• No Web hosting, but what about the media space for a Web site?

  My understanding is that iCloud doesn't support web hosting, in the sense that I can't use iCloud for a Web page.

  However, can I use my iCloud space to contain the media accessible by the URL?  For example, I'm currently an MP3 file that I can hear some people.  Can I store in a part of my iCloud space and send a URL to where they are stored in iCloud?  Even if there is no relevant web pages?

• ESX Multipathing change... What is the effect.

  Hello

  We have esx 3.5 for the moment and we expect change VCS code of our HP EVA from 3.x to 4.x, because we have this windows 2008 clustering Raw Device Mapings suport to the San.

  I know that currently the VCS code runs as active/passive for multiple access paths and new tracks from VCS 4.x as active/active. Anyone know if this is going to be a problem by changing to active/active with ESX 3.5

  Thank you

  ESX supports A/A and A / P so it will work.

  Kind regards

• What is the interval of time between the virtual machine Linux and ESXi host synchronization?

  I have ESX5.0 with a centos6 installed on this linux virtual machine.

  After the installation of vmware for Linux virtual machine tools, I activated the time synchronization between the virtual machine linux and ESXi host through vmware-toolbox-cmd.

  I wonder what is the interval of time between the virtual machine linux and ESXi host synchronization? If I quickly time OS system, when the OS system time will sync back to the ESXi host?

  According to http://www.vmware.com/files/pdf/techpaper/Timekeeping-In-VirtualMachines.pdf:

  By default, the demon checks the guest only once per minute operating system clock.

  However, depending on whether the guest is behind or in front of the result is different. So, please read the section "periodic synchronization" (at least) in the document mentioned above.

• 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

  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

  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).

• Adding more than one host ESX and the upgrade at the same time.  What is the order of preference of the operations here?

  We are budgeting for more licenses and hardware for 2014 and want to do immediately in January.  I am trying to decide what is the best order of operations for adding two vmware hosts additional to our current installation of vsphere and also upgrade our vsphere / esx 4.1 u3 for the latest and best.

  We have 3 Dell PowerEdge R710 running ESX 4.1 U3.  In this vmware cluster, there is a vcenter server 4.1 U3 virtual machine handle this.  The three servers are about 90% memory used so we add 2 additional servers.  Probably the Dell PowerEdge r.620 since we get up 2 in the space of a 710.  Storage is on a san EMC NX4 NFS which will become too but not yet, let's just deal with the vmware part.

  When adding additional r.620 2, should I install ESX 4.1 on them and join them to the existing cluster and THEN pass vcenter and each one esx?  I ask precisely because 90% of use on 3 current servers, I need 2 other servers to support the update operations take place.  They would be able to repel vmotioned vm while each host receives an upgrade at the same time.

  So which is the best way to go about adding of the hosts and the upgrade?  Would I add as 4.1, then they would be available as targets vmotion and so I have room to start the hosts one upgrade at a time?

  If I update vcenter to the latest version, it is comparable backwards and can manage the 4.1 hosts, but also hosts 5.x?  I guess version 5.5 is the last one I would get from VMWare?  It is right of ESXi, then, how is this ESX ESXi 5.5 4.1 upgrade?  How much storage space do I need for ESXi 5.5, as I'm dechatoiement out of these r.620 Dell and need to know what hard drive to put in.

  The steps that you must follow

  -Updated vCenter Server

  -Upgrade of the ESX hosts (because we do a updating of the material we will install 5.5 on our new guests and add them to the cluster and then dismantle our existing)

  -Upgrade VMWare tools

  -Update data warehouses

  ESXi 5.5 has these storage requirements:

  • Installing ESXi 5.5 requires a boot device is at least 1 GB in size. When booting from a local disk or SAN/LUN iSCSI, a 5.2 GB drive is necessary to allow for the creation of the VMFS volume and a scratch 4 GB partition on the boot device. If a smaller drive or logical unit number is used, the installation program attempts to allocate a region scratching on a separate local disk. If a local drive is not found, the scratch partition (/ scratch) is located on the disk virtual ESXi host, linked to the/tmp/scratch. You can reconfigure /scratch to use another drive or logical unit number. For best performance and memory optimization, VMware recommends that you leave no /scratch on the ESXi host ramdisk.
  • To reconfigure / scratch, see Configure the Scratch Partition of vSphere Client vSphere Installation and Installation Guide.
  • Because of the sensitivity of the I/O devices, USB and SD, the installation program does not create a partition scratch on these devices. Therefore, there is no tangible benefits to the use of the great features of USB/SD that ESXi uses only the first 1 GB. When installing on USB or SD, tent Setup devices to allocate a region scratching on a local disk or the data store. If no disk is local or data store, /scratch is placed on the virtual disk. You must reconfigure /scratch to use a persistent data store after the installation.
  • In Auto deploy facilities, Setup attempts to allocate a region scratching on a local disk or the data store. If no local disk or data store is found /scratch is placed on the virtual disk. You must reconfigure /scratch to use a persistent data store after the installation.
  • For environments that start from a San or use Auto Deploy, it is not necessary to assign a separate logical unit number for each ESXi host. You can co-locate areas scrape for several hosts ESXi on a single LUN. The number of hosts assigned to a single LUN must balance the size of the LUN and behavior I/O virtual machines.

