• Java Virtual Machine Launcher displays, "Unable to access c lib\MP3Rocket.jar" from recently, I get this error message when I try to open my file sharing program "MP3 Rocket". HOW CAN I FIX OR STOP THIS?

  I tried to uninstall and re install MP3 Rocket and the same error message appeared.  The error message window is titled "Java Virtual Machine Launcher" and the error message said: "Unable to access c lib\MP3Rocket.jar" Please HELP!  Any ideas on a fix so I can get my music back!

  Hi I have just solved this problem by going to Java Virtual Machine Launcher poster, "Unable to access c ... . and from there to the MP3 Rocket help site and the connection. From there on, I was able to download MP3 Rocket Pro, but I've changed where I put it, I created a new thing entirely next folder that I knew I had the program back and working again. I did it without having to go through the default programs bit. Give it a try. It is simple and easy. Sometimes I think that we have an overload of information and I found happened to me.

• Copy of the data of the disk of the virtual machine on a Local disk is too slow

  We have recently implemented vMware view.   We vSphere 5.5 and 5.2 and made Desktop visualization server.

  We have SAN as HP 3Par and Esxi hosts are HP ProLiant DL380p Gen8

  Now all trying to copy the data from the disk of the virtual machine disk of the local computer are too slow. But if we are writing data from Local disk on the disk of the virtual machine is normal. And copying data between the two virtual machine disk is also fast.

  Thanks in advance for your help

  Dear all,

  Thanks for your help.

  We have analyzed the issue in 360 degrees, and we also examined your entries. Finally, we found the problem. It was that a defective fiber link has been creating the problem.

  We have recently implemented vMware and this flaw in fiber can also happened during this period. That's why we thought it may be because of vmware.

  Thanks again for your help

• Virtual machines, run extremely slow when the console is consulted 2 virtual machines Windows Server 2008 64-bit, Windows Server 2003 32-bit, 2 VMWare for virtual machine

  I'm in a difficult situtaition here.  I am the daily contact with a new client.  My linux guy, who is also my boss who is very busy, asked me to do some research trying to find answers for what's not on this server. We have a dual Quad Core 2.5 Ghz Lenovo server with 10 GB of ram.  2 500 GB hard drives are Raid 1.  We run Virtual Server VMWare 2 on a Debian with Gnome installation as a user interface for the side of things Linux.  Grub is the boot loader. There are two virtual machines running on the server.  The one machine that serves as a domain controller is a Windows SBS 2008 Server 64 bit, and the secondary machine has no responsibility domain.  The second machine is a Windows Server 2003 32-bit.  the 10 GB of ram 6 GB is allocated to the SBS server and 4 GB to the 2003 server.

  The problem I am running into is that everything is so slow, especially if I connect remotely to do any sort of administration on the network.  Some examples of issues I've noticed is that as soon as I log on the server via Remote Desktop SBS console management Windows Server spike to 80-95% CPU usage and it will not stop unless I close the management console.  Another instance is that if I open Backup Exec 12.5 on the SBS server it will kill the speed of the processor as well.  Long story short, there are a lot of machine to do what we need to do, but something is not configured right and non of us know what it is.  Another point to note is that the server has been in production for about 3 weeks, and the server seemed to have locked up just twice.  My professional guess is that over time, some chose thing is eating causing the crash of the memory.

  Sorry I do not have much technical insight on this topic, but this is the best I have to offer.  Any questions you all have, I'll ask my people and see if I can answer, but I could really use your help here.

  Thank you in advance,

  Heath

  2 things:

  1 you really need hard drives more than 2 in a RAID 1 for proper performance under load. More disks the better. Although I don't think that's what your problem is, he'll probably be the problem Next you will do.

  2. I don't know exactly where the configuration file is on your box of Debian for VMware Server, but you should consider adding the following options in the configuration file (on windows, it's the vmware 'config.ini'):

  prefvmx.minVmMemPct = "100".

