Speed low migration between 2 esxi host

• VM automatically migrated back to ESXi host

  Hello

  I recently installed and configured a Cluster DRS on vSphere 5 on the customer site.

  In the cluster, we added 5 ESXi host. Four HP DL580 G7 with Xeon X 7560 processor and a HP DL580 G5 X 7460 Xeon processor.

  Apparently the X74xx and the X75xx processors are not compatible for vMotion and DRS is impossible between ESXi hosts.

  I tried to vMotion VM of a loaded ESXi, DL580 G7 host, for DL580 G5 the only customer, but the wizard gave me
  a compatibility error saying that;

  "CPU host is compatible with the requirements of the virtual machine to CPUID level 0 x 1 'ecx' register."

  I tired to use EVC on cluster ma to make compatible CPU but no luck! could not execute predefined EVC profiles!

  I just turned off the virtual machine, so I'd be cold - migrate to the ESXi host.

  Could do when it was off, but when I turned it on it automatically ran on the previous ESXi Host which is held before the migration.

  For me, it was strange! because firstly he moved successfully to the new host of ESXi, but came back on the other after power.

  I have two questions about the scenario above;

  1. why the VM turned their backs on the other host ESXi?

  2. How can I solve the problem of cpu compatibility?

  Thank you,

  ' VCA Can' active br because the cluster contains hosts that lack VCA-compatible equipment.

  Please check the BIOS of the host settings and do 'VT - x' and the 'no. Execute Disable"are both set to"enabled ".

• Migrate between the specific host

  Hello VMware Communiti

  How can I find out in the light of the comments I have a cluster HA I can't migrate. Ore to migrate only between specific host of towing.

  If you want to restrict the VMS to migrate to some hosts there is a work around.

  Create portgroup VM additional network on the hosts that you want to be allowed and connect VM to present portgroup.

• Is it possible to migrate ESXi host between data centers, if so please provide a brief not

  Hi friends,

  1. is it possible to migrate ESXi host between data centers, if so please provide a brief walking distance.

  2 can we perform vMotion and Storage vMotion while ESXi is turned on.

  3. is it possible to extend the VMDK disk while it integrates snapshots in it.

  Best regards,

  Sirot Vijay

  Yes the vmotion and svmotion works but one by one.

  1 - vmotion is posssible to power on State, but you can't svmotion the vm simultaneously. The storage will remain same

  2 svmotion is also possible to power on the State, but you cannot vmotion virtual machine simultaneously. the host will remain the same.

  3 vmotion and svmotion is possible together when the vm is off power. the host and storage can be changed simultaneously on this State.

• Difference of ESXi hosts between analysis of updates and patches of scene

  Hello

  I have two ESXi hosts with round about 700 applicable patches.

  What is the difference between "stage Patches"und"search for updates"?

  Do I need maintenance mode for the scene fixes?

  Kind regards

  Roland

  

  Hello

  Scan for updates will scan the hosts against the basic lines of patch you have attached to them and to report on the status of this host against the base line, so, essentially, Scan for updates will tell you what patches and updates to your departure are absent from the host if the return "non-compliant" or "compliant" if all patches are already installed.  It can also return 'Unknown' or 'Inconsistent' according to the status of the host and other factors.

  Step will basically copy all files to update and patch that must be installed to the willing host for the conversion, which will be more actually to install patches.  Staging of updates to date does not make service, you don't need to put the host in maintenance mode, while the staging, the host must be in service during the reclamation mode.  You can trigger a reorganization without staging, but the benefit of the staging is, first of all, you will reduce the amount of time that your host is out of action because all patches and updates are already in place in anticipation of final approval, which means that the rehabilitation phase is much faster.

  I hope this helps.

• Migrate the replication for patching ESXi host device

  Hi guys,.
  

  
  

  I'm trying to Storage vMotion/migrate vSphere replication device to different host for ESXi patches. I get the following message
  
  "This entity is managed by VR management solution. It is not recommended to edit it directly. Instead use the GPMC for the solution if you want to make changes. You want to proceed. "
  
  I use vSpere replication without the SRM device. What is the best approach to upgrade ESXi host where there is replication Appliacce. Should I just stop then move the unit, or is it possible to move it while it is running?

  
  

  Kind regards

  Hello

  Moving the unit via the technology Vmware is perfectly fine.

  The message/warning you receive is just to warn you that this VM is a critic and you must be careful. The same message if you invoke the power out of this machine.

  Kind regards

• As part of the SAR cert is to have a NW separated between ESXi host required for VMotion or is it OK to use IP for VMotion management, in the execution of Certification tests.

  As part of the SAR cert is "have a NW/dedicated separate between hosts ESXi (on which we GOS) mandatory for VMotion or is - OK to use IP for VMotion management in the execution of Certification tests.»

  Note that the verification passed Test when you use management IP for Vmotion and without a dedicated connection to NW between ESXi hosts.

  Separate dedicated network interface cards preferred. No problem with the test after this change case.

• How can I migrate an ESXi host since a vDS in a vSwitch with NAS storage on vDS

  I need to move some on a vDS esxi hosts to a standard vSwitch to move a new vCenter ESXi hosts

  I have two 10 GB network adapters that manage the ports VM, NAS storage and vmotion.

  Is there a documented procedure to move a vDS in a vSwitch, particularly for migration from NAS storage to a vSwitch?

  Thank you

  Tom

  No, you will need to do this on a per-host basis.

  I really recommend doing one by one, not in a hurry and checking all the networking before you proceed to the next step. Example: after migrating the vmkernel interfaces, check on a ssh connection to the host if it can vmkping the NAS. Before you move all the virtual machines on the host to the switch std, move one and check if the VM networking continues to function. This will prevent errors and downtime.

