• Create a virtual machine using the ubuntu (host of W7) partition

  I am running Windows 7 and 8 of VMware Workstation.

  The disc is actually a raid-0. There are 3 partitions: (Dual-boot)

  -Ubuntu (64-bit)

  -System reserved Windows

  -Windows (64-bit)

  I am trying to create a virtual machine under W7 using the Ubuntu partition.

  I tried 2 things for step 'select a physical drive:

  -Use individual partitions. The problem is at the end, when you click Finish. I get the error: "one of the provided parameters is not valid."

  -Disc use whole. The virtual machine is created, but when I turned on, I get the error:

  "Could not open the disk ' C:\. [..] \Ubuntu 64 - bit.vmdk' or one of the snapshot disks it depends on.

  Reason: the physical disk is already in use. »

  Thank you in advance for answering,

  Kind regards.

  In my tests I couldn't use a host physical diskwith a Windows 7 without setting the disc 'offline '.
  But then you can set the diskette from Windows Startup 'offline '.

  Using Linux or 2003, you don't have this problem.

• Several Host Isolation

  Imagine a scenario where we had a HA of four nodes cluster spread on a campus with two nodes in one place and two in the other. What would the host isolation response if the network connection between the two sites has been lost?

  If we lose a host then the TI is known to be isolated after 12 years and then failed aftet 15s. If we lose two, however, nobody is isolated and I am assuming that nothing happens.

  Now; Imagine that we have warehouses of data which are all shared, but some are in one site and some are in the other. Guests running on local data warehouses would be unaffected. Guests who are running on data warehouses remote fails. The question is: what will happen to the hosts failed?

  Thank you

  Warren Barnes

  Before you answer this in detail, I want to make sure I'm clear on my assumptions:

  1. There are 4 hosts in the cluster, two on each side of the stretch. If this is the case, then all 4 hosts are primary. (The first 5 guests in any cluster are primary, so you get only secondary when there are 6 or more hosts).

  2 If the network fails between the two sites, storage will be split-brain as well? I guess that Yes, based on one of your comments.

  If, in view of the #1 site hosts A and B, and site #2 a hosts C a D...

  If, after the split between site 1 and 2, and B can still heart rhythm with each other, and C and D can pulse between them then there is no answer tried insulation. Answers insulation kick only in when a host can not with any of the other primitives of the heart rate, and it can also ping the address of isolation (usually the gateway (s)) for networks that host is on.

  So what happens is that A & B site 1 to conclude that C & D at site 2 have failed. And vice versa. A and B will try to power - on the virtual machines that are running on C and D, even for C & D - they will try and power on virtual machines that have been on A and b. Now, because the storage of some virtual machines can be found at site 1 and storage other virtual machines are at site 2, some of the power-ons may fail because the storage is not accessible. But as A & B will attempt to power on the set of the VMS C & D and C & D will attempt to power on the set of virtual machines of A & B (that means that admission control allows all of these power-ons) then each VM will end up under tension correctly on each site 1 or site 2.

  Now for the ugly part - if any of the VMS to site 1 lost their storage in the score, or vice versa, then the vmware-vmx process who represent these virtual machines always operate on one or more hosts on the side of the partition that has lost the storage and there is now a process vmware-vmx representative the same virtual machine running on a host across the partition that has now acquired a lock on this VM. None of this is a problem until the partition joined. This is so the behavior described by Elisha happens - that is to say the virtual machine appears to bounce back between the two hosts until the answer to the question on the lock lost by pointing the VC client directly to the host. And as he pointed out, the question will be auto-répondu by VC to vSphere 4.0 U2 and above.

• Cannot suspend 500 GB partition on SAN for backup

  I'm under Vsphere ESX 4.0 Update 1 backup on a Windows 2003 server using Symantec Backup Exec 12.5  This 2003 server, I have a 750 GB partition on the SAN, which is used as Proxy VCB.  I'm under seven virtual servers Windows 2008 R2 and a Windows 2000 Server.  All the virtual hosts have second partitions that are mapped to the raw LUN.

  Can I save all the virtual hosts except a Windows 2008 R2 host.  This host has a 500 GB (488 GB formatted) LUN on the SAN.  All other hosts are less 200 GB on the SAN LUN.    I checked that the VCB Proxy Server sees the 488 GB LUN.  The Backup Exec job fails with the following error:

  V-79-57344-38220 - Virtual PC "FS3" backup failed. VMware VCB framework reported the following error

  Error: another error occurred: failed to create snapshot: could not suspend a file system.

