• Script of PowerCLI to capture ESXi host CPU & memory

  Hi all

  I'm having the time more difficult to find a script that will give me ESXi host CPU and memory. I just need something simple, if there is such a thing?

  Example of what I'm looking for:

  Host name	Ability of GHz CPU	CPU GHz used	Free GHz CPU

  Host name	The memory capacity	The memory used	Free memory

  Help, please.

  You mean like this

  Get-VMHost-name MyEsx |

  Select Name,

  @{N = 'GHz CPU capacity'; E = {[math]: tour ($_.)} (CpuTotalMhz/1000,2)}},

  @{N = "GHz CPU used"; E = {[math]: tour ($_.)} (CpuUsageMhz/1000,2)}},

  @{N = "CPU GHz free"; E = {[math]: Round (($_.))} CpuTotalMhz - $_. {{(CpuUsageMhz) / 1000,2)}}.

  @{N = "GB memory capacity"; E = {[math]: tour ($_.)} (MemoryTotalGB, 2)}},

  @{N = 'Memory used GB'; E = {[math]: tour ($_.)} (MemoryUsageGB, 2)}},

  @{N = "GB free memory"; E = {[math]: Round (($_.))} MemoryTotalGB - $_. {{(MemoryUsageGB), 2)}}

• Share of CPU between ESXi hosts in a cluster?

  Is it possible to configure a cluster with a pool of CPU resources such as all CPUS of all ESXi hosts in the cluster are in the pool and if a virtual machine starts using more CPU that's current host has it can draw another ESXi host CPU to deal with?

  A virtual machine can use CPU only from the host where the virtual machine works... There is no way to allocate CPU of multiple hosts to a single virtual machine.

• Impossible to withdraw, migrate, etc., VM on the ESXi host

  Earlier, the room of my loss of cooling infrastructure hosting servers suffered vSphere causing several ESXi hosts to closure without notice due to excessive heat.  Needless to say that the results were chaotic.  While I recovered/restored most of the systems, a problem seems to persist.  It is a virtual machine that is impossible to remove, move, etc. due to locks on files active.  The option in the .vmx to "Add to the inventory" file in the data store is also disabled.  However, this virtual machine is not displayed with a "vim - cmd vmsvc/getallvms" command.  In fact, investigating the locks on files, it doesn't appear with a ' vmkvsitools lsof | grep VM_Name command"and no result back with a ' ps | grep VM_Name command.  The host in question has also been restarted and updated (5.1 update 2, Update 3) so a simple reboot does not clear the locks.  So, the question is; How can I get rid of this virtual machine so I can properly re - add to vCenter?  Any help would be appreciated.

  Then just do a kill-9 20156 and you are all set - this kill everyone and goes out by the force of the virtual machine and your hair will be free

• Can I use the total amount of resources (cpu/ram) of two esxi hosts if I place a cluster so that a single VM gets all resources?

  I use vCenter 5.1 with two esxi 5 guests, both exactly the same (Evga SR - 2 pc with two Intel x 5670 each) with the exception of the disk storage. Processor x 5670 a 12 hearts if HT is enabled. Since then, I have 4 of these processors that would be 48 cores. Each processor is clocked at 4 GHz for a total of 16 GHz. Each host would also 24GO of total Yes 48 GB of ram.

  I doubt that this is possible, but what I want to do is to install a virtual machine like Win 7 x 64 and give all these resources to it... all of them (perhaps leave some carrots and ram aside for guests of esxi, of course). This vm is run to 16 GHz? It would be nice if we could create a cluster with a Setup like this and give the "total available resources' for a single virtual machine running on a esxi host.

  I doubt that this is possible because I've tried that before and it wouldn't let me create a virtual machine with this number of nuclei or ram because he said that they were not available or something... as if to suggest that I can only use the total amount of resources to AN esxi host.

  There may be another way I could give this 16 GHz machine?

  Could not assign more resources to a host to a virtual computer.

