Red Hat buys Qumranet
After seeing another virtualization.info feed in my inbox, I was going through it leisurely just glancing through the topics and I came across a news line which read “Red Hat acquires Qumranet, suddenly becoming a key virtualization player” and I sprang to my feet with surprise.

NFS support for BtrFS
For the uninitiated, Btrfs is a new copy on write filesystem for Linux aimed at implementing advanced features while focusing on fault tolerance, repair and easy administration. Initially developed by Oracle, Btrfs is licensed under the GPL and open for contribution from anyone. My interest in it lies in BtrFS being a very good competitor [...]

I had dropped plans to buy this cool Open Source Linux phone, Open Moko, because of the hassles involved in shipping from a foreign country and others. But I was told by a friend, that we have a dealer in India, Ida Systems. Now I’ve changed my decision. I’m going to buy it [...]

XEN vs KVM
I’ve been running some benchmarks on KVM and XEN of late and here are some views on it. Remember we are comparing XEN pv vs KVM. But there is nothing wrong in it, as we should choose the best of both to compare them truly.

RedHat has been a major contributor to XEN from early days. But in around [...]

Just now I read an email in my btrfs mailing list about the opensourcing (GPL v2), by HP, of their filesystem ADVFS. Its very interesting to see what will be oracle’s response to this. Will they ever think that this btrfs venture is a waste ? I’m not terribly sure what would be running in [...]

I was frustrated the other day when linux-2.6.18-xen running off XEN did not detect my Intel Pro/1000 PCI Express Gigabit Ethernet card, abbrivated as e1000e. The PCIe version of e1000 was not supported yet. I even decided to get a new e1000 PCI for its mistake.
I tried a lot in making it get detected. But [...]
Using qcow for your disk images
For the uninitiated, CoW stands for Copy on Write. Suppose you have to make two copies of something, creating a full copy could be expensive. So, what you do is, when you do a copy, just share the contents. When you modify one of the copies, only then a copy – Copy on Write. So, [...]
