[Bug 784993] [NEW] kvm Guest freeze on boot (guest on own disk, no qemu-image)

[Linuxonlinehelp_de]

Public bug reported:

Binary package hint: kvm

System: AMD64 Server (Phenom 1090T/8GBRAM) upgraded (fresh setup) from
10.04 to 11.04, KVM Guest on own Disk (no qemu-image use)

Bug: On a fresh installed Natty Server with KVM the Guest Systems installed on own Block Device hangs on boot with a Kernel Freeze, Same Guest System (Centos 5 32bit-PAE-Kernel) installed inside qemu-image runs without panic. Guest Boot Parameter not changed (script), after downgrade to 10.04 (fresh minimal-setup + kvm + bridge-utils) works without any errors.
dmesg + logs offers no informations. Test with Debian Squeeze too, NO Errors.

qcow2 Format Problem??