• ESXi host does not synchronize with NTP - causes HA config failures?

  Hello

  We are currently implementing some Cisco UCS systems. We using blades Cisco UCS B200 M1 (x 5670, 48 GB of RAM)

  Everything seems to work fine except these little things, which seems to be related.

  1 NTP synchronization is not happenning, or happening very slowly.

  2. a 10 cluster host, when it is configured for HA, has many guests who fail to be configured for HA (for example we had only 2 guests get properly configured for HA out of 10).

  Initially, I thought REP 1 and 2 were not related, but then I remember reading somewhere that the ESXi host must have simultaneously for HA to work.

  On question No. 1:

  10 guests have a difference of 5-6 minutes between them. Curiously, the first hosts that are connected to a HA cluster, if their duration is similar, they wil work.

  But others are more than 1 to 2 minutes off, they will fail. Our NTP is configured on 2 internal NTP servers, which syncs with the outside world - the 2

  NTP servers are:

  The default gateway of each ESXi

  The network Core switch

  We know that the NTP servers work correctly because our advertising is synchronized with them and we checked on our domain controller local time main external time source.

  Debug information

  Output of /etc/ntp.conf

  ~ # cat /etc/ntp.conf
  restrict default kod nomodify notrap nopeer
  restrict the 127.0.0.1
  Server 10.*
  Server 10.*
  driftfile /etc/ntp.drift

  Everything has been configured through the GUI, I show the output of ntp.conf for confirmation.

  We tried to restart the hosts (without success).

  Everyone knows what we can do to solve this?

  Thank you

• The CPU suddenly very high low host CPU

  Hi all

  I was struggling with a particular host for awhile and am unable to access the root of the cause. What we have so far:

  Physics:

  1 host, 2 quadcores with HT technology (total 8 cores, 16 logic due to HT), 24 GB of ram

  HP Proliant DL380 G6

  Virtual:

  1 x Windows 2008R2 DC/FS 2vcpu

  1 x Windows 2008R2 SQL 4vcpu

  1 x Windows 2008R2 Exchange 2010 1vcpu

  1 x Windows 2012R2 RDS currently 8vcpu

  Recently, the old 2008R2 RDS has been replaced by the new 2012R2 RDS. This went well, nothing special, no complaints, that rent because it was quite a bit of snappyier than the last.

  Then, (and I did not understand what happened yet, could have been power failure) after about a week the Esxi host froze and we had to restart. Servers began and everything was fine, until the problems started.

  The 2012R2 virtual machine currently maxing out at 100% cpu usage in Windows Task Manager, between all the virtual cores. This can be achieved by something as simple as the launch of chrome and Outlook at the same time. Performance on this virtual machine is terrible. All other virtual machines are affected also, extremely high CPU usage in Windows, maxing out even with simple tasks. If I open vSphere and check the CPU usage, it's nowhere near capacity. The RDS virtual machine did not exceed 3000 mhz maximum.

  What we have tried so far:

  -Reboot the host

  -Restart the virtual machine

  -The power management has changed compared to the High Performance HP OS Control setting, and the powersetting to high performance in vsphere. I can see through esxtop that all hearts are at c0 permanently. (Could not verify this before because of ILO2 failing to display this when HP high performance mode is activated)

  -J' tried all sorts of Vcpu assignments, until 1 vcpu/1core 8 sockets on the 2012RDS. There is no pool of resources, there is no reserves (I tried those who, unfortunately, no effect)

  -Close all VM except one (to check if there is some sort of contention cpu), always the same.

  I think something is gone belly up when the host rebooted, simply unable to understand why, and apart from the crazy CPU usage, the server running now stable.

  Any input is greatly appreciated.

  Have us shut completely the host, took off all power physically and reconnected. After that, CPU returned to normal. Upgrade to ESXi for good measure.

