Re: [Xen-API] What is XCP iso 'under-the-hood'?

[Andrew Eross <eross@xxxxxxxxxxxx>]

Hey Andreas,

Sure -- yum is a package installer like apt.

yum --enablerepo=base --disablerepo=citrix install <PACKAGE>

In my example I mentioned screen.

This just means it disables the citrix updates repo and enables the base centos repo for searching for the desired package.

Here's a better explanation by way of example, just check out what's in the available repos list.

I did this on a dom0:

cd /etc/yum.repos.d/

[root@vh04 yum.repos.d]# ls -al

total 32

drwxr-xr-x  2 root root  4096 Sep 25 21:28 .

drwxr-xr-x 62 root root  4096 Dec 13 10:13 ..

-rw-r--r--  1 root root  2020 Sep 25 21:28 CentOS-Base.repo

-rw-r--r--  1 root root   631 Aug 29  2011 CentOS-Debuginfo.repo

-rw-r--r--  1 root root   626 Aug 29  2011 CentOS-Media.repo

-rw-r--r--  1 root root  5390 Aug 29  2011 CentOS-Vault.repo

-rw-r--r--  1 root wheel  264 Sep 25 21:28 Citrix.repo

[root@vh04 yum.repos.d]# cat Citrix.repo