  MemTrimRate = 0

  sched.mem.pshare.Enable = "FALSE".

  mainMem.useNamedFile = "FALSE".

  If you do some research, you can read about what these options (the largest is the memory page sharing - it should only be left on if you have a bunch of similar virtual machines running on the same box, that you don't have.) I honestly know why this is on by default, he kills the CPU when virtual machines are running different operating systems). These are the options that I now use standard in VMware Server deployments, with huge performance increases after you have added the. Just give a try.

  Edit: Also make sure that you have installed in your virtual machines VMware tools.

• Virtual machines are not able to access the network after you have moved the host

  We moved our 4 ESX host to a different physical switch and now our VMs cannot access the network.

  I can access the host via client vsphere.  Our host has 2 network cards.  They are both members of the vSwitch0.  I have 1 VM network defined, and they are both members of it.  The network adapters, vmnic0 and vmnic1 are also part of my VMkernel which I do not know that I need because I have 1 ESX Server and do not use iscsi or NFS.

  the two cards are also part of my service console.

  According to my host "configuration / display: vitual switch, it looks like all my virtual machines are defined to use the vswitch."

  the two physical network adapters is connected to the same switch.  I did not go to any configuration on the switch.

  

  The steers would be appreciated.

  Thank you

  Paul

  

  Welcome to the community,

  It sounds as if the physical switch ports are not configured correctly. Please check that port security is disabled on the switch (switchport mode access) ports and spanning tree portfast is (if any).

• VMware 6.5.5 cannot import the virtual machine that uses 2GB "disks of split.

  Hello

  I'm using VMware Workstation 6.5.5 under Win XP. I tried to import a virtual machine that was created by using the option 'Split' virtual disks into files of 2 GB. The import fails and presents a pop-up: ' Conversion Assistant/cannot determine the guest operating system. The log file includes the line "could not find the disk cofortcol3v01 - cl1.vmdk. This file does not exist of course, there are more files cofortcol3v01-cl1 - s001.vmdk, cofortcol3v01-cl1 - s002.vmdk and so on. The machine virtual original (cofortcol3v01) has been created under VMware Workstation 5.1, and it does not under Workstation 6.5.5.

  Is this a known problem in the conversion utility? Is there a work around for this problem?

  Thank you.

  -Phil Anzel

  FYI... VMware Workstation peut import a Virtual Machine that uses twoGbMaxExtentSparse discs.

  The log file includes the line "could not find the disk cofortcol3v01 - cl1.vmdk. This file does not exist of course, rather there are files cofortcol3v01-cl1 - s001.vmdk, cofortcol3v01-cl1 - s002.vmdk and so on. The machine virtual original (cofortcol3v01) has been created under VMware Workstation 5.1, and it does not under Workstation 6.5.5.

  Is this a known problem in the conversion utility? Is there a work around for this problem?

  The problem is that you're missing the "disk DescriptorFile", "cofortcol3v01 - cl1.vmdk" and which is why it's a failure and not a limitation of the Conversion utility.

  Also if you actually had a Virtual Machine created in VMware Workstation 5.1 you can simply run directly under VMware Workstation 6.5.5 without having to run the import command.

  Anyway, if you have a backup that you can recover the file "cofortcol3v01 - cl1.vmdk" then you should be fine and if you have not then a new can be created.  If you can archive (compress) files vmware*.log (usually 4 of them) in a single zip file archive and tied him to a post in response, then one of us will create a new file "cofortcol3v01 - cl1.vmdk", based on the information contained in files vmware.log for you, if you don't know how to do it yourself.

• How users share a virtual machine with the level of access under total control?

  Hello

  In our Lab Manager environment, we have created workspaces and users can create and share virtual machines in these workspaces. The problem is the level of access only I can see when users share virtual machines is read-only. How can users share their machines with other users with the full control access level?

  Thank you.

  It is a constraint of security designed to prevent the full control permission, being too easy accidentally to give everyone in a system.

