• 5.1 ESXI host disconnects the vcenter, when reconnected SSL fingerprint has changed.

  I'm having a strange problem with only 1 of the 5 hosts connected to a cluster inside of vcenter. A host disconnects randomly vcenter.

  I right click on the host and select Connect. I get the default value to the warning that 'reconnect a host will replace any change in management of resources that have been made directly on the host... ". ». I select Yes.

  Then, I get an error

  The authenticity of the host SSL certificate is not verified. This option is to close.

  I am taken to the add hosts Wizard. where can I enter the password IP and root to add the host to the cluster.

  Now, I get a security alert:

  It turns out that the problem is that our agile took place of the intellectual property that it wasn't supposed to and it's a double that esxi host IP. Very strange behavior. But it's the solution.

• 5.5 ESXi hosts disconnection of the vCenter 5.5.0b

  Good evening.  I recently deployed some new hosts HP BL465c G8 running the HP OEM install ESXi 5.5 (not the one just released 02/18) and the two hosts have been disconnect from vCenter four times in the past week.  I can sometimes connect to the host via ILO and restart the vCenter agent, but more often without having to start the host hard.  In addition, one of the VMFS5 content of the data store disappeared and the virtual machines residing on this data store have declined because the hosts could not find the configuration of the virtual machine files. Strangely enough, the data store showed spaced used and I could see all the directories within the CLI, but not vCenter client or Web-based Client.  I have two tickets to windows with VMware from HP support team, but I wanted to know if someone had a similar problem.  I'm tempted to rebuild with the latest OEM installation or rebuild as 5.1 or 5.0 if version 5.5 is not fully cooked.  Thank you.

  The issue proved to be the OEM HP install and specifically the pilot v1.1.7 for HBA QMH2572 adapters that it contains.  We have rebuilt our 5.5 ESXi hosts using installation OEM HP published 02/14 (contains recommendations
  v1.1.12 pilot) and that solved the problem of stability.

• 5.1 ESXi host disconnects

  One of our guests 5.1 ESXi 4 disconnects the VC. All the virtual machines on this host seem to work just fine however I can't do simple things like fast vMotioning all vm it. An attempt led to a vmotion taking an hour than to throw an error of something like its take too long.

  I spoke with vmware support, and they say that the problem is related to one of my volumes in my SAN. I have a PS6110E EqualLogic and the firmware and the firmware of hard drives are up to date.

  When I ssh host and cd to the directory of Volumes and try to list the contents of the directory, it crashes and I have to open a new session in Putty. When I go in the volumes directory and replace the directories by a known volume of good, all right. I can see its content very well. Opening upward the Group Manager indicates the volume of the suspect as having enough available disk space and there is no alarm. Access to command line with this volume name, however, results in a lock upward.

  VMWare support says I have a problem with this volume and that seems to be the case, but while I wait for a response from support, I thought I'd see if someone might have any idea what I can watch in the meantime.

  Thank you

  Dave

  The problem had nothing to do with the SAN, it turns out that. Apparently, there was a sort of hang up handshakes between the host and the VC. I had a difficult start to the host and restart the VC too to restore the handshake between the two. All right.

  Thank you

• Connecting directly to ESXi 5.1 for Windows XP fails after upgrading to update 02

  After that night at ESXi 5.1 Update 02 update

  I get the error:

  A unknown connection error has occurred. (The client may not send a request to the server. (La connexion sous-jacente a été fermée: une erreur inattendue s'est produite sur un envoi.))

  I connect from a XP client, I googled this problem:

  which is (I think), but the solution is for vCenter. How to solve without vCenter.

  Welcome to the community,

  Although the article mentions only version 5.5, you can try and see if http://kb.vmware.com/kb/2049143 will help.

• View Connection Manager is unable to connect to vCenter after upgrade to vCenter 5.0

  Our upgrade to vCenter Server 5.0 went smoothly and that our environment is transferred to ESXi 5.0.   However, since the upgrade our environment view seems not to be connected to vCenter.  If I go to view administrator > Configuration > servers and change the entry for our vCenter Server I get a connection failure message when you click "OK".

  I checked that the username and password specified to connect to vCenter administrator mode are correct.

  4.6 and earlier versions is not supported and will not work with vSphere 5 (look on the VMware compatibility matrix). I am bitten by this before so I checked that before even thinking about updating to ESXi 5. You need to wait seen 5.0 for compatibility with ESXi 5.

• Can no longer add ESXi host to vCenter but OK VI Client connects

  I removed an ESXi host in a cluster on vCenter. Now when I try to add the host (whether for the cluster or stand-alone) the add hosts Wizard appears and has the correct information, but when I cliquerai on closing, that nothing happens for a few minutes, then I get the error:

  Unable to reach the specified host... Maybe it's because this host is not available on the network, there is a problem with the network configuration or management on the host services do not react.

  However, I can connect to the host directly with the VI client and which works very well, even though the events tab displays "VFAT: 2583: Possible FAT Corruption." My copy of ESXi is on a flashdrive in a HP Blade.

  I tried to reboot the host, but it makes no difference. Several of the responses to other users of similar problems is recommended to perform "service vmware-vpxa restart" on the host, but this does not apply to ESXi. I also tried to restart the vCenter, but that makes no difference either.

  Any ideas?

  Thank you

  Will be

  Download iso hpvm-recovery on HP site and reinstall ESXi on flash drive.

  UPD: Yes, as Neil said, check your key USB HP if you bought ESXi Embedded. If you have the Green key aluminum, require the replacement of HP. And then, you definitely have to download iso that I mentioned above

• VM doesn't qutoboot upward after the restart of the ESXi host

  Hi all

  I environment, there is only a single Cluster. The Cluster has an ESXi host. all virtual machines including vCenter VM are resides on the ESXi host. When I reboot the host can all VM does not start?

