Just to give me 50 cents, Proxmox uses full KVM virt, they offer their own GUI and storage management on top of standard QEMU/KVM.

However seems nice and fully featured. The pity is that is based o KVM, which is as far as I know is a ligth hypervisor that is not able to isolate the virtual machine properly. Due to this is possible to frozen the hypervisor kernel from a guest virtual machine allowing somebody to freeze all your VMs all in once. Xen is completly isolated (of course not as light as KVM). You can freeze a VMs but other could not be affected in anyway. Security should not considered an option. Thanks anyway, Max Il 25/02/2017 14:02, Brian : ha scritto: Hi Max, Have you considered Proxmox at all? Nicely integrates with Ceph storage. I moved from Xenserver longtime ago and have no regrets.

Xenserver is a linux distribution based on CentOS. You cannot recompile the kernel by your-own (... well, you can do, but it's not a good idea). And you should not install rpm by your-own (... but, i'm gonna do this). Then I'm stuck with some plugin and just some rpm compatible with kernel 3.10.0-514.6.1.el7.x86_64 However I found a way to install more or less the Ceph Client. I have forked the plugin of https://github.com/rposudnevskiy/RBDSR It seems the most update. Here you can find my findings and updates: https://github.com/phoenixweb/RBDSR However at the moment I'm stuck with a kernel unsupported feature. :( Let's see if I can let this work.

At this point there are only some self-made plugin and solution around. Here some: * https://github.com/rposudnevskiy/RBDSR * https://github.com/mstarikov/rbdsr * https://github.com/FlorianHeigl/xen-ceph-rbd Nobody know how much they are compatible or if they are gonna to break Xen the next update. The ugly truth is that XEN is not still able to fully support Ceph and we can only pray that one of the plugin above will not destroy our precious data or VDI. Does anybody had some experience with the plugin above? Which one you'll reccomend? Is there any good installation guide to let this work correctly? Can I just install Ceph with ceph-deploy or do I have to unlock repos on the xenserver and instal it manuall, Thanks for any kind of support. Attaching volumes from openstack portal (or using cinder volume manager), has been working fine since 6 months ago, but I do not know what will happen on next updates Regards, Max _______________________________________________ ceph-users mailing list [email protected]<mailto:[email protected]> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list [email protected]<mailto:[email protected]> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list [email protected]<mailto:[email protected]> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list [email protected]<mailto:[email protected]> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
