• Flight hover text on my site by default, ignoring my HTML mouseover. Two different hosts show the same bug. (Chrome showed same on one host.)

  My hover/mouseover stylesheet correctly texts show when < my custom > .css is local disk (offline), but when online, a default value "CTRL + R improves the quality of this image...". "watch instead, presumably from the browser.

• Why is no longer a faster network between two different hosts?

  Hello community!

  I need help in this mystery.

  I have three computers different virtual, all of them with e1000 (also I tried all VMs with vmxnet3) and the latest vmware tools.

  Two of this mV, are in the same physical host (ESXi 5.5.0 2068190). Call for example: VM - 1A & VM - 2A

  Another virtual machine, is in another physical host (ESXi 5.5.0 2068190). Call VM-1 b

  Both ESXi hosts are connected with two cards 10 Gbit network with load Balancing: "From hash IP route" and detection: "link status only.

  Traffic Shaping is disabled in all Ports.

  The environment is very clean, and we have more VMs that can disrupt the test (or inappreciable).

  VM - 1a: 10.12.50.201 - physical host ESX - A

  VM - 2A: 10.12.50.202 - physical host ESX - A

  VM-1 b: 10.12.50.200 - physical host ESX - B

  Why I don't see better network speed reference, when two virtual machines send something two physical host is different than when the two virtual machines are in the same physical host?

  It is not a question of "iperf", I used the other test with CPS and I had the same speed.

  Thank you very much!!!

  PS: The physical host computers are: Dell PowerEdge r.620 - 16-core Xeon - 384GB RAM

  

  Have you tried to move your VM on different hosts to the same host?

  Your names of:

  VM - 1 a host has

  -VM-1 b on Hots B

  ToDo

  Now move VM-1B for A Host and repeat the test (two virtual machines on the same host). What happens now to the speed?

  Check

  -How is the CPU usage during the test we Host-A, if you have 2 virtual machines on this host?

  -What is your ratio of P2V CPU? (overprovisioning?)

  What it could be

  -Host doesn't have enough CPU power to serve the two virtual machines (or over-provision P2V related problem). But for me no sense if I see your config server with 16cores.

  -It is not a host but a related problem of VM (perhaps it depends on the VM - A2). Makes the most sense for me (your test is to check)

• MSSQL server VM cluster should be in the same host or different hosts with RDM

  Could someone me on how to place the code SQL cluster s VM with RDMs in ESXi hosts for advice.

  What is the best practice to place the SQL VM s in ESXi hosts.

  Affinity or an anti-affinite...?

  Appreciated your valuable answers.

  Depends entirely on the use case.

  • 2 MS SQL nodes on the same host to see the availability of the software
  • 2 nodes on different hosts to see the availability of the equipment

  I'd say MS Clusters on the same host (at the time of HA and vSMP FT) are redundant VMware features and represent an increase in management fees. The MS cluster on hosts provide something in addition to what VMware vSphere alone can provide!

• segregation of VM on different hosts

  
  I'm new to vmware releatively, but I am interested in the design of fault tolerance and what are the specific virtual servers that ensure on different hosts. For example in small installations if you had 2 DCs on a single host then who is it a single point of failure in the AD services? Outside of DC, what other specific types of servers/server roles warrant you are on different hosts? Or with VMWARE HA do you not need to worry as much as if his is attached to a cluster virtual machine must be picked up by another host if the host fails, so segregation is not so much a concern?

  Hey cb122,

  Welcome to the community and Vmware,

  First good HA is very different then FT.  HA leans on the hosts and makes sure that all your cluster hosts are running and the computer virtual is running.  If a host fails HA reviews cela and turns on all the VMS running on the host failed on another host in the cluster.  Your VM will see this as an unexpected shutdown.  Although short, this may take a few minutes for all your VMS is to start again based on what was running on the failed host.

  Fault tolerance is basically HA on stariods and what it does is eliminate this short stop breakdown or unexecpted on the host failure.  But that comes at a high cost, reduced capacity, there are a number of requirements to work ect ect, look under FT for more information.  FT back more now is your only allowed to have 1vCPU IP protected VM, which kind of shoot it in the foot because most systems requiring such high availability require more vCPU.   However how FT works in summary is this: you select FT on a virtual machine, and then creates a snapshot of the virtual machine and it works on a different host.  Any changes made to the virtual machine are always synchronized lived with his shot.  If the failure of a host that is running your VM, the VM snapshot is then invited to production and immediately resumed all of its features, it generates on an another snapshot on another host in the cluster to its protection.

  Awenser your question each environment is different, but most of the time a cluster of 3 + host Vmware will protect you for most, but in your case I would put a rule of DRS in to divide your virtual DC 2 as if both are on the same host and that host fails, you will lose all AD and probably DNS as most people run these 2 services together.  This could be problmatic to your environment.

