• Two of the four USB ports on my laptop has suddenly stopped working!

  My laptop (HP Pavilion) has a total of 4 ports USB (two on the left side) and two on the right side all of a sudden my laptop developed this problem, two ports USB on the left side of the laptop no longer works... They didn't stop working completely, because I can still charge my phone via the ports, but they do not detect any storage device I plug into them. The other two on the right side work perfectly... I checked my mobile device manager and the defective thing only seems to me pointed out under "other devices", where the driver for 'Fresco Logic' hub USB root is not installed... it shows "the drivers for this device are not installed (Code 28)" Please, this could be the problem and where can I find the driver?

  Hello

  You are welcome!

  I am pleased that the issue is resolved. Since it works fine, I do not think you have to worry.

  However, you can check this link:

  http://support.Microsoft.com/kb/2654568?WA=wsignin1.0

  To find the version of ports, you can consult the HP manual (specifications).

• can I assign vCPU 32 if the physical host is to have 20 hearts that hyperthreading is disabled

  Dear team,

  I just want to confirm I can assign 32vCPUs to a virtual machine, if a physical host is to have total 20cores and hyperthreading is disabled.

  Please let me know assign vcpus VM is depend on the version of ESXi or VM HW version or is it dependent on ESXI licenses

  need your help on the same.

  concerning

  Mr. VMware

  Hey Linjo,.

  Indeed, it's picky

  I just test it. The drop of webclients vCPU 5.5 only shows the number of logical cores available on the selected host.

• If the ESX host in cluster lost the connection to the storage what will happen?

  Hello everyone

  Could someone clarify if the HA agent monitors the availability of storage on an ESX host or is it only the availability of the network on the vSwitch COS?

  Thanx

  working with your team of storage, they probably have the right tools to monitor and alert to such problems.

  If these numbers seem very good, Don't they?

  From our point of view, it would be ok if latency increases when you increase the load with multiple virtual machines. But as already out doubled over our cluster becomes broken after increasing the number of virtual machines at some point.

  We are currently testing with a subset of four nodes VSAN with the above config. In this group, we were able to turn on 187 load generation machines before that three of the four hosts entered the State "is not responding.

  We wonder if anyone has also made large performance tests. If so, we would be very interested in comments you make. Maybe this helps us to find the fault of our construction.

  Kind regards

  Daniel

  With the help of VMware we discover that the problems we face are caused by virtual machines gen load... each vm is generating 2048 ios in circulation... so with 187 VM on the cluster, we unreal ios in circulation (382976... when I remember the graphic observation of our cluster it would reduce up to 13000 per host) which we will never see in real world scenarios. With this high traffic vsan 6.1 ios has problems and vmware is working on a solution... maybe with 6.2 and qos that is resolved?

  A few other changes:

  -a newer driver for our network cards intel x 710

  -new driver and firmware (beta version of dell) for our h730 perc controller

  and some advanced settings:

  esxcfg-advcfg - 100000/LSOM/diskIoTimeout s

  esxcfg-advcfg - s 4/LSOM/diskIoRetryFactor

  esxcfg-advcfg - s LSOM/2047/heapSize (with these parameters, we were able to create 3 starts - with 7 metal discs and 1 flash device - for each host)

• Copy Clone VM on the remote host?

  We currently have a Vcenter configuration limited to 3 guests.  I am creating a system for disaster, assuming that our main centre of recovery should fail.

  So, I need to program a clone of the VM are held every week - but then I need to copy this clone to a remote host which is not in the same data center, although it IS on the same network.

  Is there a way to achieve side manually remove a host to Vcenter and adding remote host (4th) whenever I want to copy?

  If I copy the clone on an external drive, I have to copy it again to the remote host.  It is 2 instances of copy on the network and which can last for hours.

  I want to reduce it to a single copy and perhaps even automate it with a script, but I don't know everything that the CLI in ESXi.

  Any ideas are appreciated.

