Find Snapshots in Vmware environment

• Take snapshots of VMware preferred Cisco Infrastructure

  Hello community,

  We have several Cisco first 2.x and 3.x facilities in the area. All are virtual machines on ESX servers. Before the operations of the crtitcal system (as updates, etc.) I used to take a snapshot of VMware. So far, I never had to use a snapshot to revert to the previous state of the system, but I was always sure to have a snapshot, just in case something goes wrong.

  Now a customer recently asked me if the database would not get damaged if I just take a snapshot of the currently running system. I was courious and tried to look this up, but could not find clear instructions for this. The question that bothers me is: what should I stop NCS before taking a shot or not? Does anyone know what Cisco recommends (kind of best practices) for making snaphsot of VMware?

  Best regards

  Benjamin

  Hi Benjamin,

  Please see the release below notes... Snapshots are supported but recommended to take during their stop. I made quite a few installations and upgrades, and always take snapshots while the virtual machine is turned off, is faster and safer on big high transaction VMs.

  First 3.

• Break a Microsoft cluster and attends independent P2V in a VMware environment

  I searched and searched for the best possible, answering this question and can not find specific answers!

  I have a file server Windows Server 2003 in a 2 node cluster (active/passive) with resources on a San, and what I want to do is:

  1 remove the cluster and have all the resources on a single machine.

  2. rename the machine with the resources on the virtual server name (cluster name)

  3 do a P2V to the file server in my cluster vmware environment

  I have no problem with the steps 2 and 3, but remove the cluster and will strictly autonomous is my Goliath. What I have read, I need to move all resources to one node, then stop the cluster service on the other node, then delete the node. From there I don't know what to do. Help, please! I want to achieve in the coming weeks.

  Check this Microsoft kb article.

  Another option could be to create a new file server in a virtual machine and then attach the storage where the actions as a RDM.

  Options are always good.

  Good luck!

• Snapshots of VMware

  Hello

  I would like to know if it would be a good procedure to when you do upgrades or install a patch do a 'snapshot' with vmware. I have my daily backups, but I just want to know if this could also help to have a backup.

  Thank you.

  I don't think that Cisco supports snapshots on CUCM.  Please visit the following link: http://docwiki.cisco.com/wiki/Unified_Communications_VMware_Requirements#VMware_Feature_Support_for_Unified_Communications_8.0.282.29_through_10.0

  For snapshots in general, they can be made during the execution of a machine, but I don't know how to react the voice servers.

• Instant snapshot of VMWare and SAN

  How the instant different(or similar) snapshots SAN VMWare?

  Thank you

  The case of use as well as the method of snapshots is very different.

  As NuggetGTR says table instant base will take a snapshot of the entire lun/volume, but instant VM are just for each individual VM.

  How snapshots are created are very different and this determines the use case. EG Netapp table according to snapshots are very effective and take very little space, because (simplifying here) they mark all blocks in the volume in read-only - so you have an overview of the entire volume and because it is not copying all the data it is very fast and not take place.  As new data are written/modified/deleted it says new blocks and blocks alone reading in the snapshot are not deleted or modified.  This makes it very effective and good for backups long term.  However, as this is an array based snapshot is done at the block level and Netapp doent know what data are, could be a SQL database or the virtual machine.  honing to get application-consistent backups, to a plugin abreast of the API as Snapmanager for SQL or VSC for VMware.

  VMware based snapshots of a virtual machine are created by sleep (possibly) the guest operating system and then marking the. VMDK a new read-only. VMDK is created for the virtual machine that will handle the reads/writes new data and the original. VMDK will manage the readings for the old data.  This process is repeated for each snapshot that is taken.

  More the string of snapshots (and. VMDK) files the most impact on the performance of the virtual machine.  Also when you delete a snapshot must merge the. Files VMDK back together which can take a long time and have a performance hit of old clichés.  They will be also eats more space!

  These are intended to serve as a term 'safety nets' shot so that you can quickly return as any change - not as a long-term backup solution.

  They are a great tool to use in conjunction with array-based snapshots.  Using Netapp for example, you can install the VSC in vcenter and use it to plan the snapshots table in conjunction with the snapshots of VMware.

  This will fix a nice snapshot of each virtual machine with a consistent state Vmware hard, then the snapshot of the table will be instant volume/LUN with all these beautiful .vmdks suspended/static, then it will remove snapshots of Vmware.

