Hello
Since quite some time, I'm seeing sporadic I/O errors in guests
running ontop of virtio_blk devices. The information I have is
quite bare: guest usually shows something like:

This patchset had been sent to kvm mailing list few months ago. I suspect they
were ignored. Now I rebased them and resend again.
This patchset removes useless paramter, fixes leak of ioperm data of assigned
device, and fixes double removal of assigned device.

implement kvm_remove_ioperm_data to free ioperm data, and call it
in free_assigned_device to avoid leak.

free_assigned_device removes the assigned device from the
list adev_head, needn't remove it in assigned_dev_update_irqs.

Hi Avi
I just add a comment for kvm_free_assigned_irq(). The other things are all
the same as the patchset you have reviewed.
Applied, thanks.
These would make sense for 2.6.29, right?
I just saw the oops

It is useful to easily grab information about whether or not
we're running on top of a hypervisor. And in case affirmative,
which one.
This patch shows it in /sys/hypervisor (and as a site effect, allow
it to be directly selectable).

This patch is quite close to the last one I've sent.
Only this one goes with chris' suggestion of showing it on
/sys/hypervisor.

KVM has a specific cpuid signature, for a long time now. It's currently
used in the kernel to advertise the possible availability of paravirt
functions, but it's safe to assume that any reasonably recent kvm
hypervisor will sign cpuid this way, regardless of any pv capability.

This patchset creates new commandline arguments -quietboot and
-fastboot
-quietboot silences normal text output from the bios and vgabios. I
rarely care to see this output and it looks much cleaner when the
first thing shown in a KVM window is init or splash (or the dreaded
Windows logo)
-fastboot is implied by -boot -kernel or -quietboot
because if specified, there's no need to show a menu
-quietboot must be explicitly called