  Understandable, I thought you wanted to just copy of VMDK but a clone first takes a snapshot of the virtual machine. This removes the lock on the base VMDK. ESXi can run rsync, but it is not supported. It is perhaps a bit over your head because you have no experience with Linux.

  http://www.virtuallyghetto.com/2011/02/how-to-compile-statically-linked-rsync.html

  What you could do is however if sure the source host and destination have access to the same storage. Then plan a clone to the virtual machine, but leave it turned off permanently. In the case of DR, on the other host, go to the data store, select the virtual machine folder, right-click the .vmx and say file added to the inventory. You can then restart it on another host. Or the DR host only has local storage?

• Installed the new host of the cluster issue

  I have currently two hosts that are in a cluster - I installed a new esxi server to add to this cluster.

  1 set up the vswitch for grouping etc... as the other guests

  2. cannot see other data stores.

  You are using an iSCSI device, I guess?  ESX material for the new host is right for the existing hardware?  If you want to disable the unused adapters, which must be done in the BIOS.

• Media Center Question can I have set up as a server and the other two as clients, each using two of the tuners of the card?

  I have 3 computers running Windows 7 Professional, one of them has a four installed tuner DVB - s2 card. I want to configure it as a server and the other two as clients, each using two of the tuners of the card. I understand the media library is able to use the basic network TV tuning cards, so there must be some way for me to configure the server to send the information over the network.

  Any ideas?

  You will not be able to use your existing tuners like tuner network. Microsoft has
  arrested development of Media Center, so don't expect any new hardware/software to
  appear.

• Not be able to address the multiple host in a cluster

  Recently, we have improved our vCenter to 5.5 from 5.1.

  After graduation we are not able to address the multiple esxi host in a cluster.

  We also tried several remediation option.

  OK, then you can move guests with limitation of do this one by one, right? If so, this is an expected behavior, since there is a limit which allow a maximum of a host by cluster upgrade, see:

• Create the new host to the Cluster and Cluster

  Hi team,

  Have we not document or steps to create the new Cluster and add host to cluster?

  In addition, what are the post configuration that must be done on the ESX host? As switch, Nic, the data store Configuration?

  Should we add the storage front of cluster before adding the host?

  A process document or a step will be really useful.

  We plan to automate the process and any entry is really useful.

  Thanks and greetings

  For starters, it is User Guide PowerCLI, that comes with the installation of PowerCLI.

  And there are a lot of messages and blog discussions in this community that meet some or all of your questions.

  See for example establishment of data centres, Clusters and adding ESXi host VMware vCenter 5.x with PowerCLI

  Storage is assigned to ESXi hosts and for use in a clustered environment, you will probably want a shared storage.

  Maybe you need to split issues separate, more specific issues.

  This would make it easier to respond in this community.

• "Mem.Usage.Average" against the total aggregate of cluster host memory

  Please see the attachment for the whole story.

  Please give me a sanity check on this. I used the "Mem.Usage.Average" as a % against allocated VM MemoryMB. The sum of these calculations escaped by far the actual calculations of the vCenter % memory-based. So, I changed my calculations that you see in the worksheet to use the 'Mem.Usage.Average' against the total aggregate available on all hosts in the cluster. This amount came to less than 1% of my calculations based on vCenter GUI. Am I right against the total aggregate memory cluster host instead of against VM memory assigned using 'Mem.Usage.Average '? Thxs-

  

  SDK is not clear on "total configured memory available or". https://www.VMware.com/support/developer/converter-SDK/conv55_apireference/memory_counters.html Part description of memory used as a percentage of the total configured or available memory.

  
  

  $start = (get-Date). AddDays(-5)

  Get-cluster-location ActualClusterName | Get - VM | Where {$_.} PowerState - eq "Receptor"} @{N = "Mem.Usage.Average"; E = {[Math]: round ((($_ |))} Get-Stat - Stat mem.usage.average - start $start - $finish - IntervalMins 1800 - MaxSamples finishing (250) | Measure - Object - average value). Average), 2)}}"

  
  

  Cluster is 6 hosts with 128G per host for total of 768G (786432 MB of RAM), there are 118 powered on virtual machines

  
  

  
  

  for me the SDK says that percentage reflects the relationship between the memory 'active' in the virtual machine against the memory configured for the virtual machine.

