[Xen-users] XCP eccentric, "embedded" install on small system disks
Hello, I really like the features of XCP, and it seems very accomodating in hardware compatibility as well - quite differently from vSphere... I would really like to use it as the hypervisor for my home fileserver... The only problem is that the fileserver has a 4 Gig solid state CF card and a 6 Gig microdrive for system purposes, the rest of the storage (2 x 1.5 Tb SATA) is already formatted into a mirrored ZFS zpool, and I''d really like to avoid having to break that up. Of course, I get the "no hard disks with sufficient space" message. (I disconnected the data disks before install.) So I was wondering, since XCP is open source and all, if there is an advanced, manual option (even if it has to do with digging into the heart of the system) to install it on such a small, embedded environment. I''m quite certain I don''t need the 2x4G management space, I''ll be running two virtual machines AT MOST, virtualization is mostly to simplify remote management, and allow for GUI (without X11 forwarding) on a headless machine. In an ideal world, the setup would look like this: 4G CF card: hypervisor boot partition and configuration (semi-static, definitely no swapping or other frequent writes) 6G microdrive: VM images and swap 2x1.5T data disks: transparently linked to a Linux or OpenSolaris VM, which will handle the ZFS zpool Does this sound possible? I''m ready to get my hands dirty in configuration and code, I''m a Gentoo veteran... XD Thanks, Daniel _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

If you are ready to do some experimenting I would suggest, to take a look at Project Kronos (http://blog.xen.org/index.php/2011/07/22/project-kronos/) Regards Geza _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
