• How to change network name for all virtual machines within the same cluster

  We have recently changed name vswitch to take into account that something significant, in the past vCenter could change the labels of networh for all virtual machines... seems this time help labels are not changed (maybe its got something to do with the update vcenter for 2.5.U3)...

  in any case, someone at - it a powershell script that could find all the virtual machines that are referring to the old label network and then changing again the name... ?

  Enjoy the respponses...

  Thanks in advance

  A few things on this blog could help.

  If you know the names you want to use, you could also just use something like:

  Get-Cluster X | Get-VM | Get-NetworkAdapter | Where { $_.NetworkName -eq "OldNetwork" } | Set-NetworkAdapter -NetworkName "NewNetwork" -confirm:$false
  Get-Cluster X | Get-VM | Get-NetworkAdapter | Where { $_.NetworkName -eq "NewNetwork" } | Set-NetworkAdapter -Connected:$true -confirm:$false
  

• How to make a submission even as RDM for two Virtual Machines

  Hi I have a question.

  We have a server ESX4.0 with two Virtual Machines running on it. I presented a 100 GB of SAN storage to this particular ESX host, this storage space must be shared between two virtual machines as RDM.

  But when I add this storage on a computer virtual as RDM, it does not allow me to present the same storage another VM, of RDM is displayed under the name hidden. Is it possible to do so.

  Kind regards

  Khurram Shahzad

  This is only possible with the MSCS clustering functionality.  With the same logic unit or disc number to multiple hosts without clusting will damage the volume of data / as the new system will try to initialize the disk.

  Your RDM may also need to be in virtual compatibility mode to do this.

  The guide of vmware on clustering with MSCS and there should be information about it.

• No network connection between the virtual machines on different hosts ESXi

  I have several 5.0 ESXi hosts in a cluster managed by vCenter Server 5 and I have network problems:

  1. [Host A] running a virtual machine can ping any other computer virtual running on the [host A] great!
  2. A virtual machine running on host [B] can ping any other virtual machine running on [B] home - very well!
  3. [host A] (from the ESXi console) can ping any virtual machine running on [B] home - even better!
  4. [B] home (from the ESXi console) can ping any virtual machine running [host A] - beautiful set!
  5. A virtual machine running [host A] can not ping any virtual computer running on host [B] and vice versa - bad, very bad!

  So basically the problem is that the virtual machines can communicate on hosts. It is a major problem that I need to fix, for obvious reasons.

  Networking on all hosts is configured exactly the same way: a unique and standard vSwitch with a pair of gigabit network cards grouped, vmkernels configured for the vMotion, NFS and network management and a group of ports configured for the VIRTUAL local area network used by the VMs. (vMotion works fine on hosts, storage vMotion works very well too.) All virtual machines are servers Windows (2003 and 2008).

  Reason #3 and #4 above, my assumption is that #5 must be the result of an ESXi/vCenter configuration issue and not a problem with the switches of material upstream. Is this a reasonable assumption?

  Whatever it is, can anyone offer suggestions on how can I fix? It is quite annoying as I'm pretty sure that these hosts are configured in the same manner as those of our production cluster, which does not at all these problems!

  Thanks in advance for any help you guys can provide.

  To be honest, it looks like a problem with your physical network-

  How is the physical network configured - are NIC connects it to the same physical switches? Are the virtual machines on the same subnet? If this is not the case, they are able to ping the gateway sbnet? Can you piing host IP address from the virtual machines?

  I also moved it to a forum more approiate.

• Dedicated network adapter to the virtual machine and the host computer not let can visit his profile

  OK, here's my question, I know how to give themselves a phyiscal nic to a vmware, but I wanted to take it one step further and do not leave the host send or receive data from this network card, only the virtual machine can use this network/NIC...

  Here's my reasoning, I have to network conections, one is for my internal/field network and the second is a direct connection to the internet (Comcast) I don't want to use to separate the machines have for internet connection, I want to be on the same machine phyiscal and have just the vmware machine talking to comcast... is it possible?  I am running VMware workstation 7, last update.

  Thank you

  Cdrshm

  I assume you are using a Windows host?

  If Yes...

  -first set up networking networking with vmnetcfg.exe

  -assign vmnet0 to the network card for the internal network

  -assign vmnet2 to the network card used for direct access to the internet

  -Right-click on the map network-icon in the systray and access the properties of the network adapter for vmnet2

  -Disable all other protocols and the Protocol of vmware_bridge for this network adapter

  result: a virtual machine that uses vmnet2 can directly access the internet and the host has no IP address for this network adapter - and therefore cannot use it.

• Network connections for the virtual machine

  I have recently (1 year) past my office from a Windows computer to an iMac under 10.5 and VMware Fusion. My virtual machine is a member of our corporate domain.

  I can log on to the domain, and after making only two entries in my hosts, outlook, mapped file banks, etc. excellent work! However, here's my question...

  We use VNC widely remotely manage to help control our machines 100 + on our network. Our network is a network of class 10.25.1.XXX, and yet the VM is given an address 192.XXX.XXX.XXX in NAT mode.

