Xen users - Jun 2012 - why can't i install parted on CentOS distributed with XCP ISO binary?

i am investigating what the XCP installation process did to my hard drive.

when i issue: fdisk -l, i get the following output.

WARNING: GPT (GUID Partition Table) detected on ''/dev/sda''!
The util
fdisk doesn''t support GPT. Use GNU Parted.
WARNING: The size of this disk is 3.0 TB (3000592982016 bytes).
DOS partition table format can not be used on drives for volumes
larger than 2.2 TB (2199023255040 bytes). Use parted(1) and GUID
partition table format (GPT).

/dev/sda1   *           1      266306  2147483647+  ee  EFI GPT

as such, i wanted to run the "parted" command. however, running this
command says "command not found." i tried to install the parted
utility:

yum install parted

but the output was

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Setting up Install Process
No package parted available.
Nothing to do

what''s going on here? what do i have to modify in /etc/yum.repos.d/*
if anything?

any help is appreciated.

That is expected behaviour

Nothing. You''re not supposed to install anything on XCP. Forcing to do
so is unsupported, and might break the system.

Think vmware vsphere hypervisor. Treat XCP the same way.

While XCP userland is 90-something-percent centos, some packages are
modified to be specific to XCP. Had centos repo been enabled, those
packages would be overwritten with, making xcp stop working. So to be
safe, the repositories are disabled.

If you understand the risks and consequences, and pretty sure you want
to do it anyway, you could create your own repo file (or probably just
enable existing ones) temporarily. Or just download and copy the RPMS
manually (there should only be several needed for parted and its
dependencies).

Don''t complain if anything breaks though.

Fajar, thanks. if that behavior is intentional, then i''ll accept that.
also, thanks for the pointer of "forcing" the install. that really
helps if decide to tinker some more.