  The answer depends on whether you have PF3 or LM4.

  Behavior of PF3: share to everyone in an org is read-only, while sharing a physical person should give you full read/write/control

  LM4 behavior: share in all the world in an org, individuals selected in an org or anyone in a different workspace == read-only, while in the same workspace gives you the opportunity.

  That said, total control: the ability to deploy/undeploy it or change the settings of the virtual machine, NOT if the specified user has write access the console.  The distinction is quite important.

  Also, page followed, but he had the wrong information, there may be an arbitrary number of connections of the competing console to the same VM (oh, I'm sure that there is a limit, but I did not deliberately try to find).  It does give the impression that several people are faced with the same mouse and keyboard...

• My Vista machine is very slow to start

  Original title: MY VISTA IS VERY SLOW

  my computer perfomance is very slow.it takes more than 3 minutes to complete beginning up.how can I increase my performance?

  My personal opinion is that the attention of a lot of people pay to how long it
  is required to start is not justified. Assuming that the speed of the computer is
  otherwise satisfactory, it is generally not worry. Most
  people start their computers once a day or even less frequently. In
  the general scheme of things, even a few minutes at the start is not
  very important. Personally I turn on my computer when I get up the
  morning, then go get my coffee. When I come back, he did start. I have
  don't know how long it took to start and I do not.
   
  However, if you don't want to solve it, it may be due to this
  programs start up automatically and you can stop some of them
  to start this way. On each program, you do not want to start
  automatically, check its Options to see if he has the choice of not doing
  Start (make sure that you actually choose the option do not run, not)
  just one 'do not display the icon"option). Many can easily and better be arrested
  in this way. If this does not work, run MSCONFIG from the start. Run
  line and on the Startup tab, uncheck the programs you want
  starts automatically.
   
  However, if I were you, I wouldn't do it just for the application of
  the minimum number of running programs. Despite what many people say
  you, you should be concerned, not with the way * a lot * of these programs
  you run, but * that *. Some of them can degrade performance severely, but
  others have no effect on performance.
   
  Don't stop all programs to run willy-nilly. What you need to do
  is to determine what each program is, what its value is up to you which
  the performance cost is its running all the time. You can get
  more information on the latter with research on the internet and ask questions on
  Specifications here.
   
  Once you have this information, you can make a smart informed
  decision on what you want to keep and what you want to get rid of.

• Is it possible to migrate a virtual machine to thin provisioned disk?

  I have about 100 VM in a resource pool dedicated to called "Archive"... Well, archiving.  These virtual machines are currently powered off but every now and then we will get pulled for a developer to work on (they are for the most part, the virtual computer with client customizations if they are changed about once a year).  I'm quickly running out of space on this SAN but all discs are thick provisioned and using the disc is maybe 20-30% on average.  Also, I want to move them to a new large store of data I created for them.

  Of course, I choose Migrate & gt; Change store data & gt; Thin provision in vSphere Format and I'm done.  However, it would be nice to not do this 100 times.

  Move-VM does not seem to be capable of this, and I have not been able to find a workaround.  Is there a way to convert the thin and then perhaps Move-VM? Or I'll just on this all wrong.

  Thank you!

  You can try this script?

  He's moving vms to data store 'EMCSAN:Datastore01' trying to change the format of storage for Thin

  $dsView = Get-Datastore -Name "EMCSAN:Datastore01" | Get-View -Property Name

  $vmView = $_ | Get-View -Property Name
  
  $spec = New-Object VMware.Vim.VirtualMachineRelocateSpec
  $spec.datastore =  $dsView.MoRef

• Qosmio X 505-Q870 with "slow" disk access

  I "ve got a month several old X 505 870 with 4 GB of memory and TWO Hitachi 7200 RPM SATA II 500 GB hard drives." The system is mainly used for initial review of digital images, with each image being about 20 MB. To access the images to display previews is noticeably slow. YES, the system is set to the best of my abilities. YES, both drives were and are REGULARLY - defragmented show 0% fragmentation. YES, I threw the original o/s with all the trial versions, stupidity and boiled and installed W7 64-bit. YES, all the pilots I know are up-to-date, including the Intel storage drivers. NO, other than Side-By-Side periodicals errors that appear every day, I get application or system errors.

