Snapshoting a virtual machine (Windows or Linux) before a upgrade VMware Tools as a precaution

Our company has standardized on the use of VMware snapshoting than a level 1 to save uninstall mechanism possible to issues related to the updates / patches.  It works very well for Windows updates on our Windows guests, as well as the updates I YOU on our Linux guests.

My question is if anyone thinks that there is a risk associated with the use of this process to guard against a possible problem that might occur after an upgrade VMware Tools.

The process would be: Patch ESX host, migrate a guest to host newly patched, instant, prompt, install VMware Tools update, restart, test and certify, delete the snapshot.

Since you're snapshoting a system that has an older version of VMware Tools, it's a bad idea to rely on this snapshot in a recovery scenario?  Use the VMware Tools as part of the process of snapshoting a guest?

Thank you all for any advice you may have!

Matt Heldstab

Yes, you can snapshot before the upgrade tools and come back if something don't jive.  To take it even further, you can snapshot before the hardware upgrade of the v7 and return to v4 if it does not work.

Seems like a lot of works well, but it does not offer a good backup method.

  • Recognizing the hardware of a Windows virtual machine hosted on Linux

    Hello

    I would like stable windows in a virtual machine running from linux and run my VI labview and make the acquisition from there.  I tried once using Windows XP 32 - bit virtualized on ubuntu 64-bit, with Virtualbox, but windows setup does not recognize my card PCI-MIO-16-4.  Maybe its because I had not installed the linux drivers... I do not know.  Soon I will start using an FPGA 7853R with the PXI-1036 chassis and would prefer if my Windows installation virutalized could see this material.

    Anyone who crossed through the stages of the use of materials of a virtual Windows installation?  VirtualBox, Xen, Vmware or whatever...

    Thank you

    -Sidney

    Hello

    National Instruments do not support virtual machines, but I'm sure that your PXI will recognize by your system. Max peripheral use ethernet to find devices, so if your network works, you will be able to use it.

  • Converted to a virtual machine (Windows 2003)

    Hi @ all,

    I tried to convert a virtual machine (Windows Server 2003 Standard Edition) since an ESXi 4.0.0 Server for our new Cluster (ESXi 5.1.0). After 2 hours of waiting, the process failed at 1% with ' error: event.» DiskCloneFailedEvent.summary ".

    ESX server and the virtual machine are in the same network.

    Two weeks before I tried the same Conversion, but had to stop due to a colleague, who needs the machine urgently. At the moment the State of conversion was 9% and I think that he would have been success.


    Here are the logs of the converter and I hope, someone can help me with this question:

  • Different drag / drop behavior of the mouse on different users on the same virtual machine Windows 10 Pro accounts

    I just upgraded to 8.1 on Mac OS X 10.11.3 Fusion "El Capitan" on a new iMac 27-inch 5K retina. The guest operating system is a new virtual machine Windows 10 Pro. I have two user accounts on the virtual machine, my local administrator account and another account local standard user. When I am logged into my account, I am able to drag and drop files to and from the guest to the normally Mac OS. As the mouse moves freely between the guest OS and the Mac. However, when I connect using the standard other account, I can't drag - move to and from the guest for the Mac OS. Also once I click into the virtual machine the mouse movement is limited to the virtual machine until I have press the buttons on the Mac to free the movement of the mouse to the Mac. I tried to uninstall and reinstall the vmware tools but the same behavior persists. Any ideas on a solution and why these two users accounts would act differently?

    Just phone with the help of VMware. They solved the problem in uninstalling and reinstalling VMware tools and change the following VMware Fusion preferences-> preferences-> General-> Gaming: to 'Never mouse optimize for games '. It has been set to 'always optimize the mouse for games '.  After that drag & drop, mouse movement works smoothly and perfectly now. Thank you VMware support!

  • Cannot ping virtual machine Windows 7 vm Server 2012 [Server R2 2012]

    Hi all

    I'm not sure that this is a vmware workstation or server 2012 r2 problem, but I would still ask thought.

    I have a 2012 r2 vm server and win 7 vm in a ' host-only: a private network, shared with the host country "network connection.

    I can ping the server vm win7, but cannot ping the ""Server the VM win7 ". "

    But when I point the win7 dns on the server 2012R2 (that has AD and DNS configured) I can join the virtual machine Windows 7 announcement.

    Its totally weird

    Whenever I try to win7 from the ping server, it says "Request Timed Out".

    Does anyone know how can I fix?

    I'm using VMWare Workstation 11

    Thank you

    I found the solution.

    I disabled the JOB BE general relativity.

    and the host where the virtual machine belong was not the right time. No Ntp server has been configured.

    I think that the problem can come from this.

    Hi Requiem88,

    Just to be clear, you press the Option key on the keyboard key then went in the Virtual Machine menu at the top of the screen and choose Force Shut Down who?  Looks like you force quit in the menu Apple have rather choose.  Force quit will put end to VMware Fusion, while the option Force stop menu stop permanently from Windows itself.

    See you soon,.

  • Why do I see virtual machines Windows 7 x 64 in double after the upgrade to Fusion 6.0?

