Hi,
E.g. with 32 bridges, and 32 devices behind each one,
the available 64K space gets us only 64 bytes per device.
15 bridges (with io window enabled) max, the smallest io window you can
assign to a bridge is 4k, and you need some space for the devices on the
root bus ...
cheers,

Changes from v1:

- identify device name of new disk by

It does look sane to me too. However, I find this to work only under
virtio_blk. (ide hard drive that qemu has doesn't have the needed
ioctls for hdparm to work)
Amos and Feng, I'll trust that this somehow should pass on non-virtio,
so I won't restrict it to virtio_blk. I made some minor changes

The brief intro:
This patch is created based on the code V4 for block I/O throttling. It mainly
adds a new qmp/hmp command block_set_io_throttle, and enhances query_block(qmp)
and info block(hmp) to display current I/O throttling settings.
Welcome to all kinds of comments from you.
This set is just a rough first pass at avoiding soft lockup warnings when a host
pauses the execution of a guest. A flag is set by the host in the shared page
used for the pvclock when the host goes to stop the guest. When the guest
resumes and detects a soft lockup, this flag is checked and
When a host stops or suspends a VM it will set a flag to show this. The
watchdog will use these functions to determine if a softlockup is real, or the
result of a suspended VM.

A suspended VM can cause spurious soft lockup warnings. To avoid these, the
watchdog now checks if the kernel knows it was stopped by the host and skips
the warning if so.
