Re: [Xen-users] Why HVM?
Hi Jonathan,
The only big advantage is that customers can install operating
systems that do not support pv operation (e.g. Windows). Some small
advantages like using own GRUB or kernels can be achieved in pv
environment, too (pvgrub, pygrub), but those hosters probably don't
enable that for pv VPS.
Another little point is that not all HVM features are available for
pv guests, especially with pv_ops guest and host kernels (for
example: USB passthrough, PCI / VGA passthrough; the first two not
yet with pv_ops kernels, VGA passthrough is always only available
for HVMs). But as long as you don't want to offer physical hardware
to your clients, this doesn't matter for VPS hosting.
Probably I missed an important point, but AFAIK there is no
advantage of having a Linux server system in a HVM instead of a PV
VM.

Hi Everyone,
I've noticed some VPS hosting companies offering a Xen "HVM"
option.
What are the advantages of a Linux HVM VPS over a PV one?
Many Thanks