    Join support information.  Would rather have only listed here.  The two seem to shoot to the top of the virtual machine itself.

    According to the information of the single bundle media of entries in the library of the Virtual Machine Windows 7 x 64 is actually a Virtual Machine.  So delete that which is not actually start a Virtual Machine.  (Council: Ctrl-click on the object and select Delete.)

  • IP address on the virtual machine windows endangered endangered after the importation of the data store.

    I'm gaving a problem with the IP on windows vm disappear after having mounted the snapshot to restore. Here's what I do.

    Mount making LUNS to the esx host area

    I have eyebrows outside the data store to find the vm I want to right click and click Import the vmx file.

    Imports of the virtual machine and when I start it up I wonder if I've moved or copied the VM. I have tried both moved and copy but when I connect to the virtual machine is missing all its IP info.

    Any way to avoid the losting vm sound IP info when I import to the host from a LUN outlet?

    Hello

    Installs on the forum of the Virtual Machine and the guest operating system.

    The MAC of a virtual computer is based on the UUID/name of the virtual machine so if you are not using a static MAC (one that recognizes VMware) and it will change the IP address might also change if you are using DHCP. So I suggest to use a static MAC in the VM configuration.

    Another way is to set up the guest operating system in the virtual machine with a static IP address instead of a DHCP function.

    But if you are unable to remove the virtual machine or the copy in the virtual machine, there may be something locking these files would be an another running virtual machine. If you need to find this VM and kill him. In this case, "vmware-cmd - L" and 'vmware-cmd - l' host in question can be useful to find where the 'hidden' VM is running.  Ultimately you can use ' vm-support - x "to find a list of the virtual machines running by how the hypervisor lists. Then use 'vm-support - Z' to suspend the offending virtual machine that should unlock everything.

    Yes, the use of these commands is command line.

    However, before using these commands determine if you can find the place where life VM incriminated.

  • Question about snapshots and virtual machines

    Hi all

    I have a small question about snapshots. I use VMware for about 6 months and I read about snapshots and how they work but still have a question to make sure that I understand how it works and it will work the way I think it works.

    I have a Windows 2003 server, which is a virtual machine. I have an application that uses MSDE database. I want to upgrade the database to MS SQL 2005, but to do this I need to back up the MSDE database, uninstall MSDE, and then install SQL 2005 and move the SQL database. This happens on the same VM.

    What I was thinking if I well Snapshots correctly is to snap turned the virtual machine before doing anything. Then do my upgrade steps and see if everything works. If its all messed up so I should be able to return to my shot and everything should be the way he had. What is the good? One of the main reasons I moved the server VM was because of this upgrade.

    After reading the documentation for the snapshots, it's how I undestood it. Pretty much any change could be reversed with snapshots. I wish just they had put in a few examples in the PDF file. Also it would be the same for all type of grades of the OS? Could I snapshot a Windows 2000 Server, and then "in the upgrade of the square" to Windows 2003? I've cloned a VM to do this but was curious about whether snapshots would be just as easy.

    Thanks for your help.

    Hello.

    That is right.

    Exactly the same thing for the upgrades of the OS.

    Perhaps the most important thing with the snapshots is to keep an eye on them and don't let them sit too long or become too big.  You have described the use cases are very good uses for snapshots.  Just make sure you have a solid plan with a schedule set, so that you can come back or validate changes before the snapshot becomes too large.

    Good luck!

  • VMTools fails to run for the virtual machine Windows 2000

    My first post.

    Just installed VMWare Workstation 8.0 on a Windows 7 64 bit computer and I'm trying to create a virtual machine to Windows 2000 Professional from a CD of Installation. I'm trying to resurrect an old machine from the grave of cyber.

    I created a disk image ISO of the installation CD Windows 2000 Pro original and then used the new computer Virtual Assistant to create a new virtual machine from it. Everything was fine, the new virtual machine started using the video driver by default since the installation media. Therefore I could not make any changes to the screen. VM Workstation suggested I have install VMTools.

    But when I installed VMTools, installation fails just before she completed displays a dialog box stating "Setup failed to upgrade Windows Installer.

    So I have reproduced the same process on a copy of VMWorkstaion 6.5.2 running on a Windows XP-based computer by using a copy of the same ISO image. I installed VMTools and completed the installation successfully. Then I cloned the machine and copied to the first machine. The new virtual machine booted up and I was able to make changes to the screen. However, VMWorkstation 8.0 informed the VMTools was outdated and run it again. When I did, it has exactly the same way as it did before.

    Although the new virtual machine created the 6.5.2 VMWorkstation works better, I prefer to have a recent version of VMTools install correctly on this virtual machine.

    Does anyone have any ideas or solutions?

    I think Win2000 needs to be patched to Service Pack 4 to the latest version of VMware and the VMware tools.

  • VCB backup snapshot or virtual machine?

    Hello

    Workflow of VCB, I read these procedures frequently and I'm confused by what backup software is stored:

    ".....  Put the virtual machine snapshot mode and take a snapshot.

    .. .Mount snapshot of the VM for the proxy backup (to win)

    .. software backup .the performs a regular backup of the snapshot of the virtual machine moving data from backup media... »

    So I wonder what backup software is saved: any virtual machine or virtual machine snapshot? and why?

