This is a new version of the rbd driver. The only difference from v8 is
a check for a recent librados version in configure. If the librados version
is too old, rbd support will be disabled.

In certain use-cases, we want to allocate guests fixed time slices where idle

this but the most direct is to simply avoid trapping the HLT instruction which

Humm,
unfortunately I'm not a developer, only a sys admin, but this would
be a nice feature to avoid restarting vm guests.
I didn't want, but I think I will have to add another
software layer (LVM) inside the guest vm.
This way, when I need more space, I hot-add another device and
add it to the v

Hello,
The first patch adds an lseek test. The second one is just a mirror corrections
of critical flags for some of the smoke_test subtests.
The lseek test do what is expected. The result of lseek on
virtconsole/virtserialport should be -ESPIPE or err 29 in python.
Regards,
Lukáš

Hi guys,
I have a KVM guest machine, lets name it VMTEST,
using an iSCSI LUN as a virtio device. Something like this:
On iSCSI server, if I resize this LUN, this resize is detected
on KVM host, but not on the VMTEST. The device resize is only
detected if I restart VMTEST. Is the
