Hello, Given that most well known VPS providers such as Slicehost, Linode etc are all using Xen instead of other technologies such as KVM, what are the unique advantages in your opinion? Performance? Stability? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] Advantages in using Xen for VPS platform
Hi! Security, isolation, performance AND stability! :-D My KVM host at my Dell Desktop already freezes two times, I mean, my four guests died, requiring a reboot... I''m on Ubuntu 9.10. Now I have the Xen 4.0 with Linux 2.6.32.9 (pvops dom0) on top of my Ubuntu 9.10 working with Compiz and support for PVM and HVM domains...

Re: [Xen-users] Advantages in using Xen for VPS platform
Try to connect via virsh (Libvirt 0.7.0) to Xen.
When you will done with this.
Try to run:-
# virsh create OSOL134.xml
or just try to create Xen guest via virsh. At this point you gonna realize that
the picture you''ve wrote is not so nice as it seems at the first
glimpse.
Virt-install will reject creating HVM guests only PV at the same time.
Actually, you are supposed to work via "xm" profiling for DomU
management.
( vs F12 with same Xen-4.0-rc6&(2.6.32.10 pvops) on the top )
It doesn''t mean that i like KVM, however Libvirt 0.7.X-Y is not quite
ready
for Xen 4.0 for obvious reasons on both F12 and U 9.10 Server ;)
Boris.

Stability? >Xen has been around for much longer than KVM, and Xen is known to be very stable (if you''re running the correct/good versions). Also Xen is a type 1 baremetal hypervisor, providing better security and isolation than KVM. KVM is a type 2 hosted hypervisor (loadable kernel module for Linux). -- Pasi _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
