iptables, limit of carrots, upload the data... store in esxi 4.1

I would like to run a machine virtual single windows 2008 hypervisor free vsphere 4.1.

The sole purpose is to use iptables to filter all traffic to the esxi host and the windows prompt. I haven't needed the features of virtualization fancy, I just need to protect a windows with a little expensive but powerful Firewall Setup, and although virtualization might do the trick. I already tried with xitrix xenserver and found several problems... It is now time to vmware

The windows prompt will run game servers, so it is important that no jitter and (almost) no delay is introduced into the network. I also prefer to avoid validation CPU and RAM resources for a second virtual machine if it was not strictly necessary.

That's why I prefer to do all filtering with iptables on the level of the host layer and not in a linux host. In my view, it is possible to enable SSH on the host computer and play with iptables, I guess on the ENTRY (to protect the host) and FORWARD (to protect the guests) channels. Well, I guess it's safe enough to do so, provided that no network no associated settings will be affected in vsphere after that?

I don't know which are the limits of the free vsphere hypervisor edition. On a Xeon W3520 (4 cores + 4 hyper threading), I'll be able to use all 8 cores in the guest windows 2008 standard system (affecting multiple cores per processor as explained here, to avoid to reach the 4 plugs windows limited)?

What are my options to download the file .iso windows image in the data store? Last time I looked the vsphere client, I could upload it only on my local hard drive and wget was not available in SSH (command not found). My crappy DSL download speed of 384 Kbps, this is not a viable option. The box is headless and located in a remote data center. I have esxi installed via the automated installer netboot provided by the farm, which formats the two hard drives.

I guess I could get an answer to most of these questions by just trying, but unfortunately, the checkbox I able to run esxi is this one, and it's a box of production... so before I do that I need to document myself to be able to work quickly and with as few surprises as possible.

Thank you

Hello crossed.

Welcome to the forums.

There are no firewall in ESXi. See here: http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=1026845 .

There's no other way than to use a virtual machine to filter access to the virtual machines and the management network.

Run a virtual machine with 8 vCPUs, to Enterprise Plus license. And it is not recommended to give all the processor cores to a virtual machine, that host a. vSphere need CPU resources to run the client. If your guest consumes all CPU resources, your host will not be able to handle comments properly.

To load an Iso file on a data store, you can also use WinSCP or FastSCP.

Good luck.

Franck

    Abrams,

    That's all I can help you.  These instructions are based on the Perc 5 / i controller, which I think you have on our system.  You have not specified the server so I just assumed that this is so.

    1. unscrew the hot spare that you just made.  Follow this link from Dell.
    http://support.Dell.com/support/eDOCS/storage/RAID/PERC5/en/UG/HTML/chapterh.htm#wp1061343

    2 follow the link for the installation of virtual disks - http://support.dell.com/support/edocs/storage/RAID/PERC5/en/UG/HTML/chapterh.htm#wp1069357

    This link has three steps to void, skip the step on "spare parts of designate hot."
    a. create the virtual disks and select virtual disk options.   -Online steps to create another disk group and add the new disk to the disk group.
    (b) designate the drives hot spares (optional). =>, YOU CAN SKIP THIS STEP
    c. initialize virtual disks. -online must do.  just do not initialize the incorrect disk.

    After the step #2 c, you should be able to access the drive in ESXi or command-line (list of nmp esxcli devices).

    And no, you cannot add this manaully until do you step #2 above which is to define the disk group, creating virtual disks and initialize the virtual disk.

    Good luck.

  • Cannot remove the data store in esxi 3.5 - can help you

    OK - I have a problem. I messed up and now I'm stuck.

    I was "apparently" in the middle of a converter working, and I deleted the comments of esxi3.5, while the converter still worked.

    I selected the rafale and made a removal of the disc that worked, however the structure of associated file (windows 2000 Server) for this guest has not been deleted, so I chose my data store (datastore1) and - do you have a store of navigation data and when I try to delete the folder associated with the guest, I deleted I get the following error :

    "General failure caused by file" (with a "/" on the next line) and all I can do at this point is to click OK box to acknowledge the error and I can't delete the folder. I can't rename it either.

    I don't know how to get rid of it. I tried to create a new client with the same name as the folder and delete the comments again, but that does not work either.

    I'm really stuck - I'm afraid to go into maintenance mode because I have no idea what I'm going to be confronted here since I never used the maintenance mode.

    any help or ideas would be really appreciated.

    You can try to do a refresh of the data store. The folder structure is not re read very often. In the data store Navigator, click the folder root on the left side and click on the Refresh button.

    Hi all

    We use the host ESXi 3.5 on DELL PE 2850 with RAID 5 local storage.  Today, I ran utility update for the host VMware and firmware updated BIOS and RAID on the host computer before a restart of the system.  After the reboot, the system correctly loads the operating system and when I check for storage, the data (with critical VM) store is missing.  Can not see that again.

    Please help me to recover my data with the virtual machines in her store.

    ESXi is installed on the same Partition RAID 5, which is located in the VMFS data store? for example. do you know that the partition is still intact?

