Hello,

Is renaming qcow2 images prohibited?
My VM behaves differently (hangs when boot is complete) after copying the image.
sudo taskset 3 /usr/bin/kvm -m 1024 -hda test2-deb32-net.qcow -net
nic,model=rtl8139,macaddr=52:54:00:00:00:15 -net

I have a question on guest smp performance. If I have a host with core 2
duo, should a kvm guest perform better using -smp 2 as opposed to not using
-smp 2?

These helper routines supply most of the virtqueue_ops for hypervisors
which want to use a ring for virtio. Unlike the previous lguest
implementation:
1) The rings are variable sized (2^n-1 elements).
2) They have an unfortunate limit of 65535 bytes per sg element.
3) The page numbers are always

This is an hvc-based virtio console driver. It's suboptimal becuase
hvc expects to have raw access to interrupts and virtio doesn't assume
that, so it currently polls.
There are two solutions: expose hvc's "kick" interface, or wean off hvc.

The block driver uses scatter-gather lists with sg[0] being the

This issue appears with commit 091b206f6c56f2329e11bac2fa40d6f236ab0bc2
because before it, the decoding was done internally to kvm and after it
is done by x86_emulate.c (which doesn't do it correctly).

The new kvm_para.h header file added by (I think) this change isn't
installed by "make install", making builds using the libkvm installed on
the system fail.
