Block alignment for NetWare 6.5 Virtual Machines

I have an enviornment with multiple virtualized Netware VM's running on vSphere. Some were converted using VMware's P2V software other's were migrated using the SCMT.
My question relates to block alignment at the NSS layer. I have the block alignment handled up to this point:
SAN Luns: 64kb
VMFS Partitions: 64kb
VMDK files: If created using the vSphere client 64kb. If P2V ???
NSS partitions within VMDK: ???
What is the default block size for the NSS partitions in Netware? I there a way to check?
If they are not at 64KB, Is there a tool available to re-align them to 64kb?
Thanks for the help!

The default and only available block size for NSS is 4k. No alignment should be necessary as 4 divides evenly into 64.

How is the performance of Mac Pro if i use it as host for windows and linux virtual machines.

How is the performance of Mac Pro if i use it as host for windows and linux virtual machines.
I am planning to buy a high performance PC to run my Windows and Linux servers as vitrual machines for my testing purposes.
Initially i planned to build my own computer with recommended configurations but considering space constaints and cooling factors i think Mac Pro can be a choice. But need some inputs if Mac pro (Intel Xeon E5, 12 GB RAM) is good for running virtual Machines.

You could even run Windows natively and still run your VM servers.
I have seen reports and such on MacRumors and elsewhere - run Windows natively as well as VMs (can also do testing and run Mavericks in a VM under Mavericks)
The fast internal PCIe-SSD, plus 6 or 8 cores, and 32-64GB RAM. Of course for $5,000 for 8-core, some Thunderbolt storage and 32GB/64GB RAM you can buy some serious hardware.

Blocking Access from Ubuntu 9.04 Virtual Machine

Hi Everyone
We have blocked access on Perimeter Routers for Some specific ports like telnet , SSH etc
and as per access policy users are granted access within the organisation for Servers at Data Centre based on there IP addresses
If some body installs Ubuntu 9.04 Virtual Machine and then invokes virtual XP some how the user gets 10 series IP and still manages to access the servers
How can i block the same
While checking for IP Accounting on Router there are no traces on the Vitual IP but server login details shows the IP address from whcih accessed with source IP as 10.x.x.x

Because your target is a downrev oracle database version you might need to use client compoents like linux 9i to be successful :- [http://www.oracle.com/technology/software/products/oracle9i/htdocs/linuxsoft.html]. The more modern 'instantclient' [http://www.oracle.com/technology/software/tech/oci/instantclient/index.html], [http://www.oracle.com/technology/tech/oci/instantclient/index.html] does not appear available at this verion. Its possilble this version might have issues when installing this version on ubuntu 9.04 ... i simply don't know and too hard for me to look up.
I personally am unaware of any thin client driver technology that would help you here, that isnt to saythere isnt one.
This si not an area i am now current in, i merely really wish to say you do not need a full database install.

Can't install drivers and software for hp c7180 on virtual machine with no USB port

I have a virtual machine running Windows XP to use some old software that isn't compatible with Windows-7. I also would like to print to my HP C7180 all-in-one printer from the XP VM. I downloaded the entire 520MB app and driver package, and then just the 72MB driver package, but both give me errors stating:
This system does not meet one or more of the minimum requirements needed to install this product. The installation cannot continue.
Requirement/Details and Guidance
USB Drivers/This computer does not have the necessary USB software support to allow completion of a USB installation. The installation cannot continue until this is resolved.
USB Hardware/Required Action: Click Cancel to exit this software installation. In order to install this device as a USB device, please refer to your computer documentation or USB add-in card documentation for more information about USB drivers.
I don't want to do a USB installation, but a Network installation as this all-in-one is connected only to my network.
Is there any way to force this software (with an option/switch) to only do a network installation? It never gets to the part where it asks what type of install where you can choose USB or Through the Network.
A link to where I can simply download the drivers that would allow me to print only would work as I can create a local LPR printer port using the printer's IP address.
Please advise...

Question on potential configurations for resource cluster as virtual machine server / beowulf / render farm