• Cannot import VMware ESX 4.1, Patch ESX410-Update01 in nine vCenter

  I just do a fresh install with all the latest software. However, I want to update some 4.1 ESX hosts to 4.1U1. When I try to import the zip file in the Update Manager (http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1029353), I always get a checksum error. However, checksums match those provided by VMware and I am downloading on site (a client vsphere running on the server to update Manager). I retried a couple of times. I even tried another patch via the same procedure and this succesfully worked. Is the buggy version?

  

  try to create a patch to host database instead.  In this reference scenario, you should see U1.  Attach this patch host database to the cluster host / and remedy.

• Minimum number of VMware ESX for a HA cluster

  Can someone please detail the minimum number of hosts vsphere required for a HA cluster?

  I'm planning an implementation of the VMware farm including a number of ESX hosts that will be split into two groups. The first group will include vsphere servers that are hosting virtual machines NOT required for DR via SRM. The second group will be VMware ESX and VMs protected by SRM.

  With respect to the SRM cluster, the number of virtual machines is minimal (5-6 virtual machines) and can run on a host unique vsphere. The thin HA I will include 2 vpshere hosts in this cluster. My question is therefore if 2 VMware ESX is OK for a HA cluster because I'm not sure what should be the minimum number?

  Any guidance is appreciated.

  Thank you

• VMware ESX 4.0.0 in connection mit Windows Server 2008R2 Datacenter (4cpu) - license

  Hallo zusammen!

  I have several questions zu obigem Sachverhalt und hope, dass mir von Euch helped werden kann.

  Wir haben einen host ESX (VMware ESX 4.0.0) den wir via vSphere von einem Windows Server aus, verwalten. Auf dem ESX host wollen wir nun start, die first VM (ins Leben zu find) zu installieren. ES sollen OS installed werden (. ser on W2K3 / W2K8 STD (R2), company / business,...).

  Wir haben also license so: 'Windows Datacenter 2008 R2 64 bit 4 CPU. After we die erste VM installed haben, wanted sharp wir mit dem Lizenzkey der Datacenter license aktivieren. Unfortunately works weder der 'Product Key', noch der 'Virtual Key'.

  WO ist mein Denkfehler? Wie die of ich lizenzsiere auf einem host ESX VM procedures meiner Datacenter license Windows-VM?

  Email ich einen KMS Server?

  Bitte um Hilfe - Danke und Grüße TIM

  Auf einem Windows-Server further

  Ich habe einen Server Hello understand before mit 4-Prozessoren (mit neuankömmlinge bis zu 6 carrots?) und eine MS Datacenter 2008R2 as 4 processors so.

  Wenn nun auf dem vShere Installierst werden die Datacenterlizenzen dem host "OS are" Host the kannst und so many different Windows Server verschiedener color installieren, wie die Maschine these.

  (Die dabei "freiwerdenden licenses können as physical system recycled werden...)

  Die Lizensierung participations eher als "Zuweisung" - stell dir vor, die of the DC licenses klebst an den Server und damit Maschine lizensiert ist die mit data center.

  The Add Installation Aktivierung paper - die Zuweisung hands oder keine.

  Bei einer Aktivierung eines W2K8 STD. servers add to the (ublicherweise) einen VLC (VolumeLizenzKey) der eine unlimitierte Aktivierung allows.

  Wenn nun keinen VLC As, so wende Dich an den suppliers der DatacenterLizenz oder direkt from MS. Mit den entsprechenden Lizenzpaieren und Kaufbelegen solltest VLC key bekommen die.

  VIELLEICHT kannst noch something konkreter werden, um welche Art DC license are all und wie bisher deine Server aktiviert Hat sich (OEM, VLC, detail mit Select vertrag, SystemBuilder...) - eine Systembuilderlizenz ACE falls.

