LUNS shared between virtual machines? How?

• vCenter storage iSCSI 5.5 and shared between virtual machines

  I have just two 2012 Win computers virtual server in the cluster.  I've prested my iSCSI LUNS and the ESX host can see them and I might add in order to become a data store.

  My VMs Win2012 need to share the storage for a cluster SQL database.  I have never done this and everything I tried at this point has failed.  I tried to create the ROW, but that only worked to connect it to a player on one of the virtual machines.

  I'm sure this is possible, but I'm not even sure where to look.  Is it really that RDM is for or is there another way?  Looks like I have would be sufficient to use the initator iSCSI in Windows to connect to my SAN but that would probably slow.

  Any help would be great!

  Yes it can be done - have you seen http://pubs.vmware.com/vsphere-55/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-55-setup-mscs.pdf

• No ping between virtual machines

  Hello

  I use VMWARE 7 program... I installed two virtual machines (windows server 2008 and windows 7)... I have attached two pic for each other... .my problem is... There is no rattling between these two machines... I disabled the firewall in both entities... How you can help me in this...

  My respects

  Post edited by: a.p. - changed the subject of the "Greetings" to "no ping between virtual machines.

  I do a bit of practice for MCITP study... In windows server 2008, I use Bridge and in the Windows NAT using 07:00

  Well, I guess you should start your trip MCITP become familiar with the IP configuration and routing

  Addresses that you configured do not work that way. Assuming that the physical - bridged - network (if connected) is 192.168.100.x, you may be able to access the Windows Server 2008, but you will never be able to access the virtual from Windows 7 computer with the NAT configuration, because NAT is running on another network (vmnet8 - 192.168.201.x). Depending on the need or not to be able to access the outside world of the virtual machine, you should consider is instituted two virtual machines with an IP address in the range of vmnet1 (Host-Only - 192.168.80.x) or vmnet8 (NAT - 192.168.201.x). In the case of NAT, configure the virtual machine for DHCP or use IP addresses between x.x.x.3 and x.x.x.127.

• Disable copying files between virtual machines

  When I go to several virtual desktops using VMware View 4, I am able to copy files between virtual machines. Virtual machines are located in various isolated networks. It is a security problem in my organization and how do I disable this feature? I am not able to find any related configuration in sight connection to the server. Thank you!

  I assume you are using RDP as the Protocol currently, correct?

  In this case, you will need to implement some GPO:s in the workstations to avoid copy and paste.

  Look in the 'Extras' folder on the view connection server, there are a number of ADM files that you can implement to restrict all sorts of things.

• flow of traffic between virtual machines

  If I had 2 machines virtual on the same slide in a M3 of b200 on the same vswitch, is communication on traffic between the 2 vms strictly inside the m3 Server?

  What if I had a virtual machines on a b200m3 and another virtual machine to another b200m3?

  same chassis and the chassis is connected to the FI

  Traffic between virtual machines will stay on the FI or it will mount the switch to basic?

  so, if is blade1 VM1 and VM2 is Blade2 and both on the same vlan
  Traffic will remain within FI or it will go up North to core?

  Both is possible! as I said above: If the entry and exit are on the fabric a RESP. B, it is switched.

  However, it could also be A penetration, exit on B or vice versa and then must go to the North (and get switched L2)

  What if

  Blade1 is VM1 and VM2 is on blade2 but on different VLANS, the traffic will have to hit the correct base gateway?

  Yes!

• Networking between virtual machines on different hosts

  Hello

  I need some advice on the basic approach to networking between virtual machines, each running on a different host machine.

  Consider the following configuration:

  I have a few processes that are running in a Machine virtual Ubuntu. Call this guest1.  I guest1 race inside a real computer running Windows XP SP3 and VMware Workstation 7.x; Call this host 1.

  I have a copy of this virtual machine that I put on another machine.  Call this Guest2.  I have Guest2 running on a separate physical computer, also runs Windows XP SP3 and VMware Workstation 7.x; Call this host 2.

  Now, I would like to guest1 and 2 comments to make networking with eachother.  I wish they were able to ping, SSH, etc., among others.

  This is where I am stuck. I tried setting the virtual machines to use the bridged network mode.  I tried to connect my router on each computer and manually assigning IP addresses to each host and each virtual computer.  When I do this, guest1 can Host1 and Host2 ping, but cannot ping Guest2 and vice versa.

  What is the right way to do this kind of network?  This seems like an obvious application, if you want to perform simulations on multiple virtual machines residing on different computers on the network.

  I apologize if this is the answer elsewhere, I had to dig and was not able to find the solution.

  Thanks in advance!

  Guests must be on the same subnet, like 'real' hardware machines.

  1 when you copied the VM and then started, what did answer you the question of copy/move? (this determines if a new MAC address is applied)

  2 view each guest and ' ipconfig/all' results 'ifconfig - a' by the hosts.

• connect several LUN to a virtual machine

  Hi all

  I was wondering is it possible to connect multiple LUNS to a Linux VM? We want to store data from different departments in separate LUN. Any suggestions are appreciated.

  Thank you

  Ke

  Hello.

  Yes, you can present several as RDM LUN to a virtual machine.  I have a Windows file server built exactly as you described, using the same approach.

