"When to add more hosts" policy?

Hi all

I would like to hear what some of you are using in what concerns the addition of new hosts in your cluster of politics?

I would like to be more proactive on a few occasions, we ran into memory resource constraintsbefore that we have addressed the issue.

That means stopping the deployment of virtual machines until more resources is achieved.

I want to be in front of the 8-ball and I was wondering how solve you? Get additional resources when your cluster reaches a certain threshold for example of the use of memory or a certain percentage of memory overcommitment. I'm sure it's different for each workplace and all experiences are welcome.

see you soon

  • vCenter crashes when you add esxi hosts

    When I add an esxi host to vcenter, it crashes when it comes to installing the agent vcenter at the bottom of the screen. Then my vi client will expire and say he lost the connection. What of weird is that my vcenter is just a virtual machine sitting inside the physical esxi server, I am trying to add. My connection is both high speed broadband as well. I don't understand not for vcenter IN the esxi server, I try to add, you would think that the connection should be fairly quick. My vcenter vm using windows xp pro 32-bit.

    When you run the add in vCenter you are connected to the local ESX and vCenter through the vSphere client?  I don't think that cause this problem, but if you are connected to two, during the add, delete the vSphere client connection in the ESX and try to add it again.  In addition, if you publish newspapers at the time of failure:

    ESX

    / var/log/vmkwarning

    / var/log/VMkernel

    var

    vCenter

    Journal of vpxd

    Is this the only ESX add that causes the problem?  You can VMotion the vCenter to another ESX Server and try to add the ESX problem?

  • No wireless network under Vista 32 bit when I add more than 2 GB of RAM

    Hello

    I am running Vista 32-bit Ultimate Edition (Service Pack 1) on my desk, I had 2 GB of physical memory installed on my system. but I recently had to increase the ram to 4 GB.

    I got D-link Airplus G + DWL-G520 + wireless adapter PCI, which worked very well with my OS. but since I upgraded my ram to 4 GB. He stopped to show me any network or to create or connect to another, using a d-link's router which works fine with the other portable 2 of my friends.

    I even thought about updating my operating system to 64 bit instead of 32 that I use 4 GB of ram, but d-link does not support this product so I'm not able to find the 64-bit for this network card driver.

    y at - it a patch or upgrade that I do on my vista ultimate 32-bit if I get my network wireless connected to my office with the same network card?

    Thank you guys

    Cordially :)

    Hello

    If the 4 GB of RAM is important for you try a newer pci adapter.

    Xtreme G wireless cards come out kind of standart.

    This card is inexpensive has x 64 driver too and works very well.

  • Add a host to cluter running vm on vcenter

    Hello

    We have three processors PROLIANT DL360 G6 Intel X 5560. One of them has a virtual machine that acts as a server vcenter.

    I create a cluster for HA and added 2 & 3. When I drag and drop the host who, as the installed vcenter, I get an error

    A host with virtual machines under tension or suspension can not enter a VMotion compatibility improved cluster that is configured for a lower CPU feature base of the host.

    The CPU on all servers is the same, but I also noticed that the EVM under summary host mode for the host with vcenter. Now, I don't know why it is disabled. I did the bios settings processor that VT is enabled.

    I tried the steps in KB 1013111but, which does not help because I can't drag the host with vm in this cluster.

    Can someone please. Thank you very much

    If I understand what you're trying to do... you have created an active cluster with VCA and try to add to the host that is currently running the vm vcenter.  With active EVC, you can't snap all guests who have vm running or suspended on it.  You can uncheck either CVS (which you should not need since all processors are the same, unless you want to add more hosts in the foreseeable future) or attempt to vmotion the VC on one of the other guests.  I don't know if it will allow you to do so, but worth it.

    If it won't allow you to vmotion, you'll have to do a manual migration cold.  Turn off the VC, connect directly with the client to the host with the VC vsphere, remove the virtual machine inventory, then connect to one of the other hosts, browse the data store, right click the vc .vmx file and "add to the inventory.  Then you should be able to feed the VCenter and add your last host in the cluster.

  • Ports vmk NFS considerations when you move a host of distributed 1 switch to another

    Hi everyone, I wonder if you can help with the following...

    I currently have a number of ESX host that accompany the dvswitch0 for connectivity management and NFS.  VM networks has already been migrated to new dvswitch. The following assumptions are correct?

    I need to remove a vmnic from the current dVS, so that I can create a standard vswitch and migrate vmk0 (network management) to it before removing the host of dvswitch0?

    When I did it and I delete the host of dvSwitch0, I lose connectivity for my NFS vmk? Or will they continue to work as I have the info ip configured locally on the ESXi host? I've recreated the PG for NFS on the new dvswitch bearing the same name and config like dvswitch that I want to spend

    If the connection is lost, I guess I need to migrate a vswitch standard before removing the vDS, identical to my management network of my NFS vmk. And then migrate them all using the wizard when I add my host to the new dwswitch

    If the connectivity will not be lost, I guess when I add the new dvswitch host and migrate my vmk0, the vmk NFS will appear in the PG on the new DVS as my exchanges were confiigured with the same name?

