ESXi 5.1 - insufficient resources to meet the level of failover configured for vSphere HA

• who can help me with "insufficient resources to meet the level of failover configured for vSphere HA.

  Hello world

  We tried to gif a 14GB of ram and make server complete a booking for her.
  This is a server for the exams and the vendor told us to do.

  I can't any more then 5500MB reservation on it, when I anymore that I get
  "Insufficient resources to meet the level of failover configured for vSphere HA.

  We have:

  2 X 5.1 ESXi hosts
  Each host has
  2 x processors (8 Cores each) with HT active.
  255,75 GB of Ram

  vSphere HA has been activated.
  Admission control policy is enabled and that the ability to failover is 1 host.

  What is the problem here?

  Thank you
  Ernst.

  
  

  Admission control policy is all about to give you the kind of guarantee that if the host failure happens then there will be enough resources to perform the successful failover.

  in simple terms, it comes to reserve the resources of failover.

  I would recommend going through the notion of vSphere HA, reduced control policy the following document.

  https://pubs.VMware.com/vSphere-60/topic/com.VMware.ICbase/PDF/vSphere-ESXi-vCenter-Server-60-availability-Guide.PDF

  From the Page number 22, the details that you need to study is given. Focus especially on part calculations Slot size of it.

  in your case you HA vSphere with number of failure of host to tolerate as admission control strategy defined.

  This means system will calculate CPU and memory slots out of the resources in your cluster, and the total number of units, it will keep some resources like reserved for failover, and others will be available to be used. It all depends on how much failure of hosts that you want to tolerate.

  now in your case, if you try to increase booking one of the virtual machine, which will then affect the number of locations in your environment, and so reserved ability to failover is violated, the system will not let you do what you want to do. As the energy on a virtual machine, or growing booking a powered VM etc..

  If you find that you have enough resources in your cluster and due to some virtual machines with very large cpu or memory reservation, number of places is less than you can still manage the settings some advanced in vSphere HA configuration, but I strongly recommend, try to take the help of someone who has done it before.

  also try to go through other admission control strategies which are explained in the document for more inputs.

• Not enough resources to meet the level of failover configured for vSphere HA

  I have a cluster of vSphere based 5.0 based on ESXi 5 knots 2.

  When I try to start a virtual machine, I get an error saying that there is "insufficient resources to meet the level of failover configured for vSphere HA.

  If I turn off an another VM the problem disappears and I can turn on my VM.

  If I try to turn on the virtual machine, I have already turned off, I get the error again.

  It seems obvious that there is a lack resources or some setting is misconfigured, but even after reading the forums and manuals, I am unable to locate the critical resource or parameter that is not correct.

  Based on my experience or vSphere server and ESXi servers are overloaded.

  I have an another similar cluster of hosting a larger number of virtual machines with no similar problem.

  This performance counter and this setting should check to identify the bottleneck?

  Concerning

  Marius

  To check reservations for virtual machines, I would select the Cluster in your vCenter inventory, then select the resources"" tab.  Which displays the child objects of the bunch (VMs, Resource Pools, vApps).  There you can watch settings of CPU resources and memory.  You'll want to watch the column of "Reserves".

  To find the size of the slot and places available, look at the tab "Summary" of your cluster.  There is a tile marked "vSphere HA.  In this mosaic, there will be a link for "Advanced Runtime Info" which will open a new window with the location information.

  When the Admission AP policy is set to "Number of failures of host cluster will tolerate", HA has a very pessimistic view of your resources, since it must be able to handle all the possibilities.

  Another option would be to change the admission control strategy in settings of Cluster HA to "percentage of resources reserved for failover.  It reserves a part of the resources for use by HA in the case of a failover, rather than trying to calculate the size of the individual virtual machines.  With a 2 cluster nodes, I think it a relatively safe bet to set these values to 50%, as your worst case scenario HA would be losing a single host on 2.

• Not enough resources to meet the level of failover configured for HA

  Hello!

  This error message is pretty well documented on the VMware site and elsewhere. It is received when it exceeds the capacity of (CPU and RAM) calculated the HA cluster resources.

  That said, despite what I understand, I can't understand why I runner of am limited to VMs than 6 (otherwise, the I get message error en the title) on cluster of United Nations HA (FT not DRS) of 2 servers, while the alors que les ressources resources averages used are about 10 to 20% only of those available for.

  I have 40GB of RAM and 19.2 GHz per server. I calculated according to the method explained here: http://www.yellow-bricks.com/vmware-high-availability-deepdiv/.

  Maximum reserve of United Nations I 2 GB and 2.2 GHz on VMS (less pay some), but the limits are left in general 'Unlimited '. The 'Actions' are 'Normal '.

