Nested ESXi 5.5 crashes with a misconfiguration EPT

Hello

I have an ESXi 5.5 installed on a physical machine (CPU: Intel i7 - 4770 s, 32 GB of RAM), where I have 2 nested ESXi servers. Each of them (physical + nested) execute the last ESXi 5.5 1881737 and time at time, the accidents of the ESXi nested with [msg.log.error.unrecoverable] fatal error VMware ESX: (vcpu-0) 2014-06 - 21 T 20: 03:51.580Z | vCPU-0 | I120 + vcpu-bad configuration 3:EPT:

The nested 2 ESXi virtualization CPU/MMU was set to automatic, then on the last option (use Intel VT - x and Intel EPT for MMU virtualization). Same situation... Version 9 hardware

I have not tried the other 2 options again, may one of them be the answer to get rid of this?

I know it is not taken in charge, but maybe someone has an idea on how to solve this problem... Found this KB VMware: virtual machines stop abruptly with a similar error to: MONITOR PANIC: vcpu - bad 0:EPT configuration... , but this is not applicable .

I am also attaching the vmware.log, zdump and vmmcores...

Thank you for your time.

Please try to add the following configuration option to/etc/vmware/config on the physical host:

monitor_control.disable_gphys_abit = TRUE

  • Nested ESXi 5.5 lab for the SRM demo with iSCSI

    Hi all

    I was wondering if it is possible to install ESXi in ESXi 5.5 5.5 make recovery of the Server Tier - 1 Microsoft with Site Recovery manager?

    So level 1 server applications are: Exchange Server, SQL Server, SharePoint Server and AD DC servers with 5 x test Win 7 desktop.

    The external data store to the VMFS will take place by iSCSI NAS connected to the physical server.

    Any suggestion and input would be greatly appreciated.

    Thank you

    One thing you'll want to do is to make sure that use you VSphere switches distributed on your cluster nested to ESXi hosts so that you can use the network i/o control (NIOC). For me, I put iSCSI to high priority traffic and everything to normal priority.

    With the help of the NIOC will allow your cluster nested in order to operate more fluidly than without it.

    My SRM 5.x laboratory is fully nested - probably not supported in a production environment where supported VMware should however.

    Here's a blog post of Ather Beg on its results by using the nested NIOC and ESXi hosts - it is the reduction of the spikes that Ather blog article shows that made work nested ESXi hosts networks so much better:

  • Nested ESXi 5.5 laboratory

    I was pulling my hair out with this now. Trying to nest ESXi 5.5 within ESXi 5.1 on a HP DL380 G5, but I get the error: hardware virtualization is not enabled in the BIOS, when I try to install 5.5

    I already did:

    -Edited the file/etc/vmware/config for vhv.allow = 'true '.

    -Updated the VM to support v9

    -Changed the OS to ESXi 5.x (experimental)

    -Tried to edit the virtual machine's .vmx file, putting in vmkernel5 instead of 64 others in the field of guestOS

    None of this worked, always get the message about hardware virtualization is not enabled in the BIOS of the virtual machine. Anyone nestled ESXi 5.5 yet? If Yes, how did you you do and are there are instructions there. I tried following some blogs out there on the Internet, but nothing has worked.

    In addition, the BIOS of the physical machine is up to this day and ESXi 5.0 (nested or otherwise) ran flawlessly on the G5.

    Help is appreciated. TIA!

    If it were possible to use virtualized virtualization assisted by material on systems without EPT (Intel) or IVR (AMD) under ESX 5.0, this configuration was not taken in charge. EPT or IVR is now required for virtualization to support virtualized under ESXi 5.1 (and other VMware products that virtualized hardware-assisted virtualization support).

    Unfortunately, your CPU does not support the EFA.

  • 5.1 nested ESXi

    Hello world

    I am configuring a nested ESXi 5.1 training lab on my production 5.1 esxi environment.

    The problem I have is that, once the installation disc starts, it does not detect the vmdk file in local storage.

    I created the guest computer using the web client so that it is hardware version 9, added the vhv.allow = true for the comments and also permit EPT Intel VT - x on the client.

    I thought that maybe it's because my local data store where I was hosting for the nested esx vmdk file was VMFS version 3 so I've updated that and it did not solve.

    Am I missing a step somewhere? Any help would be appreciated.

    Karl

    Maybe that's the problem with the controller. try and change the bus to the VMDK controller?

  • Nested ESXi 5.0 Workstation 9 Networking question

    I use standalone desktop with 16 GB memory with windows 7 and installed workstation 9.  I created my configuration of base, DC, ESXi-host1, host2 ESXI, ESXI-host3 and host4 ESXI.  I also installed vcenter as a virtual machine within the workstation and I can access all the hosts and vm (DC, vcenter) by name and IP.  Also DC and vcenter, I can connect to internet using vnet0 (workstation).  My management is vnet3 and my storage is vnet4.  I created a new virtual machine called vcenter in ESXi-host1.  I then installed vcenter server and vsphere client.  Everything works well.  I went to install web client and adobe flash player, to internet access.  For switch 0 I vmnic0 active and vmnic1 in mode standby.  The ports VM group vm network which has vcenter vm and vmkernel port with network management.  I went into properties and accepting promiscuous mode network times vswitch and vm.  I can not even access the internet.  This is where I don't know what to do then.  Suggestions?  If you are in need of more data, let me know and I'll give it to you.

    Given that I have not found it necessary to connect to the external network, I have not deployed router. To test, I have now deployed a virtual router to connect external network and my VM on nested ESXi can connect to the external network and was able to ping the DC VC etc...

