Notes:
If you use the modules bundled with kvm-86, you can use any version
of Linux from 2.6.16 upwards. You may also use kvm-86 userspace with the kvm modules provided by Linux 2.6.25 or above. Some features may only be available in newer releases.

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.

it doesn't compile on rhel/centos-5.3 because of this error:

You need to enable mmu_notifiers in your target kernel (looks like 2.6.29-rc6).

We double-checked and it is enabled in the target kernel.

Hmm, grep MMU_NOTIFIER /lib/modules/2.6.29-rc6/build/.config

Hi,

I'm not having any luck getting my usb thumb drive recognized in my Windows guests via the hot plug method. I checked the wiki site and it looks like this is an issue being worked on - does anyone know the status of this? (I can get it to work by creating an img file for it.)

Regards,
Cindy

Are you using usb hot plug or scsi hot plug? What exactly are you doing?

error compiling committee.c: too many arguments to function

I've tried adding it as 'pcidevice host=<bdf>' when launch the guest and via hotplug w/ pci_add pci_addr=auto host host=<bdf> after the guest is launched.

Can you try it with a Linux guest? Might be easier to debug.

Look at /proc/interrupts to see if guest interrupts are received.

Can you post your config-host.mak and config-host.h?
