hm,
without digging deeper into the theme, I assume you cannot nice or
schedule the KVM machine, as it is implemented in the kernel. So I would
add a CPU-consumption DoS, as kernel-mode execution has high prio.
And, as things like scanner and audio have own groups, it makes sense to
give a

Ubuntu policy is that assigning of custom groups to device nodes should
be done by rules shipped with the package that creates that group, in
this case KVM.

Hello Scott,
then why did you change the bug report to invalid? The only thing that
needs to be corrected is, replaung the patch with a own udev rule file.
Everything else discussed here, is absolutely correct.
The title of the bugs reads: access to /dev/kvm should have a
different
As I noted, the udev portion is invalid because it is not Ubuntu policy
to apply custom groups in the udev package; this should be done in the
kvm package -- and you'll note that task in the bug is left confirmed

Well,
this bug ( #127704 ) is a bug filed to the kvm package, not the udev
package. So it's still the right place. Only the patch is invalid, which
is no problem: As one of the foreposters noted, there already was such a
udev rule file, provided by the kvm package. So we should simply look
In the old (feisty) package I found in kvm_16-1ubuntu2.diff:
--- kvm-16.orig/debian/kvm.udev
+++ kvm-16/debian/kvm.udev
@@ -0,0 +1 @@
+KERNEL==kvm, NAME=%k, GROUP=kvm, MODE=0660
That patche the orig. sources and inserts the udev rule file via .deb
package. Indeed a nice apprioach, until now I

I already mailed the diff, that is needed to create a udev rule within
the kvm package.
Scott please re-confirm
I'll re-add the udev rule to Gutsy's KVM package.

The only harm in allowing normal users to access /dev/kvm is a potential
memory DoS until guest swapping is implemented. I suggest that a
special group be made until that feature is implemented.

This is already done by the kvm package, and has been for some time (In
the file /etc/udev/rules.d/50-kvm.rules). How did you install KVM? I
wonder why your kvm device is not getting the correct permissions.

I installed KVM by executing

This would be a rather useful change. Right now only root can use kvm,
which is sort of besides the point.
