• Card reader chip as a pass through for VMware View 5.1 device (NOT USED for AUTHENTICATION)

  I try to get a USB Smart Card Reader * to work on related under VMware View 5.1 clones

  * not as an authentication device, just like a transmission of smart card reader

  Not tried:

  1 activated pass through card reader in the registry for the VMware view client

  2. active "allow redirection of card reader" in the policy active directory

  3. customer connected to view, selected USB drive list, connected to the customer

  After that, the card reader will appear with a "generic smart card", but it does not actually work.

  We executed the diagnosis of the smart card and he pointed out that the drivers are ok and windows service is ok, but the map can not be found.

  PS: When we tried first, about 2 weeks ago it worked, but it has suddenly stopped working. (Needless to say that the virtual machines and the Clients were restarted several times).

  Check that you have not installed the "PCoIP smart card Redirection" option during the installation of the agent. If it is present, it will redirect calls made RDP client smart card. Because you use a 'local' to the desktop USB drive, you don't want to do.

• Tool to display the configuration of VMware ESX in a human readable form

  Hello

  I'm looking for a tool to display our configuration of our vSphere hosts.

  Is there a tool available (perhaps thirdparty)?

  Kind regards

• VMware ESX server update CD & 3WARE CONTROLLER

  VMware has a cd ISO labled the following: VMware ESX Server 3.5 Update 3 driver for 3ware 9650SE and 9690SA SAS HBA controllers GCCA CD.  The URL is: http://www.vmware.com/support/vi3/doc/drivercd/esx350-3w-9xxx-2.24.08.021vm35-146309.html#InstallESX

  QUESTION: Anyone know if this drive works with ESXi 3.5?  The downloads of the installation, update 3 or 4, I tried to load do not work for me.  If this does not work, can you me where the download is that he asks?  If this is not the case, the ISO EXSi can be modified to work.

  The disc is for ESX only but if necessary you can extract the driver and use with ESXi.   I had check ESXi was last updated yesterday and there is no 3ware with her driver.   See the instructions here to create an oem.tgz file - http://www.vm-help.com/esx/esx3i/customize_oem_tgz.php.  There is also a link to the 3Ware Update1/2 site of 3Ware driver.  I check which driver is more recent and use it.

• VMware ESX 3.5 and disabling carrots

  Hi all

  We have a Cluster ESX from VMware ESX 3.5 U3 that was built for a specific product that has a licensing model that doesn't fit well with the virtual server running model.

  The basis of this cluster is 3 x BL465c G1 Dual Core servers HP with 16 GB of memory each. We're going to run out of memory, and I can't add memory without add because of the architecture of AMD processors.

  Adding more CPU will have a big impact on licensing costs - once again not the licenses of VMware.

  I want to do is add a second processor DC and then use BIOS to disable half of the cores in each processor.  This will allow me to add an extra 16 GB memory per server and stay within the limits of the license.

  My question - has anyone with disabilities hearts on a host ESX from VMware, specifically after ESX has been installed. All that needs to be done?

  I tested the disabling function of carrots on a Windows Server and who did replace the drivers, I was wondering if VMware ESX should similar updates / management.

  Rob of TIA.

  You'll be fine, apart from the fact that, by adding the Jepp second you will need an additional CPU, per ESX host licensing doesn't mind.

• Network configuration of tolerance of fault on VMware ESX

  Hi, I need to implement of FT and wanted to learn about best practices. FT uses the VLAN VMotion, as well as a VLAN for registration of FT. VMware recommends separate NIC and subnets for VMotion and FT logging.

  The current practice in our implementation is to configure VMotion and the Console on vswitch0 Management Service using 2 NICs for example

  Network - Active Nic - Nic ensures

  Console - Nic0 - Nic1

  VMotion - Nic1 - Nic0

  I'm contemplating presenting a nic 3rd for the recording of FT, using the following settings.

  Network - Active network card - ensure Nic

  Console - Nic0 - Nic1 & Nic2

  VMotion - Nic1 - Nic0 & Nic2

  Logging FT - Nic2 - Nic0 & Nic1

  Do you have any views on the above? This is consistent with best practices?

  In addition, VMware recommends 10 GB nic for FT Logging also, but is acceptable as a minimum 1 GB standard?

  Thank you

  For the implementation of FT, you must use dedicated NIC. I would not recommend configuring Active / standby that you planned. Rather, use NICs for the logging of FT.

  If not already done so, take a look at http://www.vmware.com/files/pdf/perf-vsphere-fault_tolerance.pdf

  ... Cards separate and dedicated network is recommended for traffic logging FT...