• 6u2 ESXi host nested on VMware Workstation for Linux referee v12

  Hello all, I have

  I have a lab environment virtual running in VMware Workstation for Linux v12, and my ESXi hosts do not work correctly on one of the virtual networks. All my troubleshooting suggests a problem with nested ESXi hosts that may be a bug, but I want to assure you that I did everything properly first. That's why I post here with the hope that if I made a mistake that maybe someone else can point out he me.

  Physical system

  8 core Intel Xeon 2.1 GHz CPU

  128 GB of RAM

  OS - kernel Linux 64 - bit w/3.19.0-32-generic Linux Mint 17.3 (fully updated from this announcement)

  VMware Workstation 12 Pro - 12.1.1. Build-3770994 (fully updated from this announcement)

  Nested ESXi host VM

  ESXi v6.0.0 (Build 3825889, completely updated from this announcement)

  4 cards 'physical' (only 3 used for now)

  -all use the e1000 NIC hardware virtual, but also tried vmxnet3 NIC with no difference

  -vSwitch0 use vmnic0 & 1 vmnet16 of virtual network in a pair of active / standby

  -vSwitch1 uses vmnic2 on network virtual vmnet18

  -vmk0 used for management on vSwitch0 and vmk1 for iSCSI on vSwitch1

  -"Promiscuous" mode and forged passes enabled on all Port vSwitch groups (activating or turning off these features makes no difference)

  Test performed until now

  I checked that all the IP addresses and network masks used are correct.

  With the help of vmkping I ping other nodes on the network vmnet16 with success.

  With the help of vmkping I tried to ping the other nodes in the network vmnet18, but that has failed.

  I have depolyed other non - ESXi VMs on the vmnet18 network, and they are able to ping each other, but are unable to ping or ping by the ESXI host.

  I tried various material virtual NIC as mentioned before, but without changes in the results.

  I tried to use only local network instead of the vmnet18 guest network segments with no change in results.

  When I find out the status of the network adapters on the ESXi host through vCenter or host incorporated client vmnic0 & 1 time display network information, but vmnic2 shows no networks. Yet, I know that there is a network with different VM communicate on it. Moreover, I was able to get all of this work on a Windows system running 10 Workstation (this is the laptop that my employer gives me with).

  Having built nested ESXi labs on different platforms as well as physical environments in the past, I'm very confused as to why I can't get this special configuration to work. At this point my gut tells me that this is probably a bug any with the nested themselves ESXi hosts. Since I can get all this work on vmnet16 including the management of ESXi hosts and the VCSA that I use, I am sure that my vSwitch configuration is correct (other than the IP address space and vmnic configurations is bascially the same). Because I can get other virtual machines to communicate over the network vmnet18 I don't see how can be a VMware Workstation for the issue physical Linux host. Is there something obvious I'm missing here? I read on the ESXi hosts nested under VMware Workstation after having known problems and bugs with networking. If anyone else has experienced this?

  Thanks for any help others can provide!

  Kind regards

  Patrick

  Well, the problem is now resolved. The problem was what covelli was trying to explain, but I couldn't because the physical host network adapters being mentioned.

  The problem on the Linux host, but it was a problem of permissions with the virtual Ethernet adapters. The following article has the fix:
  With the help of Ethernet virtual cards in Promiscuous Mode on a Linux host (287) | VMware KB

  Even if I launched the workstation under the root user I have yet met this problem and which still makes no sense to me, but change the permissions solve the problem. I was not getting an error message on my Linux Mint and Ubuntu system, but when I tried on a second box of Linux Mint that I just got the error has been generated, and the error message was the above link it contains.

  So, here's what I learned:

  (1) the question has nothing to with a VMware Workstation definition that you can configure.

  (2) the question has nothing to do with a physical network card.
  (3) the question has nothing to do with any vmnic on the nested ESXi host.

  (4) apparently virtual Ethernet adapters are not the correct permissions when created.

  All you have to do to fix this is:

  (1) open a terminal.

  (2) run the command ' sudo chmod a + rw/dev/vmnet * "(don't forget to run this each time that you create a new virtual network).

