Performance, Private Memory Limit and Virtual Memory Limit

Private memory limit uses your system RAM, where the Virtual Memory limit will use Disk drive space. In most cases it is best to only set a private memory limit to prevent degradation to system performance if an application starts to use excessive amount of memory. Many .Net application will use large amount of virtual memory(Drive Space).

 

How to limit IP assignments to a guest OS and setup IP security using ACLs on Hyper-V Server

Limiting the use of IPs by each Guest OS is an important step in securing your network from accidental or intentional abuse of IP resources. 

You can limit IPs in Hyper-V 2012 using ACL rules much like any router or managed switch would provide via ACLs.

No Gui is currently available to manage ACLs so you will need to open Windows Powershell if you are in GUI mode. Lets assume you have VM named "Poject1" and you would like to limit this client/gues VM so they can only use 10.0.0.75 as an IP address.

 

Here are the commands:

 Add-VMNetworkAdapterAcl -VMName Project1 -LocalIPAddress 10.0.0.75 -Direction Both -Action Allow

 Add-VMNetworkAdapterAcl -VMName Project1 -LocalIPAddress any -Direction Both -Action Deny

That is it, your done.

 

Now you can check the rules with:

 Get-VMNetworkAdapterAcl -VMName Project1

 

or you can remove the rules using:

 Remove-VMNetworkAdapterAcl -VMName Project1 -LocalIPAddress 10.0.0.75 -Direction Both -Action Allow

 Remove-VMNetworkAdapterAcl -VMName Project1 -LocalIPAddress any -Direction Both -Action Deny

Windows is unable to install to the selected location. Error: 0x80300001

This error occurs when the installer cannot find the install image, this commonly happens when you install f6 drivers but then forget to put the windows install disk back in the drive. 

  • Verify that you have placed the install disk back in the same drive you had it in to start the install process
  • Verify you are using the correct drivers (windows version, 32/64bit)

Problem should be resolved at this point.

How to Claim or Publish your Yahoo local listing,

You would think this would be a simple 3 step process like bing or google however, following the instructions laid out by Yahoo! will bring you to one of several pages.

 

Claim Listing:

Following the claim listing instructions lands you on this page:

https://smallbusiness.yahoo.com/merchantsubmit/claimlisting

Which errors out with a partially rendered error page.

 

Create listing:

Following the create listing instructions lands you on this page:

https://smallbusiness.yahoo.com/dashboard/v2/apps/mylisting?bizid=##########

This page also loads a partially rendered error page in the inner window.

 

Solution:

You can simply go to https://smallbusiness.yahoo.com/dashboard/mybusinesses to manage your business listings without issues.

 

Thoughts:

Why a large company like yahoo has such poor documentation on something so simple is beyond me. If someone from Yahoo! reads this please update your documentation and make use of some 301 redirects for all of these old non functioning business listing management pages.
