I am trying to bring up a Centos 6.6
qcow2 image on my virt-manager.
Booting from Hard disk....
Probing EDD (edd=off to disable)... ok
The guest machine stays with the above message for near ten minutes. How can i disable EDD probing in the qcow2 image?
I can see, people's discussion to fix this using boot time setting, linux edd=off
.
But virt-manager gui doesn't have an interface to set boot options.
Is there any setting, i can tweak after logging into the machine – so that EDD probing may not happen for further logins.
Best Answer
You don't have to set this in
virt-manager
.Add
edd=off
to the first(!)kernel
line inside the VM in/boot/grub/grub.conf
, e.g. like so:I say only to the first line as you can then use an alternative menu entry if this creates problems, and also because the options used in this line will also be used for newer kernels installed by updates.
For a first test, you can also connect to the VM console, either with
virt-manager
or a VNC client and presse
foredit
in the Grub boot menu and then add this option to the kernel command line.