    And for linux, it will export (copy) the snapshot of the machine the VCB proxy virtual of the SAN. If a single snapshot is stored to the proxy of VCB mount point, why VCB proxy must have enough space to contain the largest virtual machine?

    Can someone give me some clarification?

    LAN

    To clearify:

    In the world of VMware ESX, a snapshot is the same as the 'entire virtual machine' as you say. It's just the disks 'frozen' in a State of know. VCB can then move up and back up this disk (or copy it to the VCB proxy) while the virtual machine is placing the changed data in the temporary file. Some people refer to this temporary file that the file 'snapshot', while the other, see you in the frozen file as the 'snapshot' file, and creates confusion for users/students. A 'snapshot' is simply the functionality described above.

    When the backup action is finalized, VCB tells vCenter to "remove the snapshot" which actually means that the data in the temporary file are merged with the 'frozen' disk that is then back 'defrosted' and put into live operation.

  • VCenter can create virtual machines Windows 7 x 64?

    After creating a new virtual machine and then loading an ISO file on the cd to start it appears as if the operating system loads correctly until you get to the point of restart the machine. Im hoping just to confirm that vCenter Server takes in charge the creation of Win7 machines currently.

    I was able to do a P2V of a Win7 x 86 box conversion but it is the first attempt, I did build a x 64 VM from scratch in the new agent of vSphere. Do you mean that the ESX hosts must be upgraded before it works?

    Guests must be upgraded, to ESX 4.0 U1 until you have a supported configuration.  32-bit or 64-bit Windows 7 to work on ESX 3.5 hosts is possible, you will just not supported with it.  It really comes down to whether or not you need a client supported OS.

  • Virtual machines, run extremely slow when the console is consulted 2 virtual machines Windows Server 2008 64-bit, Windows Server 2003 32-bit, 2 VMWare for virtual machine

    I'm in a difficult situtaition here.  I am the daily contact with a new client.  My linux guy, who is also my boss who is very busy, asked me to do some research trying to find answers for what's not on this server. We have a dual Quad Core 2.5 Ghz Lenovo server with 10 GB of ram.  2 500 GB hard drives are Raid 1.  We run Virtual Server VMWare 2 on a Debian with Gnome installation as a user interface for the side of things Linux.  Grub is the boot loader. There are two virtual machines running on the server.  The one machine that serves as a domain controller is a Windows SBS 2008 Server 64 bit, and the secondary machine has no responsibility domain.  The second machine is a Windows Server 2003 32-bit.  the 10 GB of ram 6 GB is allocated to the SBS server and 4 GB to the 2003 server.

    The problem I am running into is that everything is so slow, especially if I connect remotely to do any sort of administration on the network.  Some examples of issues I've noticed is that as soon as I log on the server via Remote Desktop SBS console management Windows Server spike to 80-95% CPU usage and it will not stop unless I close the management console.  Another instance is that if I open Backup Exec 12.5 on the SBS server it will kill the speed of the processor as well.  Long story short, there are a lot of machine to do what we need to do, but something is not configured right and non of us know what it is.  Another point to note is that the server has been in production for about 3 weeks, and the server seemed to have locked up just twice.  My professional guess is that over time, some chose thing is eating causing the crash of the memory.

    Sorry I do not have much technical insight on this topic, but this is the best I have to offer.  Any questions you all have, I'll ask my people and see if I can answer, but I could really use your help here.

    Thank you in advance,

    Heath

    2 things:

    1 you really need hard drives more than 2 in a RAID 1 for proper performance under load. More disks the better. Although I don't think that's what your problem is, he'll probably be the problem Next you will do.

    2. I don't know exactly where the configuration file is on your box of Debian for VMware Server, but you should consider adding the following options in the configuration file (on windows, it's the vmware 'config.ini'):

    prefvmx.minVmMemPct = "100".

    MemTrimRate = 0

    sched.mem.pshare.Enable = "FALSE".

    mainMem.useNamedFile = "FALSE".

    If you do some research, you can read about what these options (the largest is the memory page sharing - it should only be left on if you have a bunch of similar virtual machines running on the same box, that you don't have.) I honestly know why this is on by default, he kills the CPU when virtual machines are running different operating systems). These are the options that I now use standard in VMware Server deployments, with huge performance increases after you have added the. Just give a try.

    Edit: Also make sure that you have installed in your virtual machines VMware tools.

  • PCI express peripheral on the virtual machine Windows on Macintosh?

    Wow, that's a long title...

    I was wondering if anyone has tried to use a hardware DAQ PCI - e installed in a (recent) Mac Pro (which has PCI express ports), which runs under Windows in Parallels or VMWare Fusion.

    I have customers who hate Windows, love their Macs, cannot use NOR-DAQmx Base and could barely tolerate Windows running as a virtual machine on their Macintosh.

    Hi John,.

    Unfortunately, a Windows virtual machine does emule not entirely software low level required to run on a Macintosh DAQmx.

    That your customers can do, however, is running Bootcamp to install Windows on their computer, and then they will be able to use DAQmx.
