Rusty, this patch exploits the new function virtio_break_device() as of your patch set dated January 15th on linux-kernel at vger.kernel.org. The patch avoids hang situations during device unregister, when a (block) device with active IO is hot-unplugged.

Hi, here is my v4 patch-set update to the v3 RFC submitted on Nov 27th. When an active virtio block device is hot-unplugged from a KVM guest, affected guest user applications are not aware of any errors that occur due to the lost device. This patch-set adds code to avoid further request queueing when a lost block device is detected, resulting in appropriate error info. Additionally a potential

This patchset tries to go towards implementing both virtio-1 compliant and transitional virtio drivers in Linux. Branch available at git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux virtio-1 This is based on some old patches by Rusty to handle extended feature bits and endianness conversions. Thomas implemented the new virtio-ccw transport revision command, and I hacked up some