  For comparison, there is a different environment, there are two Clusters (Cluster 1 and Cluster 2) in vCenter, Cluster 1 has two hosts ESXi Cluster 2 has only a single ESXi host. vCenter runs on the ESXi host residing in Cluster1.

  When I reboot the host residing in Cluster2, all virtual machines may start automatically.

  is that any expert can explain the difference? Why single environment can auto boot VMs when both of these environment has a host to the Cluster and cluster activate HA service?

  environments are executed at the ESX5.5.

  You will need to check the box allow VMS to start and stop automatically with the host system and then change the setting on the edit tab, and mention what needs to be done for each machine.

• Attempt to start an ESXi host nested of Windows Hyper-V on Windows 8.1

  Hi guys,.

  I would like to start nested 5.5 ESXi hosts in my 5.5 vCenter environment.  I did successfully using 10 Workstation, but I'm having problems trying to do using Windows Hyper-V running on Windows 8.1.  I created a few test servers and tried to start, receive all of them successfully the IP addresses and downloading the image, but they cling to the «travel modules and updated the kernel...» »

  

  If somebody has got away?  Any suggestions?

  dbutch1976 wrote:

  As described earlier in this thread, the host crashes to "move the modules and from the kernel.

  I don't think that the host crashes in fact at this point.  Since the FADT ACPI under Hyper-V has revealed that the VGA is not available, the output is redirected to the serial port.  If you can complete the "blind" installation, you should be able to get on the rest of the installation while providing the necessary responses.

  The question is why the FADT ACPI under Hyper-V claims that VGA is not available, when it is clearly.

• Retrieve message to ESXi host Summary tab "Configuration issues."

  Using VMware Perl SDK API, how to get the message of 'Problems of Configuration' tab summary ESXi host?

  For example, I have an ESXi host disconnected from the cluster, and in the summary for this host tab, there 'Problems of Configuration' message "disconnected from esxi_hostname in esx_clustername." "Reason: expired license."

  Is it possible to recover the message above through Perl SDK API? The host is already disconnected from the cluster, not sure if this is possible.

  Yes, you can take a look at the configIssue (http://vijava.sourceforge.net/vSphereAPIDoc/ver5/ReferenceGuide/vim.ManagedEntity.html#configIssue) for the object HostSystem connecting to vCenter, i.e. When this information appears. It contains a table of configuration problems and it is exposed in the API, which means that it can be accessed by using one of our SDKs including the vSphere SDK Perl

• ESXi host profile

  Greetings,

  I'm currently upgrading my 5.1 to 5.5 however ESXi hosts, it is not a rhythm in upgrade more as a new installation since I'm changing some resources on my servers. I create a profile of the host of one of my hosts, but my question is, can I still use the host profile Version 5.1 on version 5.5 hosts?

  Thank you!

  Yes, you can and it works perfectly.  However, if you have any questions you should carefully test this.

• ESXi/ESX host disconnects vcenter Server 60 seconds after the connection

  Hello guys,.

  I recently made some changes to my VMware Lab.

  I'm under vCenter 5.1 with several hosts of ESXi 5.1.  My vCenter ran on one server ESXi 5.1 until I recently migrated there in a window of Windows 8 running VMware Workstation 9.   The vCenter is running normally and I am able to add hosts in stock, but they disconnect after approximately 60 to 90 seconds.  I believe that this issue is that the heart beats that are sent by the host do not reach the vCenter (port 902), I think that it is similar to the issue discussed in the following KB:http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1029919

  Here are my questions:

  1. the article describes download wireshark and run scripts.  Is there an easier away from do?  I'm literally just checking this single port of the ESXi host, there is no equivalent for telnet from an ESXi host?

  2 VMware Workstation 9 block ports or run its own firewall any?  Since this vCenter worked perfectly when running on the host ESXi 5.1 we know this isn't a firewall on the virtual computer problem, I have also checked the Windows 8 machine running VMware workstation and have verified that the windows firewall is disabled.  Windows firewall is not the issue. 

  Thank you

  Duncan.

  Just a quick question. A fact change of IP address of the server vCenter with migration of VMware Workstation? Maybe http://kb.vmware.com/kb/1008030 is related to the question!

• ESXi host running 6 VCSA disconnected from the vCenter

  Hi guys,.

  I have a weird problem with my vCenter build 6. Single cluster of ESXi hosts. Running VCSA 6.0 and 6.0 ESXI. Making a storage of the vCenter vMotion initially got stuck at 77% and the ESXi host running the disconnected from vCenter vCenter. But I can connect directly to the ESXi host with vsphere client and see the vCenter VM works perfectly well. If I try to manually connect host ESXi and vCenter, I get the error "Failed to contact the host specified") both are in the same subnet and VLAN. I can migrate to other virtual machines without problem. I even restarted the host and yet I am not able to connect to vCenter. The host connects to vCenter if I reboot vCenter, but after a few minutes, disconnects again (even if no task does run on this topic.) I have no HA or DRS enabled at this point that I build this new environment and only presented a single LUN as a store of test data to the cluster.

  Any ideas?

  OK, I think I fixed that or have at least a work around. So the underlying question was hiding ID mode/CPU EVC. I'm under the cluster to a level of EVC to reduce until I have migrate workloads from old environment and I think that this created a problem for the unit vCenter. To resolve this problem, I turned off the unit, directly connected to the ESXi host that had the camera running, edited the virtual machine and reset the masking of CPUID. Also, I've hidden the flag NX/XD of the guest. It's temporary (I hope) as once I increase the EVC to the Haswell, I will expose the NX/XD comments and test. For the moment, it is of the workaround I did. It may be of some use to someone.