• Storage vMotion-Direct between ESXi hosts

  Hi all

  It is my first time on the boards, I hope it's the right way to go on this subject.

  I have problems with Storage vMotion, it's not a set up us would use normally, rather than by necessity with the current scenario.

  We have a desktop which has 2 x 5.1 ESXi hosts. They do not have a budget for SAN with the installation of HBA, and it is only a single requirement. I have to migrate virtual machines from one to the other, but with no external storage. I wait with Storage vMotion directly from a local data store to another.

  I activated the software iSCSI on both ESXi hosts

  Created a vSwitch separated with a VMkernal on two physical hosts

  The two VMkernals are on a separate subnet * 172.16.1 and production vSwitch is 192.168.5. *.

  The NIC allocated for the 172.16.1 network. * is both connected to the same physical switch.

  I ping the VMkernal and the vmkping the VMkernal

  Scan for storage again and nothing shows up.

  I used software iSCSI before, for a long time so I'm probably rusty. Dynamic discovery is normally indicated in the SAN to pick up storage, and finds it just local storage on each host itself.

  In this scenario, I told the IP address of the ESX2 VMkernal on 172.16.1 ESX1. * since I have no external storage. I think it is, I'm wrong, but I don't know what else to do to recover local data warehouses.

  Any ideas to try would be very appreciated.

  Thank you

• What is the interval of time between the virtual machine Linux and ESXi host synchronization?

  I have ESX5.0 with a centos6 installed on this linux virtual machine.

  After the installation of vmware for Linux virtual machine tools, I activated the time synchronization between the virtual machine linux and ESXi host through vmware-toolbox-cmd.

  I wonder what is the interval of time between the virtual machine linux and ESXi host synchronization? If I quickly time OS system, when the OS system time will sync back to the ESXi host?

  According to http://www.vmware.com/files/pdf/techpaper/Timekeeping-In-VirtualMachines.pdf:

  By default, the demon checks the guest only once per minute operating system clock.

  However, depending on whether the guest is behind or in front of the result is different. So, please read the section "periodic synchronization" (at least) in the document mentioned above.

• Transfer rate between ESXi host using "Veem backup and FastSCP".

  Hi all

  I have two ESXi host connected with Eth - 1 G ports on an HP switch

  now I'm trying to transfer data between two hosts using "Veem backup and FastSCP" tool

  a 1 MB/s transfer rate is normal? you know a way to improve the performance of the network?

  Note that no collision or inadequacy not discovered on the way to the switch

  Thanks in advance

  Hello

  This work is a line perhaps? If you use VMFS as target, you must double check the block size, if it is the default 1 MB, the maximum size of a vmdk disk is 256 GB.

  The value you got 274878668800 bytes, divided three times by 1024, gives you exactly 256.0007095336914 GB. This is probably the problem.

  PS: I saw your error screencap you come to Italy, visit us on the pages of Italian user :-) group

  Kind regards

• vSphere 4 + ESXi 4: Image using a RDM cannot be migrated to a different host, card held locally RDM?...

  I have two servers ESXi 4.0 and one of vSphere (4.0), their management. These two ESXi hosts can see a LUN on a NetApp FAS2020 and they see it as the same device (if I change the name on the same host, its automatically changed on another host). I have also a larger NFS volume that I use for my VMDK files, and it is on both ESXi hosts. All my guests use the NFS data store for their primary, and several disks use it to a secondary drive.

  I have a specific host to use an iSCSI LUN of the NetApp for its secondary drive. I added it as a Raw Device Mapping (tried physical and virtual), but when I go through the installation program, must I store a map file of the LUNS on a data store. Unfortunately, the single data store, you have an option is the LOCAL DRIVE of the ESXi host. As soon as you start the system and try to migrate, it fails because the second vServer cannot reach the mapping file that is located on the first vServer.

  What I'm doing wrong here... Why can't store the mapping file ROW with the rest of this VMDK and file EXCHANGE virtual servers?

  I think it is because the file pointer needs a block device. You can check KB for details. And Yes, you need another logical unit number (type vmware) and create a VMFS on it to store the pointer files.

• Share of CPU between ESXi hosts in a cluster?

  Is it possible to configure a cluster with a pool of CPU resources such as all CPUS of all ESXi hosts in the cluster are in the pool and if a virtual machine starts using more CPU that's current host has it can draw another ESXi host CPU to deal with?

  A virtual machine can use CPU only from the host where the virtual machine works... There is no way to allocate CPU of multiple hosts to a single virtual machine.

• Impossible to withdraw, migrate, etc., VM on the ESXi host

  Earlier, the room of my loss of cooling infrastructure hosting servers suffered vSphere causing several ESXi hosts to closure without notice due to excessive heat.  Needless to say that the results were chaotic.  While I recovered/restored most of the systems, a problem seems to persist.  It is a virtual machine that is impossible to remove, move, etc. due to locks on files active.  The option in the .vmx to "Add to the inventory" file in the data store is also disabled.  However, this virtual machine is not displayed with a "vim - cmd vmsvc/getallvms" command.  In fact, investigating the locks on files, it doesn't appear with a ' vmkvsitools lsof | grep VM_Name command"and no result back with a ' ps | grep VM_Name command.  The host in question has also been restarted and updated (5.1 update 2, Update 3) so a simple reboot does not clear the locks.  So, the question is; How can I get rid of this virtual machine so I can properly re - add to vCenter?  Any help would be appreciated.

  Then just do a kill-9 20156 and you are all set - this kill everyone and goes out by the force of the virtual machine and your hair will be free
