Description Gurhan Ozen 2010-06-02 23:52:07 UTC

Description of problem:
This was brought to my attention when kvm guests with the latest stable rhel6 tree (RHEL6.0-20100529.n.0 nightly) has failed in beaker. It seems like the installation hangs after loading initrd.img with the message "Probing EDD (edd=off to disable)" .

Providing edd=off to the kernel line works and the installation moves on. 

Just install the guest with the following command:

/usr/sbin/virt-install --name i386_plain_iso --cdrom /var/lib/libvirt/images/rhel6_i386_plain.iso --ram=1024 --vcpus=1 --file-size=10 --hvm --debug --prompt --accelerate --os-variant=virtio26 --network bridge:br0 --noreboot --vnc --file /var/lib/libvirt/images/i386_plain_iso.img 


Version-Release number of selected component (if applicable):
RHEL6.0-20100529.n.0 nightly tree. 
# rpm -qa | egrep "^kernel|^kvm|^qemu"
kernel-firmware-2.6.32-32.el6.noarch
kernel-2.6.32-31.el6.x86_64
kernel-devel-2.6.32-32.el6.x86_64
qemu-img-0.12.1.2-2.68.el6.x86_64
qemu-kvm-0.12.1.2-2.68.el6.x86_64
kernel-headers-2.6.32-32.el6.x86_64
kernel-2.6.32-32.el6.x86_64
kernel-devel-2.6.32-31.el6.x86_64

How reproducible:
Everytime.

Steps to Reproduce:
1./usr/sbin/virt-install --name i386_plain_iso --cdrom /var/lib/libvirt/images/rhel6_i386_plain.iso --ram=1024 --vcpus=1 --file-size=10 --hvm --debug --prompt --accelerate --os-variant=virtio26 --network bridge:br0 --noreboot --vnc --file /var/lib/libvirt/images/i386_plain_iso.img

Actual results:
Hangs when it boots off of boot.iso

Expected results:


Additional info:
providing edd=off in the kernel line works.

Why is that a bug? Probably the virt bios does not support EDD.
