Hi there...
It seems (noted in releasenotes) that F7 should have a VMI (Virtual
Machine Interface) enabled kernel by default, but from what I can find
in the .config files it doesn't... Do I need a special kernel (i.e. only
the XEN kernel has VMI or something) or was it lost in a kernel update
or...?

Could you point me to where it says this in the release notes - I cant see
it.
Cheers

I wrote up the release summary and release notes overview based on what
I saw in the kernel configuration. Looks like a bug that needs to be fixed.

I went ahead and filed Bug #313391 on this issue. Let's see what turns up :)
Thanks a lot for input.

in config-x86-generic:
CONFIG_VIRTUALIZATION=y
CONFIG_VMI=y
CONFIG_LGUEST=m
but it doesn't appear that CONFIG_VMI is enabled on the x86_64 kernel
in config-2.6.23-0.214.rc8.git2.fc8. Unless there's a better answer
shortly, please file this as a bug against the kernel. It may just be
an oversight.
Thanks,
Matt

That's very much like what I'm seeing on i686... Perhaps the configs are
not applied correctly for some reason?!?

paravirt_ops (and thus VMI & LGuedst) only exists on i686. There is no x86_64
or other arch support for any of this yet.

The page http://fedoraproject.org/wiki/F7ReleaseSummary mentions
VMware's VMI. "This release includes the 2.6.21 based kernel which
integrates Kernel-based Virtual Machine (KVM) technology with Fedora's
graphical virt-manager and command-line virsh tools. KVM provides a
hardware accelerated virtualization solution, and users have a choice
between KVM and Xen, along with Qemu, in this release. The kernel
included in this release also has support for VMWare's VMI interface."
I do not find any other mention of VMI on the Wiki or in the release notes.

The bug regarding this,
https://bugzilla.redhat.com/show_bug.cgi?id=313391 has been closed...
Basically it was never in F7, but might make it into F8.

there's overhead with paravirt ops though ;)
at one point it was about 5% even in non-virtual environments... no
idea what it's at now.

According to the paravirt-ops developers, it should be negligable now,
though I admit to not having seen recent numbers on this myself.
