2. Update according to the comments of Alex and Michael.

Hi, my question is whether it is possible with KVM
to duplicate a running VM. I can save the guest,
copy the raw LVM (or a snapshot), but how do I
restore it under another name. And with disabled
networking (pull cable)?
Is that possible?
PS: Just
This series makes an attempt to make kvm-unit-tests more friendly to upstream
QEMU. I've been writing unit tests for all of the QMP commands and many of
them, like ballooning, require guest cooperation to be tested in a meaningful
way.
I'm leaning towards building simple guests using libcflat in
I'm not sure if this was intentional but the QEMU i8259 does not support this
flag. I haven't observed any issues with this but I'll happily admit that
I'm not very aware of what I'm doing here.

This unconditionally switches to use the serial port but tries to use the