    Is that correct the above?

    Thanks in advance


    If the connectivity will not be lost, I guess when I add the new dvswitch host and migrate my vmk0, the vmk NFS will appear in the PG on the new DVS as my exchanges were confiigured with the same name?

    As long as there is a valid vmnic attached to your destination vSwitch and a group of ports on the VLAN, the migration of your NFS vmk interface will be successful.

    I suggest doing this kind of work, while the host is in maintenance mode; There will be a small window of time during the migration where the host loses connectivity to the NFS data store.

    I'm doing a video for confirmation that has pictures on a soundtrack. I would add the persons name and bible passage before each group of students of photo. I am using the two lines of text slides so that their names are larger on top and their passages are smaller underneath.

  • Add more disk space for the ESX host

    Hi all

    I need to throw more disk space to my ESX hosts.  I know how to bind records in Navisphere and present to the ESX host.  Once in the VI client, I "think" I need to go to the host and do a rescan of the HBA or something like that?  I'm a little unsure of the market of part VI to add more disk space.  Could someone just point me in the right direction?  Please note that I am looking to add more disks to existing hosts in existing clusters.  It adds no storage to a new host... rather an existing one.

    Thank you

    Jonathan

    You are on the right track.  Re-scan storage card, under the configuration tab select storage adapters, select the adapter and click on the link of the new analysis.  Then go to the storage section and there should be a link in the top right of the screen that says storage Add.  Click on that and it will guide you in adding/setting in form/naming of the new disk.

  • Unable to add previous hosts to vCenter device

    Greetings.  We are migrating our guests to new hardware.  We had three hosts for running ESXi 5.5.0 - 1331820 with the vCenter device on one of them.  Everything worked well.  In the process of moving virtual machines around, vCenter device has been deleted (intentionally).  We recreated the device of the OVA 5.5.0.5201 vCenter and ran through the Installation Wizard as previously.

    Now, when you add one of the existing hosts to vCenter, it finds the host and displays information.  When the user clicks on finish, it works quickly up to 80% and the host appears, and then disconnects.  The log shows: add host independent, added host, unable to connect host computer in the data center; connection error host, removed in the data center.

    The error showing is: cannot communicate with the specified host (x.x.x.x). 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.


    Now the stupid thing is that we can not even add the host on which the vCenter unit is on.  In addition, all hosts and vCenter unit are on the same network of management.  There is no firewall doesn't block all ports.  I read through a lot of the display of the Knowledge Base, and most is in regards to incorrect IP addresses or ports blocked or similar.  I checked through everything and could not find anything wrong.


    Last thing is that we amazed the ESXi host that had the vCenter device on it and re-installed 5.5.0 - 1623387 ESXi (version a little more recent than before) and reinstalled the that vCenter device exactly as before.  Now we can add that the host but still cannot add other hosts.  So it appears the issue is something with the hosts and not the device vCenter. 


    Anyone have any ideas?

    I run in to the same kind of problems with other factors.

    FWIW, have you tried the following in this order? 1 stop the vpxa on host, 2 service. Stop the service vmware-vpxd on the vcenter server, 3. Start the vmware-vpxd on the vcenter server, 4 service. Start the serivce vpxa on the host. Then try to add.

  • Add more memory esxi

    Hello

    I intend to add more memory to a server R910 esxi 4.1 production in a cluster. I intend to do following steps:

    VMotion all the vm off the host

    Put the host in maintenance mode

    Host of the judgment

    Add memory

    Start the host

    Check if additional memory

    We did the test memory on the server when it was put in the cluster.

    Is it necessary to do a memory test again, while adding additional memory?

    Nope.  You don't need to get out of DRS, just perform a manual migration of VM (put it in maintenance mode).  Now he died in maintenance mode. Then when you add memory and start it... This isn't on the cluster, giving you the chance to test the memory... (to see if it's visible).  At the start of the BIOS memory test just...

    When you see that the memory is fine, then you can exit maintenance mode...

  • Cannot add the host to the distributed switch

    Hello

    Updated some time a go to vSphere.  Environment has 2 hosts and I left it with standard switches.  Today, I thought I'll add a distributed switch and use the extra features etc.  I added the switch d however when I come to add a host it there are none listed?  Can someone tell me how do I migrate from standard to distributed please?

    Kind regards

    Stuart.

    First of all. Do you have an Enterprise Plus license? Distributed virtual switches not working Enterpise more licenses or if you are using the Evaluation Version.

    Secondly, you have all available vmnic? unless a computer host a vmnic unused, the hosts will display not.
