• vCenter 5.5 - error Grub hot-cloning Ubuntu 12.04

  Hi All-

  I'm having a pretty hot-cloning time of a Ubuntu 12.04 VM from virtual server to another virtual server.

  Two virtual servers are running ESXi 5.0.0 build 623860.  I use VMWare vCenter Converter Standalone Client 5.5 build-1362012.  The virtual machine in question is under Ubuntu 12.04.2.  The virtual machine is using LVM, I read may have an impact.

  When you run the converter, I get to 97-99% done, then get the following error:

  an error occurred during conversion: grubinstaller::installgrub: /usr/lib/vmware-converter/installgrub.sh failed with return code: 126 and message: chroot: cannot run ' / vmware - updategrub.sh': exec format error

  vmware runtime error - updategrub.sh through chroot into/mnt/p2v-src-root

  /usr/lib/VMware-Converter/installgrub.sh: line 143: / mnt/p2v-src-root: is a directory

  I looked all over trying to find someone who has got this exact error message, but can't.  I tried these steps but were unsuccessful.

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 2052628

  If someone has all understand why this error occurs, how to fix, etc, it would be greatly appreciated!

  Well... Finally, I've advanced and rebuilt the server vCenter Converter Standalone was running on.  I then did a new install of the converter and revived the task and all is well.  I think it could be a matter of the wrong version *.iso being mounted as the aid of the converter.  I had to keep manually mount the iso on the new VM and start before he would go actually through, and sometimes I could get invited to "converter" identifiers.

  I will be chalked up a junk of update/install/accumulated bad on the system of vCenter.

• Error recovering hot cloning backup - 10 g

  Hello
  I use oracle 10g (10.2.0.1) with linux4
  I'm cloning a database with hot backup
  
  but I get an error when I run the
  
  RECOVER THE DATABASE BACKUP USING BACKUP CONTROLFILE UNTIL CANCEL.
  
  
  See my procedure:
  
  start of the db
  ALTER database begin backup
  take backup of the file redologs, data files and archiving of newspapers as well, spfile and pfile.
  ALTER database backup controlfile to trace.
  alter database end backup;
  -so far the hot backup is done.
  
  
  
  now, I copied the backup files to the new directory clone db structure. The structure just like any other db directory structure.
  
  Now, I created a new pfile from the existing database.
  start-up of the new db clone with the new pfile in phase nomount
  
  Now, I created the new control file.
  the control file is created successfully
  copy the backup control file to the udump directory in the new comic book of clone.
  
  Now, I want to apply new clone db archives.
  
  When I start the

  I get a message saying that there is an inconsistency in the wire sequence
  
  
  
  Tried both possibilities such as specifying the redo logs and the location of the newspapers archives from the back to the top and the new clone system, but I can't solve it.
  
  can someone help me what to do
  
  Thanks in advance.

• Hot cloning - let the physical server running then?

  I have a question for the Vmware Converter. If I understand correctly, you can use hot Clone to clone a physical server while it is running. Of course, that seems very well so you don't get no downtime during conversion.

  But, if the reason for this conversion is to migrate from physical to virtual, what happens if the physical server continues to operate after the conversion? Even just a minute can be enough to have changed the original system, perhaps a database or other stuff, that will make the new virtual instance "incorrect."

  So how does this normally? If you want to virtualize a server that has a system that interacts with users either or other servers, how will stop instantly change?

  OK, even if you are in your downtime window it would be preferable to perform the validation of the server application.

  What we normally do, is check the event logs and do well for sure there no new errors that are produce after the p2v (physical 2 virtual), especially application or system related event.  We will also perform a few reboots of the (virtual) system and sometimes we also had to remove some old drivers.  We have sometimes came across problems with NETWORK cards keeping the old ipconfig when migrating.

  When supply us the new VM give us it a whole new value of intellectual property and test it with the other physical system down.  After correct validation go us ahead and leave the virtual running.  We usually have to master the physical machine in the datacenter for about two weeks and then begin the process of decommissioning.

  One thing most definitely, you want to do is make sure to install vmware tools on the virtual server.  I know it's probably obvious, but many people forget.

  Hope this helps,

• Cloning and cloning live (HOT)

  Hi all

  I can't seem to remember the requirements allowing to clone and direct cloning.  The host needs to have shared storage and the same CPU family?  What else is necessary?

  Thank you

  There is no requirement regarding the CPU compatibility or shared storage - Hot cloning makes a copy of the virtual machine so it not there no similar to vmotion requirements.

• Can you hot clone and keep up to date data?

  I am in need of warm cloning of a physical machine (P2V) and cannot afford the downtime to cold clone.  The server is a file server, and some files may change during the day when I'm hot cloning.  Is there a process or the converter inteligent enough to check for changes to files at the end of the clone?

  Also what is the cleaner to turn off the old physical server and put it way up the new virtual?

  Thank you!

  Actually I meant Converter Standalone 5.0

  4.3 cannot schedule synchronizations.

• EBS R12.2.4 db backup and restore

  Hello

  I need to make a database backup for security reasons. How I had to do in EBS? with expdp (.dmp) and a restoration with impdp (.dmp)

  or what is the process?