  If I remove the LUN from the host Windows 2008 R2, the backup operation is complete.  If I add the LUN to return in, it fails again.  The virtual host is not yet in production, and the partition on the LUN is always a 488 GB vacuum.  So far, nothing is installed on this host except VMware Tools.

  The problem seems to be that the backup process cannot suspend this large LUN.

  Do I need a prior custom freeze and thaw the scripts?  If so, which should contain it?   Is there anything else I should look at to get this partiion to back up?

  So the problem is this file delta for the snapshot can grow up to the size of the original, in your case 500 GB disk, but the 1 MB block gives the maximum of 256 GB file size. To prevent such a situation ESX fails to create the snapshot.

  You need 2 MB block, at least on the data store with the virtual machine files, so it would allow you to create files up to 512 GB

• How to install a dual boot on my laptop system. There the Vista license on it, I'll buy a disc of windows 7 retail of the school?

  How to install a dual boot on my laptop system. There the Vista license on it, I'll buy a disc of windows 7 retail school, also I want to use vmware or virtual box to have windows 7 Windows 7 for experimentation (because in to school for computers). So, how can I configure my computer to ask what os I want to run from the black screen and I have 7 on a virtual machine to play with and what having a vdi with my os to travel around with on a USB?

  Please see the following article with useful information about dual-boot:

  http://Windows.Microsoft.com/en-us/Windows7/can-I-have-more-than-one-operating-system-on-my-computer-multiboot

  You will not be able to virtualize Windows 7 because the license would be already physically license on the host on a partition.

  Another question, you must make sure that the copy of that school license is not an upgrade. You cannot install an upgrade on a partition or a virtual machine.

  If ESXi hosts are still able to communicate with each other via a network that is enabled for management, the host is not partitioned.  Do you have other vmk interfaces enabled for management traffic?  If so, the two hosts would still be able to communicate with each other and would not be considered an event of host isolation.

  Take a look at the excellent deep dive HA post of Duncan.

• VMS in an external facing DMZ

  We are currently implementing a new Vmware VI 3.5 environment to host the external/public address applications.  The ESX host themselves cannot be accessed from outside of the corporate firewall.

  Are there any special settings I should add to my virtual machines to increase security?  I think more along the lines of the settings of advanced configuration for the virtual machine itself, not the guest OS.

  Thank you

  Hello

  Chapter 8 of my book which includes a host of insulation parameters that must be set to the virtual computer. Hardening guides are a subset of these.

  But yes, you will need to set the parameters of insulation minimum in hardening guides or even more what is in the book. I would serious consider whether or not the paravirtualized drivers are necessary for these virtual machines that they are attack points "escape the VM ' current.

  I would also increase the surveillance of these virtual machines for the use of resources as well. Increased use is often a sign of an attack.

• New addition ESXi host to vSAN, put in the new group of network Partition

  Add a new R730xd from Dell to my cluster active vSAN (also all the Dell R730xds, same features), but when doing so, the new host is put into another group of network Partition.  Same configuration of the switch, the new host is plugged as that of others.  Can check the connectivity between each host (in addition, confirmed as much as I can ping to the interface vSAN between one of the four hosts), yet always says there is a communication error.  Any ideas?

  Certainly a multicast problem, strongly recommend the reading of these:

• Recommendations for "Standby" host / creation of an additional data store / system partition

  My ESXI host 5.0, as well as several virtual machines in the data store, resides on a drive of 500 GB of aging.

  I have a disc of 2 TB to spare I would partition to as a standby host and an another data store containing the virtual machine, whose thinking is that when the 500 GB drive goes down, I can boot from the 2 TB drive and the new.

  I'm looking for suggestions for the best option to implement.  Thoughts include:

  1. A new installation of ESXI on 2 TB drive and restore the configuration from a backup "vicfg-cfgbackup" of the host of 500 GB
     1. have two partitions VFMS, one, a "backup" of the current data store containing the VM on the 500 GB drive and the second is a "general" datastore ~1.5TB that I can use for a volume of FreeNAS; or,
     2. have a bigger VMFS partition
  2. Partition my drive from 2 TB to allow later installation of ESXI; and two partitions VFMS (one of the same size as on the 500 GB drive and the second using the remaining space available), or a single VMFS partition

  Proceed to option (1) would result in two disks with ESXI hosts on a machine, but probably, because they are not clones, the UUID must be different so there is no problems with the discs being active.  I just need to set the BIOS to boot from the correct disk.  I understood this correctly, and if so, are there other potential problems with this approach?  The process of installing ESXI allows multiple VMFS created on the a drive, or this work manually through the command line interface, or the vSphere client

  The second approach is possible, and would I partition the same drive the 500 GB (IE several partitions of LinuxNative, a systemPartition, a vmkDiagnostic and a vmfs partition), with an additional partition VFMS (or a large VMFS partition)?  Or is it not possible to install ESXI on a disk with partitions that must be kept.  From what I've seen, it seems that if the Setup program detects that the drive has [a] [s] of data store, then the option is provided for the upgrade, so maybe it's possible to install ESXI on a disc with pone or warehouses of VMFS more data on the disk...