  If I want to leave the running virtual machine and connect from work, I can't do my type in the 192.XXX.XXX.XXX as address/subnet is not in our routing tables.

  I'm not a network administrator, just the humble CEO of my company. Am I missing something?

  Thank you...

  Mr. bubbles

  I can't give advice on how get VNC running through a NAT configuration, but another option would be to give your virtual machine a network connected by a bridge instead of NAT configuration.  Then your VM would have its own IP on your network of 10.25.1.x.

• Serial Port is configured for a virtual machine...

  Dear team,

  I found the serial port is configured on one of the virtual machine, which follows is the blink of an eye the same.

  

  Just want, serial port is required for the devices on which?

  Usually, you see the serial port after a P2V and not detached from the VM.

  Why is it necessary?  Nowadays it probably isn't, but there are days where we still used modems on (among other things) serial ports.  Introducing a serial port to the virtual machine, you can go through the device that was attached to the serial port of the server host directly on the virtual computer.

  Today it is not really useful and you can probably just close the virtual machine and remove it.

• Network sharing between two virtual machines to XP

  Looks like it should be easy, but for some reason I can't make it work.  MacPro with two XP virtual machines running.  I want to share some files between virtual machines.  I tried to put them both in Bridge mode, but I was unable to ping each other.

  Is there anything else I need to do?

  I'm not too familiar with sygate.  As you have discovered, yes Windows Firewall allows for sharing of files across, but it disables ping responses (unless you enable it manually).  If you have Sygate running on one of these virtual machines, I would disable the windows one if you don't have multiple firewalls on the system for you in trouble...

  Open ports 135-139 (TCP and UDP) and also open 445 (TCP and UDP).

  Don't forget to assign points for correct or helpful answer.

• read the file of configuration for the virtual machine performance

  Hello

  is it possible to read a file from a virtual computer vmx when it is in use? The system is vSphere 5.5

  Regards Wolfgang

  Edit

  Please mention: I want to do with a vm running . The file is locked and I can't access it.

  Go to the copy and store the virtual computer is running in data and paste the .vmx into another folder. Then you should be able to download.

• Two virtual machines share the same physical network adapter

  I have a virtual network adapter that I linked to a physical network adapter on my box where two virtual machines are running.

  I assigned two virtual machines to this vmnet adapter.

  On one I can ping other machines of physics on the same subnet as the physical computer, but the other VM can ping only other virtual machines.

  When I try to ping from one physical computer to this virtual machine I get the error message windows "ping transmission has failed. General failure. ».

  Is what I'm trying to are not not possible?

  First thing to do is to ensure the automatic bypass is enabled disabled in the VMnet virtual network editor your use to the bridge to.

  Second need to see the output of ipconfig/all on the Windows host and guests and or ifconfig on the Linux host and or guests.

  DO NOT copy and paste the output directly in the body of the response rather redirect the output of the commands in a text file and then archive (compress) files in a single zip archive and attach it to an answer.

  You can use the following example:

  Under Windows:

  ipconfig/all > "% USERPROFILE%\Desktop\host_ipconfig.txt".

  ipconfig/all > "%USERPROFILE%\Desktop\guest (n) _ipconfig.txt".

  Linux:

  ifconfig > ~/Desktop/host_ipconfig.txt

  ifconfig > ~/Desktop/guest (n) _ipconfig.txt

  Also include in the archive .zip .vmx and vmware*.log for two Virtual Machines configuration files.

• Can join a Cluster of storage disk out of Maintenance DTS Mode to set up the profiles for a virtual machine storage policies?...

  Can join a Cluster of storage disk out of Maintenance DTS Mode to set up the profiles for a virtual machine storage policies?...

  
  IE can you define the rules of affinity DTS depending on how the rules of storage of profiles are configured for a virtual machine?

  In my mind it seems there is disconnect from the DTS and storage profiles.

  Thank you.

  = NOTE =.

  My lab at home, 2 organizes running ESXi 5.0

  Dv01 has

  Of startup vmfs 7200 RPM 160 G = dv01-BOOT

  Vmfs 1 TB 7200 RPM = VM02-VMFS

  VM02 has

  Of startup vmfs 7200 RPM 160 G = VM02-BOOT

  Vmfs 1 TB 7200 RPM = VM02-VMFS

  Vmfs 5900 RPM 2 TB = VM02-TV01

  I have (3) facility profiles of storage using 'User-defined storage Capablity' as shown below:

  (160 @ 7200 RPM SATA) boot > Boot

  Fast (160 7200 RPM SATA and 1 TB @ 7200 RPM SATA) > fast

  Slow (2 TB @ 5900 RPM SATA) > slow

  Then, I set up a storage Cluster with my local disks on dv01 (only to date)

  LocalVM disc dv01-BOOT and dv01-VMFS disk of the 'cluster of storage.

