• separate subnets for the ESX/ESXi management ports (vMotion, manage, FT, etc..)

  Is it better to have all of your VMKernel ports on the same subnet or subnets separate (one for each role, iSCSI, management, vMotion, FT)?  Are their potential problems with either scenario?  Please include the ESX and ESXi.  I want to get my setup just as it should. Please let me know also if you need additional information.

  I have licenses for ESX and ESXi, but I'm leaning toward ESXi are all vSphere 4 Update 1.

  Hello

  In fact, you have to use separate subnets for your vmkernel ports but they can run on the same thread. You can share a subnet between a vmkernel and service console, but not between two vmkernels. Just like that. So yes, you need to use several subnets.

• How to control vmotion license to the ESX Server

  I have 5 servers ESX 3.5 U3 in my vCenter.  Two are using host license and three are in a cluster and using the server license assigned by my license server, that runs on vCenter.  However, my ESX servers two stand alone using the host license receive a license of vmotion by my license server and my ESX servers in my cluster but cannot get a license of vmotion because their attributed to the wrong ESX Server.

  How can I get the vmotion license released by the ESX servers who don't need and make it available on my ESX Server who need?  My three ESX servers in cluster shared storage for vmotion and don't have my two stand alone ESX servers.

  I tried simple things, like the disconnection of servers and ESX servers in reconnection vCenter, re-reading of license files, restart the license server, etc..  license and vCenter server is 2.5 U4.

  Thanks in advance.  Jim

  go to the configuration tab and click Networking, you have a Port VMkernel configuration?  If so, edit click the vSwitch properties, change your VMkernel port settings and uncheck the box that says VMotion: enabled.

• How to report the current time on the ESX host in to a csv file with the following

  Hello guys

  I have the script next where I make the required details except the current time on the ESX host. Anyone can guide me please.

  I want to integrate the following for loop of the above for loop and ge the output in a single table.

  foreach ($esxcli in get-vmhost | get-esxcli) {"" |} {Select @{n = "Time"; e = {$esxcli.system.time.get ()}}, @{n = "hostname"; e = {$esxcli.system.hostname.get (.hostname)}}}

  Add-Content - Path '$hostVC, $hostCluster, $hostHost, $hostNTP, $hostTime' $hostInvFile - $ hostTime is where I want to get my host right now.

  I'm vcenter, esx name, name of the cluster, host of the ntp server address, but I need the host thus present.

  Thanks in advance.

  Thank you

  vKar

  Try changing the line where the script retrieves the VMHost to this

  $vmhosts = get-VMHost-State connected. Name sort

  This way the script will be only to ESXi nodes that are "connected".

• FQDNs for ESX environment when DNS servers are VMS within the ESX environment

  Hello

  I was wondering,

  When the implementation of a new infrastructure from scratch, with an ESX cluster from scratch

  and when the servers DNS themselves will run inside the cluster,

  Then, it is advisable to use IP addresses instead of the domain name COMPLETE for the right ESX environment?

  Here's what I've done so far:

  -installed 1 ESX host

  -installed donain controller as VM

  -installed PSC and VCSA

  -created the new cluster

  -installed the second ESX host, added to the cluster.

  I installed a VM DC as the first thing after the installation of the initial ESX host, I could have started using the domain name COMPLETE for the ESX environment at this time.

  However, I didn't do it.

  For installation of the VCSA and when you add ESX hosts to the cluster, I used IP addresses instead of the FQDN names.

  It seems stupid and dangerous for me to use domain COMPLETE the ESX hosts themselves, because the domain controller is running in the cluster.

  So I used IP addresses only to ensure the ESX HA cluster and the characteristics of heartbeat stay ok if something were to happen to the DNS server.

  However, the VCSA installation and when you add hosts to the cluster,.

  the MISTLETOE gave me a warning, indicating that it is preferable to provide a FULL domain instead of an IP address name.

  I am of the opinion that if you have no physical DNS servers, it is not a good idea.

  My opinion is that when your nameservers inside the ESX cluster itself and you do not have 2 redundant external DNS servers, so it is not wise to use the FQDN for your ESX hosts, PSC and VCSA setup.