  Hi - I ended up having to do such things in the past as well. I just built a virtual machine added lots of processors and memory, then for the CPU, I used the script CPUBusy.vbs from VMware (Google search which) and down it load times so that he began to max real physical processors... For memory, I just opened a massive text file in Wordpad and scroll up and down it. This gave me the circumstances to test the alarms, just don't do as a busy time or use some dev ESX servers...

• IPSec on VMWare ESX 5.1 communication problems

  Hello

  We have 2 computer systems.  You running us VMWare ESX 5.1 and the other is running Ubuntu 14.04.  We have problems for IPSec to work between the two systems.  We cannot find any documentation or known issues with IPsec on VMWare ESX 5.1, so we're going to reach out to the community.

  Here's what we did:

  1. we configured Ubuntu and VMWare systems to use IPv6, we can ping each other using IPv6.

  2. we configure IPSec on an Ubuntu operating system by following the instructions below:

  https://help.Ubuntu.com/community/IPSecHowTo

  3. we have followed the instructions below to configure IPsec on VMWare.

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1021769

  Here's the problem:

  When 2 Ubuntu systems run IPsec, they are able to ping each other.  However, when allow us IPSec communications between VMWare and Ubuntu, the ping is suspended.

  Here is the result of the configuration of command esxcli on VMWare:

  UBUNTU. IPv6.ADDRESS-> Ubuntu IPv6 address

  VMWARE. IPv6.ADDRESS-> address IPv6 from VMWARE

  
  Name Source address Destination address State SPI Mode Encryption Algorithm, integrity algorithm to life

  GoToDPSP UBUNTU. IPv6.ADDRESS/64 0 VMWARE. IPv6.ADDRESS/64 0 in ipsec transport GoToDPSA

  Here's what we found:

  After debugging the problem (using tcpdump), we found that the VMWare system sends the ESP packets, but never sends a package AH (required for IPSec authentication).  Even when the encryption protocol is null, the system of VMWare would always send ESP packets, but never once sent a package of AH.

  Here is the resulting execution trace: Ubuntu - ping-> VMWare:

  ...

  IP6 UBUNTU. IPv6.ADDRESS > VMWARE. IPv6.ADDRESS: AH(spi = 0 x 00000256, seq = 0 x 16): ICMP6, an echo request, seq 1, length 64

  IP6 VMWARE. IPv6.ADDRESS > UBUNTU. IPv6.ADDRESS: ESP(spi = 0 x 00000300, seq = 0 x 3), length 160

  Summary:

  There seems to be a problem with IPSec in VMWare ESX 5.1 on IPv6.

  We noticed that the downloads section of the site support provided patches for VMWare ESx 4.x and earlier, but lack of patches for VMWare ESx 5.x.

  Are there known issues in this area or available patches to fix this problem?  Your kind suggestions would be greatly appreciated.  Thank you.

  Sorry for the late reply, but here the analysis of what is happening and why you are experiencing a problem.

  The Encapsulating Security Payload (ESP) to IPsec protocol will encrypt a payload of the packet and can

  Optionally authenticate the packages as well. You do not include orders allowing you to set the

  Security Association (SA) and political security (PS), but the output in your post indicates that you

  you want to encrypt the payloads both authenticate packets in mode of transport between the hosts.

  I don't know why the Ubuntu IPsec HowTo examples using protocols AH and ESP to encrypt and

  authenticate the packets. In our view, it is best done in a single step with ESP, ESXi only

  offer the option of AH with IPsec. Of course, this requires configuring the ESXi server and your

  The host with a configuration of IPsec compatible Ubuntu (or any other operating system).

  To illustrate, suppose the ESXi server has the address 2001:db8:1 and the host of Ubuntu has the

  address 2001:db8:2. We will use cbc-3des for encryption of the useful and hmac-sha2-256 load for integrity

  authentication mode of transport - just like in your message.

  On the ESXi host, the commands to do this might look like this (of course, you need to generate your)

  own keys and not re-use those I did).

  Hello

  1. what happens with the DRS to deploy new virtual machines with Virtual Hardware 7?

  2. they will receive only on ESX 4.0u2 hosts?

  3 could cause instability on the other virtual machines?

  1 VM' with HW v7 will be migrated only between vSphere 4.X nodes in a cluster

  2 VM with HW v7 will be only on vSphere 4.x nodes

  3 nope

  1. I raise this because I have no experience in mixed environments, and I expect the DRS feature so smart that moves and power on virtual machines on hosts that are able to manage virtual machines with virtual hardware that is compatible with, I'm so innocent?

  2. the virtual machines with Virtual Hardware 4 can be moved throughout these clusters 3.5 or 4.0, but what happens with VM with the newest virtual hardware?