  Some best practices:

  • The snapshots are not backup. A snapshot file is only a log of changes to the original virtual disk. Therefore, do not count on it as a direct backup process. The virtual machine is running on the most current snapshot, not the original disk vmdk files.
  • Snapshots are not complete copies of the original disk vmdk files. The take a snapshot does not create a complete copy of the original disk vmdk file, rather it copies only the delta records. The changelog in the snapshot file is combined with the original files from disk to be part of the current state of the virtual machine. If basic disks are removed, the snapshot files are useless.
  • Delta files can reach the same size as the original file of the basic disk that's why storage provisioned to a virtual machine grows an amount up to the original size of the virtual machine, multiplied by the number of snapshots on the virtual machine.
  • The maximum supported snapshots in a string is 32. However, VMware recommends you to use only 2-3 shots in a string.
  • Do not use any single snapshot for more than 24 to 72 hours. Snapshots should not be maintained for long periods of time for application or Virtual Machine version control purposes.
  • • This prevents snapshots to grow so large to cause problems when deleting / engaging them to the original virtual machine disks. Take the shot, make the changes to the virtual machine and delete / commit snapshot as soon as you have verified the condition of operation of the virtual machine.
    • Be especially diligent with use of the snapshot on the virtual machines, high-transaction, such as e-mail and database servers. These clichés can develop very quickly in size, filling data store space. Commit snapshots on these virtual machines as soon as you have verified the State of work appropriate to the process that you are testing.
  • If using a third party product that takes advantage of snapshots (such as backup of virtual machine software), regularly monitor systems configured for backups to ensure that no snapshots remain active for long periods of time.
    • Snapshots must be present for the duration of the backup process.
    • Photos taken by software of third party (called via API) may not appear in the Snapshot Manager vCenter. Check regularly for snapshots via the command line.

• Do capacity planning on an existing vmware environment

  In the first phase of virtualization made us build 1000 VM on 120 esx host.

  So we produced vm mass until 2008.

  Now we found the overall architecture X 86, (CF) storage, (1 gigabit) network is very old.

  We believe that we have many pieces of equipment and it is difficult to monitor and that the performance (disk quick access is not very good)

  We thought about to use Scheduler capability to analyze it is VMware infrastructure, to know what we really need for an environment VM 1000.

  But we do not know if the capacity planner has been designed to analyze the vmware environment it self, because it was only used to analyze the physical environment.

  I only know platespin.

  Lanamark (?).

  Free 5nine Planner (?)

  Are there other (free) market

  Vmware capacity planner would be better it self.

  I've done many evaluations of virtualization using Capacity Planner. Many of them were in organizations that have been partially virtualized, so the analysis includes both physical and virtual servers.

  Capacity Planner will identify the virtual servers and mark them so they can be recognized in your inventory.  This is true of virtual machines running on ESX or Hyper-V. I don't have a problem using capacity planner to size a physical infrastructure refresh, and I am sure it would work in your scenario as well.

  Kind regards.

• Extend the VMware environment

  I'm expanding our vmware environment.  I currently have HA\DRS clusters comprising DL360\380 G5 servers.  I bought three DL380 G6 servers.  I'm the thing about creating another cluster for the G6 servers using VMware EVC vs. Someone has mixed the G5 and G6 servers on the same cluster?  Or is it better to keep them separated?

  Thank you

  > Has anyone mixed G5 and G6 servers on the same cluster?  Or is it better to keep them separated?

  VCA depends on the processor not material, if processors are a match, it should be good... We mixed in some, it's only a problem if your servers are a different configuration, so G5 is 64 GB and G6 is 96 GB of RAM for example, then you could end up with an asymmetrical cluster.

  IMHO if the machines are identical (except the new architecture) I would put it in the same cluster. You can always build the new cluster, as expected, disconnect, then remove the host G5 of the old cluster and ADD the new cluster G6 (after turning on VCA).  If she don't get complaint, it should be good

  BTW, removing guests will NOT affect the virtual computer running (provided that you restart / power off of the host).

• Error removing snapshot using vmware-cmd on ESX 3.5

  Hello VMware specialists,.

  whenever I try to delete a snapshot using vmware-cmd ("" / usr/bin/vmware-vim-cmd vmsvc/snapshot.remove vmid ' ") I get the following error:

  {(vmodl.fault.InvalidArgument)

  dynamicType = & lt; unset & gt;

  MSG = "a specified parameter was not correct.

  "

  }

  What is the problem?

  Can someone help me?

  thx a lot

  You have more than one snapshot? in this case, you will need to provide arguments to inform additional cli command which instant you want missing. If you want that all went snapshots just use

  VMware-vim-cmd vmsvc/snapshot.removeall vmid

  Use the following command to get more information on the State of snapshot for VM

  VMware-vim-cmd vmsvc/get.snapshotinfo vmid

• copy a snapshot in an environment different from VMware

  I have a snapshot that is on 33bg

  I want to be able to put this same snapshot on a diiffernt laptop I have

  André procedure is perfectly fine and is pretty much the same thing I posted in a previous thread (the only difference being that the earlier thread concerned move a virtual machine instead of copying a.)

  ------------------------------------------------------------------------

  That's what I would do (it's easy).