  Good luck!

• 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.

• Shared LUNS / models between virtual centres

  I'm looking to create a LUN to hold our models and would like to share on all of our servers.  We currently lack separate virtual centers of production and development for models would be shared between the two.  No problem with that?

  No problems.

  The only requirement is that the model storage is shared between the ESX (or at least ESX on which you will deploy your model).

• How to configure NTP between Virtual Machines without using Vsphere Client

  I have a group of 8 virtual servers of 5.5 ESXi without an Internet connection. There are virtual machines on each of these 8 virtual servers.

  I did one of these 5.5 virtual ESXi host a NTP server by editing the file /etc/ntp.conf with below configuration and

  started the ntpd daemon. He began to take the time to its local clock, here's the output of ntpq Pei

  IP server 10.108.190.14

  ip address of the client 10.108.190.15

  Server /etc/ntp.conf

  > > driftfile/var/lib/ntp/drift

  > > server 127.127.1.0 maxpoll 4

  > > fondant 127.127.1.0 stratum 10

  | ==============================================================
  | * LOCAL (0). LIUX. 10 l 2 64 377 0.000 0.000 0.001

  Then I edited the file /etc/ntp.conf on customers with below configuration but the customer would not synchronize with the server. He

  wouldn t get response from the server. Here is the output of ntpq Pei

  Customer /etc/ntp.conf

  > > driftfile/var/lib/ntp/drift

  | ntpq Pei

  |      refid distance st t when poll reach delay offset jitter

  | 10.108.190.14 INIT. 16 u

  Now, when I configure NPT Client/Server on virtual machines through the Configuration Option under Option Configuration time

  in Vsphere Client everything works fine and the client and the server to synchronize with each other. I checked the file /etc/ntp.conf on both the client

  and the server and it has a couple of restrict 127.0.0.1 and restrict the lines added by default kod nomodify etc.

  So why NPT Server featured when enabled via Vsphere Client works very well, but it does not work when it is configured manually

  in the virtual servers directly.

  I was connected to a vCenter Server Appliance through the VSphere Client and enabled the synchronization of time of the NPT.

  I really need to know how to configure the NTP server without using the Vsphere Client so that I can automate the

  task by writing a python script that would connect to each virtual server and NTP Client/Server configuration.

  Any help in this issue deeply appreciated!

  Thank you!

  You can configure the ntp server without using viclient.

• How to configure rdm to use iscsi lun in a virtual machine using ms iscsi initiator?

  I have equallogic SAN attached to a cisco 3750

  switch. It comes to our storage network.

  Within the virtual machine for all readers of data other than my c:\ that has the operating system I would use iscsi data switch that has 4 network ports on four different nic cards already assigned.

  According to what I read a virtual machine can use only 4 nic so I have a Production network the other three that I would

  Use it for iSCSI data.

  Three ports of each virtual computer network for using ms iscsi with MPIO

  initiator.

  I have already attached the RDM using esxi 3.5 as a physical mapping of RDM.

  My question is how to configure the ports of the network adapter in the virtual machine?

  The VM network is on 172.19.2. * where iscsi is on 172.19.21. *.

  What would be the entrance on the network adapters in the virtual machine that is running ms win 2 k 3 r2 x 64.

  Thank you.

• How see Horizon share the GPU between virtual machines?

  Say I have three hosts, and only two have the GPU Nvidia, what happens when I vmotion virtual machine to the host without GPU?  Only VM loses the ability to use the GPU?

  The short answer is Yes (hardware GPU).

  If you have the "3D renderer" option in the game of pool parameters seen on 'Automatic' virtual machine will always be able to power on, but it will use a GPU rendering software (not hardware as your other hosts with an installed GPU).  If the '3D renderer' setting is 'Material' the VM does not power on when you try to run out of the host with no GPU and I think he can not even vmotion over the host with no GPU installed (there should be a check to ensure if the virtual machine is compatible with the host his tent of vmotion for).

  Kind regards

• Sharing of virtual machines and the NETWORK adapter settings

  I usually have multiple NICs per physical machine, and I often map more than one NETWORK card in a virtual machine. This does all work well with 'regular' virtual machines and virtual network Editor. I use 10.0.1 on linux 64-bit Workstation.

  As soon as I share a virtual machine, the NIC mappings cannot be changed in any useful way. I can spend only NAT, HostOnly and connected by a bridge in a ComboBox control, without the ability to select a specific vmnet. Although connections are bridged, they are displayed as NAT, which makes no sense at all...

  What is the reason for this? I'm doing something wrong? If this is the intended behavior, it's shared VMs useless for me...

  Kind regards

  Thomas

  I reinstalled VMware Workstation and now I understand what happened.

  I need ever - and HostOnly-setting in NAT network, so the first thing I usually do after installing VMware is to remove them and fills vmnet0 to eth0 and eth1 to vmnet1. This works perfectly well with non-shared virtual machines.

  For shared virtual computers, this mapping has been messed up somehow. Now it seems to work fine, I removed all the vmnets and has created vmnet10-> eth0 and vmnet11-> eth1.

  If the problem is solved for me; but I can't say how the maps I screwed up. I certainly had two bridged devices, but has been shown only a single bridged device.
