ESX host does not not by vCenter

I have a host who has been upgraded to ESX 3.5, a few weeks ago, and it has worked perfectly since then.  All of a sudden vCenter reports that it does not.  I can manually reconnect it to vCenter, but after a few minutes it says that it does not again.  I tried removing vcenter and addition of new but not luck.  Should I bounce the host?

Thank you.

It can be the management agents, try to restart their

the type of service console:

service vmware-vpxa restart

  • ESX host does not not in vcenter

    Nice day

    I have two ESX 4 hosts in a cluster configuration, each running several virtual machines.  Yesterday afternoon, something happened to one of the hosts and now he is in a State of "not responding" in vcenter, and I can not ping to the host or the ping from the console of the host.  Fortunately the other host took over the failed host VMs for now.  The physical box that the failed host runs on seems to be fine, in addition to the switch between the two hosts.  From the ESX console on the failed host, the network configuration is correct, all network cards are up, so I don't know what I should check then.  Any ideas as to where the problem may be?

    Thank you very much!

    If there is no virtual machines running on this host, you should try a reboot.  pass may have crashed.

  • This host does not support VT *.

    I get the message: "this virtual computer is configured for.

    64-bit operating systems. However, 64-bit operation is not

    possible.  This host does not support VT continue with 64-bit support"?

    If I don't answer him then continues to try to start the virtual machine but cancel then with "the task was canceled by a user" even if I don't cancel anything. If Yes, well, after validation, and attempt to start the ISO XP it says "this processor is not compatible with x 64 mode. Please install a X 86 32-bit operating system. »

    That's what I get every time I turn on a virtual machine where I'm trying to start a 64-bit XP ISO file so that I can install XP 64 bit on it.

    I am running 4.1 on a 64-bit VM ESX (Redhat Linux 5 64-bit) of VMWare Workstation v7.  I tried Windows XP 64-bit and other flavors of

    Linux 64-bit but same problem with all of them.

    My physical pc consists of: CPU Q6600 (which supports VT).  The mobo is P5E - VM HDMI and VanderPool (VT) with XD bit set is enabled in the BIOS.  It is running

    to 3.60 GHz.

    So I can't install any 64 bit OS because it tells me that my pc ESX 4.1 VM does not support VT... I started in its virtual bios but there is no parameter VT it.  Yet, when I boot ESX with the preferred Mode of CPU Intel VT-x/EPT or AMD-V/IVR value I get a message bit on the right down saying: "this host does not support the EFA. For material aid to virtualization with MMU software. "So I don't know that he sees VT during startup of ESX, only virtual computers created in ESX do not seem to see it.

    I have already added the following in my vm ESX 4.1 .vmx file:

    guestOS = "vmkernel".

    monitor_control.vt32 = 'true '.

    monitor_control.restrict_backdoor = 'true '.

    I tried also to add the above in vmx file XP 64 bit VM as well.  Any ideas on how I can install a 64 bit OS in a virtualized 4.1 ESX? Or it is not possible?

  • Cannot migrate VM between 5.5 ESXi versions: the version of the product to the destination host does not support one or several CPU features

    We receive an error message that I am trying to make sense. I understand very well the notion of compatibility, CPU, CPUID, masking and so on, after working on a competitor hypervisor. However, this error seems wrong (or needs better wording) based on my understanding:

    Here is the message:

    ----

    A general error occurred: the version of the product to the destination host does not support one or several features of the CPU currently use by the virtual machine.

    Characteristics of CPUID level 0 x 1 'ecx' register are indicated with a '1' bit: x00x:xxx0:xx0x:x 000: x 0 11xx:00: 00xx:11xx

    ----


    This happened during the migration between two hosts ESXi with the same physical processors - in this case, a Westmere X 5650.


    The source host is on ESXi build 2068190 (5.5). The destination host is on ESXi build 1474528.


    The bits it seems to complain are:


    DTES64

    Monitor/MWait

    Cx16

    PDCM

    The punch line seems to be: "the product version of the destination host. However, I have trouble believing that support for these features have been added to ESXi between the two versions. If it were, VMware has been certainly silent about.

    For what it's worth, explicitly set us the CPUID masks in our virtual machines (no, CVS is not an option for us at this time.) This is the mask:

    CPUID.1.EAX = "00000000000000100000011001010001".

