Virtual machine got stuck during boot - "Probing EDD"

[Pavel Műller]

Hello,

I found the way how to install various OS in ganeti on this website:
https://code.osuosl.org/projects/ganeti-image/wiki/HOWTO_-_Ganeti_Instance_Image

I downloaded and installed the package "ganeti-instance-image_0.5.1-1_all.deb". After that, I performed the following configuration:

/etc/default/ganeti-instance-image
###
IMAGE_NAME=debian-8.4 (<- YOUR OS NAME & VERSION HERE)
ARCH=x86_64
IMAGE_DEBUG=1
SWAP=yes
###

Here I created new instance and I tried to start the installation from ISO file.
###
gnt-instance add -n ganeti-master -o image+default -t plain -s 10G --net 0:link=kvm-br-public --no-start --no-install vm1
gnt-instance start -H boot_order=cdrom,cdrom_image_path=/home/polo/debian-8.4.0-amd64-netinst.iso vm1
###

output:
###
root@ganeti-master:/home/polo# gnt-instance list
Instance Hypervisor OS            Primary_node  Status  Memory
vm1      kvm        image+default ganeti-master running   128M
###

BUT, when I conected to the VNC console, I saw the message:
"Probing EDD (edd=off to disable)...ok"

It got stuck on this message - the boot process doesnt want to continue. I googled and found out this link:
http://serverfault.com/questions/708447/probing-edd-boot-message-stays-for-ten-minutes-on-centos-6-6

But it didnt help me, I tried to mount the vm disk image and perform the changes, but without success:
###
mount /dev/mapper/data-c2d1a530--8876--4a77--b0d6--d057f948fec3.disk0 /mnt/vm1/
mount: wrong fs type, bad option, bad superblock on /dev/mapper/data-c2d1a530--8876--4a77--b0d6--d057f948fec3.disk0,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.
###

Any ideas how to overcome the problem?
