the best about samba: thanks for samba, it provides users with a fast (of course depends also on harddisk speed) rock-solid no-limit-to-maximum-users file-server for maximum file-transfer-and-sharing-and-storage productivity (and they will USE that T: temp drive for EVERYTHING! prepare for TERRABYTES […]
usually it works like this… the user sets upa Template (like basic WindowsXXX or Linux installation) and clone this template for various purposes (spezialize on…). in KVM it looks like this: su – root virt-clone –connect=qemu:///system –original CloneThisVM –name NameOfClone […]

You can not have VirtualBox and KVM running on the same host at once. If you want to do Android App development on Linux (which uses KVM for running the Emulator) then you have a problem 😀 KVM seems to […]
This video was published on Sep 13, 2012… I/O-Wise KVM does not seem to do a lot of RAM-Caching… VirtualBox does? dd shurely runs a lot faster on VirtualBox 😀 KVM does some impressive GPU-Pass-Through: Gaming on a Linux host […]
Virtualization is a must, if you want to have 50x mail servers, 20x windows servers and 10x linux servers on the same machine 😉 meaning: if your requirements reach a certain complexity, you will not be able to get all […]