I am looking for a starting point on where to focus my efforts in researching a desired configuration. Of course anyone who spends anytime researching in forums knows that one thing that people hate is for people
to ask questions that can be easily answered with a simple Google search, so let me start by saying I have done many hours of research on this already. The problem I am having is that although there is a huge amount of information out there on what I
am looking to do, I don't believe many people have attempted this on as small of a scale as a single user system. Also, the amount of routes to go down seems endless, which for me so far has led to many hours of wasted trial and error. So keep
in mind that I am not so much looking for a handout on answers but rather a more narrowed path of searching and researching.
What I am looking to do is take the current equipment that I have and consolidate it into a 9-12U server rack using mounted 2 or 3U atx cases so that I can have a more organized, space saving setup. That is the
easy part, what I have been looking into though is the combining of cores and processing power to make a "super computer" yet I use this term very loosely. From what I have read, the closest thing I can compare the idea in my head to is referred
to as a Beowulf Cluster, or a Render farm but I believe as the name suggests that this is more dedicated to a single task of rendering. I like the idea of a virtual machine server where I would never actually locally use this machine but rather set up
many virtual machines that I can remote into. I started to compile a ProxMox Server, and this was the right idea, however when running a VM, that VM is constrained to the hardware resources of the single node that it is assigned to. If there is
a way to be able to have a machine that would utilize the 20 some odd cores that I would have in the cluster, along with the 40-50 gigs of ram, well that would be ideal but sounds too good to be possible. Also, ProxMox isnt quite there in compatibility for
a home/home office user. I understand that the programs that are used have to be written in a way where the architecture allows for such, but if it could even be used for speeding up my render time with Adobe and Autodesk (which I know do have such functionality)
that would be wonderful.
So without writing a whole book I am looking for suggestions on how to proceed. Can I literally build a "super computer" that is not really that super... more mediocre super... or am I better off just consolidating the hardware but not the
OS's and programs. Also, I do currently use three or four different distros of Linux, mostly for ethical hacking and security type work like pen testing. One thing I have never been a fan of though is dual booting. Perhaps investing
in a hot-swap HDD chassis that I could load all the different OS's on where I could just pop in whatever OS I am looking to use. As you can see I am far from knowing where to spend my efforts in research.... THANK YOu for ANY help.

THANK YOU AGAIN TO ANYONE WHO HAS MADE IT THIS FAR in reading this.

The cluster works only for standalone webcache and httpserver installations types.
If you want to do this you have to use dcmctl command to change from one farm to another.
try checking with dcmctl command with out options an dyou will get a full list of options.
then run dcmctl usage(orhelp) option to see what you need.
As far as I remember
you have to check the farm id of the server you want to be the master
then in the second, you have to run dcmctl joinfarm or something like that.
Regards.

Set a delay for automatic shutdown of virtual machines

Hallo,
is there a way to set a delay for the automatic shutdown of the guests when the host is shutting down? Just like the automatic startup delay but for the shutdown. The simplest possibility would be to shutdown the guest in the opposite of the startup delay.
I want to shutdown the Exchange Server first and then the rest - the virtual Domain Controller should be shutdown as the last server.

Hi,
Additional, please notice the guest 5 minutes delay shutdown issue, more detail please refer the following article:

Monitor bandwidth utilization for Hyper-V's Virtual Machines

Hi,
I'm wondering, if SCOM is capable to monitor incoming & outgoing traffic (current and total over time) of VMs in Hyper-V?
Tried to search about it, and found only 3rd party tools or the monitoring is only available for Router, not VMs.
Thanks.

Hi Andre,
Also you can use performance monitor to monitor the VM's bandwidth through counter "Bytes Received/sec" and "Bytes Sent/sec" under Hyper-v virtual network adapter :

Virtual Machine Additions in Virtual PC for Mac 7.0.2

I'm also new to Virtual PC for Mac and will try some of the suggestions for speeding it up; it is painfully slow. However, I have another but related question.
I keep getting a prompt when I boot Windows XP Prof. and it opens Virtual. It tells me that after I see my Windows desktop, I should install and update Virtual Machine Additions from the PC Menu. My problem is, I can't figure out how to do that. When I'm in Windows, I've explored everything I can find......Menu...Control Panel...Applications, but I can't find anything that shows Virtual PC running so I can't get to the menu that should take me to updates. When I open just Virtual from my Mac desktop (w/o opening Windows) it checks for updates on Virtual PC for Mac but not Virtual Machine Updates. Neither can I find anything on Machine Updates when I search Apple or this support site. When I search Yahoo, it says I have to be running it to update....kind of full circle with it.
Can anyone help re: how to do Virtual Machine Addition Updates? Thanks.

Oops...tried it again..new problem. When I open Virtual, this is the message I get. When I boot from Windows it works........
"OS not found
Install an OS on this hard drive
Reboot and Select proper Boot device
or Insert Boot Media in selected Boot device"
Think I'll uninstall and re-install e'thing from the Virtuall PC for Mac CD. Hate to do it.......just spent a long time y'day doing 17 security updates.
Maybe reinstalling I'll be able to do Machine updates.
Thanks for the help.

What is account for logon for first Azure virtual machine?

I selected build a server farm, but I don't remembering any input for administrator account. How do I setup administrator account for my first Azure virtual machine after it was automagically built as part of a server farm option?

I am assuming you are talking about SharePoint server farm.
After you select New->SharePoint Server Farm, Azure asks you to type in the resource name and then it asks you for usernames and passwords for each virtual machines local administrator. These are the usernames which you use to access these machines.

Forgot Azure Virtual Machine Password

Hi Team,
I have forgot the Azure VM password and unable to connect the machine through RDP. Please help me so that I can connect with my VM. This is an urgent issue please help me. Thanks in Advance.