  Or maybe there is a third option that would be best.

  Any advice?

  Hi Ray,

  If you have just a 500 GB drive in your host 5.0 store the ESXi and your VMX/VMDK virtual machines then why not just do the following.

  1. Remove the 500 GB drive
  2. Insert the 2 TB drive
  3. Install ESXi 5.5U2 (or 5.0, if you still need a compatibility it provides) and partition your drive from 2 TB to choose from including data storage you want.
  4. Turn off and add the 500 GB drive (or place it in a networked PC or in a basket usb)
  5. Power and copy the vmx/vmdk files of the 500 GB to your new store of data and add virtual machines to the inventory
  6. Now periodically instant and take backups of your virtual machines to your 500 GB drive (by placing it in a USB port or network caddy/PC)

  What's an option 3?

  Concerning

  Chris

• Can you have different partitions on a virtual machine on different host machine partititons?

  I have a 2008 srver machine which has two partitions. I wish that my virtual machine which is Server 2008 (Workstation 8) to have one of its virtual disk on one of my partitions hosts and the other on the other partition. IS this possible? Any guidance would be greatly appreciated.

  With a new virtual machine you would just select the location for the new virtual disk when you create it. With an existing virtual machine, you could - with the virtual machine powered on and closed VMware Workstation (or at least tab of the virtual machine closed) - move the virtual disk files second to another partition and edit the .vmx virtual machine file and add the absolute path name of the virtual disk file.

  If you want, after (join) current .vmx file of the virtual machine as well as his latest vmware log file and let me know the path target if I can guide you.

  Do you have any suggestions?

  Thank you

  It sounds like this host has already been improved 3.x! In this case you will not be able to upgrade to 5.x using the Manager to update because of the small partition/boot (99 MB).

  to remedy the hosts against a basic upgrade

  ... You cannot use Update Manager to upgrade to 5.0 ESXi host, if the host has upgraded ESX 3.x to ESX 4.x. These hosts have not enough free space in the partition/Boot to support the process of update Update Manager. Use either interactive or scripted upgrade.

• How can I automate the creation of a partition from scratch for a large number of hosts?

  I would like to help with the following steps to cerate a partition scratch on all hosts that have no script, then reprot back to me which guests were to have created.

  all my ESXi hosts have a LUN to start with the space, all the boot LUN are named with the same naming that is conveiton "hostname-localstorage.

  I would like to come up with a script that will check each host in a cluster for a partition of scaratch, if it does not create the folder ".locker -hostname" on local storrage and then set the partition scratching to the new location. Then the new report to me, which is already a partition from scratch and those to whom he owed create a parition scratch to so I can plan then a good time to put the hosts with newly created partitions scratch mainenance mode and restart their.

  I glued the manual way to do it below. I'd appreciate any help anyone can give and it will be well appreciated. I try to avoid to do 1000 hours below. Thanks in advance...

  Note: Before you begin, make sure that/tmp/scratch exists. If it does not exist, create it by using the command #mkdir/tmp/scratch.
  1. Open a command prompt where the PowerCLI is installed.
  2. Connecting to host ESXi using the command:
     
     connect-viserver ESXHostnameOrIP
     
     
  3. A list of the data stores accessible by using the ESXi Host command:
     
     Get-Datastore
     
     
  4. Mount a read/write as a PSDrive data store using the command:
     
     New-PSDrive -Name "mounteddatastore" -Root \ -PSProvider VimDatastore -Datastore (Get-Datastore "DatastoreName")
     
     
  5. Access the PSDrive new using the command:
     
     Set-Location mounteddatastore:
     
     
  6. Create a directory named only for the ESXi host using the command:
     
     New-Item "DirectoryName" -ItemType directory
     
     For example:
     
     New-Item ".locker-ESXHostname" -ItemType directory
     
     
  7. Check the current value of the ScratchConfig.ConfiguredScratchLocation configuration with the command option:
     
     Get-VMHostAdvancedConfiguration -Name "ScratchConfig.ConfiguredScratchLocation"
     
     
  8. Change the ScratchConfig.ConfiguredScratchLocation configuration option, specifying the full path to the directory created in step 6, using the command:
     
     Set-VMHostAdvancedConfiguration -Name "ScratchConfig.ConfiguredScratchLocation" -Value "/vmfs/volumes/DatastoreName/DirectoryName"
     
     For example:
     
     Set-VMHostAdvancedConfiguration  -Name "ScratchConfig.ConfiguredScratchLocation" -Value  "/vmfs/volumes/Datastore1/.locker-ESXHostname"


  9. The ESXi host in maintenance mode and restart so that the configuration change to take effect.

  I have something similar to use the script below.