  You can also create a group, as shown in the link above and simply give this group the correct permissions. Personally, I think it's easier to just give everyone the rw permission.

  I appreciate the help that others have offered. I did not understand what was asked for in previous answers because of the terms that have been used.

• VIServer - connect to an ESXi host

  We have virtualized just the server that runs our vCenter services.  Now, we found that we would like to increase the number of processors available on the virtual computer.  Unfortunately, hot CPU is not activated on the VM, then we are stuck in the dillema that need vCenter to change the settings on the virtual machine, but not being able to change the settings when the virtual machine is running.

  We try to use PowerCLI to achieve this.  If I understand correctly, we should be able to connect directly to the ESXi host to change the settings of the virtual machine while it is turned off.  However, I was unable to establish a connection to the host using Connect-VIServer.  When I try the following:

  SE connect-VIServer esxihost.domain.com - root - password rootpass user

  I get an error message can not complete the connection due to an incorrect user name or password.  I am able to connect to our vCenter very well using Connect-VIServer, but it serves me in my scenario.

  I noticed that Connect-VIServer only supports HTTP and HTTPS, but our ESXi hosts only run SSH.  It is possible to connect to a host without vCenter ESXi running?

  Oh ffs... too bad.

  All our hosts use the same password with the exception of a handful that are different (for some reason that no one can remember).

  Guess which include this particular host is in?

• -= Decommissioning of a license key on ESXi host in order to import in vCenter Server Essentials 6 =-

  Our company recently bought a license for VMware vCenter Server 6 Essentials for vSphere (VCS6-ESSL-C) with license keys for VMware vSphere Essentials 6 for 1 processor (ha6-ESSL-C).

  I accumulated vCenter Server 6 on a physical device and assigned the new relevant license key, as well as installed Update Manager Server on this machine. This instance seems to be functional and functional.

  Now, I'm trying to import 3 x ESXi hosts in this environment which have the license keys from an environment "vSphere advanced 5. These 3 hosts are administered under an instance of VM of vSphere vCentre, that I want to the Commission under this license and the license on these hosts is no longer valid after a takeover of the company.

  Question:

  (A) Comment can I get correctly to the setting of these hosts so that I can use the new vSphere license key 6 that I received?

  (B) should I upgrade these hosts to v6 ESXi befin environment to use this new license key?

  (C) do I need to disable features on the hosts in order to apply to apply this license key "6 of vSphere Essentials?

  (D) what is the correct order for doing all these things to use this new environment vCentre?

  Thanks in advance for any assistance given.

  Concerning

  Grant

  I havn't done it myself yet, but I think you should be able to achieve your goal, follow these steps:

  -downgrade license keys CPU Essentials to v5 im Portal MyVMware

  -the value of the new vCenter Server Evaluation Mode (actually maybe not necessary)

  -Add the licenses of Essentials v5 license vCenter inventory 6

  -Add hosts to the new vCenter Server ESXi 5.5 and assign licenses Essentials guests

  -re - assign the license previously removed to vCenter Server

• 5.5u2 ESXi host will not mount CF data warehouses

  I am the admin in a test lab, so many times I have to "make do" with what I have for the material.  I recently reassigned a R910 Dell with 64 GB memory in a 5.5u2 ESXi host.  It has some storage SAS (2.5 to) and some (CT 11) directly connected FC storage and some FC HBAs for use by VMs to send data to the tape library.

  Recently, we had a power failure, and this host does not reconnect to the CF storage when she returned to the top.  (Duty to "make do" with what I means not having is not the capabilities of UPS).  I can tell the host of HBA see it properly and sees the LUNS on RAID controllers, but refuses to mount.  I go through the add storage Wizard, and he sees that there is a store of data storage VMFS, but always refuses to mount.  I also tried to remove the redirection to the two FC HBA that have been set up for this purpose, but it made no difference.

  I have now three users unable to work because they cannot access their virtual machines on storage of this FC.  I can't even transfer them off to use the SAS storage form.