    CPUID.1.ECX = "00000010100110001110001000111111".

    CPUID.1.EDX = "10001111111010111111101111111111".

    CPUID.80000001.ECX = "00000000000000000000000000000001.

    CPUID.80000001.EDX = "00101000000100000000100000000000".

    cpuid.d.EAX = "00000000000000000000000000000000".

    cpuid.d.ECX = "00000000000000000000000000000000".

    cpuid.d.EDX = "00000000000000000000000000000000".

    Note that the bits of the message complains (2, 3, 14, 15) * are * in fact forced to '1' in our mask of cpuid.1.ecx. That means (if I understand correctly), ESXi does not have the virtual machine unless the host processor supports the feature. And in our case, the virtual machine will start with happiness on nodes, with both versions. It will be not simply migrate between them.

    So, long story short, is this a bug of ESXi? The error message is misleading? I understand something?

    Thank you


    Matt

    To use the masks feature VM in this way, you must replace all the 1 to your masks with-'s:

    CPUID.1.EAX = "00000000000000-000000 - 00-0 - 000-

    CPUID.1.ECX = "000000-0-00--000---000-000---".

    CPUID.1.EDX = '-000 - 0-0 - 0-

    CPUID.80000001.ECX = "0000000000000000000000000000000 -"

    CPUID.80000001.EDX = "00-0-000000-00000000-00000000000.

    cpuid.d.EAX = "00000000000000000000000000000000".

    cpuid.d.ECX = "00000000000000000000000000000000".

    cpuid.d.EDX = "00000000000000000000000000000000".

    Zeros erases the features that are not available on your hosts Westmere, and dashes will leave the other one features.  The problem with those masks was forced to you certain features on who would have normally been off.

  • ESX host is not responding

    Hello

    now, I have a problem.

    a customer has 3 blade IBM HS23.

    because in the course of the last 7 months I had 4 times the host esx became offline / insensitive

    all the vm continue to operate therefore continues to operate production

    ESX host do not react on SSH connection or telnet

    I can connect after pressing F2 and F12, but then the host everything crashes

    I can't connect to the vi to the ESX host client either.

    all hosts are installed on the IBM's USB drive

    the only thing to solve it is to off the blades and start again

    also random sound. I had 3 months running good, good running 1 day and 3 weeks running good

    the vpxd.log file displays only the waiting times to communicate with the esx host and then the error offline

    already updated all my firmware (chasis, blades, storage, fiber brocade and IBM switches)

    I started with vsphere 5.5 u1 U1 and ESXI 5.5 IBM. already updates on vsphere 5.5 U2 and 5.5 ESXi vmware u2 (since ibm doesn't have an ESXi custom 5.5 u2)

    im stuck... lil last event is on 16/01/2015 (and ibm will not support since there only subscription for 3 years and no software support contract)

    one last point, I'm under bacup veeam and 7.x replication but don't see a problem there.

    Thanks in advance.

    I found the problem

    I've restarted only iSCSI data store and all ESXi hosts becomes sensitive

    so, after searching for the qnap forum I noticed that they have released an update on 29/01/2015

    test of the firmware now and see what happens

    If this fails, I guess the qnap ts - 469L is not taken in charge more for vsphere 5.5

    Thank you all for the suggestions

  • Host does not support configuring passthrough (DirectPath i/o)

    Hello

    I just installed ESXi 5.0 on a Fujitsu CELSIUS W350. http://support.TS.Fujitsu.com/UKFAQ/ProfessionalPC/Celsius/W3xx/W350.htm

    CPU: Intel Core 2 E6300 http://ark.intel.com/products/27248/Intel-Core2-Duo-Processor-E6300-(2M-Cache-1_86-GHz-1066-MHz-FSB)

    As far as I can see that the "Intel Virtualization Technology" is also enabled in the BIOS, but I still just get the message "Host does not support configuring passthrough" under "Configuration-> advanced settings.

    I would like to have access to certain PCI cards in guest. Any ideas how to make this work? USB transfer works very well...

  • ESXi 4.1 - Dell Poweredge 2850 - tape backup - host does not support configuring passthrough

    I'm trying to get a tape backup to work on my ESXi host, so I can save my win2003 VM.  I get this error under VMDirectPath, 'host does not support configuring passthrough ".  Under Configuration > storage adapters > I don't see my tape drive listed.  Also, I noticed that my SCSI controller card is NOT on the HCL (Adaptec 39160).  See.  This is probably why passthrough doesn't work.

    So, I was thinking of buying this one (Adaptec 39320) because he seems to be on the list.  This will solve my problem or is this server too old for passthrough to work?

    To use VMDirectpath on an Intel Server chipset used must support Intel VT - d (Directed i/o).   I don't think that's the case with the models of 2850, but if it was you would see an option in the BIOS to enable this.  It is a separate option of VT - x, which allows the host run the 64-bit clients.

    Hello

    We are currently testing a new infrastructure and you experience this problem:

    On a ucs when disable us an uplink to the FI server to simulate a network outage, the underlying ESX host are the Vnic connection live and does not switch ot the other connection.

    We have this problem with only a ucs, the other does not create this behavior. Failover takes place normally.

    Stephan,

    If I understand correctly, remove you / disable a port from IOM at the END?  OR the FI switch upstream?

    If the FI to IOM = you have Port enabled in the strategy of chassis Discovery Channel?

    If the FI to the switch upstream: are there any other uplink in the same FI?  Y at - it no static pinning applied?

  • ESX server does not pick up its license

    I had to rebuild one of my servers esx yesterday - but he will not meet then this is the license server license. Is that what I should do to make sure that he can?

    OK

    Take a look under ADMIN > licenses. I'm guessing that you have no license available (because it does not fall the license of the previous installation)

    You will need to remove this vCenter server and then refresh your license server (using the FlexIM license software, vcenter installed on your server)

    Once you can see under ADMIN > Licenses a license available, readd your server and you're away!

  • "Host does not support configuring passthrough"--Dell PE 1950

    I was wondering if anyone can shed some light on how I can be able to configure this server to support a passthrough configuration.

    Basically, what I'm going to implement is a server to allow a single customer to use serial port physical on this server, there is no need for other customers would use the serial port so it can be dedicated to this customer, but currently my Dell Power Edge 1950, who has the last patched ESXi 4.0 running on it displays "host does support not configuring passthrough".

    Any ideas or suggestions would be greatly appreciated.

    Thank you

    This KB article is for ESX (i) 3.5, but you can see that ESX supports the use of a physical serial port in a VM and ESXi don't.   If you wish to stay with ESXi and must support a serial port, you can consider a series to the IP for this device.

  • ESX host will not use VMotion

    Hi all

    I have a question maybe someone can help.

    I installed two new ESX hosts in their own cluster, managed by a single data center environment.

    After the installation and updates, adding them to the Cluster environment and adding new licenses to the license server VC.

    I have one of the two ESX host who won't use VMotion. Everything is allowed as should be. But in the section of the Add On to the Configuration of the license, I see the following:

    VMware DRS Licensed for 2 cpu

    VirtualCenter for ESX Server Licensed agent for 2 cpu

    VMotion will not used

    VMware Consolidated Backup for 2 cpu license

    VMware HA under license for 2 cpu

    Additional details:

    Both servers in the cluster are identical hardware profiles: Intel 3.2Gig Xeon, 2 cavities 4 hearts, no HT.

    32Gig of RAM, (Proliant DL380 G5)

    The two servers connected to the SAN via Fibre Chanel Switch, redundant.

    Concert NIC ((VMNic 0 (Console 1), VMNic 1 (Standby adapter), VMNic 2 (Console 2) (the Virtual Machine Network), (VMkernel), (ports of vSwitch 56 none VLAN not defined) VMNic 3 (Standby adapter)).)

    No errors in the Logs of license, the Console message, etc. Everything seems in good health with no update needed.

    Both servers see the unique data store, created on the same SAN which it connects through the switch channel.

    VMFS 3.31.  Unique data store with several extensions (8 in total, the creation of a size of 15 to storage).

    Any ideas?

    All my other hosts using VMotion, but it does not work and there is no difference in configuration, I know.

    Thank you

    Some of the most common problems that cause problems VMotion - have you enabled for VMotion vmkernel port? VMkernel ports on the same segments of entwork?

    Can you provide the ip addresses for your vmkernel enabled for vmotion -
