Today we are going over a script I wrote to utilize the ovmcli to rename all virtual disks to follow a understandable standard, in this case we will take the vmname and append a disk identifier to it. The first disk (slot 0) will be appended with “_system.img” with all subsequent being appended with “_dataX.img” […]
So I have been working with the OVM CLI lately to try and fill in some holes in my knowledge and provide for some easily reproducible procedures, usually around consistency of the environment when performing frequent tear downs and upgrades. So expect to see more OVM related scripts going forward. Today we are going over […]
In my laptop I have a solid state disk, and frankly I am way past addicted to solid state disks, but what you get in performance you lose in capacity. As such I have had to be creative with how I can have the capacity and the performance that I need. Lately the solution has […]
When you compare Linux-KVM to Hyper-V or VMWare your initial results will indicate that Linux-KVM is lacking when it comes to management tools, and basic functionality. You would be correct, however you would also be incorrect. You see with Linux-KVM we can leverage the underlying power of the Linux userland, and with this frankly all […]
When using a Core version of Hyper-V 2008 R2, be it Hyper-V Server 2008 R2 or Windows Server 2008 R2 Standard Core, you are doing a good thing to conserve resources and minimize the attack footprint of your virtualization hosts. However this comes at a price. One of the most obvious misses in this matter is the enabling of Jumbo Frames on the Virtual Switch Interface. This enables your guests to reach out to storage directly using jumbo frames (mtu size of greater than 1500 bytes – however in this article we will be working specifically with 9000 bytes).