    (1) deploy a Virtual Router download by http://freesco.sourceforge.net/

    (2) connect two network to the router as a display in the snap-in and configure the router

    (3) configure the default gateway of all VM (that is to say DC VC and ESXi host) to use the IP of the router.

    (4) Finally the VM on nested ESXi can connect external network and ping to other virtual machines too.

  • Unable to start x 64 VMs on nested ESXi host

    Hi gurus,

    I would ask your expertise on the question with my ESXi nested 5.1 checking. I managed to install the nested ESXi host, but I can't start a x 64 VMs. I continue to ask me what follows:

    x64.PNG
    Intel Core i7-3770 CPU @ 3.40 GHz
    DH77EB
    EBH7710H.86A.0100.2013.0312.1351
    Virtualization / VT - x is already enabled in the BIOS.
    Turn off the Bit is also activated.
    verified the host physical and NestedHVSupported set to TRUE
    added vhv.enable = "true" on the physics of the host \etc\vmware\config
    created nested ESXi VM
    original operating system is any other 64 bit
    Once the virtual machine is created, I changed the OS to VMware ESXi 5.x (experimental)
    NX/XD flag is already set to expose
    added - H - mask CPU; ECX
    Adds the following on the nested ESXi vmx file:
    Monitor.virtual_mmu = "hardware".
    Monitor.virtual_exec = "hardware".
    VHV. Enable = "true".
    monitor_control.restrict_backdoor = 'true '.
    Thanks in advance!

    According to the journal of the ESXi VM file, its configuration (.vmx) file does not contain the vhv.enable = "true" entry. Only the configuration file contains, that was how it should be done in ESXi 5.0, but not in ESXi 5.1.

    Try to add the entry to the ESXi VM and make sure you reload the configuration (see http://kb.vmware.com/kb/1026043) before turn VM ESXi.

  • VCenter Server Appliance fails without VT in nested ESXi 5.1 support

    I am trying to run vCenter Server Appliance in a nested ESXi 5.1 64-bit environment.

    At the start of the vCenter Server Appliance, it fails with:

    This virtual machine is configured for 64-bit operating systems. However, the 64-bit mode is not possible.

    Thanks again nested VM experts!

    ESXi does not support on your processor hardware-assisted virtualization.  If your processor is AMD - V, there was a design flaw with the first generation of AMD - V parts that we have chosen to not to bypass.  You will not be able to run virtual machines nested on this material.

    ESXi 5.0 supports AMD - V only on later processors and family 10H.

No one knows what to do to keep my computer running efficiently? In addition, someone at - it a solution to the issue with Notes crashing?

    Try each of them in order. A test to see if the computer works properly:

    1. Reset the PRAM
    2. Reset the controller (SMC) system management
    3. Start the computer in Safe Mode, and then restart normally. It's slower than a standard home.
    4. Repair the disk by booting to the HD recovery immediately after that the chime press the command and R keys until the Utility Menu appears. Choose disk utility and click on the continue button. Select the withdrawal (usually Macintosh HD) volume entry in the list to one side.  Click first aid button in the toolbar.

  • PC crashes with DBO when downloading a file using Firefox to my iPad

    PC crashes with DBO when downloading a large file via WiFi to my iPad and using AVPlayerHD player on the iPad. There is no report of error in Firefox, just the crash dump Windows 7 due to the accident. Only the combination of Firefox on PC and player AVPlayerHD on iPad causes this crash. Any other combination of PC and iPad works.
    Examples:
    Firefox on PC and iFile on iPad works well.
    Google Chrome on PC works with all programs on iPad.
    Firefoc on PC and player AVPlayerHD on iPad crashes.

    So you get a Blue Screen of Death on your Windows Machine? You have the exact error codes that appear when you get this blue screen?

    Blue screens mean that you have a problem with a driver, hardware or virus on your PC, not with Firefox. I try to launch a program of analysis such as http://www.resplendence.com/whocrashedand see if she can tell you what triggered the accident. Also, make sure that all your drivers are up to date on your computer (especially the graphics driver: update your drivers graphics to use hardware acceleration and WebGL) and check the virus (Troubleshooting Firefox problems caused by malware).

    After that, if you still get the blue screen and crashed does not help, I would say to try to test your RAM with a utility such as http://www.memtest.org/

  • Satellite Pro M10 freeze and crash with some programs

    Hello

    I have a M10 Pro Satellite...
    A few weeks ago it's freeze and crash with some programs like wmpayer, messenger... I delivered to the authorized agent and they had not detected any problems.
    Already I have formatted several times, but the problem persists.

    Any idea what this may be?

    Thank you

    Hello

    For me it looks like you might have a motherboard problem. Formatting removes the chance that it is a software problem. Try taking 1 stick of RAM and test with it. If she continues to crash, remove that stick and try it. If she does it with the two RAM then those who are ok. HARD drive is not the culprit, so now he could either be processor or MB. Find a program to measure the heat from the laptop and run some heavy programs do overheat. If the temperature goes up and then it crashes, it could just be overheating. If it continues without overheating you either have a CPU or MB problem. I hope this helps.

    For general advice, see troubleshooting problems with iTunes for Windows updates.

    Error sharing a trend similar to that in the third box, so a similar approach should work. Looking for CoreFoundation.dll in:

    • C:\Program Files\Fichiers Files\Apple\Apple Application Support or
    • C:\Program Files (x 86) \Common Files\Apple\Apple Application Support

    Delete if found, then repair Apple Application Support.

    The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach. Review the other boxes and the list of documents to support more far down page in case one of them applies.