Hi,
You can follow these steps to reset the existing built-in local Admin credentials on Microsoft Azure virtual machines using Windows PowerShell and the Microsoft Azure PowerShell Module. Note that this process will also ensure that Remote Desktop is enabled
within the Microsoft Azure VM.
>>In the Windows PowerShell ISE window, run the following PowerShell cmdlet to confirm the name of your Microsoft Azure subscriptions (if you have more than one subscription).
Get-AzureSubscription | Format-Table –Property SubscriptionName
You’ll be specifying the name of your selected subscription in the next step.
>>In the Windows PowerShell ISE window, run the following PowerShell cmdlets to select your Microsoft Azure subscription (if you have more than one subscription).
$subscription = “ENTER YOUR SUBSCRIPTION NAME HERE”
Select-AzureSubscription –Default $subscription
>>In the Windows PowerShell ISE window, run the following snippet to prompt for the credentials to which you’d like to reset the existing built-in local Admin user account inside the virtual machine.
$adminCredentials = Get-Credential -Message "Enter new Admin credentials"
If the existing built-in local Admin username is input, the snippet below will reset that account to use the specified password. If a new username is input, the snippet below will also rename the existing built-in local Admin account to match the specified
username.
The password that is input when prompted above must meet password complexity requirements of at least 3 of the following: 1 UPPER case letter, 1 lower case letter, 1 number and/or 1 symbol. Note that if the password does not meet complexity requirements,
the snippet below will still succeed - the password complexity requirements are not checked until after the VM restarts and the VM Agent is leveraged to apply the new password.
>>In the Windows PowerShell ISE window, run the snippet below to reset the built-in local Admin credentials for the selected Azure virtual machines.
(Get-AzureVM) |
Where-Object -Property Status -EQ "ReadyRole" |
Select-Object -Property Name, ServiceName |
Out-GridView -Title "Select a VM …" -PassThru |
ForEach-Object {
$VM = Get-AzureVM -Name $_.Name -ServiceName $_.ServiceName
If ($VM.VM.ProvisionGuestAgent) {
Set-AzureVMAccessExtension -VM $VM `
-UserName $adminCredentials.UserName `
-Password $adminCredentials.GetNetworkCredential().Password `
-ReferenceName "VMAccessAgent" |
Update-AzureVM
Restart-AzureVM -ServiceName $VM.ServiceName -Name $VM.Name
} else {
Write-Output "$($VM.Name): VM Agent Not Installed"
Let’s look at each line from the snippet above in a bit more detail …
First, Get-AzureVM is used to enumerate the existing VM’s that are provisioned in the selected Microsoft Azure subscription. We can only reset the built-in local Admin credentials on Running VM’s, so we pass this output to a Where-Object filter to return just
the list of VM’s that are currently in a ReadyRole state.
We pipe this filtered list of running VM’s to the Out-GridView cmdlet. This cmdlet prompts to select the VM’s for which the built-in local Admin credentials should be reset.
Finally, the selected VM’s are piped into a ForEach-Object block that resets the built-in local Admin credentials for each selected VM using the Set-AzureVMAccessExtension cmdlet. This block also restarts each selected VM using the Restart-AzureVM cmdlet, so
that this change is processed.
Hope this helps !

Sowmya

Error while booting a virtual machine

Hello,
I have a problem when I try to boot a virtual machine in the web interface :
"Error changing desktop state: com.sun.vda.service.api.ServiceException: No suitable hosts to start a desktop for Desktop Provider gorilla.cscs.wmin.ac.uk."
So, I created a pool for my desktop assigned to a desktop provider, then I created a group assigned to my pool, I imported a desktop from the "desktop" tab of the pool menu without problems and when I want to start the machine I get this error.
Have you got any ideas ?
Have a nice day.
PS : Sorry for my english, I am french :)
Edit : now a different error :

Keep in mind of the following:
ZFS uses any memory available (up to the limit) for a so-called ARC cache. This can cause issues in a demo setup, because VDI may falsely report that there is not enough memory for starting up any virtual machine. To resolve this issue, adapt the max value used for the ARC cache.
For example, to restrict the memory to 2GB, add the following line in /etc/system:
set zfs:zfs_arc_max = 2147483648(Text copied from: [VDI Demo (Featuring Sun VirtualBox)|http://wikis.sun.com/display/VDI3dot1/VDI+Demo+%28Featuring+Sun+VirtualBox%29] )

Installing Acrobat 9 Pro on a virtual machine on my Mac using Parallels. Not an upgrade but being asked what I upgraded from.

I'm installing Acrobat 9 Pro for Windows on a virtual machine on my Mac (running Parallels). I successfully installed the same program using the same discs on the same Mac previously, but that virtual machine became corrupt and can no longer be launched. For this re-installation, the installation sequence is asking what version I upgraded from - but as this is not an upgrade, I get stuck at that step and am unable to complete the installation. What should my next step be?

Hi Akselowner,
This error usually comes up if the serial number you are using is an Upgrade serial number.
In such a case the installer will prompt to enter the previous qualifying version serial number.
Please send me a private message with the serial number and I will validate and confirm that for you.
If you do not have the previous qualifying version serial number then the current serial number needs to be unlocked.
Please contact our customer service so that they can do the needful for you. You can even reach our chat support at http://adobe.ly/yxj0t6
