Hyper-V or VHD Backup

The main problem is that to be able to backup a VHD file you need to stop the virtual machine. Now obviously, on mission critical systems you can’t stop a system every time you want to back it up. To overcome this issues, you can us the … Continue reading Hyper-V or VHD Backup

Hyper-V Top Issues

You might remember that Address Resolution Protocol (ARP) has a local cache that prevents broadcasting for a system whose MAC address has been resolved. Older versions of Windows used to have a timeout of 2 minutes for ARP entries (up to 10 minutes), this has changed. Vista and 2008 has lowered this time to a random value between 15 seconds and 45 seconds:
