Hi,
I've tried booting two VMs (Ubuntu and Fedora 11) that previously
worked with the latest kvm-userspace. At start, I get the following
warning:
Could not open '/dev/kqemu' - QEMU acceleration layer not activated:
No such file or directory
But, booting proceeds quickly which seems to indicate that KVM is
being used. However, the network device is not started and the
graphics don't start properly. CPU usage also spikes to 100% and
stays there and I can't interact at all with the VM. I'm running
the 2.6.29 KVM kernel in the guests.

As a simpler test, I tried booting the fedora 10 installer.
Similar to
my existing VMs, it boots, but when it tries to launch the display, it
hangs and 100% cpu usage occurs. I tried with the std, vmware and
cirrus vga adapters and the same thing happened each time. Although
with cirrus the CPU usage isn't as high, but it still hangs.

I also met the same problem with 2.6.30-rc3. Guest can not get IP and qemu process cpu utilization is always ~100%.
Well, I don't get the X display problem with -no-kvm. It's only X
that's the problem, terminal output and curses work.
As far as networking goes, I've had success getting the network up with
VDE on one machine, but not with bridged networking. Even running with
-no-kvm doesn't help. But, I have no problems with the lastest Qemu.
So there's something in qemu-kvm that is causing the network problems
that even -no-kvm doesn't fix.
