts games is irrelevant for this and just hidden-away of the guest. So old-> new should be fine, but new-> old most likely will not work because the virtual machine works with games of additional CPU instructions that only is simply not supported by the older physical processor.

  2. I can vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Assume that CVS is not activated on the two groups.

  Yes, generally vMotion shall function in older generations of CPU to the most recent, the same common CPU instruction sets are supported by the destination CPU host and enabled in the BIOS.

  3. can I vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Assume that CVS is not enabled on the source cluster, but active on the destination Cluster.

  4. I can vMotion VM Cluster with older CPU for the Cluster with more recent CPU? Suppose that EVC is enabled on the source cluster, but not active on the destination Cluster.

  Yes, the same general vMotion as explained above requirements. If CVS is enabled on any, both or a cluster does not matter (of course provided a configured VCA level is not reverse the physical hardware capabilities 'new' and 'old').

  5 can I vMotion of virtual machine of a stand-alone ESXi host on an active EVC cluster? Assume that the CPU is the same.

  Yes, the same general vMotion as explained above requirements. A stand-alone host is exactly the same thing treated as a non - active EVC cluster.

• VCA mode - vm vmotion level lower than the level when turned on?

  Hi all, trying to get a definitive answer on this one there...

  Assuming that ESXi 5.1 u2, if you have two clusters, a set to VCA = Westmere and a game to Haswell, could you vmotion a powered on virtual machine cluster (Westmere) at a lower level to the upper level (Haswell) cluster, or must it be turned off?  I realize that, to take advantage of the latest processor have together, the virtual machine power cycle is required, but I didn't understand if you can vmotion it when turned on?

  Thank you! ~

  Yes, you can vMotion as a virtual computer to a host of generation more recent CPU very well provided that it contains of identical CPU instructions sets that older CPU's (the host has them enabled in BIOS too). You can vMotion that their return to guests because as long as you do not have virtual machines powered bike, they will continue to work with the old base EVC.

  I also vMotioned VMs hosts generation Nehalem to new hosts of Sandy Bridge earlier without problem.

• VCA compatibility between processors 2600v2 E5 & E7-4800

  We want to add processors Intel E5-2600v2, Ivy Bridge, to a cluster of u1 vSphere 5.5 using E7-4800, Westmere processors.

  When checking the following link,.
  http://www.VMware.com/resources/compatibility/detail.php?deviceCategory=CPU & ProductID = 64 & VCL = true

  Enhanced VMotion does not seem to be supported for the Ivy Bridge in Westmere processors.

  VMotion strengthened capacity Modes: Intel Merom generation

  Generation Intel® Penryn

  Intel® Nehalem-generation

  Intel Westmere generation

  We read this information correctly?  Westmere and Ivy Bridge CPU VCA not compatible within the same cluster 5.5u1? If there are documents to support that they are supported, can you give the link? Thank you.

  According to the specifications of VMware Compatibility Guide: cpu (you can select both processors and compare them), Intel Westmere is registered to two processors as a mode of EVC supported.

• VCA - VTC study material

  Where can I find reviews of practice for the vca - VTC? I used the test of practice on the vmware Web site but they cross only maybe 20 different questions. Some other materials are also good study that will help me to pass the exam?

  The practical issues are not the same that on the real exam - he would "practice" a little too effective if they were the same.

  From what I've read several times, the basic training is pretty complete in terms of exam item coverage.

  For all VMware certification exams, I would recommend that you read the action plan which covers the objectives of the review - and if you feel you need to do additional reading/study/preparation you will know the specific areas, for that you will need to do this.

• VCA - VTC confused period?

  Hi friends,

  I worked on Vpshere ESXi 5.5 U2 for 9-10 months so decided to go to this level starter VCAD510 review: VCA - DCV (without coupon) cost me about $ 95.

  I asked him properly in internet, there should be 50 multiple choice questions and delay of 75 minutes .

  But on the peasonvue portal, show length examination 120 min.

  Why is it so? why more than 45 minutes?

  I get more questions then?

  Help out me

  I did all the basic components of vsphere:-5.5 ESxi, Vcenter Server, Vmotion, motion of storage, vconvertor, HA, DRS, FT, storage DRS VSANS, VLANS, DPM, EGGS/OVF, groups snapshots/cloning/templates, Port, security policies, traffic shaping, consolidation of network cards, VCB, DPM, virtual appliances, Vswtiches, Distributed switches, VUM, VMware tools, Orchestrator, Site Recovery Manager, Configuration Manager, Vcenter Vcops VCB , Horizon view intro, Director intro vcloud.

