Public bug reported:

Binary package hint: qemu-kvm

After upgrading my AMD 32bit Ubuntu 9.04 to 9.10, all kvm guests no
longer start up anymore.

The kernel of the host machine is 32 bit linux-image-generic-pae
(formerly known as linux-image-server). Latest update.

A guest is started as:

vdekvm \
  -m 256M \
  -smp 1 \
  -name db \
  -boot c \
  -drive file=/dev/mapper/vg01-kvm2--disk,if=virtio,boot=on \
  -net nic,vlan=0,macaddr=00:16:3e:bf:e6:bc,model=virtio \
  -net vde,vlan=0,sock=/var/run/vde2/vde0.ctl \
  -vnc 10.1.0.1:0 \
  -monitor tcp:127.0.0.1:2023,server,nowait \
  -serial none \
  -parallel none \
  -localtime

The guest starts and boots the kernel. I also can give "break=init" as
cmdline parameter to the guest, which brings me to the busybox. But
after hiting Ctrl+D the guest prints a krenel panic:

Accessing a corruptable shared library.

No frace output

I have a similar setup on an Intel-V based machine completely running
under 64 bit. There are no sch problems. So this must be a bug in 32 bit
mode.

I also tried the linux-image-generic kernel on the host (which limits my
RAM to 3,x GB), but still the same problems. Also installing a 32 bit
kernel in the guest does not solve the problem (I can mount the LVM and
do chrooting-stuff. So do not wonder, if I can install packages in a
guest, which is unable to be started).

Because all 4 guests on the host machine are printing the same error, is
can not be a problem with the guests. At least the "corruptable..."
error seems to be wrong.

This is really a major bug and should be fixed quckly please, because I
am not the only one:

Thanks in advance.