  I have a computer virtual called DC01 (HardDisk1) want to live on 'Boot' profile storage drive
  His "Non-compliant" poster according to the storage profile, it should run on drive 'boot' on dv01

  To get to this point, I put the StorageCluster in Mode of Maintenace 'DTS' and forced a sVmotion of all virtual machines off dv01-BOOT

  No disks are IO or claim of space.

  But once I take the 'DTS Maintenacne mode' STARTUP dv01 floppy is now get the DTS to return him to satisfy the storage profile (rule) I install... IE do the 'storage profile' VM complient (without doing a few externall API, the PS script or the 3rd party software calls)... ??

  Seems weird it is (or may be) such disconnection of a memory of the profiles and the StorageClusters and the DTS?

  Thank you...

  At this point, I think that storage DRS and storage profiles are two technologies to separate and work independently, but what you suggest is a great idea-

• How to create disk shared across virtual machines on different hosts

  Hello

  We implement Oracle RAC on two virtual machines, one on each of the two armies for redundancy. For our installation:

  • The two ESXi hosts two SAN access a logical unit number.
  • Two virtual machines on the hosts must have access to a single virtual disk on this LUN (or unit number logic itself) at the same time.

  We tried the following:

  • Creation of a data store associated with the LUN, and then creating a new hard drive on each virtual machine using the same virtual disk on the data store. This operation failed because as soon as a virtual computer runs, the other virtual computer cannot run since the first has a lock on the file from the disk.
  • Creation of a new hard drive on the virtual machine through RDM. This operation failed because only the first virtual machine has this option of disc. Once the ROW has been assigned to the LUN, the other virtual computer cannot create its own RDM for the LUN.

  I'm learning just VMware so I can miss a fundamental method to accomplish this, or perhaps, it is not possible at all. You know a way to create the installer I described?

  Welcome to the community,

  I can not specifically help with the Oracle RAC, however, I would recommend that you take a look at MSCS documentation for how to configure shared disks. There is a difference in the way in which you have installed the VM, for example all VMs on an ESXi host or on different hosts. Please keep in mind that MSCS is a cluster without sharing, which means that only one node at a time has access to a shared virtual disc/RDM.

• Two virtual machines running on a same PC network

  Hi all:

  I'm running both SUSE Linux Virtual Machines (VM) with VMPlayer on a PC with Windows server 2008. The two virtual machines are configured to the bridge at the same host physical ethernet port (bridge mode). Started the first virtual machine can access the network without problem, but the second VM started not. The order from VM has been changed in order to check if it was a configuration problem on one of the virtual machine, but according to the virtual machine that is launched in the first place seems if appropriate switch VMnet0 and block access to the second VM. Defined for each virtual computer LANs are different: 10.2.1.0/24 for a VM and 10.4.1.0/24 for the other.

  Any help will be really appreciated

  Case resolved, I realize that he had a message waiting in the toolbar of VMware by saying * adapter Ethernet0 do not have network connectivity. MAC 00 address: 0C: 29:58:61:19 adapter Ethernet0 is located between reserved address or is being used by another virtual card on your system. *. I just checked on google and found an identical case on the VMware communities with the solution: http://communities.vmware.com/thread/269465?start=0&tstart=0. To make the story short my VMs have been duplicated and used the same MAC address. So just stop a virtual machine and generate a new MAC for him in settings-> settings-> Advance-> ECS

• VCenter shows a network for a virtual machine that is not associated with any host

  I have a win2k3 VM who at one point had a network assigned to him called "MONITORING".  This network is configured is no longer in the ESXi (5.5) environment.  The virtual machine is connected to a network called "PRD-SURVEILLANCE" which is correct.  It's not really cause a problem, but I can't find a way to get rid of the object of MONITORING network.

  In VCenter MONITORING networks has a VM of 1 meter, the number of hosts of 0.  I also see it in the VM - dialog box, change the settings, but there is no option to remove it.  Profile Image to the virtual machine is version 10 so I can't use the old Client of VI to try to remove it.  I have checked each host and do not see this listed network object.

  I tried to restart the VM, it migration between hosts, changing its network of SURVEILLANCE of PRD to another network and vice versa and close - remove NIC and add a new card network.  MONITORING legacy network still appears in the config.

  For the virtual machine's .vmx file shows that the correct network: ethernet0.networkName = 'RDP-ANALYSIS '.

  Any suggestions on how I can remove the artifact of MONITORING network?

  The virtual machine has a preview that was created at the time where the MONITORING network was still affected?

• How to configure the CD driver on the host for a virtual machine?

  After you create a virture machine and put the CD of driver on host, when powered on the vertual machine, may not start the drive form the CD only from NIC.

  How to configure the CD driver on the host for a virtual machine?

  Right-click on the virtual computer and go to edit settings. Click the Options tab and under the tip list, there should be Boot Options. Enter an amount of milliseconds to wait before your boot, so you can activate the CD-ROM. You can also activate the CD even if it boots to the NETWORK card option, and then reset the virtual machine. Get the focus of this virtual machine on the console session, and then press ctrl-alt-insert. Your CD-ROM will stay connected if you do not want to delay the startup process.