  In my view, using the property intellectual property is much safer in this case.

  I was wondering what is your angle on it.

  Do you see the same way, or have different opinions?

  Hi smetter,.

  It is advisable to have a working DNS for vSphere environment however the use of DNS for things like vSphere HA have been removed in more recent versions of the product. Refer to the section of the guidelines of the general network of this document for more details: https://www.vmware.com/files/pdf/techpaper/vmw-vsphere-high-availability.pdf

  With this in mind I wouldn't be worried about use of FULL domain for the addition of services like the ESX host, etc.. Failure where HA would be restarting the virtual computer, there is no dependency on DNS so it will continue to work as expected and, subject to the availability of resources the virtual machine starts on another host.

  According to your vSphere licenses, you may also like to consider the implementation of anti-affinity DRS VM to keep your DNS Appart servers and on different hosts. This can prevent your servers DNS are declining when the failure of a host. You must have Enterprise edition or later for this.

  Kind regards.

• Cannot add the ESX 6.0 host to vCenter Server 6.0

  OK, I'm testing laboratory a vsan 6.0 cluster.

  I have my running 6.0.0 esx hosts and vcenter server is 6.0.0 also.

  I have the services platform on a virtual machine and vcenter on another. I was able to create a data center, then a cluster below.

  Then I went to try to add a host to my group and I get this error...

  Failed to contact the specified host (hostname\IP). The host may not be available on the network, may have a network configuration problem, or that the management on this host services may not respond.

  
  

  Per this KB: KB VMware: Add a host VMware ESXi/ESX from VMware vCenter Server fails

  
  

  I confirmed that my vcenter server and platform services server can see all esx hosts. From the vcenter server, it can ping the host esx and PuTTY can access all of them. I even installed the client and it can connect to all esx hosts. I used the netbios name, IP and FULL domain name and they all work.

  I have only a single subnet, so this isn't a problem. DNS resolution works in all areas of both sides, vcenter esx hosts and host esx to vcenter.

  
  

  I am quite puzzled.
  

  
  

  
  

  OK, after working with VMware on this issue, I think that I thought about it.

  All my hosts are DL360 G6 servers.

  My hosts are run the same build «VMware-ESXi-6.0.0-2494585-HP-600.9.2.38-Mar2015.iso» ESX Downloaded from HP.

  All buildings are in trial mode.

  After placing a call to VMware, they had me build some ESX VM, the services of the platform and the vcenter VM on an ESX host. We suspended because it took all day to go upward.

  Once I woke up all the parts (sql server, esx vm, server platform & vcenter) in virtualization nested, I created my data center, then Cluster then added the ESX host.

  The hosts added properly, no error. Then I remembered when I installed ESX inside a virtual machine, I am angry that the iso, I had the habit of HP does not work in my VM nested due to virtualized hardware.

  Then a fire came into my head. We will rebuild all of the physical cluster but NOT use the CV provided the iso file but use VMware provided iso file "VMware-VMvisor-Installer - 6.0.0 - 2159203.x86_64.iso".

  I did it today. I have rebuilt all hosts with the provided iso file VMware ESX...

  Spun SQL Server vCenter, service platform, all VM VM VM you need. My AD & DNS VM are on another server, so he has been upwards all the time.

  Connected to the web interface (yuck!).

  Created my data center...

  Created my Cluster...

  Add all my Cluster hosts.

  All of this worked!

  Therefore, if you encounter the same problem, I'm plan to generate your with the provided iso file VMware ESX hosts and try it. In my case, the provided HP iso file didn't work properly for me.

  I also downloaded the iso file of HP 2 other times to make sure and do a validation test and it did the same thing.

• Reboot the ESX host as possible while on VM snapshots exist?

  Can you safely do a reboot of a host ESX VM there was on this host which are off (of course), but have a snapshot exists at this time?

  Because we restart some ESX host but you also have to install some Windows updates on the virtual machine on these hosts. Normally, we take a snapshot of the WM, install updates, restart, check if everything is working fine, and then remove the snapshot. But after a reboot the ESX host we also check if the VM have started and are working very well. In this case, it would cost me 2 restart and check for WM

  When I could do the snapshots, installation of updates, power off the virtual machine, reboot the ESX host, turn on the virtual machine, all check and then delete the snapshots, it saves me time. Only thing I don't know and can't find is so it record to make a snapshot is by restarting the EX host and if the snapshot can be deleted after reboot normally.