  Thank you.

  Luis.

  Hello

  Do not use the import/export for backup and restore. They are generally used to migrate a database to a new server or as an alternative to an upgrade of database.

  You must use RMAN after enabling archivelog mode.

  It allows you to perform backups hot, cloning of the database and many other things.

  If you don't/can't use it, you can make a cold backup of the database files.

  Kind regards

• P2V Ubuntu 10.04

  Hello

  I'm trying to P2V a couple of Ubuntu server using the Converter Standalone client 5.1.  I tried to enable sudo to not use passwords, as described in the following article VMware KB: enable the use of a non-root user to hot cloning of a source Linux machine

  I also tried to simply enable the password for the user root by this announcement.  Ubuntu 8.10 P2V sudo
  

  All with no luck.  I have attached the log of the worker and the server log.  It seems that the server may be seen killing my connection.  Any thoughts?

  So I was able to understand what was going on.  At the launch of clone volume mounted on "/" Stadium IPADDRESS, the converter would convert the drive.

  At one point, the network interface would be.  I don't know why.  The work around is to go on the physical computer that you try to P2V and run the following commands.

  sudo ifdown - a

  Stop all network interfaces

  sudo ifup - a

  This starts all network interfaces

  This makes the P2V will continue.  It's a weird problem, but I'm glad that I was able to understand.  I hope I save another several hours of troubleshooting!

• Director of the laboratory of vCould Migration

  Finally, we started with a proof of concept in lieu of LM vCD. Still everyone has a few best lessons learned? Networking seems to goo, but has yet to be understood. Plugin remote desktop feels worse.

  -What is the best to do with workspaces?

  -What is a mapping of good organization? For example, for access to the network resources?

  -Is anyone has seen yet, how make an export full of all virtual machines in a paralytic (for example as a backup?)

  Stop the VAPP stops it.  By default it just turns off the virtual machine.  You can change it to a soft stop via the good operating system in the properties of vApp.

  Hot cloning can be done via the user interface, but can be done through the API.  It's the same for the extension of disk space.

• Convert a server running ESXI4

  Hello

  I have a small question... I want to convert a Windows Server 2003 running for my VMware ESXI4 using VMware Converter, no problems so far.

  My question is what happens to the files that are written to the server, while the conversion is being performed, they are copied too or they fall?

  Greetings,

  Pinke

  Converter can be set to synchronize changes made to the file.  This is page 11 of http://www.vmware.com/pdf/convsa_43_guide.pdf.

  You can set Converter Standalone to synchronize the destination with the source machine virtual machine
  After hot cloning. The synchronization is performed by the transfer from the source to the destination blocks
  that have been changed during the initial period of cloning. To avoid the loss of data on the virtual machine of destination,
  Converter Standalone can close some Windows services before synchronizing. Based on your
  parameters, Converter Standalone stops the selected Windows services so that no critical changes occur on
  the source machine, then the destination is being synchronized.
  Standalone converter can stop the source of the machine and on the destination of the machine power when the
  conversion process is complete. When combined with synchronization, this action allows a transparent migration
  a source of the physical machine to a virtual machine of destination. The destination machine takes over from the source
  operations of the machine with minimum downtime.

  If you look through the doc there are certain limits and restrictions for this.   I suggest you stop services (database, Exchange, file sharing, etc.) before the cloning process.

• Best method to move virtual machines Linux of VC 2.5/ESX 3.5 to 4.0/ESX4 vCentre

  Guys,

  I have to move a number of them. The two groups are there. If it is not a question about the upgrade of the VC/ESX. I want to use the simplest method possible to move these VMs and here's my plan:

  1 copy the whole directory of VM from the data store on VC 2.5 to the data store on vCentre 4.

  2. Add the virtual machine to inventory in vCentre 4.

  3. upgrade VMware tools

  4. switch to hardware version 7.

  And that's all. Please let me know if this plan is feasible, or more importantly, no holes in the plan.

  Thank you

  Hello

  You have a few options:

  1. you can bring up the old data store for ESX 4.x and save the VM on vCenter 4.0.

  2. you can add that the host ESX to vCenter 4.0 3.5 move virtual machines in ESX 4.0 cluster.  You can use vMotion and Storage vMotion, according to your needs.

  3. you can use the stand-alone converter to make a hot cloning of Linux virtual machines in ESX 4.0.

  Best wishes / Saludos

• How does the syncronize feature of VMware Converter 4.2 works?

  The storytelling administration guide follows writes:

  http://www.VMware.com/PDF/vsp_vcc_42_admin_guide.PDF

  Page 10

  You can configure vCenter Converter to synchronize the destination with the source machine virtual machine after

  hot cloning. The synchronization is performed by the transfer from the source to the destination blocks which

  changed during the initial period of cloning. To avoid the loss of data on the virtual machine of destination,

  vCenter Converter can close some Windows services before synchronizing. Based on your

  settings, vCenter Converter stops the selected Windows services so that no critical changes occur on the

  source machine so that the destination is being synchronized.

  From my point of view, it works as follows:

  1.) hot clone of the source to the destination virtual computer computer

  Synronization 2) takes place directly after hot cloning, to get the delta during the initial period of cloning.