  In short, here are the numbers that vSphere client gives me pour the cluster:

  CPU:

  Total capacity: 37440 MHz

  Reserve capacity: 27424 MHz

  Available capacity: 10016 MHz

  Memory:

  What Miss me?

  How about you? You drive your virtual machines with what reservations? (I tried to roll them up to 0, but some virtual machines (originally imported from GSX in ESX 3.5 and ESX 4.0) won't roll or plant.)

  P.S. Yes! I know that I can from this error by clicking "Allow VMs to be powered even if they violate the constraints of availability", but I like to keep the option of 'prevent' up to ' that I understand better what happens... or doesn't.

  Thanks in advance...

  Hello

  I have one exception that has a reservation... others are not and everything works fine.  I suggest you check your VMs.  There the maid to do following an import.  The exception is pour terminal type servers or in some circumstances you can have some problems.

  Hello

  I don't know if anyone can point me in the right direction, but I'm having a problem with the configuration of the HA on a cluster for the moment when he returned with the warning following 'insufficient resources to meet the level of failover HA.

  Please could someone point me in the right direction as to where the issue could be?

• Not enough resources to meet the level of HA failover in the cluster in data center

  Hi guys,.

  We just migrated our ESX 4 clusters to a new VirtualCenter (version of Base 2.5 - & gt; 2.5U4), and one of the clusters is showing «insufficient resources to meet the HA...» "error message.

  First of all - is it possible to refine what host is at the origin of the problem (or VC), or is it a real issue with ability?

  I followed some VMTN articles to avoid the usual bugs: -.

  • Ensure all host FQDN, and domain names are lowercase in VC - home | Configuration | DNS and routing

  • Make sure while tiny in/etc/hosts, sysconfig, /etc/vmware/esx.conf and/proc/sys/kernel/hostname on all 4 hosts.

  • Deactivated / reactivated HA on the cluster

  • Looked into the VC vpxd*.log the period of time during which HA was past - but don't know what to look for?  There are a few warnings such as:

  • Warning 'Local' 5940] FormatField: optional unset (vim.event.VmUuidAssignedEvent.vm)

  • "VpxProfiler" 2752 WARNING] InvtHostSyncLRO::StartWork took ms 2203

  • Warning 'Local' 6032] FormatField: optional unset (vim.event.HostDasErrorEvent.message)

  • "PropertyJournal" 5380 WARNING] ERProviderImpl & lt; BaseT & gt; : _GetChanges: global version name overflow host-600

  • .. .etc

  There are 4 hosts in the cluster - and capacity seems ok.  I watched [doc ability vmwarewolfs | ] http://www.vmwarewolf.com/HA-failover-capacity/ [ ], but am not sure that I totally understand it.

  4 guests look like:

  1 - 32 GB RAM (22 in use) / 17600 Mhz CPU (5548 current usage)

  2 - 64 GB RAM (31 in use) / 17600 Mhz CPU (7661 current usage)

  3 - 32 GB RAM (18 in use) / 17600 Mhz CPU (4210 current usage)

  4 - 64 GB RAM (20 in service) / 17600 Mhz CPU (7440 current usage)

  How can I work if there are really insufficient resources or is it a bug that will be bypassed by creating a new cluster and migrate more hosts in maintenance mode?

  Thanks for your time guys!

  You have all vms with a high reserve (memory or cpu)? If so, this can cause the HA being too conservative admission control algorithm. The guide of availability of vSphere for details on the algorithm of "slot" - http://www.vmware.com/pdf/vsphere4/r40/vsp_40_availability.pdf, especially pages 13-16. Some of the mentioned options are only available in vSphere 4, but the basic mechanism is also applicable to the VC 2.5.

  VC 2.5 does not expose the details of accommodation through the user interface as vSphere 4, but you can get some information in the vpxd newspaper. Try the power on a virtual machine (you should get an error message on failover insufficient capacity) and look in the logs of vpxd for 'Housing news' - the following lines should have a few details - download those to this topic if you need help their deciphering.

• Computer memory virtual is increased from 6 to 8 GB and now vm fails to power on with the error massage not enough resources to meet the HA failover, attached screenshot

  Computer memory virtual is increased from 6 to 8 GB and now vm fails to power on with the error massage not enough resources to meet the HA failover, attached screenshot

  The message is usually due to the Admission HA and reservations control configuration memory set on one or more virtual machines. With the default configuration HA calculates the sizes of slot based on the memory and CPU. Any reserve on a virtual machine could increase the size of the slot and lead to fewer available seats. What you can do is either to reduce (or eliminate) reservations about the VM (s) or set admission control to a percentage rather than the host failures tolerated.