  The only thing to look at will be the VLANs that you got set up on the vSwitch. You have defined VLAN native example, the VLAN untagged on the switch to be 4094, any traffic sent on the aura tags trunk VLAN, which will be removed by the vSwitch.

  In my setup, I have established groups of ports using VLANS and VLAN 2 10. Traffic to the virtual machines on these VLANs are .1Q marked by the physical switch, which is then stripped by the vSwitch.

  Take a look at the section "VLAN in VMware Infrastructure" on page 7 the concepts of virtual networking André already mentioned, but also the other interesting reading material is http://www.vmware.com/pdf/esx3_vlan_wp.pdf.

  Finally, for the side of the switch of things, look at the examples on Scott Lowe's blog at http://blog.scottlowe.org/2006/12/04/esx-server-nic-teaming-and-vlan-trunking/.

  Concerning

• several doubts with vmware esx 3.5

  guys, I had many doubts on VMware ESX. can you please answer me if you know the answers to any of the sub questions

  In the meantime thanks for all those who respond to my questions.

  (1) how to install ESX on the SAN to start on the SAN?

  (2) how to back up the database to the virtual Center Server? is it something that supports a SQL DBA or do we do as a VMware administrator?

  (3) for the installation of VCenter server, its request for the installation of the apache tomcat server. Why is this? It is with ESX 3.5

  (4) do we need a separate license for VCenter server apart from the licenses that we buy for the ESX servers?

  (5) if 2 virtual machine port groups are on two different VLANS, to send it, we need to configure a vyatta router. How can we do that if we are not a guy from Cisco?

  (6) we give only the IP numbers for a console Service and Vmkernals but not the virtual machine port groups. If so, how these virtual machines on these virtual machine port groups know what are their IP numbers? If we want a static IP number for a virtual machine, we inside windows from a virtual computer configuration?

  (7) is the Virtual Machine power off a soft stop?

  (8) what happens when we make one pause a Virtual Machine? I think that there is no option in a machine physical windows original. so, what does this mean VM break?

  (9) how many vsphere client can simultaneously access the vcenter Server?

  (3) for the installation of VCenter server, its request for the installation of the apache tomcat server. Why is this? It is with ESX 3.5

  Don't know why VM Ware chose Tomcat, they SAY THEY is not secure... No matter what.  It's just another Web server and its an option that VM Ware has chosen to work with vCenter.  It's not good or bad, just different... many people THINK apache is better, it is a matter of opinion.

  (6) we give only the IP numbers for a console Service and Vmkernals but not the virtual machine port groups. If so, how these virtual machines on these virtual machine port groups know what are their IP numbers? If we want a static IP number for a virtual machine, we inside windows from a virtual computer configuration?

  It is a way, you will realize quickly that will be a major pain.  I do like DHCP, reserve of the INVESTIGATION period.  Unless you know a way to connect to hundreds of virtual machines and change their IP remotely, this is probably the simplest method.  Unless you like make manual updates... then knock you out.

  (7) is the Virtual Machine power off a soft stop?

  Not as the name suggests it is a POWER-off.  Comments stop is a soft stop.

  (8) what happens when we make one pause a Virtual Machine? I think that there is no option in a machine physical windows original. so, what does this mean VM break?

  Confusion in the name.  It simply means 'suspend' and there is an option on physical machines... probably no servers, in the form of profiles of power are generally disabled, but it IS possible.

  (9) how many vsphere client can simultaneously access the vcenter Server?

  no theoretical limit... or I do not think that someone took the time to discover.  You will grow up to the moment where you have too many users connected to vCenter vCenter anyway... So the connections will not be reached.

• ESX 3.5 will recognize additional HDs on PowerEdge 2900 (is not a member of a RAID 1 configuration)?

  Hello gurus/VM-masters

  I am still a novice in the VM world: 3

  The installation program:

  Dell PowerEdge 2900 running VMware ESX Server 3i 3.5.0 build-153875

  Installation of two hard disks in RAID 1

  Only one store of data in RAID1

  The question:

  I have an extra hard drive that I want to add. http://Cheetah 15K.6, SAS (Serial Attached SCSI)

  I was wondering if there where it is possible to add additional hard drive and create a new data store to add new virtual machines on it?

  ESX will recognize it as additional storage?

  Is it bad/mess with existing RAID1 configuration?

  Or is it simple, plug-in HD

  Thank you!

  RAID 0 - a definition of tolerance drive no fault, in this case a single PIN.

  Many raid controllers able technical force you to set the drive as a feature available on the controller, before the operating system can see it, in this case a drive would give a raid 0 LUN set on the controller.

  Your controller will accept it is submitted or you need to take the material down to set it. Sometimes, this feature is available via an interface ILOM (Integrated Light Out Manager) of the server allowing the definition without an outtage.