    According to what the RAID firmware upgrade has done, it is possible that you may need to set the LVM. EnableResignature option 1 if the score ended with a new UUID.

  • VMX file larger than the maximum size supported by the data store

    Hi all

    I seem to be getting a strange error trying to a virtual machine that is located on a snapshot VMFS5, to the data store format.

    The virtual machine (VMDK and VMX file) is installed on a thin provisioned 2 TB datastore which has the value VMFS5 formatting.  It is a data store new with no other VM on it.  I had problems in the past with the datastore block sizes (1 MB, 2 MB, 4 MB, 8 MB on VMFS3), however, I thought that VMFS5 got rid of the question, since it's all blocks of 1 MB and all files in the virtual computer are on the same data store.

    The error I get indicates that the VMX file is too large for the data store (used Im saying "unspecified file), however, if I do the independent 2 TB disk snapshots through the fine.  The virtual machine has two virtual disks, a 50 VMDK of GB and a thin 2 TB VMDK (200 GB used).  I tried fast vMotioning the VMDK and VMX to other data formatted VMFS5 stores and still get the same error.

    I'd appreciate any help and ideas.

    Thank you

    Travis

    Although the block size limit is party, maximum 2 TB file size less 512octets still exists. Since a Flash disk can grow waist put in service the basic disk more overhead for the metadata, the maximum size of virtual disk - to be able to create snapshots - is 2032 GB.

    I see the barebone specification and seem that your controller is a 'soft' RAID

    Take a look at the configuration of the SATA controller.

    When your drive will be recognized as/dev/sdXX, then you can create your data store.

  • Machine virtual IOPS / s report, how to display the name of the data store?

    Hi guys

    I am new to the Foglight community, this is a great tool, and I learn a lot.

    Currently I am trying to create a simple table that will show me metric of my VMware environment: Virtual Machine name, Datastore IOPS and data store.

    However I can't find how to include data store name in the table, because it is not a measure of the Virtual Machine. I think I need to expand the scope of my table to include VMware Datastore, but I don't know how to do this.

    -Mark

    Check the options available it seems that it can be done with WCF (the frame behind the Foglight dashboards).  We recommend generally customers who plan to build views WCF take adequate training or our PSO people engaged in it.

    In any case I can help show a quick example of how it's done.

    Please try this on a local/test server.

    Go to Configuration > definition >

    Make sure that you are in my definition, and click the icon to add a view. then choose from the tables and trees - oriented line table

    Give a name to the view, go public and make a portlet/reportlet and apply

    Switch to the configuration tab and click the change for the lines and choose a query

    Under query, expand the VMware and scroll down

    Until you can select the query for virtual machines

    And press the set button.

    Your view should look like this

    Now you must select the columns.

    Each column has a value you can edit and there is a button + to add additional columns.

    Lets start with the name of the virtual machine - click on the button to change to your default column and choose the context.

    Click on the drop down menu to enter key and choose the current line (virtual vmware machine)

    Click on the drop down menu to access path and scroll down until you can select the name and then click on set.

    You have created a table that lists the names of all virtual machines.

    You can click on save. and then click test, choose a time and click the result. A new window will open a show the list you of virtual machines.
    From here you can continue to add additional columns, each time choosing the key entry in the current line and the path to the metric/string to display.

    For example, the name of the data store.
    I change the module

    Click the configuration tab and click the icon to add a column

    For the column value, that I chose defined context once again, the key input is the current row and for the path, I expand the node for the data store

    And scroll until I see the Proprietename

    If you save and test you will see the result

    Keep adding columns and the data you want, notice that you have arrows that allow you to control the order of the columns.

    Note that you can click Show advanced configuration properties

    This will give you the opportunity to see the properties of the extra table, such as header - giving you the opportunity to give a more meaningful name (name of the data store, the name of the virtual machine, etc.) to the column header.

    You can now go you drag and drop the table edge/report and under my eyes, you will see your new view

    Drop it in the main view

    I hope this has given you the starting point to build this table.

    As I said, I strongly recommend going through our WCF training if you plan build more custom views or hire software Dell PSO Organisation to help build you views that correspond to your need.

    Best regards

    I have a VM that signals a connection to the local data store on its host, and therefore can't do vMotion elsewhere.  The virtual machine has two virtual drives, which are both on a SAN storage.  The virtual machine has been previously connected to an ISO on the local data store, but it has since been replaced by client device.  He always insists that he's using something on this data store, however.  I've looked through the vmx file and don't see any reference to it.  I also tried to remove the data store, but he claims that the file system is in use.  The hosts have been recently updated to esxi 6.0 U2, and it's the only VM that now seems this behavior.  Any suggestions on what could be the cause?  It is a server important enough in this environment, and be locked into a single host makes me a little anxious.

    Turns out it was because of an old cliché.  If you get an ISO from a data store and take a snapshot, the virtual machine will keep a link to that store of data even after changing the client machine.  As soon as you delete the snapshot, this relationship goes, and access to this database is therefore more a review when searching valid hosts.
