Hello everyone, Im starting to use Xen on a SUSE Linux Enterprise Server 10 SP2, but Im not quite happy yet with the virtual disk management. I still need to do a lot of research about that, but first I want to ask the community about a simple way to handle the guest machine disks. *Is there any way to increase/decrease a guest machine disk after the OS is installed? Can I have a dynamically

I am experimenting with KVM and I wish to create a virtual machine image in a logical volume. I can create the new lv without problem but when I go to format its file system then I get these warnings: Warning: WARNING: the kernel failed to re-read the partition table on /dev/sda (Device or resource busy). As a result, it may not reflect all of your changes until after reboot. Warning: Unable to

The following patches introduce support for multipath and cciss devices to the ovirt-node and node-image. Comments are appreciated. These patches assume that the 3 patches (2 node, 1 node-image) from Joey are all incorporated. Mike

Btrfs has been broken for me for ages. I first reported it on this list 5 months ago[1].