  I think you'll find that your out in there.

  $configName = 'ScratchConfig.ConfiguredScratchLocation'
  
  $mode,$warn = Get-PowerCLIConfiguration | %{$_.DefaultVIServerMode,$_.DisplayDeprecationWarnings}Set-PowerCLIConfiguration -DefaultVIServerMode "Multiple" -DisplayDeprecationWarnings:$false
  
  Get-VMHost | where {$_.ExtensionData.Config.Product.ProductLineId -eq "embeddedEsx"} | %{    Connect-VIServer -Server $_.Name -User root -Password MyPswd    $scratch = (Get-VMHostAdvancedConfiguration -VMHost $_)[$configName]    $tgtName = ".locker-" + $_.Name.Split('.')[0]    if($scratch -notmatch ($tgtName + "$")){        $ds = Get-Datastore -VMHost $_ | where {$_.Name -match "localstorage"}        if($ds){            Set-Location -Path $ds.DatastoreBrowserPath            New-Item $tgtName -ItemType directory            Set-VMHostAdvancedConfiguration -Name $configName -Value ('/vmfs/volumes/' + $ds.Name + '/' + $tgtName) -Confirm:$false            Set-VMHost -VMHost $_ -State 'Maintenance' -Confirm:$false            Restart-VMHost -VMHost $_ -Confirm:$false            Set-VMHost -VMHost $_ -State 'Connected' -Confirm:$false        }    }    Disconnect-VIServer -Server $_.Name}
  
  Set-PowerCLIConfiguration -DefaultVIServerMode $mode -DisplayDeprecationWarnings:$warn
  

  It uses the DatastoreBrowserPath that Vitali has suggested.

• Partitions on SSD for the hypervisor host of vSphere5 (Free Edition)

  Hello

  This will be my first installation of a system of 5 hypervisor vSphere (Free Edition). My new PC will contain an SSD (120GB) for the vSphere host and VMs. in addition, it will contain a RAID controller with multiple SATA drives for data. My questions are:

  Do I have to create partitions on the SSD drive for installing vSphere 5?

  I read on http://vmetc.com/2009/07/22/best-practices-for-vsphere-esx-4-service-console-partitions/

  There is several necessary partiotions. Is the installation program automatically creates those partitions?

  Is it possible to store the computer virtual (System of each operating system partition) on this SSD also?

  I will store VMs for 2 x Windows7 (approximately 2x30GB), 1 x FreeNAS, 1 x Linux for Zarafa, 1 x Linux for many other services.

  Kind regards

  Oliver

  Hello and welcome to the forums.

  Do I have to create partitions on the SSD drive for installing vSphere 5?

  No, the installation program will take care of everything for you.

  Is it possible to store the computer virtual (System of each operating system partition) on this SSD also?

  Yes, the installer will create a VMFS on the SSD volume where you can place these files.

  Good luck!

• ESX host with local storage recommended for the host partition table?

  Hi all

  I know that the best practical partition table should look like this:

  Mount Point	Partition	Size	Description
  		/ dev/sda (primary)
  / Boot	ext3	250 MB	Change of extra space for upgrades
  N/A	SWAP	1 600 MB	Change the maximum size of Exchange service console
  /	ext3	5120 MB	Change of extra space in the root
  		/ dev/sda (Extended)
  / var	ext3	4096 MB	Create partition to avoid an overflow of root with log files
  / tmp	ext3	1024 MB	Create partition to avoid an overflow of root with temporary files
  / opt	ext3	2048 MB	Create partition to avoid overfilling root with the log files of VMware HA
  / Home	ext3	1024 MB	Create partition to avoid an overflow of root with agent / user files
  	vmkcore	100 MB	Pre-configured

  However with a system with local storage would you set it up the same way, and whatever it is must be amended to change to get ESX to write log files to the different partitions?  I would like to configure it for future expansion for when the enterprise package is configured.

  Yes, I would set up the same way with an ESX with local storage server and nothing needs to be changed for the vmekernel right at the partition/var - unless of course you want to write to a log server that you need to change a configuration file to point to the server logs.  If you talk to the ESX Enterprise license you willnot have to change partiition table-

  Also on something else if you don't have a SAN/NAS storage you will also need to create a VMFS partition on the local data store to host your virtual machines