  Should what products/features I study? suggest me.

  Screenshot of personvue of Portal exam details, is attached.

  Thanks in advance.

  The regular commitment lasts 90 minutes in total - 75 to answer questions and 15 minutes to complete agreements and demographic issues.

  You've got another 30 minutes to answer the questions, you are in the exam in a country where English is not the first language - you can see that at the bottom left of the screenshot you posted.

  So you will have 105 minutes to answer the questions, as well as 15 minutes to complete agreements and demographic issues.

• VCA serious question in a cluster after adding servers active DRS blades M630 Dell

  Hi guys,.

  I hope that you will be able to help me with this strange question that I feel right now.

  A couple of details first on our environment:

  • vCenter 5.0 U3
  • ESXi 5.0.0 - 2509828
  • 6 guests active DRS cluster
  • 4 hosts are Dell M620, E5-26XX v2 processor blades
  • 2 hosts are blades M630 Dell with processors of E5-26XX v2
  • VCA mode is currently set at "Westmere".
  • All ESXi hosts are fully patched using AUVS

  Before adding the new M630 blades to the cluster it any of the issues with the DRS or VCA, outside the constraints of resources, and the 4 blades M620 we are able to correctly migrate the virtual machines back.

  I could add the M630 blades to the cluster without problem and without errors or warnings have been issued. A week or so later, I noticed more deviations of DRS desired on the cluster. More inspection I noticed that quite a large number of virtual machines showed N/A beside VCA mode and I was not able to migrate them to any host on the cluster.

  Thinking it could be a bug of sorts, I turned off all the virtual machines in the cluster and run a script that resets the CPUID at default. In addition, as a measure of precaution, I restarted the vCenter server and ensures that the database has been effective. The hosts are synchronized time with an NTP source and fits perfectly on both hosts.

  After feeding all the VMS, I rebooted the M630 servers and inspected the BIOS settings to ensure that virtualization and NX/XD is enabled. With all virtual machines powered off, I was able to change the levels of the VCA to any available without warnings setting.

  When everything has been turned back on I noticed a strange behavior in the cluster.

  Virtual machines that are running on M620 blades show the right level of CVS and I am able to migrate them to all servers in the cluster. Once that they migrate to the blades M630, VCA state change s/o and I am unable to migrate anywhere, not even the other M630 blade in the cluster.

  The error that I am shown during the verification step is:

  The operation is not allowed in the current state of the connection to the host. Host CPU is not compatible with the requirements of the virtual machine to cpuid level 0 x 1 host bit ' ecx' register: 0000:0010:1001:1000:0010:0010:0000:0011 required: x 110: x01x:11 x 1: 1xx0:xx11:xx1x:xxxx:xx11 inconsistency detected for these characteristics: * General incompatibilities; see section 1993 of possible solutions.

  Dig deeper in my investigation, I came across this KB: 1034926[1]

  I checked the M620 user guides and the M630 and parameters mentioned in the KB should be enabled by default. Unfortunately, I have no way to check the BIOS settings because I can not all M630 blades enter into maintenance mode without turning off the virtual machines running on them and another maintenance window one day after previous, we're going to be deprecated. In addition, the error is not the same as that of the KB and my goal is to collect as much information before entering another window of maintenance requiring downtime.

  I hope that you will be able to provide any new perspectives or opening my eyes to things that I may have missed.

  Thanks in advance.

  The processor in this system is a v3 E5-2660, not an E5-26xx v2.  ESXi 5.0 doesn't know how to use the features of this processor FlexMigration.  I think that the first version of ESXi to support this processor is ESXi 5.1U2.

  Unfortunately, I do not see a workaround for ESXi 5.0 solution.

• VCA Mode change

  Hello
  I'm downgrading to Westmere EVC mode to conform to the old generation of host we add to the cluster.

  To do this, I currently have two clusters created, in production and two hosts using sandybridge.

  the second group has a central server inside and westmere generation.

  I am aware of the procedure found here:VMware KB: VCA allowing on a cluster when vCenter Server is running in a virtual machine

  My question is, rather than quick vMotioning of all hosts another machines.  is it possible to close all virtual machines on a host, set mode now, disconnect the host, move it to the cluster Westmere allow it and then put on all virtual machines?