  Welcome to the community,

  don't worry, a restart of the host is quite VMs, regardless of whether they are active or not snapshots.

  This circumstance may be linked to a sata cable issue, with the possibility of temporary loss of connectivity, which could result in data loss/corruption, I realize.  It is a laboratory box.  Especially say that the 2 VMDK he complains (trying to light) is both on the grounds of a single physical disk. Data, read and written to the speaker, since the problem are very good (which indicates the wiring problem was resolved, and the VMFS5 file system seems to be in good health).

  No photos.  No related clones.  Just a 2012 Windows Server based VM, with several drive letters in, with those underlying files VMDK residing on different stores of data VMFS5.  Implemented end (these drives aren't really so huge), but far from running out of physical space for the data either. Everything is working great for months, until today, trying to it turns on again.

  Good news, the best result I could hope. No data is lost. No corruption of the VMFS or NTFS don't drive in the virtual machine. Nice!  Saved me a few terabytes of data restoration and learned a little more on file system of troubleshooting along the way.

• The ESX itself, Antivirus?

  Welcome!

  Knowing that ESX is Linux, we could apply that no AV is necessary.

  However... it produces AntiVirus installed on the ESX itself?

  Ideas appreciated.

  ESX is not a Linux, the ESX Service Console used as management layer is derived from Linux, but it should not be thought that Linux. You should not install antivirus Console of Service ESX Linux, if you do, you can introduce very serious problems for your ESX stability or functionality.

  Anti-virus for any Linux host is a huge mistake in any case, security in the Linux/Unix system must be based on totally different approaches.

• Copy Virtual Machine on the ESX Server windows file server (files)

  I made a copy of a computer virtual with Vmware converter and it is sitting on the windows file server, is there a way to copy the files to the server, ESX4?  Something like a copy and paste?

  Thanks in advance!

  Simply right click on the data store you want to place the files on (Summary tab when selecting one of the hosts connected to this data store), select "Browse the data store" and then use the button "transfer files to this data store. You can use it to download a folder or file from a target, that you access from your system. It might make things easier if you create a folder in the store of data first, and then download the files one at a time. Make sure that the virtual machine is turned off when you do.

  Another option might be to vMotion/migrate it from current storage to a data store in the ESX environment. I did not the same type of migration before, it will or will not be, works correctly. I moved files VM from a source, see my workstation, up to a data store that the ESXi host has a connection to before without problem (with the virtual machine powered off course).

• Restart VM after you restart the ESX host

  Hi all

  I am using VSphere Enterprise.

  Here my little question, makes VMs always restart after back us running or stopping of the esx host?

  In esx 3.5, when I reboot an esx host, all the virtual machines in this host are still alive (without restarting).

  Pls advice

  Thank you

  The only way, a virtual machine can rest running when it is running on ESX server is restarted is that if FT is activated - in this case, the connections will be seamless switch to the virtual machine "shadow". This is a feature of vSphere, so I don't see how you did not the VMs restart on your ESX 3.5 - even with VMware HA environment, there will be a short break because the VMs will be will be running on the other nodes in the cluster.

• help - vm to 100% with Betclic resources cpu, but the ESX host to 15% cpu

  Hi all

  5 * HP BL460c Blade each with two Quad Core Xeon E5450 and and 8 GB of RAM.

  ESX 3.5

  VirtualCenter 2.5.0

  DRM and active HA.

  I need assistance with resource pools. Currently I have them all together for:

  • expandable

  • unlimited

  for the CPU and memory. I tried without reserve and with reservations, and it is indifferent to the result.

  I'm running a server SQL2008 (2 * vCPU, 3.5 GB of RAM) which is pretty hard. and from time to time the cpu usage spikes to 100% (6 GHz) and saturate at this time here. When I go to the graphs of the ESX host, I see up to 3 physical processes responsible... and all the others are dormant...

