Hi,
I tried executing QEMU (realview-smp ARM11MPCore) with Linux kernel 2.6.39.3,

Please send in any agenda items you are interested in covering.
Thanks, Juan.
I am investigating how QEMU block devices are emulated. It seems that qemu

In general, we have seen that during a reboot of a
running guest (by issuing a 'reboot' command in the
guest), the guest goes down normally, but when coming
back up, during the udev phase, it takes anywhere from
a few seconds to a few hours to complete that part of the

In some situations might be useful to let qemu use an image that was
prepared for a live snapshot.
The advantage is that creating the snapshot file outside of the qemu
process we can use the whole range of options provided by the format
(eg for qcow2: encryption, cluster_size and preallocation).