  I know that I'll still have to disconnect and reconnect my vcenter server, but I would like to avoid having a large amount of machines to vmotion if I can find some downtime to stop all.  and make them move with the host.

  This idea is possible?

  So if I understand what you really want is the future VMs with the host computer, then when you add the host to the new cluster and power them they will run under the new EVC Mode but you essentially in bulk installs what you wanted?

  If so, I did what you describe a bunch of times before (especially during migration between vCenters and want to go to the host and all virtual machines), what I would recommend however keeps the VMs powered on. Disconnect the host and then remove the vcenter. Once removed from the cluster and vCenter connect through thick client and put all virtual machines. Then add it to vCenter, in the cluster you want to and feed the VMS and you would be actually resigned these VMs in bulk.

  Conversely, you can turn off the virtual machines and keep track of those you want to migrate, put the host in maintenance mode and move it to the cluster that you want and then get out of maintenance mode, cold migrates virtual machines and then turn on. I think that this option will be a little easier.

  However, to disconnect a host and removing vcenter will make virtual machines with it, that looks like what you want to do...

• AutoDeploy on VCA 5.5

  I am fighting to get auto deploy work on VCA 5.5.

  ESX server starts using PXE, but could not get a picture of ESXi, see screenshot below

  The TFTP server is accessed through a web browser https://192.168.2.21:6501/vmw/rbd / and https://192.168.2.21:6501/vmw/rbd/cache/url display all downloaded files.

  I created a rule of deployment with the - AllHost

  So why does not the ESX ESXi image?

  
  

  

  Solved the problem, it's the tramp file in the folder tftpboot on the VCA.

  There the VCA FULL domain name, but during the boot PXE DNS is not used even if its in the DHCP options.

  Changed the domain IP address FULL name and it works like a charm.

• Expiry of VCA - VTC of cert?

  So I can see that VMware did the VCP cert a contract of 2 years (since May of this year I think).  However, I don't see anything on the VCA - VTC does - this it an expiration of the certification too or did an a cert of time?

  Thank you.

• VCA - VTC and VCA-Cloud, working on 550 VCP past.

  As the title says, I went VCA - VTC and VCA-Cloud.

  It discourages me that official VMware courses don't cover everything in the master plan and was looking for a study guide or book that contains everything you need to study to succeed VCP550 review (in addition to the official documentation of VMware).

  Would you recommend the Mastering VMware vSphere 5.5 by Scott Lowe and Nick Marshall as sufficiently ? study material I fell on it and it seems fairly complete.

  Thank you.

  Shameless self-promotion here - my book from Sybex has been updated to cover the exam VCP-550. It covers every single review objective, but accompanying the book Mastering and official documentation of VMware would certainly help prepare you even more. Good luck for the VCP!

• VCA mode disabled / vmotion work?

  We have 2 groups of ESXi at our facility for vSphere, vSphere is version build 5.5U1, currently most recent available.

  Group 1 has Intel Xeon E7540 UC.

  Group 2 is brand new and uses recently published processors Intel Xeon E7-4860 v2.

  VCA is currently disabled on the two groups.

  Athe's systems are listed in the VMware compatibility guide for our latest version of vSphere.

  I expect this Setup to be able to live vMotion of virtual machines from the old to the new cluster without the use of CVS on either, but I assumed that the migration back to group 1 would require cluster 2 to affect the level of reference Intel EVC appropriate (Nehalem in this case).

  It turns out that I am able to migrate VM direct in both directions with no apparent problems (so far), with EVC mode disabled on both groups.

  Is an expected behavior or if ESXi/vCenter is somehow misreading? CPU compatibility (perhaps because the E7-4860v2 are a very recent model) or some other issue that could lead to problems with these migrations?

  This is normal unless you have turned to bike the VM on the new hosts.

  If a virtual machine has been powered - on on a former host and is migrated to the new cluster, it does not change the current features of the virtual machine CPU runlevel. He will continue to work with the old CPU features on the new host and is therefore able to migrate the old new host without problems, or additional AIDS such as CVS.

  However, if stop you now migrated virtual machine and power it on again on new hosts, the virtual material will apply the new host CPU capabilities (or the level of EVC of cluster, but you do not apply any) and you will not be able to migrate the computer virtual return to the armies of the former cluster.