  I'm working on why he no longer not affected resources of the ESX host. I thought that because of the resource sharing (unlimited), he could catch resource from the pool of resources of the parent (unlimited). And our Installer is very very little used - so much processing power/mem available spare parts.

  I have also some really stupid questions:

  • with SMP, 1 vCPU means only 1 pCPU host is used?
    I never thought that this true, but in this example, it seems that only 2 pCPUs on the host are used... maybe 3,.., it is difficult to tell from the graph

  • a virtual machine can use more resources from a host at the same time?

  with SMP, 1 vCPU means only 1 pCPU host is used?

  I never thought that this true, but in this example, it seems that only 2 pCPUs on the host are used... maybe 3,.., it is difficult to tell from the graph

  Yes, assign you a resource equivalent to a virtual machine to the host.  Therefore, if you assign 1 vCPU which is equivalent to a unique Jepp on the host computer in the slot.

  a virtual machine can use more resources from a host at the same time?

  No. a resource pool is on a cluster, but VM inside this POOL can only use a single host resources.  The case is from ESX can use DRS to load balancing force of the VM, the pool determines the overall consumption and that you assign VM accordingly.  But ESX is not yet there to physical resource take other hosts.  What ever host is on, it is that the only place these resources can be achieved.

  What process the SQL 2008 taking up the CPU process?  I think it's SQL Server, in which case it is not that you can do.  One of the reasons that I discourage using VM for SQL, SQL works not virtualized.

• HA does not not as expected on the ESX host

  Hello

  I have a cluster with ESX 3 (v3.5 Update4) node that is configured to use HA & Drs During a practice session to the ESX host that I found that if I simulate a hard failure of one of the nodes in the cluster, ESX all guests arriving to run on this host VM will automatically starts not themselves on another ESX host after x amount of time. What I've done so far to solve problems is the following:

  1. allowed Virtual Machine put in power under the Configuration tab on each ESX host. Then, I moved that no matter what VM Autostart submenu in there appearing. This step is repeated on each ESX host

  One thing to note after that: when the host has been stopped, the virtual machine would properly failover to another ESX host but not itself power on. I got feed manually on the client.

  2. I disabled the resource constraints under the Cluster Edition settings Menu to enable the machine to power on no matter what

  There is nothing to change the question

  3. I fiddled with the priority of restarting the virtual machine in question to see if it would help, but it made no difference

  4. I enabled Virtual Machine control and settings left to 'High '.

  It has nothing

  There are two messages that I keep seeing in the case where the window of the Cluster:

  Failure of failover for the guest in question Warning Message

  Not enough resources for the warning of the cluster failover

  There are many resources available, so I do not know whence this second message. DNS seems in good condition I can solve the hosts & guests all with success in a direct and reverse search.

  My goal here is to have the guest virtual computer turn itself on one of the other guests of the ESX cluster.

  Any help would be appreciated... Thank you

  Look in "response to isolation" on setting HA. Did you put it "Leaves the virtual machine" setting turned on or turned off?

  If market, your host another try not to put the virtual machines from the virtual machines might still running on the original host, which can cause some collide ie.swap in use, the locked configuration files & etc.

• Strange when network problem the ESX servers powered

  Hello.

  First of all, do not know if this is the right forum but I hope you can help.

  I have a question where to chance the firewall stops responding during a small number or a host/pcs/physical server randomly on my network. This problem started since the launch of VMware and two ESX servers. I think that its a problem ARP as erasing the NIC ARP cache on the windows computer that has trouble to the solve the problem temporarily. A permeant fix is to cut the ESX servers, which is obviously not a solution.

  Ive changed the firewall's Pack but have the same problem. Any thoughts on what to check on ESX to see what is the cause? My ESX servers currently have a unique NETWORK card on the LAN vSwitch for simplicity and a distinct vSwitch for 10 gb iSCSI, which is directly connected to the San. Very simple.

  Thank you

  Ive found my problem.

  My SAN, a HP MSA2040 manages a network of 192.168.200.x for internal use according to HP support. Even if id changed IP address of management to another network that it stills works this range. Therefore, the map was updated to the ARP tables and sending request to the bad MAC/IP who just happened to be the IP address of my gateway to some network hosts. Crazy stuff.