  A configured with 8 GB of memory virtual computer that has 'use' of 25% is actively using 2 GB of memory.

  

  I think that your numbers you get for VMS are biased because of the great period of time during which you take the average (see previous answer).

  You can cross-check the mem.usage.average with the mem.active.average.

  In the following code, I calculate the different 2 meters actual memory used by the virtual machine.

  $clusterName = "mycluster.

  $stat = 'mem.usage.average ','mem.active.average '.

  $vm = get - Cluster - name $clusterName | Get - VM | where {$_.} PowerState - eq "Receptor"}

  $stats = get-Stat-entity $vm - Stat $stat - Realtime - MaxSamples 1

  $stats | Group-object - property {$_.} @entity.name} | %{

  [PSCustomObject] @ {}

  VM = $_. Group [0]. @entity.name

  MemoryMB = $_. Group [0]. Entity.MemoryMB

  MemUsagePerc = $_. Group | where {$_.} MetricId - eq "mem.usage.average"} | Select - ExpandProperty value

  MemUsageMB = [int]($_.) Group [0]. Entity.MemoryMB * ($_.) Group | where {$_.} MetricId - eq "mem.usage.average"}). Value) / 100

  MemActiveMB = ($_.) Group | where {$_.} MetricId - eq "mem.active.average"} | Select - ExpandProperty Value) / 1 KB

  }

  }

  The result shows a specific virtual machine, these two numbers are close enough to be considered the same imho.

  That they should be in fact, the mem.usage.average is derived from the mem.active.average.

  

• Pairing of two VMS (always on the same host)

  
  I was wondering if you can marry two virtual machines together so that in the event of a host failure, they will stay together on the same host.

  You can create a rule to DRS for this (keep the virtual machines together). HA and DRS can complement eachother and in the event of a host failure, DRS will stay two VM together. For this purpose on the modification of your cluster settings part. See a screenshot here:

  

• guest computer must have access to the printer host cannot use

  I have a new Mac, an old Mac, an old Windows machine and printer of Xante AW1200.

  Almost all of my work is done on the new Mac.  I get the old machine Mac or Windows of the drawer on rare occasions, or when I need to print something, because the new Mac cannot use the printer.  (Xante never taken the trouble to develop an OS X 10.6.4 driver for this printer.)

  I would like to get rid of the Windows machine.  I have it successfully migrated to a machine of comments on the new Mac, using vmware Fusion 3.1.3 but I have not found a way to get the computer to see the printer.

  This isn't a complete surprise, as Xante does not provide a driver for their (former) printer and (my new host) operating system OS X 10.6.4 - but they were planning a WIndows XP driver that has always worked well on the Windows machine, connected by the RS232 port.

  The printer also works very well on my old Mac, connected via ethernet.

  Can I connect the printer to the new Mac's ethernet port.  Of course, the Mac cannot work with it.  But could the guest computer use Windows sound driver to manage the printer?

  None of the four standard ways of printing seem applicable: ThinPrint because the host cannot use the printer.  USB because the printer is not a USB connector.  network / wireless because I do not have my old Mac running all the time.  Hello because I think that it requires that the host can see the printer.

  It certainly isn't a frequently asked Question.  Sorry, my situation is so unusual.  But the printer is special enough for the work that I do.  Any tips?

  Thank you.

  If you have a router on your site then you should be able to connect the printer to the router, configure it as needed, and then accessing it in the comments as a network printer.  Note: The guest network should be configured as connected by a bridge to access in this way.

  Another option of network which is doable, but a little more difficult to set up, is to fix the printer directly on the Mac with a standard CAT5 Ethernet cable, not a Crossover as suggested in the Ethernet Port of Mac being automatic detection User Guide.  You would then manually configure the IP address, etc. on the printer and network bridged on the comments and even if Bridged his only access to the printer on this network adapter.  Then use a second network in the guest configured as NAT, if you do not also use Bridged on that, to enable the client to have access to other resources on the physical LAN to the host, such as Internet access, etc..

• What is the correct procedure to take a host of a hav?

  Disconnect the host in your cluster, and then remove host.  Or evacuate all customers outside the host, put in maintenance mode, and then remove the cluster