  (1) make a folder on the new drive call it D:\vmware say.  All the VM source directory (it will appear at the bottom of the GUI under the Virtual Machine details) and drag it to the new folder of vmware.

  You will have (I use Fedora for example) a new structure as D:\vmware\Fedora\.

  (2) open VMware WS - remove the old VM of Fedora to the library (Favorites) - you must delete no disc that you have already done this.

  (3) use the VMware - .the then file and open D;\vmware\Fedora\Fedora.vmx.  The 'new' Fedora will be identical in all respects to the complete disc (won't be complete now!).  If you receive a message saying done you copy or move the virtual computer course will tell you "move" because that's what you were doing!  Repeat for the other virtual machines you have on the old disk (full).

  (4) If you want to store all new virtual machines you create on the D: drive go to Edition - Preferences and change the location of the virtual machines stored on D:\vmware.

  Of course, you must change the drive letter and the new directory to your liking.

• How to return to the prompt to confirm my deletion of snapshot in VMware Workstation 7.0.1 (Windows)?

  Hello.

  Somehow, I have accidentally said VMware Workstation 7.0.1 does not prompt/confirm when deleting my image snapshots. How can I get that back then he can confirm my requests? I can't find the option in the program or the answer online.

  Thank you in advance.

  Maybe it's because my new glasses

  However, I see the entry (the 9th bottom). Set to "TRUE" or remove them, it should work.

• Screening for the Virus VMware environment?

  Hello fellow VMware users.

  I decided to set up an environment of virtual-screening machine of the virus.

  Other info: don't know if this is important: running an XP Home Edition SP3 - processor Pentium 4-3, 00 GHz - 1 GB RAM

  Under VMware Workstation version 6.5.3 of XP Home Edition

  I would try using NAT, which essentially lets you share the IP address of the workstation host and you can communicate with other systems and the Internet.  I have no advice for you on 'subjects' If you are referring to where you are going to get viruses for the test. The only one I know of we is the well-known Eicar test virus.  You can find it here: http://www.eicar.org/anti_virus_test_file.htm.

  I still think that the safest way to do this is to disable the NIC in total.  You can always transfer files to the virtual machine via shared folders option in the VMware tools and ensure the safety of your host system.  You can transfer new definitions of virus, infected files, and ensure the safety of your host system while having your completely isolated test bench.

  If you end up using this to create a new virus and causing pain for IT administrators around the world, do me a favor and forget I gave him advice.

• If all the domain controllers reside in the VMWare environment

  I was curious to know if there is someone who can give their opinion about the location of the domain controllers in the VMWare community.  I had 2 DCs before the introduction of VMWare and pulling on servers inside.  I created 2 new controllers domain in VMWare and then retrograde 2 those outside so that only there are only virtual domain controllers.  It seemed to work very well, but I had to turn off equipment running VMWare, and when it started, the storage device that the accessible ESX host has launched a mistake because he could not find a domain controller.

  Most people remove all external domain controllers and go with only VMWare virtual DCs, or is it better to always keep an external domain controller upwards and running?  Any advice is welcome.

  Thank you.

  I always advise to keep the domain controller hosting your virtual environment PDC emulator FSMO role. Time is critical on most of the servers, but especially on the PDC that is the top of your Windows Time synch infrastructure.

  We also keep a ms in each data center on a physical platform, this way if we already have a power down when we turn we can raise the physical DC first and very quickly.

  I hope this helps.

  Kind regards

• Automatic snapshot with VMware Server 2.0

  Hello

  My company uses VMware Server 2.0, however we have several virtual and running servers which we want to have an overview of every 24 hours.

  Now ive been looking for this for a while now and I just can't find the way to do it?

  Just to let you know that I don't want to make a snapshot of ALL the servers that are running only 6 of them.

  Could someone please explain to me how and where to change it so my 6 servers will make a snapshot every 24 hours? If possible, it would be nice if I only would keep 2 snapshots in the folder and after that he began crushing others still? Since we only need to go back in time to 24 hours, however, gives us the opportunity to go back to 48 hours max which is sufficient. (not sure if this is possible?)

  Thank you.

  You can try the scheduled task in Windows and vmrun (http://www.vmware.com/pdf/vix160_vmrun_command.pdf)

• Cannot find config.pl - vmware in Server centos 6.4

  I have installed vm workstation 10 in a 6.4 centos server and create a centos VM 6.4. When I turn on the virtual machine, an error message box will appear.

  

  and the command window shows:

  

  but I can not find vmware - config.pl on the server.

  So, what should I do then?

  Try the command "vmware - config.pl to locate.

  Solution: This error is the vmware or etc/init.d/vmware startup script, because the executable vmware checks to see if the VMware modules are loaded and if not, it calls the vmware startup script to load.
   
  etc/init.d/VMware, checks if the file/etc/vmware/not_configured exists - and if so, it issues the above error:

  The solution: delete the/etc/vmware/not_configured!