  I think it might be the cause file system damage, but I'm not sure.  Someone at - it suggestions?

  Have you ever tried to set up data warehouses from the command line (see, for example, http://kb.vmware.com/kb/1011387)?

• ESXi host running 6 VCSA disconnected from the vCenter

  Hi guys,.

  I have a weird problem with my vCenter build 6. Single cluster of ESXi hosts. Running VCSA 6.0 and 6.0 ESXI. Making a storage of the vCenter vMotion initially got stuck at 77% and the ESXi host running the disconnected from vCenter vCenter. But I can connect directly to the ESXi host with vsphere client and see the vCenter VM works perfectly well. If I try to manually connect host ESXi and vCenter, I get the error "Failed to contact the host specified") both are in the same subnet and VLAN. I can migrate to other virtual machines without problem. I even restarted the host and yet I am not able to connect to vCenter. The host connects to vCenter if I reboot vCenter, but after a few minutes, disconnects again (even if no task does run on this topic.) I have no HA or DRS enabled at this point that I build this new environment and only presented a single LUN as a store of test data to the cluster.

  Any ideas?

  OK, I think I fixed that or have at least a work around. So the underlying question was hiding ID mode/CPU EVC. I'm under the cluster to a level of EVC to reduce until I have migrate workloads from old environment and I think that this created a problem for the unit vCenter. To resolve this problem, I turned off the unit, directly connected to the ESXi host that had the camera running, edited the virtual machine and reset the masking of CPUID. Also, I've hidden the flag NX/XD of the guest. It's temporary (I hope) as once I increase the EVC to the Haswell, I will expose the NX/XD comments and test. For the moment, it is of the workaround I did. It may be of some use to someone.

• Should the RAM for an ESXi host replaced the same ones remaining?

  Hello

  We are running a cluster of servers ESXi 5.1 - 2 of them are Xeon E7440 2.4 GHz (64 GB of RAM) and 1 of them is Xeon X 5460 3.16 GHz (32 GB of RAM).

  Currently, the use of the memory of all three ESXi hosts are about 60%.

  We will replace the Xeon X 5460 server with a new physical server.  We would like to ask for your opinion how much RAM you must order (my manager of door on the cost of the new server).

  Thank you

  Hi again Tony,

  1. No, it is not high at all. You should begin to worry about this, after reaching approximately 85-90%.
  2. My short experience with clusters of memory-unbalanced, adding that more memory would be a lot like the DRS manages memory locations & 'kindness host' in the right direction, but I'm not really sure how that would turn out in the long term. If you decide to present more memory to your server, it would be possible to upgrade the other two guests sooner than later
  3. Yes, ask the seller would be the right thing to do. Please note that you will need to put in place an enhanced vMotion to conform to your next "older" CPU then, because you'll have something other than X 5460. I guess you'll have to "intensify" a generation or two, depending on what you have found.

• 5.1 ESXi host is showing that does not

  Hi all

  We are to vCenter 5.5 with Environment 5.1 ESXi hosts. On one of our ESXi hosts, we sometimes get to see 5.1 ESXi, (build 799733) host is not responding and the virtual machines on this subject are displayed as status disconnected at the end of their names.

  When this happens, we are able to ping on the ESXi host and virtual machines are also able to ping / react to what is good, but he continues to be on different hosts at different times, all what I do when this occurs is to try to reconnect on the ESXi host and it connects fine and machines virtual hosting on she will return to the State normal and everything will be normal on this host. I want to understand why this is happening at different times and on different hosts of ESXi and ensure that this should not happen again in the future or find the before root cause is even worse.

  so, could someone please look at this and let me know where to start troubleshooting this to find the root cause.

  Thanks in advance

  Your vCenter and ESXi host is on the same subnet? In any case, I recommend you take a look at this article and apply the patch suggested: VMware KB: hosts ESXi and ESX disconnect randomly VMware vCenter Server