  Well, who has not responded to my problem, but it was eventually fixed by a support guy with the company who sold me the desktop PC. As I understand it, it was a problem of file sharing. Seems he had to undo sharing all my records on the desktop, then re - share once again, since when I did not have this particular problem. But it's obviously not ideal (in MS eyes at least) to the network of computers with different operating systems.

• insufficient capacity to meet the configuration of the clustered resources

  Hello

  We run 3 ESX 4.0 with Vcenter 4.0

  In preparation for the addition of new 5.0 ESX host, I installed a new server Vcenter 5.0 and moved the 3 ESX servers to the new Vcenter.

  I've reconfigured HA, but it comes with the following error messages.

  It used to be OK with Vcenter 4.0

  I changed the "failure of the cluster tolerate the host" 2-1, but still the same issue. "

  I don't know what the problem is (except if there is a problem with HA with hosts on 4.0 and Vcenter 5.0).

  Looking at Cluster resources, I have:

  Total CPU: 58064 Mhz, reserved 27000 Mhz available 31064 Mhz

  Total memory: 178970 MB reserved: Mo 124168,60, available 54801.41

  I restarted the Vcenter, and also for each host, I made a "Reconfigure for Vsphere HA'.

  I noticed that when I did the reconfiguration of the VM (very few) got now alarms "HA Vsphere Virtual Machine failover failed"

  I have no attention to 3 hosts ESX4.0 in ESX5.0, as new material will be added soon, and it will install directly with ESXi5.0

  and then all of the virtual machines on the hosts ESX4.0 will be migrated to the new material, before withdrawing from the old hardware ESX4.0.

  If anyone know what I should do to get HA works well again?

  Thanks in advance

  Even a reserve increases the size of the slot and can cause problems with HA admission control as you see now. I explained this to Re: unable to poweron due VMs size connector cpu not available

  If you really need reserves, I would recommend to set the control for admission to 33% in your case (with 3 guests).

• Not enough resources to meet the HA failover

  I have two ESX servers in a cluster - each with 32 GB of memory and only 8 virtual machines running on ESX servers. Seven of the virtual machines have 2 GB of memory that has been, and no reservation of memory - the HA slot should be 2 GB as the eighth virtual machine is our virtual Center Server, and 2 GB is the reserve memory for this virtual machine.

  I have a strict admission control on this environment policy, which should work as 2 VMS in GB(maximum memory reservation for VMs) X 8 = 16 GB of memory and the "number of failures of the host in the cluster can tolerate" is set to 1. I have no idea why, but when it is disconnected from our server ESX tempoarily I received the message "insufficient resources to satisfy HA failover.

  There seems to be a lot of resources - both in terms of CPU for a failover to the other host ESX to occur.

  Someone at - it ideas?

  Do you mean on HA not to act in case of failure of management agent? Availability guide (http://www.vmware.com/pdf/vsphere4/r40/vsp_40_availability.pdf) explains what protects the HA. See page 8:

  VMware HA protects the availability of applications in two ways:

  • It protects against a failure of the server to automatically restart the virtual machines on other host in the cluster.

  • It protects against defects of application by continually monitor a virtual machine and restore in the event where a problem is detected.

• Can the NAT of ASA configuration for vpn local pool

  We have a group of tunnel remote ipsec, clients address pool use 172.18.33.0/24 which setup from command "ip local pool. The remote cliens must use full ipsec tunnel.

  Because of IP overlap or route number, we would like to NAT this local basin of 172.18.33.0 to 192.168.3.0 subnet when vpn users access certain servers or subnet via external interface of the ASA.  I have nat mapping address command from an interface to another interface of Armi. The pool local vpn is not behind any physical interface of the ASA. My question is can ASA policy NAT configuration for vpn local pool.  If so, how to set up this NAT.

  Thank you

  Elijah,

  NAT_VPNClients ip 172.18.33.0 access list allow 255.255.255.0 10.1.1.0 255.255.255.0

  public static 192.168.33.0 (external, outside) - NAT_VPNClients access list

  The above configuration will be NAT 172.18.33.0/24 to 192.168.33.0/24 when you go to 10.1.1.0/24 (assuming that 10.1.1.0/24 is your subnet of servers).

  To allow the ASA to redirect rewritten traffic the same interface in which he receive, you must also order:

  Hello

  I would recommend you take advantage of the offer of discounts for Windows 8.

  Normally, it would be better to buy a computer with the latest version of Windows pre-installed because the computer could be certified to run the pre-installed operationg system.

  However, in this case, all the computers that are available with the upgrade of $15 are all designed to run the final version of Windows 8.