  In Bridge or Lightroom, I don't get bound to the CPU, but this thing beats a bit on the disks and takes MUCH longer than the desktop system to display pictures. YES, the office is a slightly faster processor, but it
  a also records standard 7200 RPM for images, and it is MUCH faster to retrieve and display images in Bridge or Lightroom...

  Y at - it any PRACTICE (no, layout 2, 500 GB SSD drives is NOT practical) thing that can be done to improve the performance of disk on this box, because right now it certainly isn't no matter what speedster?

  It's OK if you use own preinstalled OS but I would like to know if you have noticed the same problem with the original operating system preinstalled.
  You have installed all necessary drivers for Win7?

• CS6 Adobe installation is very slow if access to the internet is blocked

  Hello

  I noticed that our facilities Adobe CS6 (using package AAMEE) were surprisingly slow (as in five hours on a fast machine).  I have worked for the cause of the problem and am posting here in hopes it helps someone else has the same problem - in addition, if someone from Adobe is reading this, it would be nice to get it fixed, at least for future versions. :-)

  The problem is that our machines have no direct access to the web sites on the internet, i.e., port 80 traffic is blocked by the external firewall.  I discovered that Installer CS6 tried repeatedly to contact various websites, including crl.verisign.net, probably in order to validate digital certificates on the files in the installation package.  Each such attempt was set to expire before the next was made.  Firewall Configuration Windows to block these attempts reduced at the time of the installation of five hours thirty minutes.

  On Windows 7, this command allows to install a firewall rule that blocks traffic outbound port 80:

  netsh advfirewall firewall add rule name = "block www" dir = action = block protocol = tcp remoteport = 80

  Once installation is complete, this command deletes the rule:

  netsh advfirewall firewall delete rule name = "block www.

  For later versions (Adobe CC and beyond) you should block port 443 as port 80.

• Windows 8.1 ReadyNas with sync - when online very slow file access

  Hello

  I use the latest firmware 6.4.2 and network of NAS drives, I use with the Windows synchronizes 'offline' feature to make them. Operating system is Windows 8.1. I'm the only user with the 8.1 and only synchronize the network of NAS drives. Access the NAS online with the NAS is terribly slow, that sometimes it takes 2 minutes just to access a folder that is not on the first level of training, but at a lower level. I have no idea what kind of question it is. It occurs in two cases during the active sync, and also when I'm 'just' online in the network that is a gigabit ethernet.

  Best regards, Jens

  You have disabled NAS Antivirus service?

• Download of virtual machine using extremely slow browser data store

  Hello

  Why download VM files totalling nearly only 8 GB in vSphere Client v4.1.0 (from 4.1.0 ESXi) via a Gigabit LAN would take more than 1800 minutes (30 hours)? Well now after about 5-10 minutes to download, it is said 1560 minutes but still, why is it so slow? I thought that perhaps is that the estimated time remaining is miscalculated, but this isn't the case. The download is just extremely slow.

  Not only that but vSphere Client (VpxClient.exe) constantly uses 25-45% of my cycles while all CPU's do the downloading of files. This slows down the PC I am running vSphere Client. The local network on the server and the client connections are Gigabit too.

  UPDATE: download time now has increased up to 1924 minutes back and it becomes difficult to use my PC for e-mail in Outlook, etc. because vSphere Client seems to use as many cycles CPU.

  UPDATE 2: 2 hours for download via vSphere Client and remaining time jumped up to 2287 minutes. I'm going to cancel and try to download via the web browser interface.

  See the attached screenshots.

  Thank you

  Derek