  Aside from that, I would be just shared any VM that could not handle all seen down at the same time, if a failure of the host.  A good example of this would be a web server farm.  Say, you have 4 IIS servers in a web farm, you do not want to run all 4 on the single host as if that host fails your website goes down for 2 to 4 minutes until these web servers would start up on a new host.  In this case, you could create a ruleset DRS to keep 2 webservers on a host and 2 on the other.

  I hope this helps.

• 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.

• Migrating Forms 10g GR 11, 2 different host

  Hi all

  I'm Migrating Forms 10 g to 11 GR 2. I read a document for upgrading forms 10g to 11 GR 2, but there is no comment about the different host upgrade.

  Also, there is only one way for the upgrade. Who is using "upgrade wizard".

  Currently, here is my situation.

  1. I use forms 10g now on the server A.
  2. I installed 11 GR 2 forms on server B. It works well.
  3. There are a few files of forms compiled on ServerA.
  4. I want to migrate these forms and the configuration files in the server A to Server B.

  If I can't use "upgrade wizard", I just copy the configuration files two server (formsweb.cfg and default.env) and paste the B server configuration files. But I think that it is not good idea to migrate.

  Is there something else easy way and security for the upgrade.

  Please answer to me thanks!

  Let me start with the urgent comment: do NOT copy the configuration of earlier versions and drop them in the new environment. It's a bad idea for many reasons.  The most obvious is because new version has new settings and changes, some of which are required.

  I hope that, in your environment to version 10 you does not alter the [default] section of formsweb.cfg.  If this is the case, then you can easily copy your sections in the file of the new version.  However, before you do anything like that, make sure that you stop the Server Admin v11 and Managed Server (WLS_FORMS).  Don't try to do it with them running or your changes likely will have lost to ignored.  The default.env should be similar.  You can replace the one-for-one entries, but do not replace the entries found in the file.  Thus, for example, you can copy your old FORMS_PATH and drop it into the new file.  Comment out the existing and use your instead.  And so on.

  OK, we can all calm down now.

  The next thing to address is this statement "...". compiled form files on server A... ».  You can also copy forms of update modules / generated from one version to the other.  You need to rebuild 'X' (fmx, mmx, plx) of files in the new environment, using the new compiler.

  As for using the upgrade wizard, there are some limitations to use, needing to be on the same machine.  However, despite everything, my recommendation is that not use you it anyway.  In most cases, you will have more success and much easier to maintain the environment if you do things manually.  AU is especially useful when you have significant customizations and complex throughout the battery (SST, Web Cache, forms, reports, etc.).  For typical configuration changes, manually create the new that's going to be the way to go.  It will give you also a chance to clean by removing changes made previously which are no longer needed.

• 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.

• Changes of MAC ADDR comments during playback on different hosts

  Is it possible to assign a STATIC MAC ADDRESS when you play guests on different hosts?  We have two physical machines that play three different GUESTS and ADR MAC must not change between them it is used for firewall/internet security.  I tried to use the following, but it seems that the config has been changed after the virtual machine has been launched:

  ethernet0. AddressType = 'static '.

  ethernet0. Address = 00:50:56:XX:YY:ZZ

  CHANGED TO:

  ethernet0. AddressType = 'generated '.

  ethernet0.generatedAddress = "00: 0C: 29:5 has: 7B: a6.

  East - this behaviour expected and the correct way to define STATIC MAC ADDR between different hosts?

  ... or just add uuid.action = 'keep' to the vmx file.

• Guest VM XP is aware that it is running on a different host

  I installed a minimum configuration of Windows XP and installed a program call pass4sure. I activated the pass4sure on the virtual machine. If I'm running the virtual machine to another host with the same hardware platform (Dell Dimension 3100 - VMware workstation 5.5.1) as the original host, fine.

  Then, I installed VMware workstation 5.5.1 on my Gateway laptop and copied the folder containing my VM to the laptop. When I run the software pass4sure he wants to be turned on because he thinks that it is running on a new machine.

  Anyone know why this is happening? What information is passed to the guest to make them aware that it is running on a different host?

  I kept the same uuid and MAC address when copying from the guest to the laptop.

  What is interesting is that the virtual machine works very well if it runs on a different Dell 3100.

  Workstation 5.5 has somewhat limited capabilities, but you can try the following options added to your config file:

  monitor_control.vt32 = "TRUE"
  
  cpuid.1.eax="0000:0000:0000:0000:0000:1111:0100:1000"
  cpuid.1.ebx="0000:0000:0000:0010:0000:1000:0000:0000"
  cpuid.1.ecx="0000:0000:0000:0000:0000:0000:0001:0101"
  cpuid.1.edx="0000:1111:1110:1011:1111:1011:1111:1111"
  
  cpuid.80000001.ecx="0000:0000:0000:0000:0000:0000:0000:0000"

  You try to share a virtual disk between two virtual machines using a SCSI reservation.

  VMware Server does not supports drive sharing between virtual machines sitting on different hosts (desktop & laptop).  You can't do that.

  Your two virtual machines need to be on the same host computer.
