    Putty (plink) and unknown host key

    Byetzion 17/04/2011

    Putty has announced that they will not allow automatic import of host key. You should press the damn ‘y’ yourself, or else, you will fail. A quote from their FAQ says: “A.2.9 Is there an option to turn off the annoying host key prompts? No, there isn’t. And there won’t be. Even if you write…

    Don’t try it at home – NetApp SnapMirror network-free Seeding

    Byetzion 26/05/2010

    Well, this is rather common. Network-free seeding is being performed through using a tape device. What happens if you do not have a tape device? We have the poor-man’s huge TB disks (SATA for the people) connected to simple PC systems, but no tape… We perform network-free seeding into disk. There is a utility called…

    Oracle VM post-install check list

    Byetzion 22/05/2010

    Following my experience with OracleVM, I am adding my post-install steps for your pleasure. These steps are not mandatory, by design, but will help you get up and running faster and easier. These steps are relevant to Oracle VM 2.2, but might work for older (and newer) versions as well. Define bonding You should read…

    Citrix XenServer and DR

    Byetzion 16/05/2010

    Assuming your storage is capable of replication, a bunch of VMs could be happily replicated to an alternate location, where you can start them on will (and on crisis, most likely). This procedure, in theory, is rather simple. I have discovered that it is less so, especially if your system goes into testing once a…

    Oracle VM and network bonding

    Byetzion 09/05/201011/07/2015

    Oracle VM, out of the box, does not allow network bonds. An excellent guide on how to enable bonding which I have partially followed, has convinced me that changing the relevant scripts would be better. That I have done, and reported in this wiki post. To sum things up – configure bonding/VLAN tagging as you…

    After a very long absence, Changing Linux HVM to PV on Xen

    Byetzion 08/05/2010

    I have had a stressed time, and had no time to actually write down anything here. This is pity, since I have been doing so many things worth sharing. I will start with a small one now – how to convert a physical machine into Xen-based VM. I assume you know the drill of how…