  BTW. a hindert dich daran, every Server STD als eines virtual system einen Datacenter zu installieren? OB deine nun auch STD oder doch keine Rolle spielt so DC application.

  Wenn einen planned Server ACE, den draufklonst oder geckoos193, der dann neu aktiviert werden will ists auch kein problem.

  Einfach aktivieren und ggf. uber die Aktivierung go book.

• Upgrade suggestions to replace euipment in a cluster VMware ESX 3.5

  Hello everyone. I have a Cluster VMware coming off lease 3 years and I'm looking looking for some suggestions to upgrade for the following rental equipment:

  • Cluster VMware ESX 3.5

  • 3 x blades HP Proliant BL460c G1 acting as hosts (2 x Xeon E5345, 12 GB of Ram

  • 1 x EMC Clariion CX3 - 10 c iSCSI SAN with 4 TB Raw (15 x 268,4 GB SAS)

  • Currently hosts 12 Windows Server 2 k 3 VM

  We our currently buying the blades since the acquisition of the fair market value was less than $200. I am currently exploring the following options to present to the owners of the company for more how it will go to the best situation of DR

  1. Stay with current equipment

  • Upgrade to vSphere 4.1

  • Updated all the VMS to Windows Server 2 K 8 R2

  • Acquisition by SAN and blades

  • Re - up the support of at least one year, return to upgrade next year

  • Increase the capacity of SAN

  • Search for Amazon EC2 or Windows Azure failure possible

  2. Stay with blades, buy new SAN with additional capacity

  • Upgrade to vSphere 4.1

  • Updated all the VMS to Windows Server 2 K 8 R2

  • Blades of redemption

  • For new SAN buy either:

  • Celerra NX4

  • HP Lefthand SAN

  • HP Storage Works Smart Array

  • Search for Amazon EC2 or Windows Azure failure possible

  3. Buy new knives and the new SAN, send old blades to a failover data center

  • Upgrade to vSphere 4.1

  • Updated all the VMS to Windows Server 2 K 8 R2

  • 3 new knives to HP to help purchase

  • Intel Xeon E55XX family

  • AMD Opteron 41XX family

  • For new SAN buy either:

  • Celerra NX4

  • HP Lefthand SAN

  • HP Storage Works Smart Array

  • Send the old blades off site with a cheap SAN (DRoBo maybe?)

  • Work on a failover system

  Sorry for the long details, I can clarify anything if necessary. Thank you!

  I would also tender hand to International Computer Inc.. to see what they can do for you... I asked a friend I have who work there, and cover the area PA... They are among partners VMware major/main companies in the northeastern part of the United States, in order to get a quality of their own work (regardless of what you get)... I would also tender hand to GreenPagesto see if they could work with you... I don't know if they cover PA, or Phi, but worth a phone/email to find out... Both companies are major players in the VMware partner space, so I don't think you could go wrong anyway... I worked with people of GreenPages on some projects, a couple of different companies and have always had good experiences with the people of their engineers and sales...

  Most quality partner rep will work with his engineers on the solutions until they present it to you. I know that GP for this, and I do not know what IC is also...

• VMware ESX Server 2.5.0 build-11548 - licenses can be centralized in vCenter 2.0.2?

  VMware ESX Server, version 2.5.0 build-11548

  VC V. 2.0.2 Build 50618

  My current mission is with some legacy equipment and versions.

  When I add an esx host to vCenter (see versions above) - I don't get any options to add the 'module' of license to vCenter. The 3.0.2 host works well with a license from the local host and Add-ons vcenter. Version 2.5.0 host has a configured host license. I figured I could use a license for the host of the server and add vMotion, HA, DRS & as Add-ons of vCenter. Selecting the host 2.5 licenses tab is not activate 'configuration of the host' link or it lists license config below.

  Also, if I should not just use vCenter 2.0.2 for esx 2.5.x guests... please chime in with the grounds.

  Can the server vCenter 2.0.2 licenses treat the add-on (vMotion, HA, DRS) licenses for a range of esx 2.5.x with a local host (Server/SMP) license (s) OR even just centralized? It does for 3.0.2 without effort.

  No - vmotion, HA and DRS is not possible with ESX 2.5 - even if it was possible to use the license server centralized with VC 2.0.x these features of VI - 3 can have be used with older versions of ESX.

  If this is not the case, can I change esx 2.5.x to open ports or to start a service allowing the centralized license mgmt?

  The only way to manage centrally ESX 2.5 license is with VC - 1, x -.