  Page 11

  TO

  make sure that the destination virtual machine retains all the blocks that have changed in the source system during

  the first cloning of process, select the Sync feature. With synchronization, if a change occurs

  on the source machine during the initial conversion, vCenter Converter copy to the destination machine

  after the initial conversion is complete.

  The technique that is used to nothing: Windows VSS snapshot

  Page 28

  Restrictions related to the creation of snapshots of Windows Sources

  vCenter Converter uses snapshots VSS to save the State of the source volumes during the hot cloning of physics and

  virtual machines that are running Windows. Instant VSS are also used to synchronize the virtual destination

  machine with the source machine after the initial conversion. Some of the issues related to VSS are inherited in

  vCenter Converter and can prevent the successful completion of your conversion tasks.

  3.) only the combination of the service with synchronization to stop makes sense.

  Page 53

  You can ensure that you don't lose data services that are running on the source machine. You can select

  Which services to stop before vCenter Converter synchronizes the data between the source and

  destination machine. Accordingly, the services do not result in data while the computer source and destination

  are synchronized.

  Import a Windows powered machine means that vCenter Converter copies the data from the source

  machine to the destination machine, while the source computer is still running and generate changes.

  This process is the first transfer of data. You can transfer data for the second time by copying only the

  changes during the first transmission of data. This process is called synchronization.

  What does the second time? I can do the following:

  Back to Monday from 20:00 to 24:00 the Hotcloning of the physical server to virtual.

  Then, to Tuesday 20:00 synchronize the physical server with the virtual and stop the physical server.

  I think that's not possible, two separte the first and the second stage.

  Page 55

  Synchronize the Destination Machine with the changes from the Source Machine

  Import a Windows powered machine means that vCenter Converter copies the data from the source

  machine to the destination machine, while the source computer is still running and generate changes. This

  process is the first transfer of data. You can transfer data for the second time by copying only the changes made

  during the first transfer of data. This process is called synchronization.

  Synchronization is available only for Windows XP or operating systems later source.

  If you resize volumes FAT or shrink NTFS volumes, you cannot use the sync option.

  Prerequisites

  Stop services of source to make sure they don't generate additional changes during synchronization.

  that could lead to data loss.

  Must serve it it I can only do this at the start time of the conversion, when the wizards to configure the conversion tasks is selected.

  In all of this means for me that with synchronization window maintaince than AI based on time, how long is the synchronization and the closure of the physical server and power on the virtual machine.

  Converter 4.2, synchronization occurs just after the cloning process and therefore changes occurred to the source during the period of cloning are also applied to the destination machine. Now, with this version of the converter, it is not possible to separate the tasks of synchronization and cloning (i.e. you can't clone the machine Monday and synchronize this Tuesday).

• How to manage the SAN relating to software, when we import machine which is connected to FC SAN?

  Hello

  There is a Windows Server 2003 running SQL Server with 2 local HD and 1 HD on FC SAN.  We would like to import this machine to a virtual machine.

  (1) initially, we would like to convert by cold cloning, but it seems that it is not a good choice, because we are not able to access the SAN for cold cloning.  This means that the hot cloning is the only choice for us?

  (2) there are programs like: Qlogic SANSurfer / Navisphere Agents / EMC PowerPath installed on this machine.  What will be the best way to manage these software?  Since we don't use them in VM, should remove the virtual computer or disable these services during P2V?

  (3) is there a problem when you import data / change the size of the disk for the one on FC SAN?

  Your opinion is requested.

  If we opt for cold cloning, this means that after P2V, we

  (1) remove the LUN from the physical machine in Navisphere Manager

  (2) add the logic unit number to the host ESX Cluster

  (3) add as RDM LUN to the virtual machine?

  Right.

  Between 2 and 3, you must make a new analysis of storage to see the new LUNS.

• Converter offline iso cold

  Hello

  I would like to find a way to get iso cold start VMware Converter.

  I can't find any good information about it, even if you can read this here

  ' Is there a compatibility list for VMware vCenter Converter, similar to the one for P2V Assistant? . " There is no list of hardware compatibility for VMware vCenter Converter. VMware vCenter Converter supports and recognizes most of the types of server hardware. VMware vCenter Converter provides two mechanisms of cloning: cloning (live migration) and cold cloning (cloning using a BootCD) Hot. With hot cloning, VMware vCenter Converter communicates directly with the guest running on the physical computer operating system source as such has no direct hardware level dependencies. With cold cloning, VMware vCenter Converter BootCD provides a boot environment to Windows PE, which provides support for the latest hardware and is thus able to recognize most physical server systems. For cases where the VMware vCenter Converter BootCD does not recognize the physical hardware source, VMware provides a utility that allows administrators to download the necessary storage and drivers card network provider's Web site and the downloaded drivers to inject into the BootCD distribution. This can be used to create a new Converter BootCD image that will help recognize the system hardware. "

  Thank you for your answers...

  Hello

  To download the converter cold clone cd, I guess you need log in the portal to vmware.com and you need VMware vCenter Enterprise Edition to get an option to download the cd.
